With Input Shaft Axial Spring Thrust Button
In September 1988,
Spicer added an axial spring and thrust
button between the input and output shafts. The addition of
these parts reduces shaft end play movement by loading the
shafts axially in the direction of the yoke. End play tolerances
are the same for axles with or with out the new spring and
thrust button. However, end play measurement procedure is
different as described below.
Note: As of September 1994, production and service output
shafts for the D461, 521 and 581 models are no longer
produced with a bushing in the end of the shaft. The
shafts can be identified by part number, see Output Shaft
Assembly on page 38 for more information.
Input Shaft Axial Spring
1. Fabricate a U-bracket from 1 in. flat stock (minimum
thickness 0.125") as specified in the illustration.
2. If axle is assembled, first remove input shaft nut, flat
washer and yoke.
3. Build up a 0.045" (0.024 mm) thick shim pack and
place shim pack and bearing cover on power divider
cover.
4. Install the U-bracket on bearing cover, using two
bearing cover capscrews. Install all other cover cap-
screws and torque to 75-85 lbs. ft. (101-115 N•m).
