FIGURE 24— Installing Front Pinion
Bearing Cup
Front bearing tool J-2531 is used for the
"Hornet" Series; J-2532 for "Wasp" and "Rambler"
Series.
FIGURE 25— Installing Rear Pinion
Bearing Cup
Rear bearing tool J-2533 is used for the
"Hornet" Series; J-5367 "Wasp" and "Rambler"
Series.
CAUTION: Drive the bearing cups
straight into clean bores.
Pinion Depth Adjustment
To compensate for machining tolerances, the
pinion and ring gears are factory tested for tooth
contact and quietness. This test is conducted at
a standard cone setting and varied to obtain
correct tooth contact and quietness.
The amount of this variation is etched on the
rear face of the pinion gear (Fig. 18).
The gear is marked "Plus" or "Minus" the
number of thousandths that the gear varies
above or below standard. Thus "Plus" ( ) means
the pinion gear is closer to the center line of
the axle than standard and the "Minus" (–) means
farther from the center line.
When using a new ring and pinion set or a new
rear bearing, use a new adjusting washer.
Adjusting washers are available in two sizes,
.105" and .125", plus .003", .005", and .010"
shims to obtain various thickness combinations.
Various methods of determining the correct
thickness of adjusting washer may be used.
Method No. 1
Rear axle drive pinion gauge J-5223-A with side
bearing bore adapters to fit each axle may be
used to adjust the pinion depth (Fig. 26).
FIGURE 26— Rear Axle Pinion Setting Gage
Place the rear pinion bearing cone in the
bearing cup. Press the cone and revolve it to
"set" the rollers.
Bolt the gauge plate J-6099-1 over the
bearing cone so it does not touch the housing
at any point. The bolt runs down through the
bearing and is secured at the pinion end by a
cross piece and thumb screw.
Be sure the differential bearing bores in
housing are clean. Install the arbor with the
adapters squarely seated in the side bearing
bores in the housing. Install differential
bearing caps and tighten bolts finger tight.
The adapters slide on and off the arbor. Use
adapters J-5223-5 for the "Hornet" Series and
adapters J-5223-17 for the "Wasp" and "Rambler"
Series.
The gauge block is held in place against the
spacer by the clamp. The gauge plunger pad can
be moved to contact the gauge arbor by loosening
the thumb screw in the end of the gauge block.
After contact is made, tighten the thumb screw.
