34. Measure distance Y according to the picture above. Y is
the distance from the bevel pinion shaft bearing surface to
the upper surface of the rod ETV 893 451 (e.g. 99,10 mm).
Place the vernier caliper through the groove in the rod.
34a. The sought measurement B (distance between the
bevel pinion shaft bearing surface to the middle of the dif-
ferential bearing locations) can be calculated as follows:
B = Y --- d + D / 2 , e . g . :
B= 99,10 mm---25 mm + 45 mm = 119,10 mm
116,10
35. Read measurement V (e.g. 116,10) at the end of the
bevel pinion shaft.
Thickness of spacer ring between the bevel pinion and the
bearing can be calculated as follows:
S = B --- V, e . g .
S=119,10 mm---116,10 mm = 3.00 mm
Choice a correct spacer ring S. Available from 2,5 mm to
3,4 mm: (with increments of 0,1 mm).
36. Fit the correct spacer ring S (chamfered side to the
bevel pinion side) and the bearing. When needed, warm
the bearing to +80˚C before fitting.
G. Adjusting pre---load of bevel pinion
shaft bearings
37. Fit the thrust washer on the shaft, new compression
bushing and other thrust washer.
38. Push the shaft into place and fit the other bearing onto
it, locking ring and s crew in the shaft nut.
39. Tighten progressively the nut with tool ETV 893 490
and measure now and then the bearing rolling resistance
with a spring balance. Always after tightening, rotate the
shaft many times.
