Determining thickness of shim "S4" when renewing output flange
Determining thickness of shim "S4" when renewing output flange
This adjustment is only necessary when renewing the output flange. It serves to re-set the required preload of the tapered roller bearings for the shaft bevel gear.
   
–  Measure length of shaft on removed output flange and new output flange and calculate the difference.
  N39-0799
Example:  
Removed output flange43.50 mm
New output flange43.30 mm
Difference0.20 mm

If the new output flange is longer: Install a thinner shim for S4 (thickness reduced by the difference calculated above).
If the removed output flange is longer: Install a thicker shim for S4 (thickness increased by the difference calculated above).
–  Refer to Parts catalogue for correct shim(s).
