Scope of Manual

This instruction manual provides information on instal-

lation, adjustment, maintenance, and parts ordering for

the Type 657 actuator in sizes 80 and 100. Refer to

separate instruction manuals for information about oth-

er equipment and accessories used with these actua-

tors.

Only personnel qualified through training or experience

should install, operate, and maintain a Type 657 ac-

tuator. If you have any questions about these instruc-

tions, contact your Fisher Controls sales office or

sales representative before proceeding.

Description

The Type 657 actuator (figure 1) is a direct-acting,

spring-opposed diaphragm actuator used for automat-

ic operation of control valves. The actuator positions

the valve plug in response to varying pneumatic load-

ing pressure on the diaphragm. Figure 2 shows the

operation of these actuators.

A Type 657 actuator can be furnished with either a

top-mounted or side-mounted (size 80 only) hand-

wheel assembly. A top-mounted handwheel assembly

is normally used as an adjustable-up travel stop. The

size 100 top-mounted handwheel may be used as an

auxiliary manual actuator. A side-mounted handwheel

assembly is normally used as an auxiliary manual ac-

tuator.

Specifications

Refer to table 1 for specifications of the Type 657 ac-

tuator. See the actuator nameplate (figure 3) for infor-

mation about a specific actuator.



WARNING

To avoid personal injury or parts dam-

age, do not exceed the Maximum Dia-

phragm Casing Pressure listed in table

1. The Maximum Diaphragm Casing

Pressure must not produce a force on

the actuator stem greater than the maxi-

mum allowable actuator output thrust or

the maximum allowable stem load.

Type 657 Sizes 80 & 100

When an actuator and valve body are shipped togeth-

er, the actuator is normally mounted on the valve. Fol-

low the valve body instructions when installing the

control valve in the pipeline. If the actuator is shipped

separately or if it is necessary to mount the actuator

on the valve, perform the

Actuator Mounting

proce-

dures as described below.

For information on mounting valve positioners, refer to

the appropriate valve positioner instruction manual.

Actuator Mounting

1. To permit adjustment of the actuator spring, the

size 100 actuator must be installed in a vertical posi-

tion above the valve body. Mount the actuator on the

valve bonnet. Insert the cap screws, and tighten the

hex nuts, securing the actuator to the bonnet.

2. Screw valve stem locknuts (key 16, figure 5) all the

way onto valve stem thread.

3. Connect an air supply to the diaphragm casing.

4. For push-down-to-close valves, be sure the valve

plug is on its seat. apply pressure to ensure that the

actuator stem is fully extended. Reduce actuator load-

ing pressure to retract the stem approximately 1/8 inch

(3.2 mm).

5. For push-down-to-open valves, move valve plug to

closed position. On large body sizes, this may require

the use of a pry bar inserted through the body line

opening. If the body is installed in a pipeline, the bot-

tom flange (if one is used) can be removed and the

valve plug pushed to the seat from the bottom open-

ing. Pressure the actuator to move the stem out 1/8

inch (3.2 mm).

WARNING

To avoid personal injury due to the sud-

den uncontrolled movement of parts, do

not loosen the stem connector cap

screws when the stem connector has

spring or loading pressure force applied

to it.

CAUTION

Incomplete engagement of both valve

stem and actuator stem in the stem con-

nector can result in stripped threads or

improper operation. Be sure that the

length of each stem clamped in the stem

connector is equal to or greater than the

diameter of that stem.

Figure 3. Type 657 Actuator Nameplate

12B6508-A/ DOC

6. Clamp the actuator and valve plug stems between

the two stem connector halves (key 26, figure 5). In-

sert and tighten the stem connector cap screws.

7. Thread the stem locknuts against the stem connec-

tor.

8. Align the travel indicator scale (key 18, figures 5

and 6) to show valve position.

Loading Connection

1. Connect the loading pressure piping to the connec-

tion in the top of the diaphragm casing.

2. Remove the 1/4-inch bushing (key 33, figure 5 and

key 120, figure 6) to increase connection size, if nec-

essary. The connection can be made with either piping

or tubing.

3. Keep the length of tubing or piping as short as pos-

sible to avoid transmission lag in the control signal. If

an accessory (such as a volume booster or valve posi-

tioner) is used, be sure that the accessory is properly

connected to the actuator. Refer to the positioner in-

struction manual as necessary.

4. Cycle the actuator several times to check that the

valve stem travel is correct and that the travel occurs

when the correct pressure range is applied to the dia-

phragm.

5. If valve stem travel is incorrect, refer to the

Travel

procedure in the

Adjustments

section.

6. If the pressure range is incorrect, refer to the

Spring

procedure in the

Adjustments

section.



Travel

Make travel adjustments when the motion observed

during actuator travel is different from the travel

stamped on the actuator nameplate (figure 3). If the

Actuator Mounting

procedure was followed correctly,

this adjustment should not be necessary.

When adjusting travel of a reverse-acting (push-down-

to-open) valve, apply a slight pressure on the actuator

diaphragm. This moves the valve plug off the seat,

reducing the chance of damaging the valve plug or

seat during adjustments.

Type 657 Sizes 80 & 100

1. Back the stem locknuts away from the stem con-

nector, and slightly loosen the stem connector cap

screws.

CAUTION

Do not use wrenches or other tools di-

rectly on the valve stem. Damage to the

stem surface and subsequent damage

to the valve packing may result.

2. Tighten the locknuts together, using a wrench, then

screw the valve stem either into the stem connector to

lengthen travel or out of the stem connector to shorten

travel.

3. Cycle the actuator to check the travel. If actual

travel is not equal to the specified travel, adjust and

check travel until correct. Tighten the stem connector

cap screws when correct travel is obtained.

4. Raise the travel indicator disk by threading the

stem locknuts against the stem connector.

Spring

Make spring adjustments when the loading pressure

range applied to achieve specified travel is not equal

to the pressure range stamped on the actuator name-

plate (figure 3). Refer to the Bench Set pressure range

on the nameplate when the valve contains no pressure

and the packing is loosely inserted in the bonnet. Re-

fer to the Max. Allow. Supply on the nameplate when

the valve is controlling the specified pressure drop and

the packing is tightened to stop leaks around the stem.

Monitor loading pressure carefully when making ad-

justments. Do not exceed the pressure specifications

of either the loading regulator or the actuator casings.

Each actuator spring has a fixed pressure span.

Changing the spring compression shifts the span up or

down to make valve travel coincide with the loading

pressure range.

Size 80

Remove cover band (key 60, figure 5), insert a rod of

approximately 1/2-inch (12.7 mm) diameter into a hole

in the adjusting screw (key 12, figure 5), and rotate the

adjusting screw with the rod. Rotating the screw from

left to right will increase the loading pressure required

to start actuator stem travel; opposite rotation will de-

crease the pressure required to start travel.

CAUTION

The actuator must be in the vertical

position when adjusting spring to avoid

damage to thrust bearing (key 35, figure

6) and to properly position spacers re-

quired for adjustment.

Remove the shroud plate (key 107, figure 6), and loos-

en the jam nut (key 115, figure 6).

For small spring forces, adjustments can be made by

rotating the adjusting nut (key 114, figure 6). Clock-

wise rotation (when viewed from diaphragm casings)

of the adjusting nut will increase the loading pressure

required to start actuator stem travel, and counter-

clockwise rotation will decrease the pressure required

to start travel. Tighten the jam nut when adjustment is

complete.

For high spring forces, it is necessary to use spacers

between the lower diaphragm casing and the spring

seat to isolate spring force from the adjusting nut.

WARNING

To avoid personal injury from the com-

pressed actuator spring snapping back

to its original length, make and use the

spacers by following the instructions in

the steps below.

1. It is recommended that three spacers be made of

3-inch schedule 80 pipe cut to the appropriate length

specified in step 2. If other than the recommended

material is to be used, be certain that the spacers are

capable of withstanding the spring force involved. The

spacers must be of equa

l l

ength with ends cut squarely.

Type 657 Sizes 80 & 100

2. Measure dimension B as shown in figure 4. Cut

length of spacers as follows:

a. If it is desired to decrease spring compression,

make the spacers approximately 3/16-inch (4.8

mm) longer than dimension B.

b. If it is desired to increase spring compression,

make the spacers approximately 3/16-inch (4.8

mm) shorter than either dimension B plus the

amount of adjustment required or dimension B plus

valve travel, whichever is less.

3. Whenever the total amount of adjustment required

is greater than valve travel, the adjustment must be

made in two or more steps, and the amount of adjust-

ment taken in each step must be less than valve trav-

el.

4. Pressure the actuator to attain full travel. Cautious-

ly insert the spacers at equal intervals around the

spring seat (key 11, figure 6). The spacers must be

seated squarely when in use or they may slip out of

position. Keeping hands and tools away from the

spring and spring seat, slowly decrease loading pres-

sure until the spring force holds the spacers firmly be-

tween the spring seat and lower diaphragm casing

(key 5, figure 6).

5. Loosen the jam nut. The adjusting nut can now be

rotated clockwise (when viewed from the diaphragm

casings) to increase the loading pressure required to

start actuator stem travel or counterclockwise to de-

crease the pressure required to start travel.

6. Pressure the actuator to move the spring seat

away from the spacers, and carefully remove the

spacers.

7. If the total adjustment required was greater than

valve travel, repeat the procedure. It will be necessary

to make new spacers using the new dimension B and

the remaining adjustment required or valve travel,

whichever is less. Tighten the jam nut when adjust-

ment is complete.



Actuator parts are subject to normal wear and must be

inspected and replaced when necessary. The frequen-

cy of inspection and replacement depends on the se-

verity of service conditions. Because of the care

Fisher Controls takes in meeting all manufacturing re-

quirements (such as heat treating and dimensional

tolerances), use only replacement parts manufactured

or furnished by Fisher Controls.

WARNING

Avoid personal injury or property dam-

age from sudden release of process

pressure or bursting of parts. Before

performing any maintenance opera-

tions:

DDisconnect any operating lines pro-

viding air pressure, electric power, or a

control signal to the actuator. Be sure

the actuator cannot suddenly open or

close the valve.

DUse bypass valves or completely

shut off the process to isolate the valve

from process pressure. Relieve process

pressure from both sides of the valve.

Drain the process media from both

sides of the valve.

DVent the power actuator loading

pressure and relieve any actuator spring

precompression.

DUse lock-out procedures to be sure

that the above measures stay in effect

while you work on the equipment.

The maintenance instructions are divided into four

sections: actuator (sizes 80 and 100); side-mounted

handwheel assembly (manual operator); hydraulic

snubber; and top-mounted handwheel assembly (ad-

justable-up travel stop).

Actuator

This procedure describes how the actuator can be

completely disassembled and assembled. When in-

spection or repairs are required, disassemble only

those parts necessary to accomplish the job; then,

start the assembly at the appropriate step.

Key numbers refer to figure 5 for size 80 actuators and

figure 6 for size 100 actuators.

Size 80 Disassembly

1. Bypass the control valve. Reduce the loading pres-

sure to atmospheric, and remove the tubing or piping

from the top of the diaphragm casing (key 1).

WARNING

To avoid personal injury from the pre-

compressed spring force thrusting the

upper diaphragm casing (key 1) away

from the actuator, relieve spring com-

pression (step 2, below), and carefully

remove casing cap screws (key 22) (step

4, below).

Type 657 Sizes 80 & 100

2. Remove cover band (key 60). Insert a rod of

approximately 1/2-inch (12.7 mm) diameter into a hole

in the adjusting screw (key 12), and rotate the adjust-

ing screw from right to left until spring compression is

relieved. If the actuator has a handwheel, rotate it

counterclockwise, relieving all spring compression.

3. If necessary, the entire actuator may be removed

from the valve body by unscrewing two cap screws

from stem connector (key 26) and removing actuator-

to-bonnet bolting.

4. Unscrew diaphragm casing cap screws and nuts

(keys 22 and 23), and lift off upper diaphragm casing

(key 1).

5. Remove the molded diaphragm (key 2).

6. For actuators without snubber, remove diaphragm

plate and stem (keys 4 and 10) as an assembly. This

assembly can be broken down further, if necessary, by

removing the cap screw (key 3).

7. For actuators with snubber (see figure 7), unscrew

cap screw (key 3), and remove diaphragm plate (key

4). Remove stem connector (key 26). Unscrew cap

screws (key 85), and remove cylinder assembly (key

74) and attached stem and upper seat (keys 10 and

90) from actuator.

To disassemble snubber:

a. Unscrew stem from piston/piston rod assembly

(key 27).

b. Remove retaining rings, cylinder heads, and

piston/piston rod assembly (keys 76, 75, and 27).

Replace packing and O-rings (keys 103, 104, 77

and 105) as required.

8. Remove actuator spring, upper sleeve, and spring

seat (keys 6, 34 and 11).

9. Unscrew cap screws and nuts (keys 62 and 63),

and remove spring case (key 29). Cap screws (key

62) on units with side-mounted handwheel do not use

hex nuts (key 63).

10. For actuators without side-mounted handwheel,

remove adjusting flange (key 36) and attached thrust

bearing and adjusting screw (keys 35 and 12).

11. For actuators with side-mounted handwheel (see

figure 7), unscrew cap screws (key 64), and remove

adjusting flange (key 36) and attached thrust bearing

and adjusting screw (keys 35 and 12). Do not lose the

key (key 47).

Size 80 Assembly

1. Coat the threads of the adjusting flange (key 36)

with Never-Seez Nickel Special lubricant (key 244) or

equivalent. Replace the adjusting flange, adjusting

screw, and thrust bearing (keys 36, 12, and 35). Pack

bearing with Lubriplate MAG-1 lubricant (key 241) or

equivalent.

For actuators with side-mounted handwheel, install the

key (key 47) on the adjusting flange (key 36). Coat the

adjusting flange threads with Never-Seez Nickel Spe-

cial lubricant or equivalent. Install the adjusting flange

so that the key engages the slot in the lower sleeve.

Secure adjusting flange with cap screws (key 64). Ad-

just set screws (key 40, figure 7) to eliminate free play

in handwheel bearings.

Note

Over-tightening the set screws will make

handwheel operation difficult.

2. Mount the spring case (key 29) to the yoke (key 9)

using cap screws and hex nuts (keys 62 and 63).

3. Position the lower spring seat (key 11), and slide

the actuator spring (key 6) squarely onto the spring

seat.

4. If the diaphragm plate and actuator stem (keys 4

and 10) were separated, fasten them together using

the cap screw (key 3).

For actuators without a hydraulic snubber, slide

upper sleeve (key 34) onto the actuator stem, and

then slide upper sleeve, actuator stem and diaphragm

plate into the spring case (key 29) so that the spring

(key 6) fits squarely between the diaphragm plate and

the spring seat (key 11).

For actuators with a snubber, thread the actuator

stem and upper spring seat (keys 10 and 90) into the

piston/piston rod assembly (key 27). Install the snub-

ber assembly and attached actuator stem into the up-

per sleeve, spring case adaptor, and spring case (keys

34, 72, and 29). Secure with cap screws (key 85).

5. Place the diaphragm (key 2) with pattern side fac-

ing away from the diaphragm plate (key 4). Align the

holes in the diaphragm and the lower diaphragm cas-

ing (key 5).

6. Position the upper diaphragm casing (key 1) on the

diaphragm (key 2), and align the holes.

Note

When you replace actuator diaphragms

in the field, take care to ensure the dia-

phragm casing bolts are tightened to

the proper load to prevent leakage, but

not crush the material. Perform the fol-

lowing tightening sequence with a

manual torque wrench for size 80 and

100 actuators.

Type 657 Sizes 80 & 100

CAUTION

Over-tightening the diaphragm casing

cap screws and nuts can damage the

diaphragm. Do not exceed 50 lbfSft (68

NSm) torque.

Note

Do not use lubricant on these bolts and

nuts. Fasteners must be clean and dry.

7. Insert the cap screws (key 22), and tighten the hex

nuts (key 23) in the following manner. The first four

hex nuts tightened should be diametrically opposed

and 90 degrees apart. Tighten these four hex nuts to

25 lbfSft (34 NSm).

8. Tighten the remaining hex nuts in a clockwise,

criss-cross pattern to 25 lbfSft (34 NSm).

9. Repeat this procedure by tightening four hex nuts,

diametrically opposed and 90 degrees apart, to a

torque of 50 lbfSft (68 NSm).

10. Tighten the remaining hex nuts in a clockwise,

criss-cross pattern to 50 lbfSft (68 NSm).

11. After the last hex nut is tightened to 50 lbfSft (68

NSm), all of the hex nuts should be tightened again to

50 lbfSft (68 NSm) in a circular pattern around the bolt

circle.

12. Once completed, no more tightening is recom-

mended.

13. Mount the actuator on the valve in accordance

with the procedures in the

Installation

section.

Size 100 Disassembly

Key numbers used in the following procedure are

shown in figure 6 except when indicated.

Note

Two construction variations of the size

100 are based on spring length. Group 1

springs have a free length of 33-1/4

inches (845 mm), and group 2 springs

have a free length of 16-1/2 inches (419

mm).

WARNING

To avoid personal injury from the precom-

pressed spring force thrusting the upper

diaphragm casing (key 1) away from the

actuator, relieve spring compression (step

1, below), and carefully remove casing cap

screws (key 22) (step 7, below).

1. Remove shroud plate (key 107), loosen jam nut

(key 115), and rotate adjusting nut (key 114) until

spring compression is relieved.

Note

To relieve spring compression when

high spring forces exist, refer to the Ad-

justing Actuator Spring section, and fol-

low the instructions given for size 100

actuators with high spring forces.

2. Remove the pressure tubing or piping from the top

of the diaphragm casing.

3. For actuators with top-mounted handwheel, rotate

handwheel (key 51, figure 9) counterclockwise as far

as it will go, unscrew cap screws (key 109, figure 6),

and remove handwheel and gear case assembly (key

65, figure 9).

4. For actuators without top-mounted handwheel, un-

screw cap screws (key 109), and remove diaphragm

casing cover (key 123).

5. If necessary, remove the actuator from the valve

body by separating the stem connector (key 26) and

removing the actuator-to-bonnet bolting. Separate the

stem connector by loosening the stem locknuts (key

16) and unscrewing the four cap screws.

6. Unscrew and remove actuator stem extension (key

116).

7. Unscrew cap screws (key 22), and remove upper

diaphragm casing (key 1).

8. Remove backup plate, diaphragm retainer, dia-

phragm, diaphragm plate, and washer (keys 13, 110,

2, 4, and 117).

9. Unscrew the nuts that attach lower diaphragm cas-

ing (key 5) to actuator tie rods (key 21).

10. Remove lower diaphragm casing from tie rods

and remove hex jam nut, adjusting nut thrust bearing

(used with group 1 springs only), and spring seat (keys

115, 114, 35, and 11).

11. Remove seal bushing (key 111) and diaphragm

casing cover O-rings (keys 112 and 113) from upper

diaphragm casing (key 123). Replace with new parts if

necessary. Apply Lubriplate MAG-1 lubricant or equiv-

alent to the O-rings.

12. Remove actuator spring (key 6).

Note

Before installing diaphragm plate (key

4), rotate adjusting nut (key 114) until

the top of the actuator stem is 10-3/8

inches (264 mm) above the inside sur-

face of the lower casing (key 5).

When installing diaphragm (key 2), be

certain that the rubber side of the dia-

phragm faces away from the spring.

Smooth the edge of the diaphragm to

avoid wrinkling, and be careful that the

diaphragm fold does not get pinched

when the upper casing (key 1) is

installed.

5. Install washer, diaphragm plate, diaphragm, dia-

phragm retainer, and backup plate (keys 117, 4, 2,

110 and 13).

6. Apply Lubriplate MAG-1 lubricant (key 241) or

equivalent to the thread on the diaphragm end of the

actuator stem (key 10).

7. Position the upper diaphragm casing (key 1) on the

diaphragm (key 2), and align the holes.

Note

If backup plate (key 13) interferes with

installation of upper casing, rotate ad-

justing nut (key 114) to move the plate.

Note

When you replace actuator diaphragms

in the field, take care to ensure the dia-

phragm casing bolts are tightened to

the proper load to prevent leakage, but

not crush the material. Perform the fol-

lowing tightening sequence with a

manual torque wrench for size 80 and

100 actuators.

CAUTION

Over-tightening the diaphragm casing

cap screws and nuts can damage the

diaphragm. Do not exceed 50 lbfSft (68

NSm) torque.

Note

Do not use lubricant on these bolts and

nuts. Fasteners must be clean and dry.

8. Insert the cap screws (key 22), and tighten the hex

nuts (key 23) in the following manner. The first four

hex nuts tightened should be diametrically opposed

and 90 degrees apart. Tighten these four hex nuts to

25 lbfSft (34 NSm).

9. Tighten the remaining hex nuts in a clockwise,

criss-cross pattern to 25 lbfSft (34 NSm).

10. Repeat this procedure by tightening four hex nuts,

diametrically opposed and 90 degrees apart, to a

torque of 50 lbfSft (68 NSm).

11. Tighten the remaining hex nuts in a clockwise,

criss-cross pattern to 50 lbfSft (68 NSm).

12. After the last hex nut is tightened to 50 lbfSft (68

NSm), all of the hex nuts should be tightened again to

50 lbfSft (68 NSm) in a circular pattern around the bolt

circle.

13. Once completed, no more tightening is recom-

mended.

14. Install the actuator stem extension (key 116), dia-

phragm casing cover O-rings (keys 112 and 113), and

seal bushing (key 111). Install the gear case cover

(key 123) or the handwheel assembly (see figure 9).

15. Mount the actuator on the valve, and secure with

the actuator-to-bonnet bolting. Refer to the

Installation

section to connect actuator stem to valve plug stem.

Size 80 Side-Mounted Handwheel

The side-mounted handwheel assembly (figure 7) is

normally used as a manual operator. The handwheel

Type 657 Sizes 80 & 100

can be mounted in either of two positions so that, re-

gardless of valve plug action, counterclockwise rota-

tion always opens the valve. The assembly is a contin-

uously connected type with an indicator to show

neutral position. By rotating handwheel away from

neutral, the handwheel can be used to limit travel in

either direction but not both directions at the same

time.

A grease fitting is provided on the gear box for periodic

gear lubrication with a general-purpose grease.

Instructions are given below for complete disassembly

and assembly. Perform the disassembly only as far as

necessary to accomplish the required maintenance;

then, begin the assembly at the appropriate step.

Key numbers refer to figure 7.

Size 80 Side-Mounted Handwheel:

Disassembly

1. Complete steps 1 through 9 of the disassembly

portion of the size 80 actuator section.

2. Unscrew cap screws (key 64), and remove adjust-

ing flange (key 36). Do not lose the key (key 47).

3. Unscrew the two screws (key 28), and remove

travel stop indicator (key 58) from lower sleeve (key

46).

4. Turn handwheel (key 51) to raise lower sleeve.

Continue turning handwheel until lower sleeve is free

of worm gear (key 44). Lift out lower sleeve, bearing

and gear retainer, thrust bearings, and worm gear

(keys 46, 66, 67, and 44).

5. The worm shaft (key 45) and associated parts can

be removed in order to replace or lubricate them. First,

remove the handwheel cap (key 54) and the hand-

wheel (key 51). Do not lose the small ball or spring

(keys 55 and 56).

6. Loosen the two set screws (key 41), and unscrew

the two worm retainers (keys 48 and 49). The ball

bearings (key 50) will come out with the retainers. Re-

move the worm shaft (key 45).

Size 80 Side-Mounted Handwheel:

Assembly

1. Pack the ball bearings (key 50) with Lubriplate

MAG-1 lubricant or equivalent, and insert one ball

bearing in the back worm retainer (key 49) as shown

in figure 7 (section C-C).

2. Thread the back worm retainer and ball bearing

(keys 49 and 50) into the gear case. Align the slot in

the worm retainer with the set screw hole in the gear

case, insert the set screw (key 41), and tighten it.

3. Coat the worm shaft (key 45) threads with Never-

Seez Nickel Special (key 244) or equivalent lubricant,

and slide the shaft into the gear case so that the end

of the shaft fits snugly in the back worm retainer.

4. Insert the bearing in the front worm retainer (key

48), and thread the retainer and ball bearing into the

gear case. Align the slot in the retainer with the set

screw hole in the gear case, insert the set screw (key

41), and tighten it.

5. Put the spring and ball (keys 56 and 55) in the

handwheel (key 51). Slide the handwheel onto the

worm shaft (key 45). Thread the handwheel cap (key

54) onto the worm shaft.

6. Pack the two thrust bearings (key 67) with Lubri-

plate MAG-1 or equivalent lubricant. Install one thrust

bearing; then, install the worm gear (key 44) followed

by the second thrust bearing and the bearing and gear

retainer (key 66).

7. The lower sleeve (key 46) has two screw holes in

one end. Coat the sleeve threads with Lubriplate

MAG-1 or equivalent lubricant, slide the end of the

lower sleeve with the holes into the thrust bearing (key

67), turn the handwheel, and feed the sleeve through

the worm gear. Continue turning the handwheel until

the lower sleeve protrudes from the gear case. Fasten

the travel stop indicator (key 58) to the sleeve with the

two machine screws (key 28).

8. Install the key (key 47) on the adjusting flange (key

36). Coat the adjusting flange threads with Never-

Seez Nickel Special (key 244). Install the adjusting

flange so that the key engages the slot in the lower

sleeve. Secure adjusting flange with cap screws (key

64).

9. Adjust set screws (key 40) to eliminate free play in

the bearings.

Note

Over-tightening the set screws will make

handwheel operation difficult.

10. Install the adjusting screw and thrust bearings

(keys 12 and 35). Pack bearings with Lubriplate

MAG-1 (key 241) or equivalent lubricant, and install as

shown in figure 7.

11. Slide the spring case (key 29) into position, and

secure with cap screws (key 62).

12. Complete steps 3 through 8 of the size 80 actua-

tor assembly section.

Size 80 Hydraulic Snubber

The size 80 Type 657 is available with a hydraulic

snubber, as shown in figure 7, to dampen vertical in-

stability of actuator stem movement. The snubber is

adjusted by rotating the adjusting screws (key 83, fig-

ure 7) counterclockwise out of the reservoir (key 79,

figure 7) to increase damping action and clockwise to

Type 657 Sizes 80 & 100

decrease damping action. The adjusting screw on the

right (the lower of the two adjusting screws in section

B-B of figure 7) regulates downward damping action,

and the screw on the left regulates upward damping

action.

Size 80 Top-Mounted Handwheel

CAUTION

If repeated or daily manual operation is

expected, the actuator should be

equipped with a side-mounted hand-

wheel rather than a casing-mounted

travel stop or top-mounted handwheel.

The side-mounted handwheel is de-

signed for more frequent use as a manu-

al operator.

A top-mounted handwheel assembly is normally used

as an adjustable-up travel stop to limit full retraction of

the actuator stem. Turning the handwheel clockwise

turns the handwheel stem (key 133, figure 8) into the

diaphragm casing and forces the pressure block as-

sembly (key 179, figure 8) against the diaphragm and

diaphragm plate. Instructions are given below for com-

plete disassembly and assembly. Perform the disas-

sembly only as far as necessary to accomplish the

required maintenance; then, begin the assembly at the

appropriate step.

Key numbers refer to figure 5 for actuator parts and

figure 8 for handwheel parts.

Size 80 Top-Mounted Handwheel:

Disassembly

1. Bypass the control valve. Reduce the loading pres-

sure to atmospheric, and remove the tubing or piping

from the diaphragm casing (key 1).

WARNING

To avoid personal injury from the pre-

compressed spring force thrusting the

upper diaphragm casing (key 1) away

from the actuator, relieve spring com-

pression (step 2, below), and carefully

remove casing cap screws (key 141)

(step 3, below).

2. Remove cover band (key 60). Insert a rod of

approximately 1/2-inch (12.7 mm) diameter into a hole

in the adjusting screw (key 12), and rotate the adjust-

ing screw from right to left until spring compression is

relieved. Rotate handwheel to be sure it is not com-

pressing actuator spring.

3. Unscrew cap screws (key 141), and remove hand-

wheel assembly.

4. Remove hex nut (key 54), and lift off the hand-

wheel.

5. Unscrew support screws (key 182), and remove

pressure block, stem, stem collar, and thrust bearing

(keys 179, 133, 183, and 175).

6. Unscrew body nut (key 186), and remove gland

(key 180). If necessary, remove and replace packing

rings (key 181).

Size 80 Top-Mounted Handwheel:

Assembly

1. Install new packing rings and gland (keys 181 and

180), and thread the body nut (key 186) onto the body.

2. Lubricate the thrust bearing and stem (keys 175

and 133), with Lubriplate MAG-1 (key 241) or equiva-

lent lubricant. Slide stem, stem collar, thrust bearing,

and pressure block (keys 133, 183, 175, and 179) into

the body as shown in figure 8. and install support

screws (key 182).

3. Install handwheel and hex nut (keys 51 and 54).

4. Install a new handwheel gasket (key 185).

5. Mount the handwheel assembly on the diaphragm

casing, and secure with cap screws (key 141).

6. Reconnect pressure tubing or piping to actuator

casing.

Size 100 Top-Mounted Handwheel

A top-mounted handwheel assembly is normally used

as an adjustable-up travel stop to limit full retraction of

the actuator stem. Clockwise rotation of the hand-

wheel (key 51) moves the actuator stem (key 10)

downward, compressing the spring (key 6). Spring ac-

tion returns the stem as the handwheel is turned coun-

terclockwise. Instructions are given below for complete

disassembly and assembly. Perform the disassembly

only as far as necessary to accomplish the required

maintenance; then, begin the assembly at the ap-

propriate step.

Key numbers refer to figure 6 for actuator parts and

figure 9 for handwheel parts.

Size 100 Top-Mounted Handwheel:

Disassembly

1. Bypass the control valve. Reduce the loading pres-

sure to atmospheric (refer to the

Maintenance

sec-

tion), and remove the tubing or piping from the dia-

phragm casing.

Type 657 Sizes 80 & 100

WARNING

To avoid personal injury from the pre-

compressed spring force thrusting the

upper diaphragm casing (key 1) away

from the actuator, relieve spring com-

pression (step 2, below), and carefully

remove casing cap screws (key 124)

(step 3, below).

2. Rotate handwheel counterclockwise, relieving all

spring compression.

3. Unscrew cap screws (key 124), and remove gear

case cover (key 123).

4. Loosen the set screws (key 41) in the front and

back worm retainers (keys 48 and 49) and handwheel

handwheel.

6. Remove front and back worm retainers (keys 48

and 49).

7. Remove worm shaft (key 45).

8. Pull the power screw assembly (key 122). The

bearing and gear retainer, thrust bearing, and worm

gear (keys 66, 67 and 44) will come out with the power

screw.

Size 100 Top-Mounted Handwheel:

Assembly

1. Pack the ball bearings (key 50) with Lubriplate

MAG-1 (key 241) or equivalent lubricant, and insert

one ball bearing into the back worm retainer (key 49).

2. Thread the back worm retainer and ball bearing

into the gear case. Align the slot in the worm retainer

with the set screw hole in the gear case, insert set

screw (key 41), and tighten.

3. Coat the worm shaft (key 45) threads with Lubri-

plate MAG-1 or equivalent lubricant, and slide the

shaft into the gear case so that the end of the shaft fits

snugly in the back worm retainer.

4. Insert the bearing into the front worm retainer (key

48), and thread the retainer and ball bearing into the

gear case. Align the slot in the retainer with the hole in

the gear case, insert the set screw (key 41), and tight-

en.
