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 (36).
2. REMOVE CARRIER FROM CYLINDER
Remove Screws (35) from Carrier (36). Slowly lift up the Carrier and
remove it from the cylinder.
CAUTION:
Contaminating the Bearing Block will hinder the operation of
the cylinder. Do not remove the Bearing Blocks from the Rails. If the
Bearing Blocks need to be replaced so will the Bearing Rail.
Remove Screws (34), Adjustment Blocks (31) and Carrier Bearings (32)
from the cylinder.
3. REMOVE BEARING BLOCKS AND BEARING RAIL (OPTIONAL)
The MX Bearing System is designed to provide maximum life. Should the
Bearing Blocks need replacement, the Bearing Rail will need to be replaced
as well. Bearing Blocks (30b) and Bearing Rail (30a) must remain together.
If the cylinder stroke requires two Bearing Rails to be mounted, the cylinder
will need to be sent to the factory. It is critical that the two Rails are aligned
properly. This requires special fixtures and cannot be done in the field.
To remove both the Bearing Blocks and Bearing Rail, slide each Bearing
Block off one at a time and place in a clean area. Next remove Screws (29)
from the Bearing Rail (30a). Lift up on the Rail and place in a clean area.
4. REMOVE BAND CLAMPS
Loosen Screws (21) on Dust Band Clamp (20). Remove Screws (22)
from Cylinder Heads (16). Remove Seal Band Clamp (23) from
between Dust Band (3) and Seal Band (4). Do not adjust the point Set
Screw in the Seal Band Clamp (23). Repeat for other Cylinder Head.
5. REMOVE DUST BAND
Remove End Caps (7) from both ends of the Piston Bracket (5) by remov-
ing Screws (11). To remove Dust Band (3), lift one end and pull the Band
through the Piston Bracket. The Band is magnetically retained so some
resistance will be present when removing.
6. REMOVE HEADS
Remove the four Head Screws (15) to free each Cylinder Head (16).
Remove each head by rocking it up and down until the head is free from
the Cylinder Tube (1).
DO NOT TWIST!
Remove the O-Ring (17) from
both heads with a small straight edge screwdriver.
7. REMOVE SEAL BAND
CAUTION:
Sealing Band edges are sharp. Grasp the top and bottom of
the Band when removing, not the edges.
Slide Piston Bracket (5) out of the Cylinder Tube (1). Remove the Sealing
Band (3) through the slot in the Tube.
8. DISASSEMBLE PISTON BRACKET
Remove Wipers (12) from the Piston Bracket (5). With the small
straight edge screwdriver, remove the U-Cups (8) from both Pistons (10).
Remove the Cushion Seal (9) from each Piston. Remove the Pistons (10)
by removing Screws (19) then sliding out of Piston Bracket (5). With
a small screwdriver, remove the Band Ramps (6) by disengaging the
side retaining tabs for each. Keep the Piston Bracket (5) and the two
Pistons (10) for reassembly.
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
