CYLINDER ASSEMBLY INSTRUCTIONS
1. CLEAN AND LUBRICATE
Thoroughly clean all components, particularly the Tube Bore, Tube
Slot, Sealing Band and Dust Band. Thoroughly lubricate the Tube Bore
with a thin, uniform layer of RheoGel TEK664 grease.
2. PISTON BRACKET ASSEMBLY
With the Piston Bracket (1) in hand, install the Band Ramps (6), with
small end down, so the ends on each side snap into the hole of the
Piston Bracket. Install one Plastic Bearing (8) on each side of Piston
Bracket and between the Band Ramps by snapping ends into holes.
Note, install Plastic Bearings with arrows pointing up. Install the
Pistons (2) into the Piston Bracket (1), with Band Ramp up, until Piston
snaps into hole in Piston Bracket. Install new lubricated U-Cups (3)
(seal lips facing out), and Cushion Seals (4) (small end
facing out). Slide new Wipers (7) into the groove on the
Piston Bracket (1) until flush with end. Trim off excess
flush to other end of Piston Bracket. Wipers need to be
installed with the flare edges facing outward.
3. INSTALL INNER SEAL 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 (19) into Cylinder Tube (26) by laying the Band
out along the length of the actuator and passing it
sideways through the slot in Tube. With flat side facing
up (ground side facing down), position the Band so the
length of band sticking out the end of the Tube is as
long as Piston Assembly. (5 - 10 inches or 12 - 25 cm)
4. INSTALL PISTON ASSEMBLY
Place generous amounts of grease around bore of Tube (26) and on
exterior surfaces of both Pistons (2), U-Cups (3), Band Ramps (6) and
Plastic Bearings (8). Use the 6-inch length of Seal Band included with
repair kit, or a short length of the old Seal Band, slightly kink the Band
upwards, one inch (25mm) from the end. Insert into slot between
the Band Ramp (6) and Piston (2) on the Piston Bracket (1), and stop
against opposite end of the Piston Bracket and up the short length
of inserted Band. Once the Seal Band is through the Piston Bracket,
remove the short length of band material and discard.
Grasp the Piston Bracket while holding the Wipers in place with your fin-
gers. Flare the Wiper edges out, while inserting the Piston Bracket part-
way into the Tube. Do not force the Piston Bracket. Place a finger over
the opposite end of the Piston Bracket to keep the Wipers in place, while
pushing the remainder of the Piston Bracket into the Tube (26). With
the Piston Assembly experiences resistance, use a small screwdriver
to press in the ends of the Band Ramps (6) and the Plastic Bearings
(8) where it enters the Tube. With the Piston Assembly in place, slide
the length of the Tube until the end of the Piston just extends out of the
Tube. Wipe off any excess grease from the end of the Piston and Tube.
Position Piston Assembly so it is fully engaged in the Tube.
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 (10) during installation may cut the
O-ring (14) resulting in excessive leakage during operation.
Install new lubricated O-Ring (14) onto each Head (10). Position Piston
Assembly near the end of the Tube in which the Head is being installed.
Position the Seal Band (19) so .394" (10mm) is protruding from the
end of the Tube (26) and centered with the slot in the Tube. With black
marker, make vertical line where the Seal Band intersects with the Tube
and a horizontal line at the center of the Seal Band and slot. 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 installing Head Screws (24) applying a torque of 10
in-lbs (1.13 N-m). Verify horizontal mark on Seal Band is still centered
to the Tube slot. If not, remove Head and try again until centered. Verify
vertical mark on Seal Band is still aligned with end of Tube. If not, use
needle nose pliers to pull on Seal Band until properly located.
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 .394" (10mm) from end of Tube.
Once 2nd Head is properly installed, verify the horizontal and vertical
marks on Seal Band on 1st Head did not move. If moved, use needle
nose pliers to properly locate Seal Band for both Heads.
6. INSTALL DUST BAND
Position the Piston Assembly at mid-stroke of cylinder. Slide Dust
Band (20) through the upper slot of Piston Bracket (1) and lay on top
of the Cylinder Tube slot. Position the Dust Band .394" (10mm) from
each end of Tube. Install End Caps (5) using Screws (23) into ends of
Piston Bracket (1).
7. SECURE SEAL AND DUST BANDS
In the Head (10) slot, place Seal Band Clamp (12) between Seal
Band (19) and Dust Band (20) positioning end of Seal Band Clamp
against end of Tube (26). Place Dust Band Clamp (13) onto Head
(10) so there is access to the Cushion Needle (15) then secure using
Screws (9). Tighten both Set Screws (18) to secure Dust Band.
Repeat to secure other end.
8. CHECK ASSEMBLY
Manually push the Piston Assembly back and forth along the entire
length of stroke to make certain that the cylinder is properly assembled
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.
9. INSTALL BEARING RAIL (OPTIONAL)
If you completed step 3 in the disassembly procedure follow this
assembly procedure. Place the Tube (26) so the threaded holes on
the side are facing up. Align and place the new Bearing Rail (28a)
with Bearing Blocks (28b) on top of Tube. Start all of the Screws (30)
that hold down the Bearing Rail onto the Tube. Do not tighten. Center
the Bearing Rail along the length and width of the cylinder, making
sure the ends of the Bearing Rail are not past each end of the Tube.
Once the Bearing Rail is positioned, tighten all of the Screws (30) to
secure Bearing Rail to the Tube. Verify the Bearing Blocks (28b) can
slide easily from one end of the Tube to the other.
10. INSTALL THE CARRIER
With the Bearing Rail facing up and the Piston Assembly on the side
facing you, slide the two Bearing Blocks (28b) so they are lined up
with both ends of the Piston Assembly. Place the Carrier (33) over the
top of the two Bearing Blocks aligning the mounting holes. Secure
Carrier to Bearing Blocks using Screws (34). Move Piston Assembly
so it is centered with the Carrier. Attach both Adjustment Plates (29)
with Screws (31) capturing the Carrier (33) between the Adjustment
Plates.
11. CHECK ASSEMBLY
Manually push the Carrier (33) back and forth along the full stroke of
the cylinder. Carrier should move consistently with minimal friction
along the stroke.
12. REMOUNT THE CYLINDER ONTO THE MACHINE
Be certain any flow controls are in place and adjusted prior to
applying compressed air to the cylinder.
