| Adjusting pinion shaft and crown wheel |
Note | t
| Careful adjustment of the crown wheel and pinion shaft is essential to ensure that the final drive gives long service and runs silently. During manufacture the crown wheel 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, while at the same time maintaining the backlash within the specified tolerance. |
| t
| The deviation, or tolerance “r”, which is related to the master gauge “Ro”, is marked on the outer circumference of the crown wheel. |
| t
| Only renew gear set (crown wheel and pinion shaft) together! |
