The thickness of the spacer shim(s) determines the preload on the tapered roller bearing. The following procedure is used to determine the required shim size and thus ensure that the correct level of bearing preload is obtained.
1 Place the interaxle pinion housing (2) on the inner tapered roller bearing (3) and insert the outer tapered roller bearing (1).

2 Measure and record the dimension "A" between the inside end face of the inside tapered roller bearing and the outer end face of the outside tapered roller bearing.

3 Measure and record the dimension "B" between the shaft shoulder (arrow) and the contact surface of the tapered roller bearing on the drive pinion (5).
4 Calculate dimension "E", thickness of the spacer shim.
Example:
Dimension "A" = 86.6 mm
Dimension "B" = 81.6 mm
Dimension "E" = Dimension "A" Dimension "B" 0.2 mm
Dimension "E" = 86.6 mm 81.6 mm 0.2 mm = 4.8 mm
