Recommended Sequence For Adjusting Gear Set

Recommended sequence for adjusting gear set
When the ring gear and pinion shaft have to be adjusted, in the interests of a rational sequence, keep to the following order:
^ Determine total shim thickness"S_total" (S3) for the specified preload on pinion shaft tapered roller bearings.
^ Determine total shim thickness "S_total" (S1 plus S2) to give specified preload on differential tapered roller bearings.
^ Distribute total shim thickness "S_total" (S1 plus S2) so that the specified backlash between ring gear and pinion shaft is achieved.

The aim of this adjustment is to re-attain the position which offers the quietest running as calculated on the test machine during production. The utmost care and cleanliness during all assembly work and measurements is essential to achieve a good result.
