GENERAL INSTRUCTIONS
Reciprocating pumps of both the plunger and cup
type are positive displacement in principle. Due to
positive displacement characteristics, problems may
arise through improper installation or application.
When new or unusual installations are planned, or
the material to be pumped is a liquid other than cold
water, the customer should consult the factory for
additional information.
Positive displacement pumps must have a proper
size and operable type of pressure regulating valve
or pressure relief valve piped into the discharge line.
This is mandatory to prevent damage to pump and
piping or possible injury to personnel. Do not install
any valves or shutoff devices in the by-pass line from
pressure regulator to tank or supply.
All pumps should be installed level. For mobile
applications the maximum angle of intermittent
operation should be no more than 5 degrees in any
one direction.
CALIFORNIA PROPOSITION 65 WARNING:
This product and related
accessories contain chemicals known to the State
of California to cause cancer, birth defects or
other reproductive harm.
INSTALLATION
Install suction piping one pipe size larger than suction
tapping in pump. Reduce piping size at pump with a
reducer coupling. A suction surge arrester will assure
smoother operation. Keep suction piping as short
and simple as possible with a minimum of lift when
operating under suction lift conditions. Avoid any high
points in suction line. Suction piping must not have
any air leaks. Check suction piping assembly for leaks
by using 20-80 psi air pressure and soap bubbles or
submerging assembly under water.
Use suction strainer and screen of adequate size
to avoid restriction of pump suction. Strainer mesh
should be sufficiently small to prevent passage of
trash which may lodge under pump valves. Keep
screen clean with a regular maintenance schedule to
avoid starving pump suction. Many pump problems
and most plunger cup failures are directly traceable to
a starved suction condition.
When pumping liquids that are heated, reduce
pump speed to avoid suction problems. Be sure
that discharge line is properly protected by means
of a pressure regulating valve and a discharge surge
arrester of proper size, capacity and pressure rating.
The discharge line should be of comparable size to
discharge tapping in pump. Discharge line velocity
should not exceed 5 feet per second for most
satisfactory operation.
Nozzle capacity or demand should not exceed 90%
of pump capacity for satisfactory regulating valve
operation. Nozzling in excess of this capacity may
cause unstable pressure regulator operation. It is
also preferred to nozzle in excess of 50% of pump
capacity to reduce the rate of erosion or wear on the
regulating valve and seat.
When lower system capacity demands are required,
the pump speed should be reduced by changing drive
ratios. This will reflect savings in power consumption,
while reducing valve wear and extend pump life.
If line shock or water hammer is encountered, a
second surge arrester should be installed in the
discharge line adjacent to the spray gun or nozzles.
Under some conditions it may also be desirable to
isolate pump from piping with a suitable high pressure
hose. This will eliminate transmission of line vibration
to the pump and minimize possible failure of piping,
pipe threads and pump casting.
Never pipe the bypass from a pressure regulating
valve back into the pump suction. When the discharge
line is shut off, the complete bypass is circulated
back into the pump suction with a resulting rapid
temperature rise which will destroy plunger cups and
gaskets.
Avoid freezing by draining all water from pump and
system in cold weather. Make sure that the drive is
adequate for the horsepower required and is properly
aligned and tensioned. With belt drives, the pulley
on both the motor and pump should be located as
closely as possible to the bearing to reduce bearing
and shaft bending loads. Make sure that all bolts,
nuts, set screws and keys are properly tightened and
pump belts and pulleys are properly protected by
guards according to code.
DIRECT DRIVE ENGINE DRIVEN PUMPS
It is desirable to align the Dodge®Para-Flex®
couplings as accurately as possible to minimize
flexing. After any repositioning, recheck both parallel
and angular alignments by mounting indicators,
near the O.D. of the flange, and rotate the shaft 360
degrees. A good installation indicator reading should
exceed .030". Flange should be positioned on shaft
to obtain 3-1/16" measured from adapter to rear of
clamp ring. Adaptor bolts should be torqued to 300lbs
and clamp ring bolts to 400lbs.
STARTING PUMP
Fill pump crankcase with recommended oil to the
level mark on the oil saber. Oil recommendations are
covered in lubrication section of pump instructions.
Replace all drain plugs in pump and piping. Inspect
tank to be sure that no foreign material is in tank
or suction line. Fill tank at least half full or connect

23833A034 06/04/14

suction to water supply. Open valve if present in
suction line. If pumping from a pit, make sure that
suction line is completely submerged. Make sure
all valves, including spray gun or nozzles, are open
in discharge line. Spray gun may be anchored to
discharge back into the tank. Completely back off
pressure adjusting screw on pressure regulating valve.
CAUTION: When pumping from a pit or under a
suction lift condition, remove the cylinder end caps
and pour water into each cylinder. This will assure that
water is present in the cylinder to lubricate cups.
After starting, close discharge valve or spray gun
slowly while watching pressure gauge to make sure
relief valve or unloader is operating properly. Adjust
relief valve or unloader to desired pressure. See
regulator instructions. Cycle nozzles, or gun, on and
off to be sure that pressure adjustment and regulator
operation is satisfactory. Nozzle capacity should
not exceed 90% of pump capacity for satisfactory
regulating valve operation.
LUBRICATION
Fill gear case with Mobilgear 630 or equal additive
to 3-1/2 qts for D35 Series and 5-1/2 qts for D50-60
Series. Maintain oil level at the mark on oil dipstick.
NOTE: After first 30 hours of operation, drain oil from
gear case (preferably drain at operating temperature),
replace plug and fill gear case with kerosene to
normal oil level. Operate at full speed at zero pressure
for two minutes then drain, replace plug and refill
crankcase with new oil. Change oil every 300 hours
thereafter. Check oil level daily and add oil as needed.
ADDITIVES FOR CRANKCASE OIL
Use of molybdenum disulfide (MoS2) is highly
recommended as an additive to the gear case oil in
back geared pumps and speed reducers. The additive
is compatible with all known oils. It appears to be so
effective in reducing wear and friction that power train
life may be doubled between overhauls.
• D35 volume MoS2concentrate or dispersion “M”
for 5% – 6 fl. oz.
• D35 volume MoS2concentrate or dispersion “M”
for 10% – 12 fl. oz.
• D50-60 volume MoS2concentrate or dispersion
“M” for 5% – 9 fl. oz.
• D50-60 volume MoS2concentrate or dispersion
“M” for 10% – 18 fl. oz.
SERVICE
Disconnect electrical leads to motor, or remove spark
plug leads on engine.
REMOVING PLUNGERS: BELL SHAPED
CUPS
Place plunger at front end of cylinder and remove
valve assembly, if required, to provide clearance for
pulling plunger. Remove socket head cap screw,
thread plunger removal tool onto plunger stud and pull
plunger out of cylinder liner.
REPLACING PLUNGER CUPS
(MODELS D35-12D, D50-12, D60-10)
Remove nut from plunger stud and remove worn cup.
Apply non-hardening sealing compound and replace
with new cup. Thread nut back onto plunger stud and
tighten nut to a snug compression loading.
CAUTION: Do not overtighten nut on plunger cup,
as this will cause excessive squeeze at the cup heel
resulting in rapid cup wear.
Before installing the plunger in the cylinder, the ring
gasket seal between the plunger and rod should be
inspected and replaced if worn. Inspect cylinders for
linear grooving and replace cylinders if necessary.
New cups will rapidly cut or wear out in groove
cylinders.
Thread the plunger removal tool onto the plunger stud
making it flush with the plunger nut. Lubricate plunger
cup with Molykote®or Lubriplate®and check to be
sure that the ring gasket is installed in plunger stud.
Retract plunger rod by rotating pump crankshaft.
Install plunger by driving plunger assembly back into
cylinder. Replace plunger rod socket head cap screw.
REPLACING PLUNGERS
V-RING PACKING (MODEL D35-12AVD)
Move plunger to the front end of the cylinder and
remove valve assembly if required to provide
clearance for pulling plunger. Remove cap screw and
with plunger at extended position, back off piston rod
and insert tool until large diameter catches behind
stud. Force plunger assembly from liner by rotating
crankshaft slowly. Inspect cylinders for linear grooving
and replace cylinders if necessary. New packing will
rapidly cut or wear out in grooved cylinders.

23833A034 06/04/14 4
V-rings should be lubricated with Molykote for ease in
assembly. Do not use a graphite type grease.
When installing each V-ring plunger assembly, rotate
crankshaft until piston rod is at the most extended
position. Place copper gasket in position in the stud
and use a small amount of Permatex®to hold in place.
Insert plunger assembly into liner and drive slowly into
place. Cap screw should then be inserted and torqued
to 25 ft/lb.
REPLACING PLUNGERS
SINGLE LIP CUP (MODEL D35-8PP)
Move plunger to front end of cylinder and remove
suction valve if required for clearance for pulling
plunger. Remove socket head cap screw and rotate
crankshaft to retract plunger rod from cylinder. Insert
V-ring packing tool into rear of cylinder and force
plunger assembly from cylinder by slowly rotating
crankshaft. Inspect cylinders for linear grooving and
replace cylinders if necessary. New cups will rapidly
cut or wear out in grooved cylinders.
Grease the O-ring and install in the groove on cup
follower. With a flat plate behind cup, hold the cup
and follower firmly in a vise with follower boss in hole
in cup. Use a thin blunt tool and carefully push entire
circumference of O-ring to the back of the groove
and under the lip of the cup. Assemble all parts onto
socket head cap screw and apply Lubriplate®to the
outside of cup. With plunger rod in forward position,
insert plunger assembly into cylinder and tighten cap
screw.
REPLACING CYLINDER LINERS
Remove plungers and rotate crankshaft until piston
rod is in rear position. Insert puller through the inside
of cylinder and pilot over piston rod. Insert disc into
slots on puller and slip plate over threads on puller.
Screw nut onto thread on puller and snug up. Tighten
nut until liner breaks loose. Loosen nut, slip disc out
of slot and remove puller. Repeat to remove remainder
of cylinder liners.
Reasonable care and judgment should be used
when installing the new tapered cylinder shell. Clean
out any accumulation of loose rust or corrosion in
tapered cylinder slots. Insert shells into position by
hand and drive into position firmly. Never use a hand
or hydraulic arbor press to install cylinder shells. If
extreme pressures are used during installation, parts
will be very difficult to remove for later replacement
and liners may be distorted.
REPLACING SEATS: CENTER POST
VALVES
Remove the valve and cylinder caps which provide
access to both the suction and discharge valves.
Remove the stainless steel shoulder screw, which
serves as a valve guide and spring retainer, spring
and valve from the pump fluid end. Assemble stud,
retainer and three screws. Insert screw heads through
holes in valve seat. Rotate retainer to the right until
heads catch and secure in place by screwing down
stud firmly by hand. Place plate over stud and screw
on nut. Torque slowly until seat breaks loose. Suction
valve seats in similar manner, except two stud lengths
are joined using coupling.
NOTE: Valve seats are usually distorted and cannot be
reused unless face is reground to flat condition.
Inspect tapered valve seat bore in fluid end for rust
and wipe out excess. Place a new lower seat in
tapered hole and drive lower seat firmly into place.
Repeat for upper seat being sure to also inspect
the tapered bore in housing for rust. Reassemble
the valve, spring and spring retainer, and verify that
springs are in correct location. When upper and lower
valve seats are the same size, the heavier spring is
always installed on the upper or discharge valve.
NOTE: Be sure that shoulder screw is bottomed in
valve seat and the valve disc is installed on valve with
flat face down.
Inspect O-ring on valve and cylinder caps. Replace
if they show signs of wear. Lubricate O-rings and
replace cap, bar and nuts.

23833A034 06/04/14
5
REPLACING SEATS: CAGED VALVES
Remove spring retaining bar, spring and flat valve.
When removing upper valve seat, pass head of puller
through hole in valve seat before the slide wedge is
inserted alongside puller bolt. Draw down on the nut
at the top of the bolt. When removing lower seats,
drop puller bolt through opening for upper seat and
remove in same manner using the slide wedge on
pumps where lower seats are same size as upper
seats.
Place new lower seat in tapered hole in cylinder body.
Hold a soft brass or hardwood round bar against
slot and drive into place. The knocker stem is in
two pieces so that it can be shortened for installing
discharge valves after suction valves have been
installed.
REPLACING PLUNGER ROD SEALS
The rod seal assembly contains two seals and two
oil seals with lips facing the power end. The oil seal
can be replaced without taking the fluid end off by
removing the cylinder and piston to allow access to oil
seal housing. Unscrew the two Allen screws and place
them into the other two tapped holes. Gradually screw
them in to push oil seal housing off the retainer. After
assembling new seals in oil seal housing, an assembly
thimble should be used on the end of the crosshead
rod for sliding the oil seal housing back into the
retainer. Check gasket and replace if damaged.
REMOVING CRANKSHAFT AND
PINION SHAFT
Remove plunger assemblies and remove connecting
link caps. Move the link-crosshead assembly as far
forward as possible. On some models, it may be
necessary to remove the fluid cylinder body to obtain
clearance for crankshaft removal.
Secure separation of the crankshaft gear and gear
case so that crankshaft will be held in place against
pinion shaft. Remove both crankshaft bearing caps.
Hold crankshaft at ring gear and left-hand link journal
to prevent dropping into bearing bores and remove
from gear case by moving crankshaft to the right until
left end can be swung free.
To remove pinion shaft, observe inside of gear case
to see if small sheet metal plates are in front of each
bearing. These plates must be removed prior to
the bearing caps.
Tap the end of the pinion shaft extension to remove
the bearing cup at the opposite end. After removing
pinion shaft, the remaining bearing cup can be
removed by gently tapping against the peripheral
edge of the cup with a brass rod.
REPLACING PINION SHAFT AND
SHIMMING BEARINGS
After installing the link-crosshead assemblies and
moving them toward the fluid end as far as possible,
tap the right-hand pinion shaft bearing cup into
position using the bearing cap. Place pinion shaft in
position and tap left-hand bearing cup into place.
Replace sheet metal plates, if used on this model
pump.
Cover the shaft keyway to protect lip of oil seal. Slide
on the open bearing cap with a .030" shim. Tighten
the four cap screws to recommended torque.
Install other cap using total shim thickness. Tighten
cap screws holding pinion or crankshaft caps to gear
case. Rotate pinion shaft back and forth, applying
about 15 lbs. axial force to properly seat tapered
rollers. Measure end-play by using an indicating
gauge.
Subtract recommended end-play (.005"– .009") from
actual end-play. This is the amount of shim that must
be removed. After excess shim thickness has been
removed, replace caps and retighten cap screws.
Measure end-play, and if end-play is not within limits
recommended, add or subtract shims as required.
Pinion bearing shims are made of .002" layers bonded
together. Start separation of layers by heating edge,
then peel back.
REPLACING CRANKSHAFT AND
SHIMMING BEARINGS
Press the bearing cups into the caps. Place one
cap into position on the right side with cap screws
engaged about one turn. Install crankshaft, left end
first, and push both bearing caps into place. Extreme
care should be exercised to avoid damage to gear
teeth, bearings and link journals.
For quiet operation and long life, the crankshaft
and bearings must be installed with .003" to .005"
preload. To adjust, loosen the four cap screws on the
pinion shaft bearing cap. Place about a .045" shim
on the right crankshaft bearing cap and tighten the
five cap screws. Install the left cap without shims
and secure with two cap screws. Torque at 13 ft/lbs
and rotate the crankshaft. Retorque the cap screws.
Repeat three times to properly seat the tapered roller
bearings. Measure the shim gap remaining between
the bearing cap and the gear case. Required shim
thickness for this cap is equal to the average gap
measurement plus .031" for D35 and .022" for D50-60
Series. Insert correct shim thickness under left bearing
cap and tighten cap screws. Next, install connecting
links and caps, and torque cap screws.

23833A034 06/04/14 6
Check for adequate side clearance of links on
crankshaft. Some shims must be moved from one
end to the other until sideways movement of all links
can be seen. Check the torque of cap screws on all
bearing caps.
RECONDITIONED CRANKSHAFTS
When the crank throws are slightly damaged, they can
sometimes be reconditioned for further use. This can
be done by sandpapering and polishing until all ridges
are completely removed. The final polishing operation
should be with very fine emery cloth. If the surface is
badly damaged, the crankshaft can often be salvaged
by “metalizing” the crank throw, regrinding and
polishing to the original diameter.
SERVICING CONNECTING LINKS
The connecting rod link is furnished with replaceable
split sleeve bearing inserts at the crank throw. Do not
attempt to re-fit connecting links to the crankshaft
bearings by filing or grinding the mating faces of the
link cap where it contacts the link. Always be sure
that the proper side of the link is placed upward
when attaching it to the crankshaft. The upper side
contains an oil hole at the crosshead end of the link.
This oil hole must be up to allow proper oil feeding
to the crosshead pin bushing. The wrist pin is then
press-fitted into the crosshead and slip-fitted through
the bronze bushing. Use an arbor press to force in
the wrist pin, checking to see if the link is free to
rotate after the wrist pin is pressed in. Verify that both
sides of the wrist pin do not protrude beyond the
crosshead.
The crosshead end of the connecting link is fitted with
a bronze bushing. New replacement link bushings are
reamed to the proper size for immediate installation.
If the bushing is removed from an old link, it may
be necessary to ream the replaced bushing to the
proper inside diameter after it is pressed into the link.
When placing the bushing on the link, be sure that the
oil holes in the bushing and link are in line after the
bushing is pressed into position.
CROSSHEAD AND PISTON RODS
Repair parts for the crosshead and piston rod are
supplied as a complete unit. If either of these parts
becomes worn, it is necessary to replace both the
crosshead and piston rod. It is not practical to attempt
to tighten a loose piston rod in a crosshead. Under
normal conditions a crosshead will not wear, nor will
the bore of the crankcase wear to the extent that
oversize crossheads will be required. A clearance of
.002" to .004" is standard for the crosshead.

† The parts above are used on newer D35-8PP-2H pumps. It can be differentiated by the follower and
cup. Use 06737A031 if your cup is all rubber and no fabric. The 13046A026 contains fabric and
rubber. Use 20161A000 & 05876A040 O-ring if your follower has an O-ring groove on the outside
diameter. The 20161A001 follower has no groove and does not need an O-ring groove on the
outside diameter. This does not apply to D45-12PP.

1. Pump priming is usually not necessary when the
pump is installed correctly. However, there are certain
conditions which may make it necessary to prime the
pump to get the pumping action started. Priming will be
required when it is impossible for the plunger to displace
the air in the pump and replace it with water. This can be
caused by a high suction lift, the valves being stuck on
the seat or by valves sticking due to extreme corrosion.
A pump will not prime readily if someone has tampered
with the valve springs causing them to exert undue
pressure of the valve plates against the valve seats.
2. A gate valve is sometimes installed in the suction line
between a tank or pressure line and the pump sediment
chamber. It will shut off the supply source in order
to clean the sediment chamber or to perform pump
repairs. If this valve is partially or fully closed, it will
interfere with the flow of water to the pump suction. This
may cause severe knocking and vibration of the pump
because the water cannot flow into the cylinder cavities
fast enough.
3. A sediment chamber should be installed in the suction
line between the gate valve and the pump suction. The
strainers in the sediment chambers are sufficient to
allow a free flow of liquid to the pump. If the strainers
become severely clogged, they will completely stop the
flow of liquid to the pump.
4. Any plunger pump operating at a high pressure will
not perform properly nor quietly if a mixture of air and
water is allowed to enter the pump suction. A small air
leak in the suction line will cause the pump to knock
and vibrate excessively by allowing the pump to draw a
certain amount of water mixed with air on each stroke
of the plunger. A large air leak will cause the pump to
lose prime after which it cannot be reprimed until the air
leak is stopped. Air leaks may occur at the joints of the
suction line piping, at the gate valve in the suction line,
at the gasket sealing the cap on the sediment chamber,
by a crack in the suction wall of the cylinder body or by
air drawing past the plunger cups on the suction stroke
if the plunger cups are badly worn.

5. If the pressure regulator unloading valve is worn, it
will allow too much of the pump capacity to be
bypassed and recirculated back to the tank. By
examining the flow from this valve with the discharge
turned on, it can be determined whether or not the valve
is worn. If a heavy flow continues when the discharge is
turned on, it is usually a good indication of a worn valve
and should be replaced.
6. Worn plunger cups, valves or valve seats will cause a
severe drop in pump capacity pressure. Worn plunger
cups are detected by water leakage past the cups and
immediately should be replaced. Water getting into
the pump crankcase will cause severe corrosion of the
bearings. Worn valves can only be detected by visual
examination of each valve assembly. Abrasive liquid will
cause wire cuts which begin as a very small groove, but
increase rapidly once the valve starts to leak through
this groove. If the valve plates are replaced as soon as
they start to show this cutting action, it will prevent the
valve seat from becoming cut in a similar manner.
7. Pump cylinder bodies withstand an extreme amount
of shock and pulsation while in operation, but if the
pump is allowed to freeze, by not being drained, the
freezing may crack the cylinder body walls in almost
any location. If the crack occurs on the suction valve
or cylinder portion of the body, it may allow a small
amount of air to enter on the suction stroke and cause
noisy operation or a decrease in pumping capacity. If
the crack develops in the walls between the cylinder
cavities or discharge valve cavity, it may allow the water
to flow from one cavity to the adjacent cavity and cause
uneven displacement.
8. The holes in the gun or nozzle discs are continually
subject to wear because of the high velocity of the
liquid through the holes. If the holes become worn, they
may allow a higher rate of discharge than the pump is
able to provide, then a drop in pressure will be noticed.
This can quickly be checked by reducing the number of
nozzles or guns while watching the amount of overflow
from the pressure regulator. If there is considerable
overflow, it is an indication that the regulator valve is
worn rather than the gun or nozzle disc.
9. Suction surge arresters should be installed on the
suction line of reciprocating pumps, 1-1/2" or 2" can
be used. A standing height of 12"-15" will be sufficient
with the top end closed by an ordinary pipe cap.
10. Water may accumulate in the pump crankcase from
two sources; leakage of the plunger cups or an
accumulation of condensation/moisture inside the
crankcase due to changes in weather or the repeated
heating and cooling of the pump. Pumps used
consistently, running for a considerable period of time
to heat the oil and other working parts, will not normally
accumulate water by condensation. Replace the
plunger cups as soon as they start to leak.
11. Worn connecting link bearings are caused by unusual or
adverse operating conditions and are seriously affected
by corrosion if water is present in the crankcase. They
will wear out from overheating if adequate oil is not
provided in the crankcase. It is recommended to drain,
clean and refill with new oil prior to any storage period.
Replace bearings as soon as any damage is discovered
to avoid possible damage to crankshaft.
12. Low oil in the crankcase can quickly cause failure of
the pump's power end and result in extensive repairs.
Oil level should be checked periodically during normal
operation and during all maintenance work.
13. A foaming mixture will sometimes have the same effect
as a small air leak in the suction line. This is because
various quantities of the foam are drawn through the
suction line into the pump disrupting the normal flow of
water.
14. Pressure regulators and unloading valves may become
sluggish in action due to the plunger sticking or fitting
too tightly in its cylinder. This may happen by an
accumulation of chemicals collecting in and around the
plunger or due to excessive corrosion of the plunger
parts. To check this condition, remove and clean the
plunger and cover the parts with a waterproof grease
before assembling.
15. The stuffing box nut on the unloading valve lifting post
should not be tightened to severely grip or bind the
packing on the post. Tighten this nut just enough to
prevent leakage and chatter. The pressure regulator and
unloading valves may chatter or vibrate excessively due
to an unstable operation from nozzling in the high or low
capacity range of the regulator or unloader. The range
should be at least 50% to 90% of pump capacity. With
unloader valves, nozzle capacity should be at least 20%
and not exceed 90% of pump capacity.
16. If foreign matter becomes lodged between the pump
valve and valve seat, a drastic drop in capacity and
considerable surge or pulsation will occur in the
discharge line. Examine each valve if this occurs.
17. When a pump is used for a long period of time, a
waterlogged discharge surge could cause pulsation
at the discharge. The suction should be opened into
the atmosphere to allow air to be drawn through the
pump to recharge the surge arrester. Do this with the
pressure release valve open so the pump operates at no
pressure.
18. Noisy pump operation can be caused by a loose
plunger rod in the crosshead. This noise usually has a
regular cadence timed with each stroke of the plunger.
When this occurs, always replace both the rod and the
crosshead.
19. Increased preload to the crankshaft bearings will reduce
bearing life, require more power and generate more
heat, while insufficient preload may cause a knock,
timed with the crankshaft rotation. Check for loose bolts
on the crankshaft end caps or adjust shims to obtain
proper bearing preload.

24648A000 KIT
Field installation of these kits will require removal of
the fluid end to replace the existing retainer and seals.
On some fluid ends it may be necessary to hand grind
I.D. of fluid end to fit new kit. The same spring and
gasket is used to hold and seal the retainer.
The rod seal assembly contains two seals, and two
oil seals with lips facing the power end. The oil seal
can be replaced without taking the fluid end off by
removing the piston and the cylinder liner to allow
access to oil seal housing. Unscrew two Allen screws
and place into the other two tapped holes. Gradually
screw them in to push the oil seal housing off the
retainer. After assembling new seals in the oil seal
housing, an assembly thimble should be used on the
end of the crosshead rod for sliding oil seal housing
back into the retainer. Check gasket and replace if
damaged. The thimble should be machined from high
carbon steel and polished on the exterior to reduce
the possibility of seal lip damage. Place two Allen
screws into clearance holes and tighten snug.
