11. ADJUSTMENTS
a. PRELOADING OF DIFFERENTIAL CASE BEARING
The Ring Gear (Crown Gear) and spline shaft are serviced
in matched set and should only be fitted after
preloading.
In order to ensure quiet operation and long life of ring
gear and spline shaft set the following assembly and
adjustment procedure should be rightly followed.
• Check the spline shaft and ring gear are a
matched set. (Number)
• Preload the differential case bearings.
1) Assemble the differential case and carrier bearings
with left and right shims same as before
dismantling. Tighten with specified torque and
check the preload as follows.
2) Loop both ends of a piece of string and slip on
loop round the differential case opening.
Then Wind the string around the differential
housing. Secure a spring balance into the free
end (as shown in figure) and pull.
NOTE: 1. Pull to keep the assembly revolving at
constant speed which should be between
4.4 - 6.6 lbs.
2. Preloading the differential case and spline
shaft should be done before assembling
of spline shaft.
3. Add or remove shims between the right
hand bearing carrier and Transmission Case
until the above figure is obtained.
4. Once the correct preload has been
obtained, it will only be necessary to
transfer shims from one bearing carrier to
another to obtain correct backlash between
ring gear and spline shaft teeth.
5. After Preloading, remove differential case
assembly with shims and fit after
preloading the spline shaft.
