19. Set the housing cover on the gearbox. Turn in two
jacking screws (1) and four attaching cap screws (2).
Adjust the screws as required so the cover is secured
to but not touching the gearbox.
20. Remove the snap ring (1) and one shim (2) from each
clutch pack bearing assembly. Label each shim re-
moved noting its location. Install the snap rings back
into their respective grooves.
Remove the jacking screws from the cover. Tighten
the attaching cap screws to 45-50 N·m (33-37 ft.
lbs.).
21. Turn the unloading shaft several revolutions to seat
the bearings.
Set up a magnetic base dial indicator as shown on
the unloading shaft. Measure the endplay by pulling
up on the shaft and noting the amount of needle de-
flection. Measure the thickness of the shim removed
from the unloading shaft. Using the formula pro-
vided, calculate the preload on the bearings.
