Differential Pinion Shaft and Differential Pinion
1. Draw out the differential pinion shaft 2 (5), and take out the
differential pinion (3) and differential pinion washer (4).
2. Draw out the differential pinion shaft (1), and take out the
differential pinion (2) and differential pinion washer.
NOTE
• Arrange the parts to know their original position.
(When reassembling)
• Check the differential pinions (2) and (3), and pinion shaft (1)
and (5) for excessive wear. If these parts and damaged or
excessively worn, replace their parts they are in mesh with, or
they sliding on.
