SERIES CTS COMPACT GUIDE ROD CYLINDERS
DISASSEMBLY
GUIDE ROD BUSHING
1) Mark top of tool plate to ensure proper orientation to housing for reassembly. Locate wrench on piston rod flats and
remove screw. Remove tool plate and guide rod assembly (guide rods can remain attached to tool plate).
2) Remove retaining rings at both ends of cylinder.
3) Press on rod end to remove plug from retract end.
4) Pull on rod to remove bushing, noting orientation of components and their relationship to ports. See FIGURE 1 for standard
orientation. (Extend end port is typically further from end).
5) Remove all seals, noting orientation. Exercise caution to prevent scratching of the sealing surfaces.
6) Clean and inspect all components. Excessively damaged components should be replaced.

PISTON ROD ASSEMBLY AND BUSHING (extend end) TO BODY
Single Rod Units
1) Lubricate piston rod end and all seals.
2) Check for proper orientation of rod seal in bushing (see FIGURE 2). Assemble bushing onto rod using a turning motion
to work rod seal over rod end.
3) Lightly lubricate cylinder bore and counterbore on extend end.
4) Install piston and bushing into body by applying force evenly to the face of the bushing.
5) Insert retaining ring with sharp edge outward from cylinder. Orient opening of retaining ring toward ports (see FIGURE 2).
Verify proper seating of retaining ring in body.
Double Rod Units
1) Lubricate both piston rod ends and all seals.
2) Check for proper orientation of rod seal in bushing. Assemble bushing onto extend end of piston rod assembly using a
turning motion to work rod seal over rod end.
3) Install piston and bushing into body using a turning motion. This will aid assembly of rod end through bushing on
retract end.
4) Insert retaining ring with sharp edge outward from body. Orient opening of retaining ring toward ports (see FIGURE 2).
Verify proper seating of retaining ring in body.
FIGURE 1
REASSEMBLY
1) Be careful not to cut or damage seals during reassembly.
2) Use a petroleum-based lubricant for the lubrication of air cylinders during reassembly.
PLUG (retract end on single rod units only)
1) Replace and lubricate seal.
2) Lightly lubricate cylinder bore and counterbore on retract end.
3) Install plug in body by applying force evenly to the face of the plug. Check for correct location (retract end) in relationship
to ports. (see FIGURE 1)
4) Insert retaining ring with sharp edge outward from cylinder. Orient opening of retaining ring toward ports (see FIGURE 2).
Verify proper seating of retaining ring in body.
BUSHING (retract end on double rod units only)
1) Replace and lubricate seals. Check for proper orientation of the rod seal in bushing. (see FIGURE 2)
2) Lightly lubricate cylinder bore and counterbore on retract end.
3) Install bushing in body by applying force evenly to the face of the bushing. Check for correct location (retract end) in
relationship to ports. (see FIGURE 1)
4) Insert retaining ring with sharp edge outward from cylinder. Orient opening of retaining ring toward ports (see FIGURE 2).
Verify proper seating of retaining ring in body.

TOOL PLATE TO ROD AND GUIDE RODS
1) Lubricate guide rod bushings in body (see FIGURE 2).
2) Apply liquid threadlocker to guide rod screws and loosely assemble
guide rods to tool plate. Assemble guide rods and tool plate to
body (if rebuilding unit, tool plate and guide rods must be
reassembled with the same orientation to body as when
disassembled).
3) Apply liquid threadlocker to piston rod screw and loosely assemble
rod to tool plate.
4) With tool plate in retracted position, torque guide rod screws to
tool plate per CHART 1. Hand cycle unit to check for free movement.
Loosen and re-torque guide rod screws if binding occurs.
5) With tool plate in retracted position torque piston rod screw to
tool plate per CHART 1. Loosen and re-torque screw if binding
prevents unit from cycling at 20 psi [1.4 bar].
