2580 series Hydraulic Installation Tools (HK961)
Disassembly
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 seals, wipers, O-rings, and
Back-up rings of disassembled components. Always use
a soft-jaw vise to avoid damaging the tool.
For component identification, see Figure 3 and the
Assembly Drawings in this manual.
TO DISASSEMBLE THE TOOL:
1. Disconnect the tool’s electric trigger control cord,
and then uncouple the hydraulic hoses.
2. Remove the retaining nut and nose assembly anvil.
Unscrew collet from the piston rod.
3. Unscrew both couplers (nipple & body) from the
hoses, and drain the hoses into a container.
4. Push rearward on the piston until the remaining
hydraulic fluid is drained into a container. Discard
the fluid .
NOTE : Do NOT remove the hydraulic hoses from
the tool unless replacing them. If necessary to
remove the hoses, slide back the plastic shrouds
to access the hose fittings.
5. Model 2580 : Loosen the strain relief grommet.
Loosen the set screw and carefully pry out the
switch with a small screw driver. Loosen the two
wires at rear of the switch and remove it from the
cord. Pull out the cord and remove the grommet.
Disassemble the electrical connector to replace
connector, or to rewire it.
Model A2580 : Unscrew the air trigger assembly.
Loosen the air fitting. Pull out the air trigger hose.
Loosen the air quick disconnect and remove it.
6. Remove the pintail deflector (P/N 123144 ) from the
end cap by simultaneously pulling and twisting.
7. Remove the socket-head screw from the rear gland
and barbed retainer.
8. Insert two 5/16” pins in opposite holes in the rear of
the barbed retainer. Place a bar between the pins,
and use it to unscrew the retainer.
9. Remove the unloading valve from the open cylinder.
10. Place the Spacer (P/N 123112-1 ) over the threaded
end of the piston. Screw the Piston Assembly Tool
(P/N 123111-1 ) onto the piston. (Figure 3) Press or
drive the piston, front gland, and rear gland out of
the cylinder. Place the hose ends in a container to
catch fluid that is forced out by the piston .
11. Use a small, dull pointed “pick” to remove all seals,
wipers, O-rings and Back-up rings from components .
The tool has been properly disassembled. Store all
re-usable parts (screws and disassembled components)
in a clean, dry area.
WARNING: Disconnect the tool control
trigger system from the Powerig
®
before
disconnecting the hydraulic hoses from it.
If not disconnected in this order, serious
personal injury may occur.
