g. Apply sealer to the stop bolt threads, but not to the
threads at the end of the bolt (approximately 0.20
in.). Install the stop bolt into the shifter.
BEARING ADJUSTMENT
Perform the following procedure if the following com-
ponents have been replaced: input shaft, input shaft bear-
ings, output shaft, thrust washers and output shaft
bearings. This procedure determines the thickness of
shims that must be installed so the tapered roller bearings
properly contact the bearing outer races.
and
1. Install the input shaft, intermediate shaft and output
shafts as described in the Reassembly section.
2. Position the transmission case so the open end is up
and no pressure is being applied to the splined end of the
output shaft.
3. Install the outer bearing races on the input and output
shaft tapered bearings.
4. Measure the distance (A,
Figure 30) in millimeters
the mounting flange mating surface on the case to
the top of each bearing race. Record the measurements.
5. Measure the distance (B, Figure 31) from the mount-
ing flange mating surface to the bottom of the bearing race
bore for both the input and output shaft bearings.
6. Subtract the A measurement from the B measurement
for each shaft.
7. From the result obtained in Step 6, subtract 0.0-0.05
mm. This result equals the thickness of the
that
must be installed in the bearing bores in the mounting
flange.
8. Install the in the bearing bores in the mounting
flange, then press the bearing outer races into the mount-
ing flange on top of the shims. Make sure the races are
bottomed.

NOTE
The following procedure for adjusting the
input shaft bearings is similar to the proce-
dure for the
transmis-
sions, but only use the in Figure 30
and Figure 31 that pertain to the input
shaft.
