I'm currently in the process of rebuilding my engines and gearboxes (see my signature for the project blog) and came by this situation yesterday.
I measured the diff output shafts, diff cage bushes and crown wheel bushes to see if I have to get new bushes fitted.
The measurements read:
- diff output shafts: 26.13 .. 26.15 mm (1.029 .. 1.030")
- crown wheel bushes: 26.22 .. 26.24 mm (1.032 .. 1.033")
- diff cage bushes: 26.30 .. 26.32 mm (1.035 .. 1.036")
This means a maximum clearance of 0.19 mm (0.007") which looks ok for me. Which is a bit strange is the fact that, while the measurements on all crown wheel bushes are within a very small range as are the measurements of the diff cage bushes, they are actually different.
Have you come by this situation and what is your opinion on the clearances?
