Disassembly of the 56586, 56589, 56590 and 56591 Cylinder Assemblies
1. Grasp the housing (1) in copper-covered or leather-covered vise jaws with the inlet end
upward and using a 1/4" hex wrench, unscrew and remove the two swivel inlets (20) with
their attached couplers (21). NOTE: 56586 cylinder uses 16" whip hoses instead of swivels.
2. Remove the housing assembly from the vise jaws and over a container to catch the oil, move
the piston rod assembly (3&4) back and forth several times to purge the hydraulic oil from
the Housing.
3. Grasp the housing in copper-covered or leather-covered vise jaws with the inlet end upward.
4. Insert the pins of the end plug wrench (23) into the holes of the end cap (10). Using a wrench
on the hex of the end plug wrench, unscrew and remove the end cap with the end plug seal
(17). NOTE: the 56586 cylinder requires a 5/8" socket to unscrew and remove the end plug.
5. Push the piston rod far enough into the housing to expose the hex on the piston head.
NOTICE
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.
6. Using a socket on the hex of the piston head, unscrew and remove the piston head from the
shaft with the piston o-ring (19).
7. Pull the piston shaft out of the housing.
8. If the sliders (9) must be replaced, position the slider pin (16) over a clearance opening in a
soft block and use a small drift to tap the pin out of the sliders and shaft.

the assembly.
5. Grasp the ratchet and drive plate (3) and, while maintaining their relationship, lift them both
off the left side plate.
NOTICE
In the following step, 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.
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.
