CYLINDER DISASSEMBLY INSTRUCTIONS
Begin with a clean work area. Make sure all replacement parts are avail-
able and have no visual damage or defects. The following tools and
materials are recommended for proper disassembly and assembly.(Exact
wrench sizes will vary depending on cylinder size)
• Allen wrench set(Inch and Metric)
• Small straight edge screwdriver
• Socket wrench & socket set
• Needle nose pliers
• Tin snips
• Razor Blade
• RheoGel TEK664 grease
For best actuator performance it is recommended that the following
instructions be read and followed carefully.
1. REMOVE BAND CYLINDER FROM MACHINERY
Remove all mounting hardware and air connections. If present, from
the Cylinder Heads(16) and/or Carrier(5).
2. REMOVE BAND CLAMPS

CYLINDER ASSEMBLY INSTRUCTIONS
1. CLEAN AND LUBRICATE
Thoroughly clean all components, particularly the Tube(1) Bore, Tube
Slot, Sealing Band (4) and Dust Band(3). Thoroughly lubricate the
Tube Bore with a thin, uniform layer of RheoGel TEK664 grease.
2. PISTON BRACKET ASSEMBLY
With the Piston Bracket(5) in hand, install the Band Ramps(6), with
small end down, so the ends on each side snaps into the hole of the
Piston Bracket. Slide the Pistons(10) into the Piston Bracket(5) so
the threads on the Piston align with the holes in the Piston Bracket
and secure using Screws(19).
Verify surface of Piston is behind the surface of the
Piston Bracket in both places as shown in diagram.
If not aligned properly the Seal Band(4) life may
be shortened.
Install new lubricated U-Cups (8) (seal lips facing out), and Cushion
Seals(9)(small end facing out).
3. INSTALL SEALING BAND
CAUTION: Metal edges of Sealing Band are sharp. Exercise caution
to avoid injury to yourself while installing. Handle Sealing Band with
care. Do not damage edges while handling.
Insert Sealing Band (4) into Cylinder Tube(1) by laying the
Band out along the length of the actuator and passing it
sideways through the slot in Tube. With rubber side facing
up(ground side facing down), position the Seal Band so there
is enough sticking out the end of the Tube as long as a Piston
Assembly.
4. INSTALL PISTON ASSEMBLY
Place generous amounts of grease around bore of Tube(1) and on
exterior surfaces of both Wear Rings(14) on Pistons(10), U-Cups(8)
and Band Ramps(6).
Create a Seal Band Guide Tool by using the 12-inch length of Seal
Band included with repair kit(without rubber), or cut a short length
of the old Seal Band. (Remove the rubber along the entire length of
the Seal Band Guide Tool if needed.) At one inch from one end of the
Seal Band Guide Tool, bend slightly upward. The bend helps to guide
the Seal Band Guide Tool through the Piston Assembly. Determine
which end of the Piston Assembly is going to be inserted into the
Tube(1) first. Insert the bent end of the Seal Band Guide Tool into
the opposite end of the Piston Assembly. Push the Tool through
the opening between the Band Ramp(8) and Wear Ring(14) on the
Piston Bracket(5) and stopping when the Tool exits the end of the
Piston Assembly.
Place the Seal Band(4) on top of the Seal Band Guide Tool. Insert
the Piston Assembly into the Tube(1) until both U-Cups are captured
by the bore in the Tube. Do not force the Piston Bracket into the
Tube and if the Piston Assembly experiences resistance, use a small
screwdriver to press in the ends of the Band Ramps(6) where enter-
ing the Tube. Allow the Seal Band (4) to pass through the Piston
Assembly. Once the Seal Band is though the Piston Assembly, pull
the Seal Band Guide Tool out of the Piston Assembly. Continue
inserting the Piston Assembly into the Tube until the 2nd U-Cup is
inserted into the bore of the Tube.
Slide new Wipers (12) into the groove on the Piston Bracket(5) until
flush with end. Manually move the Piston Assembly the length of the
Tube until the end of the leading U-Cup extends out of the Tube. Wipe
off any excess grease from the end of the Piston Assembly and the
Tube. Move the Piston Assembly so the U-Cup back into the Tube bore.
Note: If Tube and Piston Assembly were greased properly, excess
grease should be present as the Piston exits the end of the Tube. If
there is no excess grease present, remove the Piston Assembly and
re-grease the Tube, then re-install the Piston Assembly.
5. INSTALL HEADS
CAUTION: Twisting the Head (16) during installation may cut the
O-Ring(17) resulting in excessive leakage during operation.
Install new lubricated O-Ring(17) onto each Head(16). Position
Piston Assembly near the end of the Tube in which the Head is being
installed. Position or trim the Seal Band (4) so 1.25" (31.8mm) is
protruding from the end of the Tube(1). Use a razor blade to cut the
rubber along the end of the Tube then remove all rubber outside the
end of the Tube. Keep the rubber on the Seal Band aligned with the
end of the Head(16). Install Head into Tube using a slight up and
down rocking motion(not side-to-side or twisting) until the Head
is flush with the end of the Tube. Secure Head to Tube by install-
ing Head Screws(15) applying a torque of 190 in-lbs(21.47 N-m).
Verify rubber on Seal Band(4) is still aligned with end of Tube. If not,
use needle nose pliers to pull on Seal Band until aligned. Place Band
Wedge(23) with point of Set Screw down into slot of Head and on
top of Seal Band. Push Band Wedge so it is against the end of the
Tube. Secure Band Wedge with Band Clamp(20), FHCS(22) and Set
Screws(21). Make sure hole in Band Clamp aligns with the Cushion
Needle(25) in Head.
Move Piston Assembly to other end of the Tube and repeat the steps
above to install the other head. Trim Seal Band with tin snips if
needed to achieve 1.25"(31.8mm) from end of Tube. While pulling
Seal Band tightly with needle nose pliers, use razor to cut rubber at
the end of the Tube. Remove rubber from the end of the Seal Band
to the cut just made. Install the Head (16) to the Tube and secure
with the Head Screws(15). Use needle nose pliers to pull on the
Seal Band removing any slack and aligning the rubber on Seal Band
with the end of the Tube. If rubber is past end of Tube, trim excess
rubber. If rubber is not up to end of Tube, pull on Seal Band with
needle nose pliers to remove slack. Secure Seal Band with Band
Clamp, FHCS and Set Screws. Once both ends of the Seal Band
are secured, manually move the Piston Assembly the entire length
of the Tube two times to see if there is any slack or issues with the
Seal Band.
6. INSTALL AND SECURE DUST BAND
Position the Piston Assembly at mid-stroke of the Cylinder. Slide Dust
Band(3) through the upper slot of Piston Bracket(5) and lay on top
of the cylinder tube slot. Position the Dust Band 1.25" (31.8mm)
from each end of Tube. Install End Caps(7) using SHCS (11) into
ends of Piston Bracket(5). Loosen Set Screws(21) and FHCS(22)
on both ends of the Tube. Slide Dust Band (3) between Band
Wedge(23) and Band Clamps(20). Tighten the FHCS then the Set
Screws to secure the Dust Band. Move the Piston Assembly to each
end of the Tube to verify the Dust Band is positioned properly.
7. CHECK ASSEMBLY
Manually push the Piston Assembly back and forth along the entire
length of stroke to make certain that the cylinder is properly assem-
bled before reconnecting to the pneumatic supply. The Piston
Assembly should move consistently with minimal friction along the
stroke. The Dust Band should not kink at end of stroke. If it does,
loosen Set Screws(18) until kinking is eliminated and retighten.
8. REMOUNT THE CYLINDER ONTO THE MACHINE
Be certain any flow controls are in place and adjusted prior to apply-
ing compressed air to the Cylinder.

LUBRICATION AND MAINTENANCE
All Tolomatic MX Band Cylinders are prelubricated at the factory. To
ensure maximum cylinder life, the following guidelines should be followed.
1. Filtration
We recommend the use of dry, filtered air in our products. “Filtered
air” means a level of 10 Micron or less. “Dry” means air should be
free of appreciable amounts of moisture. Regular maintenance of
installed filters will generally keep excess moisture in check.
2 External Lubricators (optional)
The factory prelubrication of Tolomatic Band Cylinders will provide
optimal performance without the use of external lubrication. However,
external lubricators can further extend service life of pneumatic
actuators if the supply is kept constant.
Oil lubricators, (mist or drop) should supply a minimum of 1 drop per
20 standard cubic feet per minute to the cylinder. As a rule of thumb,
double that rate if water in the system is suspected. Demanding con-
ditions may require more lubricant.
If lubricators are used, we recommend a non-detergent, 20cP @
140˚F 10-weight lubricant. Optimum conditions for standard cylinder
operation is +32˚ to +150˚F (+0˚ to 65.5˚C).
NOTE: Use of external lubricators may wash away the factory
installed lubrication. External lubricants must be maintained in a con-
stant supply or the results will be a dry actuator prone to premature
wear.
3. Sanitary Environments
Oil mist lubricators must dispense “Food Grade” lubricants to the air
supply. Use fluids with ORAL LD50 toxicity ratings of 35 or higher
such as Multitherm®PG-1 or equivalent. Demanding conditions can
require a review of the application.
4. Cushion Adjustment
Adjust the Cushion Needles in the Cylinder Heads carefully to obtain
optimum deceleration for your particular application. If there are
questions on proper adjustment, please consult Tolomatic.
SWITCH INSTALLATION AND REPLACEMENT
Place switch in side groove on tube at desired location with "Tolomatic" facing
outward. While applying light pressure to the switch, rotate it such that the switch is
halfway in the groove. Maintaining light pressure, rotate the switch in the opposite
direction until the switch is fully inside the groove with "Tolomatic" visible. Re-position
the switch to the exact location and lock the switch securely into place by tightening
the screw on the switch.
