| Recommended sequence for adjusting gear set |
| The following work sequence is recommended to save time when the crown wheel and pinion shaft have to be adjusted: |
| t
| Determine total shim thickness “Stotal” (S1 plus S2) to obtain specified preload on differential tapered roller bearings. |
| t
| Determine shim thickness “S3” required for specified position of pinion shaft. |
| t
| Distribute total shim thickness “Stotal” (S1 plus S2) so that the specified backlash between crown wheel and pinion shaft is achieved. |
| The object of the adjustment is to reproduce the setting for quietest possible running, as obtained on the test machine in production. For good results, maximum care and cleanliness are very important when performing repairs and taking measurements. |
