Disassembly Rings and Seals:
1. Remove the intensifier assembly from PIN8000/PIN8010 per Section 4.2.2 on page 6.
2. Remove the 10 cap screws (1) and washers (2) from the end cap which has the single elbow fitting (23).
3. Remove the end cap (3) and O-ring (4).
4. Remove the piston (18).
5. Remove the small piston retainer (24) and three piston rings (22).
6. Remove the large piston O-ring (21) and two packing retainers (20).
Disassembly of Check Valves:
1. Remove the inlet check valve fitting (12) and outlet (16) port.
2. For the outlet valve, remove, in order, the spring housing (8), spring (9), poppet (10) and seat (11).
3. For the inlet valve remove, in order, the seat (15), poppet (10) and spring (9).
Reassembly of Check Valves:
Note
Clean all parts with solvent and use an air hose to remove any dust particles from all mechanical parts, except
screws and washers. Replace all damaged parts with new ones.
For ease of assembly and to prevent damage to parts, it is recommended to use the following tools during assembly:
• check valve seat tool (PN 70711)
• fitting holder tool (PN 70710)
• tapered packing retainer tool (PN 70712),
• check valve fitting tool (PN 70709)
For the outlet valve:
1. Assemble the spring (9) and check valve (10) into the spring housing (8).
2. Press the check valve seat (11) into the spring housing (8) using the large diameter end of the check valve
seat tool (PN 70711). Be sure the check valve seat (11) is seated. Coat grease in the bottom groove marks
and in the hole of the end cap (19) where fitting item 16 goes.
Note
The larger of the two seats belongs to the outlet check valve. It is very important not to get grease in the
counter-sunk hole located at the center of groove marks.
3. Place grease on the bottom of items (11/8) sub-assembly.
Important

Take care to not get grease on item 10.
4. Slide the (11/8) sub-assembly into the end cap (19) until it is properly seated on the bottom. Thread the
high pressure tube fitting (16) into the end cap (19) and tighten using a 5/8” wrench.
5. For the inlet valve, perform the following steps:
6. Thread the “AN” side of the inlet check valve fitting (12) into the fitting holder tool (PN 70710).
7. Place a small amount of grease (PN 55593) on the inlet check valve fitting (12) between the groove area
