If drive pinion and crown wheel have to be adjusted, it is appropriate to adhere to the following sequence in the interests of rational working:

• ◆ → Determine total shim thickness "Stot" (S1 plus S2) for specified pre-load of differential taper roller bearings.
• ◆ Determine total shim thickness "Stot" (S3 plus S4) for specified pre-load of drive pinion taper roller bearings.
• ◆ Divide up total shim thickness "Stot" (S3 plus S4) such that dimension from centre of crown wheel to end face of drive pinion corresponds to installation dimension "R" determined during production.
• ◆ Divide up total shim thickness "Stot" (S1 plus S2) such that prescribed backlash is attained between crown wheel and drive pinion.
