12 PIN7000/PIN7010 Operation and Maintenance Manual
Disassembly Rings and Seals:
1. Remove intensifier assembly from PIN7000/PIN7010 per Section 3.2.2 on page 7.
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 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:
NOTES:
Clean all parts with solvent and use shop 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 spring (9) and check valve (10) into spring housing (8).
1.1.Press check valve seat (11) into spring housing (8), using large diameter end of check valve seat tool (PN
70711). Be sure check valve seat (11) is seated. Coat grease in bottom groove marks, in hole of end cap
(19) where fitting item (16) goes.
NOTE: The larger of the 2 seats belongs to the outlet check valve. Very important not to get grease in counter-sunk hole
located at center of groove marks.
1.2. Place grease on bottom of items (11/8) sub-assembly.
NOTE: Very important not to get grease on item 10.
1.3. Slide (11/8) sub-assembly into end cap (19), until properly seated on bottom. Thread high pressure
tube fitting (16) into end cap (19) and tighten using a 5/8” wrench.
2. For the inlet valve, perform the following steps:
2.1. Thread AN side of inlet check valve fitting (12) into fitting holder tool (PN 70710).
2.2. Place a small amount of grease (PN 55593) on inlet check valve fitting (12) between groove area and top
of fitting to enable ease of installation of packing retainer (13).
2.3. Place tapered Packing Retainer Tool (PN 70712), stepped part, into hole in packing retainer (13). Place
grease on sides of tool.
2.4. Slide packing retainer (13) onto packing retainer tool (PN 70712) and down into groove of inlet check
valve fitting (12).
2.5. Remove packing retainer tool (PN 70712) and wipe the grease from tool.
2.6. Grease both sides of O-ring (14) and install into groove on inlet check valve fitting (12).
2.7. Use stepped part of packing retainer tool (PN 70712) on check valve seat (15) to install into recessed end
of inlet check valve fitting (12). Check valve seat (15) must seat flat. If needed, tap tool very lightly to
seat, but make sure no damage occurs to inlet check valve fitting (12).
2.8. If required, tap round dowel (25) into hole on threaded shaft of piston ring retainer (24). Leave extra
material protruding from both sides of shaft. Trim round dowel (25), using cutters, to top of threads on
both sides. Thread piston ring retainer (24) into piston (18), two or three turns, to form threads on round
dowel (25). Remove piston ring retainer (24) from piston (18).
2.9. Grease inside wall of end cap (19) where inlet check valve fitting (12), sub-assembly, O-ring & backup
ring will touch.
2.10.Place spring (9) and check valve (10) into end cap (19).
