During removal and after the piston shaft is removed; DO NOT grasp
the round portion of the rod 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.
DISASSEMBLY OF THE TXU-16 CYLINDER ASSEMBLIES
1.
Clamp the housing (1) in copper-covered or leather-covered vise jaws with the uniswivel upward.
Using a hex wrench, unscrew the four uniswivel post screws (20) that clamp the uniswivel to the
housing. Remove the uniswivel and O-rings.
2.
Re-clamp the housing in the vise with the end cap (7) upward.
3. Unscrew the end cap (7) from the housing.
4.
Using a socket on the hex of the piston cap (2B), unscrew and remove the piston cap from the
piston rod (2A).
5.
Remove the housing from the vise and turn over a container to empty any remaining oil from the
housing.
6.
Re-clamp the housing in the vise, end plug end upward.
7.
Remove the piston rod (2A) from the housing. If necessary, tap the threaded end of the piston rod
with a brass tap being careful not to damage the threads. Place a cloth between the jaws of the
vice to contain the exiting parts.
8.
Flip the housing in the vice so that the cylinder gland (17) is visible.
9.
Use the gland removal tool (41) to unscrew the cyclinder gland (17) from the housing.
10.
Place the slider pin in the piston rod over a clearance opening in a soft block, and use a small drift
to tap the pin out of the sliders and piston rod.
MAINTENANCE SECTION
DISASSEMBLY OF THE RATCHET LINK
1.
Lay the ratchet link flat on a workbench with the left side plate (1) downward and using a hex
wrench, unscrew and remove the two lower spacer screws (16).
2.
Using a hex wrench, unscrew and remove the two upper spacer screws (15).
3.
For series TXU-16
: Use a roll pin punch to tap the spacer roll pin (19) out of the right side plate (2).
4.
While applying thumb pressure to the edge of the ratchet (6), carefully lift the side plate off the
assembly.
5.
Grasp the ratchet and drive plate (3) and, while maintaining their relationship, lift them both off the
left side plate.
6.
Push the Ratchet out of the drive plate and remove the drive segment (7) and the segment spring
(14) from the drive plate recess.
7.
If the drive pin (4) or drive pin spring (5) must be replaced, use a roll pin punch to push the drive pin
spring roll pin (18) out of the drive plate. Once the pin spring is removed, the drive pin (4) will drop
down to the large opening at the bottom of the slot for easy removal.
8.
Lift the lower spacer (10) off the lower spacer pins (11). If the pins must be replaced, use a hex
wrench to remove the two lower spacer screws from the right side plate. Pull the pins out of the
holes on the inner face of the right side plate.
When the ratchet is removed from the drive plate, the drive segment
and segment spring will be free to fall from the drive plate recess. Do
not allow the drive segment to fall on a hard surface that might chip the
teeth.
