and the top of the fitting to enable ease of installation of the packing retainer (13).
8. Place the tapered packing retainer tool (PN 70712), stepped part, into the hole in the packing retainer
(13). Place grease on sides of the tool.
9. Slide the packing retainer (13) onto the packing retainer tool (PN 70712) and down into the groove of the
inlet check valve fitting (12).
10. Remove the packing retainer tool (PN 70712) and wipe grease from the tool.
11. Grease both sides of the O-ring (14) and install into the groove on the inlet check valve fitting (12).
12. Use the stepped part of the packing retainer tool (PN 70712) on the check valve seat (15) to install into
the recessed end of the inlet check valve fitting (12). The check valve seat (15) must seat flat. If needed,
tap the tool very lightly to seat, but make sure no damage occurs to the inlet check valve fitting (12).
13. If required, tap the round dowel (25) into the hole on the threaded shaft of the piston ring retainer (24).
Leave extra material protruding from both sides of the shaft. Trim the round dowel (25), using cutters, to
the top of threads on both sides. Thread the piston ring retainer (24) into the piston (18), two or three
turns, to form threads on the round dowel (25). Remove the piston ring retainer (24) from the piston (18).
14. Grease the inside wall of the end cap (19) where the inlet check valve fitting (12), sub-assembly, O-ring,
and back-up ring will touch.
15. Place the spring (9) and check valve (10) into the end cap (19).
16. Thread the “AN” side of the inlet check valve fitting (12), sub-assembly into the fitting holder tool (PN
70710). Now place the sub-assembly into the check valve fitting tool (PN 70709) so the flat side of item
15 goes through the beveled side of the tool.
17. Slide item 12 back and forth in the tool a few times to align the O-ring and backup ring. Remove the
sub-assembly from the check valve fitting tool (PN 70709) and unthread from the fitting holder tool (PN
70710). Thread item 12 sub-assembly into the end cap (19), where the spring (9) and check valve (10)
were previously installed. Tighten using a 5/8” wrench.
Reassembly of Rings and Seals:
Note
Clean all parts with solvent and use an air hose to remove any dust particles from all mechanical parts, except
screws and washers. Wipe the bores of the intensifier housing with a clean cloth before installing the piston. Replace
all damaged parts with new ones.
1. Smear a medium amount of grease in the O-ring cavity on piston (18). Grease both sides of the two
back-up rings (20) and the O-ring (21). Install into the groove on piston (18).
Important

The split of each backup ring (20), must be 180
o
from each other with the ends properly overlapping.
2. Lightly coat the edges of backup rings (20) and the O-ring (21) with oil lubricant (PN 60944).
3. Lightly coat both inside diameters of the housing (17) with oil lubricant.
4. Place grease on the piston ring retainer (24) where the piston rings (22) seat.
5. Place grease on both sides of the three piston rings (22) and install the three piston rings (beveled sides
aligned) onto the piston ring retainer (24).
6. Slide the piston (18) into the housing (17), being careful not to damage wall areas. Slide until the smaller
diameter of the piston (18) is exposed from the side of housing (17).
7. Thread item 24 with the three piston rings (22) into the piston (18) approximately four turns.
8. Stand housing 17 on end, with the piston ring retainer (24) facing upward. Push the piston ring retainer to
verify it will fully go into the housing. The top of the piston ring retainer (24) must be slightly below the
surface of housing (17).
9. Place the housing (17) on its side. Place a 3/16" hex key in the piston ring retainer (24) and a 1/4" hex
key in the piston (18). Rotate the 1/4" hex key to tighten.
10. Remove the 3/16" hex key and verify the piston (18) will rotate. If the piston rotates, remove the 1/4" hex
key. If it does not rotate, loosen the piston slightly.
11. Grease both sides of the O-ring (4) and end cap (3) O-ring groove. Install the O-ring (4) into the groove
of the end cap (3).
