3. Cover of a case of differential
4. Persistent washer
check persistent washers on existence of cracks
and gear wheels on existence of wear tracks
5. Semi-axis gear wheel
6. Axis of satellites
remove by means of a drift
check on wear
7. Persistent washer
check persistent washers on existence of cracks and a gear wheel on existence of wear tracks
8. Satellite
9. Nut of a bolt of fastening of a flange of a drive
the smaller fillet enters into a semi-axis gear wheel
10. Differential box

together with a leading gear wheel

Epiploon of a flange of a drive, removal

(the transmission did not act in film from the car)

PERFORMANCE ORDER
1) remove the filter for epiploon replacement on the right side
2) remove a semi-axis from a drive flange
3) remove a bolt of a flange of a drive (it is specified by an arrow), holding a flange by means of a drift
4) establish the pallet for collecting oil
5) remove a drive flange
6) remove an epiploon

Epiploon of a flange of a drive, installation

PERFORMANCE ORDER
1) establish an epiploon against the stop
2) grease edges with multipurpose greasing
3) establish a drive flange, tighten a flange bolt to 25 N of m.
4) establish a semi-axis on a drive flange, tighten fastening bolts to 45 N of m.

Prevention

If you use an old leading gear wheel / a gear wreath and bearings, in the beginning measure a district gap and the general moment of rotation of a conducting gear wheel before dismantling of the mechanism of the main transfer. Use these values for adjustment at assembly.

If gear the wreath / leader the gear wheel, the bearing or a cover of the bearing were replaced, the gear wreath and a leading gear wheel should be adjusted anew.
