- remove circlips 8 (see fig. 3-42) and spring washer 14, then
press out the differential pinion shaft and remove the differential
pinions and the drive shaft gears with support washers.
Press out worn or damaged oil seals from the front axle case,
from the front bearing cover and from the rear cover. Undo the
nuts from the axle support pad and remove brackets assembly.
The reassembly of the transfer box
is carried out in
reverse sequence. Pay attention to the following:
- reassemble the interaxial differential, having matched the
marks on its cases so that not to disturb the balance of this unit;
- the spring washer on the differential pinion shaft should be
placed from the blind hole side on the shaft end face;
- the axial gap of each axle drive gear should be 0-0.10 mm,
and the gear moment of resistance to rotation should not exceed
14.7 N•m (1.5 kgf•m). If the gap is greater, renew the support
washers with those having bigger thickness; if this will not help to
obtain the specified gap, renew the gears because of their exces-
sive wear;
- drive- and layshafts are installed in the transfer box casing
simultaneously (see fig. 3-44);
- bearings are press fitted on the differential casing with tool
67.7853.9558 (see fig. 3-45);
- the working surfaces of oil seals are greased with ãàíéã-
24 before their refitting in the covers and casings;
- threaded connections are tightened with torque specified in
appendix 1;
