Good job so far - How do you plan to shim the bearings back up ? The pinion shaft bearing and input shaft bearings have shims to set clamping force on the outer races and set the pinion shaft height ?
There is a tool to do this but they have to be removed.
Also you are now swapping a pinion shaft into another gearbox with a different differential.. ? They are matched when new and have matching numbers with installation heights and backlash figures.
The differentials all need pre-loading and then the backlash setting.
This really is a specialised job as quite a lot of specialist tools are required in order to set the gearbox up properly.
I have read about the different shims for this, and seen photos of cut-away cases being used so that the clearance can be measured with the case fitted. What I haven't found yet though is the required clearance figures. In fact there generally seems to be very little information on rebuilding these gearboxes.
