8. Remove inner race of roller bearing from the
housing shaft.
NOTE: This race was Loctited and pressed
in place, and a puller will be required to
remove it.
NOTE: Make sure the center of the housing
is supported and not the outer drum of the
housing.
Assembly Procedure: Using New
Bearings and Seal
1. Press bushings into hub side opposite flange.
NOTE: It is important to press bushings in
straight.
The bushings should also be centered in the
hub socket leaving relatively equal amounts
of bushing sticking out of the hub on each
side.
A suggested simple tool for pressing in
bushing to hub is a 1/4 in. screw x 3 in. or 4 in.
long and 1/4 in. nut. Thread nut onto screw
approximately 3/4 to 1 in.
Figure 75: Bushing Insertion
Insert threaded end of screw into bushing.
Lubricate bushing by dipping in clean water
only. Then press into place.
*DO NOT USE SOAP OR OIL TO
LUBRICATE BUSHING PRIOR TO
ASSEMBLY.
2. Remove the inner race from the roller bearing,
apply a small amount of Loctite #270 to race
I.D. and press onto the housing shaft, seating
against the step.
3. Apply Loctite #270 to O.D. of oil seal, then
press seal in end of hub opposite the flange to
a depth of approximately 1/16 in. below the
surface.
4. Apply a small amount of Loctite #270 to O.D.
of roller bearing and press into hub I.D. from
the flange end until seated against the step in
bore.
5. Slip large and small spacer into hub I.D.
seating against the roller bearing.
6. Apply Mobile #28 grease to roller bearing and
fill cavity between large and small spacers. A
small amount of grease should also be applied
to the seal lip and space between the seal and
roller bearing.
7. Pack ball bearing with Mobile #28 grease.
8. Apply a small amount of Loctite #270 to O.D.
of ball bearing and press into hub until seated
against spacer. Wipe excess Loctite from hub.
9. Install retaining ring.
10. Position shoes in a circle on flat surface and
install springs on shoes.
11. Position shoes on the hub.
12. Install 1/4-28x1-3/4 screws through links,
then external tooth 1/4 lockwasher. Then slide
through bushings in shoes and hub.
13. Install remaining lockwashers then links and
1/4-28 locknuts, torquing them to
110 ± 5 in. lbs (12.5 ± 6 N•m)
NOTE: Shoes MUST be held tightly against
hub while nuts are tightened.
CAUTION: During all bearing assembly,
care must be taken to prevent Loctite from
entering bearing.
