thread retainer (3) over check valve cartridge (4). Allow 24 hours for
thread locking compound to set.
3. Install plugs (11) in cross- drilled passages by applying thread locking
compound to plug threads. Then thread plugs (2 each per hole), with
the second plug acting to lock in the first. Allow 24 hours for thread
locking compound to set.
Install Plunger Button Seals and Retainer Pins in Hydraulic Piston
1.
Install new backup ring (7) and O-ring (8) in each internal groove in
each plunger pocket (2 places).
CAUTION
Failure to install backup ring can result in plunger
being forced out of plunger pocket.
2. Reinstall pins in piston, verifying that each pin moves freely without
excess side play in its cavity.
3. Reinstall band (6) over pins. Repeat this process for the opposite
piston side. With piston on bench, install plunger in each end of
piston, checking snap-in feature of plunger attachment. Use plunger
removal tool to verify that pins retract (release plunger) and close
(retain plunger) in a uniform manner.
Install Hydraulic Piston Assy into Hydraulic Cylinder
NOTE:
Piston seal assembly must be compressed before the piston
assembly will slide into the hydraulic cylinder. A ring compression
tool such as shown in the figure below is recommended.
1. Check that hydraulic cylinder bore is free grit, or contamination, and
that the proximity switches are removed to prevent interference.
Lubricate piston bearing and seal surfaces with FML-2 grease.
Lightly lubricate 2-3 inches of cylinder (15) bore with same grease.
2. Fit or drive piston assembly into ring compression tool (20). Position
compression tool with piston assembly over end of hydraulic cylinder.
Using a plastic- faced hammer so as not to damage piston surfaces,
gently drive the piston assembly into the hydraulic cylinder.
3. Remove seal compression tool, continue driving piston assembly into
hydraulic cylinder until it is between the proximity switch holes.
Continue intensifier re- assembly by installing cylinder heads,
plungers, hydraulic seal cartridges, and HP components.
