UIDELINES
During disassembly and assembly, take the following
precautions to avoid damaging tool or components:
a. Always work on a clean surface.
b. Use relatively soft materials, such as brass,
aluminum, or wood to protect the tool when applying
pressure.
c. Apply a continuous strong pressure, rather
than sharp blows, to disassemble or assemble
a component. An arbor press provides steady
pressure to press a component in or out.
d. Never continue to force a component if it “hangs
up” due to misalignment. Reverse the procedure to
correct misalignment and start over.

or equivalent, on O-rings and mating surfaces to aid
assembly and prevent damage to O-rings.
A special Spanner Wrench is available from Huck to
aid in the disassembly and assembly of Locking Ring,
reference No. 11. A Piston Rod Guide is available
to prevent damage to the piston rod seals when
assembling the piston. See

CCESSORIES
.
Standard hand tools, such as wrenches, drifts, copper
or lead hammers, screwdrivers, socket screw hexagon
keys, long forceps (tweezers), etc. (which can be
purchased at most local supply fi rms) are required.
Huck also recommends having available an arbor press
and a vise with soft jaws.

ISASSEMBLY
This procedure is for complete disassembly of the
tool. Disassemble
only
those components necessary
to replace damaged rings, and worn or damaged
components. Always replace O-rings, Back-up rings,
and wipers of disassembled sub-assemblies. Always
use a soft-jaw vise to avoid damaging the tool. For
component identifi cation, see Figure 1.
NOTE
:
Be sure POWERIG is OFF when removing the
nose assembly to clean or replace components. See
applicable Nose Assembly Data Sheet for additional
instructions.
To disassemble the tool:
1. Remove the retaining ring from the split ring. Slide
off sleeve and remove split ring segments. Pull off
the nose assembly anvil and unscrew the nose
collet assembly.
2. Remove the four socket-head screws and
lockwashers from the handle. The handle assembly
and cushion are now separated from the tool.
3. Remove one locator button and unscrew locking
ring using spanner wrench. Remove the second
locator button.
4. Screw the locking ring partially in. Screw two
socket-head screws into the cylinder cap. Use pry
bars under the heads of the screws to gradually pry
the cylinder cap out of the cylinder assembly.
5. Remove the unloading valve.
6. Drain
hydraulic
fl uid from cylinder assembly.
7. Unscrew
the
hoses.
8. Press the piston out of the cylinder assembly. Use
an arbor press if available.
9. Unscrew the ejector cartridge assembly using a
7/16” socket wrench. Slide the ejector out of the
cartridge assembly. Unscrew the retaining screw
from cartridge assembly using 3/16” allen wrench.
10. Remove the retaining ring.
11. Press the adapter out of the cylinder assembly.
12. Use a small dull-pointed rod to remove the O-rings
and Back-up rings from all components.
NOTE
:
Disassemble control trigger systems only
when necessary to rewire or replace the switch/
trigger.
The tool has been properly disassembled. Store all
re-usable
parts (screws and disassembled components)
in a clean, dry area.
WARNING: Disconnect the tool’s control
trigger system from the POWERIG
®
Hydraulic Unit before disconnecting the
hydraulic hoses from it. If not disconnected
in this order, serious personal injury may
occur.
