Assembly and Installation
70 MAINTENANCE MANUAL
1.Install the capscrews, but not the washers,
that fasten the input shaft bearing cage to
the differential case. Rotate the input shaft in
each direction to verify that the bearings are
correctly installed while you hand-tighten the
capscrews. Do not tighten the capscrews.
2. Use a feeler gauge to measure the gap be-
tween the input shaft bearing cage and the dif-
ferential case. Inspect the gap at four equally-
spaced places on the cage. Figure 5.82.
4. Build a shim pack. Use at least three shims
when you build a shim pack. Always place the
thickest shims in the middle of the shim pack.
5. Remove the capscrews that fasten the input
bearing cage to the differential case.
6. Install the shim pack.
A. Connect a lifting device to the input fork. Lift
the input shaft assembly until there is 0.25-
0.50-inch (6-12 mm) between the bearing
cage and the differential case.
B. Install the shim pack under the input shaft
bearing cage. Verify that the hole pattern of
the shim pack matches the hole pattern of
the differential case. Figure 5.84.
C. Install the capscrews and washers that fasten
the input shaft bearing cage to differential case.
Verify that the capscrews are aligned with the
holes in the shim pack. Tighten the capscrews
so that the threads engage in the holes of the
differential caser.
D. Lower the input shaft assembly so that the
bearing cage and the shim pack are installed
against the differential case. Remove the
liftingdevicefromtheforkorange.
E. Tighten the capscrews to 75-95 lb-ft (100-127
Nm) while rotating the input shaft in each di-
rection to verify that the bearings are correctly
installed.
3. Add up the four measurements and deter-
mine the average gap between the bearing
cage and the differential case. Add 0.005-
inch (0.130 mm) to the average gap mea-
surement to determine the size of the shim
pack between the bearing cage and the dif-
ferential case. Figure 5.83.
