Refer to Troubleshooting (→ page 12) to
determine if outlet check assembly (6)
is cause of failure
Pump will not build up sufficient
lubricant pressure if outlet check
assembly (6) is fouled (→ Fig. IPB 2,
page 16 and Fig. IPB 3, page 17) Foreign
material may lodge beneath steel
ball (40) or between pump check disc
assembly (38) and ball check
seat (39) of outlet check bushing (37)
Sealing surfaces of seat must form a
perfect seal Clean parts or replace if
pitted, worn or scored
Turn off and disconnect hydraulic
1
and electric power supply to bare
pump assembly (10)
2 Standard tools required are bench
mounted vice, set of open end
wrenches ranging from
7 / to 1 1 / in, large 24 in (600 mm)
16 2
adjustable wrench and smaller
10 in (254 mm) adjustable wrench
3 Remove hose assembly (7) and

4 Remove outlet check assembly (6)
and adapter (5) by loosening from
connected elbow (3)
5 Remove adapter (5) from outlet
check assembly (6)
6 Remove outlet connector (42) from

Reverse above procedure to
reassemble Torque check assembly to
100 ft-lbf (135 Nm)
Vent valve service
Refer to Troubleshooting (→ page 12) to
determine if vent valve is cause of
failure (→ Fig. IPB 1, page 15; Fig. IPB 2,
page 16; and Fig. IPB 4, page 17)
1 Turn off and disconnect hydraulic
and electric power supply to pump
assembly
2 Loosen grease vent hose
assembly (8), grease supply hose
assembly (7), hydraulic vent hose

in assembly
2 Tighten valve seat (47) into valve
body (49) using 25 ft-lbf (34 Nm)
Tighten cylinder (43) onto valve
body (49) using 100 ft-lbf (135 Nm)
