During removal and after the piston shaft is removed; DO NOT grasp the
round portion of the shaft with any holding device that will damage the
surface. Any nicks or scratches to the surface will allow hydraulic oil to
leak from the cylinder when the tool is reassembled.
MAINTENANCE SECTION
DISASSEMBLY OF THE TX-2, TX-4, AND TX-8 CYLINDER ASSEMBLIES
1. Place the tool with the slider pin hole over a clearance opening and use a small drift to tap the slider
pin (14) out of the sliders (6) and piston (2).
2. Clamp the housing in copper-covered or leather-covered vise jaws with the inlet end upward, using
a 1/4” hex wrench, unscrew and remove the two swivel assemblies (27) with their attached couplers
(28).
3. Remove the housing assembly from the vise jaws and turn over a container to catch any oil
remaining inside the cylinder.
4. Re-clamp the housing in the vise with the inlet end upward.
5. Use a hex wrench to unscrew and remove the end cover screw (11). Remove the end cover (10).
6. Tap the end cap (7) inward approximately 1/2” and remove the two retaining rings (8) by working
them out of the groove in the cylinder. Note: Covering the oil ports with a cloth will contain any oil
that may expel from the housing.
7. Install the seal insertion tool (40) on the inlet end of the housing. Note: Lubricating the inside of the
insertion tool will ease in the removal of the piston (2) and end cap (7).
8. Invert the tool above the vice. Place a cloth draped between the jaws of the vice to contain the
exiting parts. Spread the vice open enough to catch the end plug and piston.
9. Tap the piston with a brass tap lightly until both the piston and end cap slip through the housing and
into the catch cloth.
10. Use the gland removal tool (41) to unscrew and remove the cylinder gland (20) from the housing.
Note: The TX-2 does not have a cylinder gland.
DISASSEMBLY OF THE TX-16, TX-32 AND TX-45 CYLINDER ASSEMBLIES
1. Clamp the housing in copper-covered or leather-covered vise jaws with the inlet end upward, using
a 1/4” hex wrench, unscrew and remove the two swivel assemblies (27) with their attached couplers
(28).
2. Remove the housing assembly from the vise jaws and turn over a container to catch any oil
remaining inside the cylinder.
3. Re-clamp the housing in the vise with the inlet end upward.
4. Using a socket on the hex of the end cap (7), unscrew and remove the end cap with the end plug
seal.
5. Using a socket on the hex of the piston cap (2B), unscrew and remove the piston cap from the
piston rod (2A).
6. Remove the housing from the vise and turn over a container to empty any remaining oil from the
housing.
7. Re-clamp the housing with the end plug end upward in the vise. Place a cloth between the jaws of
the vice to contain the exiting parts. Gently tap the piston rod (2A) with a brass draft to remove it
from the housing, being careful not to damage the threads.
The purpose of the seal insertion tool in the following step is to prevent
the end plug seal from expanding into the retaining ring groove. If the
tool is not used, place two thin pieces of at stock at the midpoint of the
opening against opposite walls to control the seal expansion.
