Fig. 69—Tightening Coupling Screw
age the babbitt bushings when installing rotor,
insert rotor and shaft assembly, with coupling
end first, into pump body. Insert outer rotor
into pump body. Coat the "0" seal ring with
Lubriplate and position on pump body. Place
cover in position on pump body and install the
five attaching bolts and lockwashers. Tighten
to 35 foot-pounds torque.
Tap coupling flange on pump shaft until it
bottoms and install special square washer,
screw, and lockwasher. Using tool to hold
coupling, as shown in Figure 69, tighten screw
to 12 foot-pounds torque. To attach reservoir
to pump, coat the "0" seal rings with Lubriplate.
Install the two large and two small "0" rings on
the reservoir mounting surface of pump. Place
reservoir on pump, install filter standpipe stud
and two reservoir to pump attaching screws.
Tighten screws to 17 foot-pounds torque. Install
filter element and tighten filter retaining screw
assembly until it seats on the screw shoulder.
Install cover to keep dirt out of pump until after
it has been installed on generator.

Refer to Front Wheel Alignment procedures in
this section.
SERVICE DIAGNOSIS
27. LEAKAGE THROUGH VENT IN UPPER
HOUSING
Signs of oil at the upper housing vent hole does
not necessarily indicate that an internal seal is
causing the leaking. Make the following checks
before disassembly of the unit:
Overfilling of the upper housing. If an upper
housing has recently been refilled, oil may seep
out the vent hole due to expansion after the gear
has been operated.
If a unit has recently been installed, it is pos-
sible that in handling some oil may have become
trapped in the vent passage and may drain as
the gear is operated.
If doubt exists as to whether internal seal
leakage is causing a leak at the vent, or whether
it is caused by one of the above conditions, make
the following check: Insert a pipe cleaner, or a
similar absorbent object, into the vent to absorb
any oil that may have been trapped in the vent
passage. Start the engine and rotate the steering
wheel from right to left, holding it against
the wheel stop for a short time. Do not exceed
1400 engine r.p.m. or hold the wheels against
the stops longer than 15 seconds.
If the oil does not come out the vent during
this test, there is no need for further corrective
work. There is, however, a rare possibility that
the neoprene plug could have been lost from the
vent package inside the housing and caused the
loss of all the oil in the upper housing.
NOTE
If it is not necessary to add oil to the reservoir
betiveen checking periods of 1,000 miles, it is
a good indication that there is not seal leakage,
but a normal amount of seepage brought about
by expansion of the oil during gear operation.
