41. With bearing cups fitted onto cones lower differential case assembly into the carrier.
Take care when meshing gear and pinion not to damage the teeth.
42. Position a dial gauge as shown in Fig. 20.
43. Fit suitable shim packs between the differential bearing caps and carrier on each
side in order to give a reading of .007" on the dial gauge when the gear backlash is
measured. It is important that the pinion is not moved when measuring ring gear
backlash, otherwise false results are obtained. The shim packs should be a
resistance fit.
Shims are available in .003", 005", 010" and .030".
NOTE: When using new bearings rotate differential assembly approximately six
times whilst pressing assembly towards each bearing in turn - this is in order to
settle bearings. Following this adjust shim packs if necessary to give resistance fit
and repeat backlash check.
44. Remove differential assembly together with shim packs. Carefully note to which end
the shim pack relates. Add .003" shim to each pack in order to give bearing preload.
45. Remove one differential bearing cone from case and fit appropriate shim pack to
case trunnion. Refit bearing cone.
46. Repeat above on other differential bearing.
47. Fit carrier stretcher tool to carrier and stretch carrier.
IMPORTANT: DO NOT STRETCH CARRIER MORE THAN .010" - 012" MEASURED
ACROSS STRETCHER HOLES.
