DISASSEMBLY
General Instructions
1. Do not disassemble the tool any further than necessary
to replace or repair damaged parts.
2. Use extra care not to score, nick or damage surfaces
that will contain hydraulic oil under pressure.
3. Whenever grasping a tool in a vise, always use
leather–covered or copper–covered vise jaws to
protect the surface of the part and help prevent
distortion. This is particularly true of threaded
members and housings.
4. Do not remove any part that is a press fit in or on an
assembly unless the removal of that part is necessary
for repairs or replacement.
5. Do not disassemble the hydraulic cylinder assembly
unless you have a complete set of seals and o–rings for
replacement.
6. Use only British Standard fractional size tools when
disassembling these tools.
Disassembly of the Tool
1. Push the Link Pin (12) out of the Housing (1) and Side
Plates (1 & 2).
2. Lift the Housing from between the Side Plates and
separate the two units.
Disassembly of the TX-2, TX-4, and TX-8 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).
2. Remove the Housing Assembly from the vise jaws and
over a container to catch the oil, move the Piston Rod
(3) 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. For TX-2 use a Phillip’s Head screw-driver and TX-4
models, use a hex wrench to unscrew and remove the
End Cover Screw (14). Remove the End Cover (13).
5. Push the End Cap (10) inward approximately ½” and
remove the two Retaining Rings (11) by working
them out of the groove in the Cylinder.
6. Install the Seal Insertion Tool (22) on the inlet end of
the Housing.
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 flat stock at
the midpoint of the opening against opposite walls to
control the Seal expansion.
7. Thread one of the Swivel Inlets or a threaded pipe
with a tee into the End Cap (10). Use the Inlet or tee as
a handle to pull the End Cap and End Plug Seal (17)
out of the Housing through the Seal Insertion Tool.
8. Push the piston end of the Piston Rod forward in the
Housing until the Slider Pin (16) aligns with the
cross holes in the Housing.
9. Using a small drift, tap the Slider Pin out of the
Sliders (9) and position shaft and remove the two
Sliders.
10. Push the piston out of the Housing.
11. If the Rod Seal (18) needs replacement, use a
hooked tool to pull it out of the Housing.
Disassembly of the TX-16, TX-32 and TX-45
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).
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).
5.
Push the Piston Rod far enough into the Housing to
expose the hex on the piston head.
WARNING
TI
E
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.
