3. Install needle thrust bearing (8), then bearing race (7) on
shaft (9). Pull shaft partially out of housing. Push all
three parts in housing (10) together (See Figure 4-29).
The bearing race must rotate freely when in position.
4. Visually check seal seats in the mounting flange for
scratches or other marks that might damage the seals
(5). Check for cracks in flange (3) that could cause
leakage.
5. Install exclusion seal (2, Figure 4-24) in flange (3) with
the lips of the seal facing out (see Figure 4-30). Carefully
press the exclusion seal in place.
6. Install shaft pressure seal (5) in flange (3) with lips of
seal face up using a suitable driver. See Figure 4-31.
Carefully press the pressure seal in place.
NOTE: After installing the seal in the flange, examine the
seal condition. If damaged or improperly installed,
replace the seal before continuing with assembly.
7. Install O-ring (6, Figure 4-24) into groove in flange (3).
8. It is recommended to apply a light coat of Loctite Primer
NF in tapped holes of housing (10). Allow the primer to
air dry for at least 1 minute. Do not force dry with air jet;
the primer will blow away.
Use of primer is optional. With primer, Loctite curing time
is approximately 15 minutes. Without the primer the
curing time is approximately 6 hours.
9. Apply 3 or 4 drops of Loctite sealant at the top of the
threads for each of the four holes in the housing (see
Figure 4-31). Do not allow parts with Loctite to come in
contact with any metal parts other than those for
assembly. Wipe off excess Loctite from housing face,
using a non-petroleum base solvent.
Do not apply Loctite to threads more than 15 minutes
before installing screws. If the housing stands for more
than 15 minutes, repeat application. No additional
cleaning or removal of previously applied Loctite is
necessary.
