Determine shim thickness on drive pinion

Compensating washers thickness
FAG-3 (ILoctite) chemical joint application on the contact surfaces must only occur after adjusting the contact marks of crown gear teeth with the pinion.
The thickness of the compensation washer pack will determine the ideal contact marks for the crown gear teeth.
If the same crown gear and pinion are to be installed, the same set of compensation washers previously installed is also to be used.
If different crown gear and pinion are to be installed, consider the values engraved on the new and the used pinion head; the difference between both must be added or subtracted from the thickness of the compensation washer pack that was originally installed.

Determine shim thickness on drive pinion

1

Measure and write down the thickness of the original compensation washer pack.



2

Note the number engraved on the original pinion head. If the number is positive (+), subtract this value from the thickness of the original washer pack. If negative (-), add the value.



3

Register the value obtained in item 2.



4

Note the measurement engraved on the new pinion. If the value is positive (+), add this to result obtained in item 2; if it is negative (-), deduct.



5

The final result obtained determines the thickness of the new compensation washer pack..  . 



Values engraved on the pinion head are given in hundredth of 1 millimeter.
Example:
Original pack = 0.90
Original pinion = + 0.05
Calculation: 0.90 - 0.05 = 0.85
New pinion = - 0.13
Calculation: 0.85 - 0.13 = 0.72 (new shim pack measurement)
