Hi Everyone
To follow on from my question above, I have now re-assembled the diff and torque tube in order to check the mesh pattern.
As part of the rebuild I have replaced the pinion thrust bearings, diff carrier bearings and the original pinion shim thickness (15 thou in my case) and I've set the backlash to within spec (1.6mm just over 1/16" at the tightest spot). I have also pre-loaded the adjusters as per Woodrow.
The pictures below show the results on the drive side of the teeth (the overrun pattern is more central and oval in shape). I have read in the service journal that the mesh needs to be towards the bottom of the teeth. I believe this is to allow for the pinion to travel up the teeth slightly during normal operation.
My question is does this mesh pattern look ok/useable taking into account 90 years of wear, or is it likely to destroy itself as soon as I go down the road
?
Thanks
Matthew
