ADJUSTMENT
Selection of main shaft rear plate
Measure the protrusion amount (A) of bearing from transmission main case surface, and select a suitable plate in the following table.
Note. Before measuring, tap the end of main shaft with a plastic hammer lightly in order to make the clearance zero between the main case surface and moving flange of bearing.

- Hypoid gear set match mark/No.: The number (A) on top of the drive pinion, and the number on the hypoid driven gear are set numbers for the two gears. Use a pair having the same numbers. The figure (B) below shows a number for shim adjustment. If no number is shown, the value is zero.
- Place the drive pinion shaft assembly on transmission main case RH without shim and tighten the bearing mounting bolts.
