3.9.1 Re-Shimming the Backlash
NOTE : This step is only necessary when adjusting for
incorrect backlash.
c Remove the bearing caps.
c Remove the differential as before.
c To decrease the amount of backlash, reduce the shim thickness ‘D’
(Fig.10.) and increase the shim thickness ‘E’ (Fig.12.) by the same
amount. Reverse this step to increase the backlash.
c Remount the differential as before.
c Release spreader tension (if applicable).
c Check backlash again as before.
3.10 Setting Up the Bulkhead Fitting
c Apply thread sealant to the threads of the bulkhead body.
c Screw the bulkhead body into the tapped hole, and tighten.
c Wipe the area clean of any excess thread sealant (inside and
outside of the housing).
c Pre-bend the seal housing tube so that it roughly resembles the
finished shape and has a tight bend in the very end where it enters
the bulkhead fitting. Refer to Figure 17.
