2580 series Hydraulic Installation Tools (HK961)
This section details the re-assembly of the tool. For
component identification, see Figure 4 and the Assembly
Drawings in this manual.
BEFORE RE-ASSEMBLING THE TOOL:
- Inspect components for scoring, excessive wear, and
damage ; replace as necessary. Clean components in
mineral spirits or other solvent compatible with O-ring
seals. Clean O-ring grooves.
- Replace all O-rings, Quad-rings, and Back-up rings.
See Assembly Drawings for guidance on positioning
these rings. Take care not to damage rings. Use the
rings that are supplied in Spare Parts Service Kit
2580KIT . Smear LUBRIPLATE
®
130-AA or SUPER-O-
LUBE
®
on rings and mating parts to ease assembly.
- Apply Parker Threadmate
®
, Loctite
®
567, or Slic-Tite
®
to male pipe threads per manufacturer’s instructions.
TO RE-ASSEMBLE THE TOOL:
1. Install the GLYD Ring Assembly on the piston as
follows: Place the special O-ring in the groove. Roll
the GLYD ring’s diameter to a diameter smaller than
the piston before placing the GLYD ring on top of
O-ring. Coat the GLYD ring with a suitable lubricant
to ensure it stays in place during piston installation .
2. Taking care not to pinch the inner ring, press the
Polyseal into the front gland housing. Install O-ring
and back-up ring on the front gland assembly.
3. Screw the Piston Assembly Tool onto the piston .
(Figure 4)
NOTE : To keep the Polyseal in the front gland,
push the front wiper housing into front gland.
Hold housing against Polyseal while pressing the
front gland/Polyseal onto the piston.
4. Press with a suitable pressing drift against the back
of the piston. While holding the wiper housing in
place, guide the Polyseal onto the piston .
5. Press the wiper into the groove on the wiper
housing. NOTE: Thread the retaining nut onto the
cylinder to act as stand-off.
6. Lubricate the outer seal of the piston and the
Polyseal.
7. Install the GLYD Ring Insertion Tool into the cylinder
to prevent damage to the GLYD Ring Assembly.
(Figure 4)
8. Carefully drive, or press, the piston into the cylinder.
9. Remove the Piston Assembly Tool and GLYD Ring
Insertion Tool. Install the relief valve into the piston
with four flats toward the rear of the tool.
10. Install the following in the rear gland: O-ring and
back-up ring; Polyseal , spacer, and retaining ring;
press the assembled gland into the cylinder; press
the wiper into the groove in the rear gland.
11. Align the recess in the rear gland with the groove in
the cylinder. Install the locking disc.
12. Screw the barbed retainer into the cylinder until it
bottoms out. Back out the retainer to the first visible
threaded hole in the rear gland. Install and tighten
the locking screw to 35 (+/-3) in.-lbs.
13. If the hydraulic hoses were removed, apply Parker
Threadmate
®
, Loctite
®
567, or Slic-Tite
®
to male pipe
threads per manufacturer’s instructions .
Thread the hydraulic hoses into the handle, and
slide the shrouds over the fittings.
14. Model 2580 : Assemble the electrical cord to the
connector. Screw the strain relief grommet into the
handle. Push the cord through the grommet. Attach
the cord to the trigger switch. Press the switch into
the handle and tighten the setscrew against the
switch. Pull the excess cord down through handle
and strain relief grommet. Tighten the grommet.
Model A2580 : Thread the hose fitting into the
handle. Attach the quick-disconnect to the air-line.
Attach the air-line to the handle’s hose fitting. Screw
the air trigger assembly into the handle’s trigger
fitting and tighten the setscrew against the fitting.
