Rear Final Drive Ring Gear and Pinion Shaft, Adjusting


Rear final drive ring gear and pinion shaft, adjusting
General notes
Careful adjustment of the ring gear and pinion shaft is essential to ensure that the final drive gives long service and runs silently. During manufacture the ring gear and pinion shaft are matched and checked on testing machines to ensure correct mesh pattern and silent running. The position for quietest running is obtained by moving the pinion shaft axially and, at the same time, maintaining the backlash within the specified tolerances.

The deviation "r" from the master gauge "Ro" is marked on the ring gear. Only replace the gear set (ring gear and pinion shaft) together.
