10. BEARINGS
Clean bearings using an approved bearing cleaning solvent, or other non-flammable industrial
solvent. Inspect the bearings, replacing them if they are noisy or rough when rotated, or if there
are signs of wear or pitting in the bearing raceways.
WARNING: Under no condition should a combustible solvent such as gasoline be used to clean bearings
or any other part of the pump. The use of such solvents could lead to fire or explosion. Failure to follow
all instructions may result in serious injury, death, or property damage.
11. SHAFT SEALS
Replace.
12. GASKETS AND "O"-RINGS
Replace all gaskets and "0" -rings.
C. ASSEMBLY:
Pump and frame parts are reassembled in the reverse order of dismantling, with special notes as outlined
below. Follow all installation precautions covered in this manual.

1. Frame:

a. Assemble oil slinger (5-485-0) in groove on shaft (5-007-1). For F4Hl frame only, wrap one clamp
strap (5-935-0) around either side of hub, pull tight with pliers, bend back and secure with tabs, and
cut off excess material. Place retaining ring (5-225-4) for F4Hl frame or snap ring (5-915-4) for
F4G 1 and F4J1 on the outboard end of the pump shaft. The flat side of the snap ring faces toward
the coupling end of the shaft. These parts are placed on the shaft to be used in a later assembly step.
b. Assemble the appropriate ball bearings at each end of the shaft. If an arbor press is not available,
the bearings may be heated and quickly slipped on the shaft.
Heat the bearings to 115°C using a clean oil bath or a dry oven.
WARNING: Use insulated gloves when handling hot bearings. Failure to follow all instructions may
result in serious injury, death, or property damage.
The outboard bearing for F4Hl frame consist of two angular contact ball bearings. These bearings
must be installed "back-to-back" (wide shoulder of outer race contacting as shown on Assembly
Section).
Be sure the bearings press firmly against shaft shoulders.
c. Install the bearing lock washer (5-517-9) on the coupling end of the shaft, with the locking tabs
facing away from the bearing. There is a tab on ID. of the lock washer. This tab must fit into the
groove in the pump shaft.
d. Install the bearing locknut (5-516-4) with the beveled edge facing the bearing.
Tighten the locknut using either a spanner wrench or a drift pin and hammer. Tapping the spanner
wrench with a hammer will insure the nut is tight. Be sure the nut comes to rest in a position where
a slot on the nut lines up with a tab on the lockwasher. Bend one of the lock washer tabs into a
matching slot on
the bearing locknut.
e. Press outboard bearing seal (5-177-4) into outboard bearing housing (5-025-4). The bearing seal
