16. Install a new O-ring on the hydraulic motor pilot for
an SAE C flange motor, or in the motor adapter for
the SAE D flange motor. Install the hydraulic motor
onto the motor adapter engaging the motor splines
with the overrunning clutch inner race. Install the four
capscrews and lockwashers which secure the motor
to the motor adapter. Connect the brake release hose
to the brake release port on the hoist drive.
17. Fill bearing cavity through the grease fitting at the
drum support end with a NLGI #2 EP grease with a
Lithium complex base that meets or exceeds NLGI
GC or GC-LB specifications.
DRUM SUPPORT END BRACKET
SERVICE
If the hoist disassembly procedure has been followed to
this point, remove the C-clamps installed in step 4. If only
this end of the hoist is being serviced, support the hoist on
the motor end bracket and remove the 12 capscrews and
lockwashers securing the end of both tie plates (Item 1),
to the drum support end bracket (Item 2). Loosen the 12
capscrews on the other end of both tie plates just enough
to allow the tie plates to be pried free of the dowel pins in
the drum support end bracket.
The hoist end plate weighs 315 pounds (143 kg). En-
sure the hoist and rigging are rated for this weight. Us-
ing a hoist or rigging with insufficient rating may result
in personal injury or death.
1. Lift the support end bracket from the drum.
NOTE: If the hoist disassembly procedure was fol-
lowed and the drum is on top of the end bracket, lift the
drum from the support end bracket.
2. The outer hub (Item 1) is in the end bracket, and the
drum support (Item 3) is in the drum. Remove the re-
taining ring (Item 2) and the seal carrier and seal (Items
6 and 7). Remove and discard O-ring (Item 9). Re-
move the seal from the seal carrier and discard.
Thoroughly clean all parts and inspect for damage and
wear. The bearing rollers should not exhibit any irregulari-
ties. If the rollers show any sign of spalling, corrosion, dis-
coloration, material displacement or abnormal wear, the
bearing should be replaced.
Apply a nonhardening sealant to the outside diameter of
a new seal. Install the seal into the seal carrier as shown
above. Install a new O-ring against the outer race of the
bearing and install the seal carrier into the bearing carrier/
end cap. Install a new retaining ring into the groove in
the end cap. Liberally pack the bearing and end cap with
grease. The end bracket can now be placed on the drum,
or the drum placed on the end bracket, depending on your
method of assembly.
