The thicknesses of the spacer washers determine the friction torque of the tapered roller bearings. The following procedure is used to determine the required shim size and thus ensure that the specified friction torque is obtained.
1 Place the interaxle pinion housing (2) onto the inner tapered roller bearing (3) and insert the outer tapered roller bearing (1).
W33.30-0044-01
2 Measure and record dimension (A) between the inner frontal area of the inner tapered roller bearing and the outer frontal area of outer tapered roller bearing.
W35.30-0005-01
3.1 Measure and record dimension (B) between collar of inner tapered roller bearing (1) and contact surface of spacer tube (6).
For ring gear dia. 300 mm
W33.30-0036-01
3.2 Measure and record dimension (B) between the shaft collar (arrow) and the contact surface of the tapered roller bearing on the drive pinion (5).
For ring gear dia. 233 mm
4 Measure thickness ("E") of spacer washer: Dimension "A" - dimension "B" = dimension "C"
Thickness "E" of the shim must be lesser than dimension "C" by the amount of the value specified in the table.
