The compensation washers thickness determines the moment of friction (pre-load) of the pinion tapered roller bearings.
1 Put the tapered roller bearings (1) and (3) in the gearbox for the rear axle (2), in their respective housings.
B35.30-0132-01
2 Measure the distance “A” between both tracks and write down the measurement.
B35.30-0049-01
With the rear ring of 300 mm
3.1 Measure the distance “B” between the tapered roller bearing face (1) and the bushing external face (6).
B35.30-0084-01
With the rear ring of 233 mm
3.2 Measure the distance “B” between the shaft collar indicated by the arrow and the pinion bearing thrust surface (5).
4 Calculate the measurement “E”, compensation washers thickness for the ring gears of 233 mm and 300 mm. Measurements available of the washer 4.1; 4.2 and 4.3 to 5.10 mm with increments of 0.05 mm.
The measurement “E” is resulting from the operation (A-B) and provides an adjustment without play, without moment of friction.
To obtain the moment of friction prescribed for the pinion bearings, select a compensation washer 0.10 mm smaller than the thickness obtained in the operation (A-B).
