Recommended Sequence for Adjusting Gear Set
Recommended Sequence for Adjusting Gear Set
If drive pinion and gear ring have to be adjusted, the following sequence is recommended for maximum efficiency:
‹› Determine shim "S3" so that the dimension from center of ring gear to facing drive of drive pinion corresponds to the installation dimension
determined during production.
‹› Determine shim "S4" for double angular contact ball bearing preload.
‹› Total shim thickness "Stotal" Determine (S 1 plus S2) for specified preload of tapered roller bearing/differential.
‹› Total shim thickness "Stotal" Distribute (S1 plus S2) so that the specified torsional backlash is present between ring gear and drive pinion.
