Final Drive Set Sequence For Re-Adjusting

Final drive set sequence for re-adjusting





When ring gear and drive pinion have to be adjusted, in the interests of a rational sequence, keep to the following order:
1.) Determine total shim thickness "Stotal" for "S1" + "S2" (sets pre-load for tapered roller bearings for differential).
2.) Determine total shim thickness "Stotal" for "S3" + "S4" (sets pre-load for tapered roller bearings for drive pinion).
3.) Distribute total shim thickness "Stotal" for "S3" + "S4" so that the distance from center of ring gear to face of drive pinion is the same as distance "R" which was determined during production.
4.) Distribute total shim thickness "Stotal" for "S1" + "S2" so that specified backlash exists between ring gear and drive pinion.
