Dismantling, assembly and differential check

Dismantling

Differential design


13 — the differential Case 14 — Spherical washers 15 — Satellites 16 — the Finger	17 — Conic gear wheels of power shafts 18 — Persistent washers 19 — the Roller finger

PERFORMANCE ORDER

1. Fix the case of differential (13).
2. By means of a drift beat out a roller finger (19) and a finger of differential (16) of the case of differential (13).
3. Remove satellites (15) with spherical washers (14) and conic gear wheels of power shafts (17) with persistent washers (18).
4. Check each element on lack of wear.

Assembly

PERFORMANCE ORDER

1. Insert a pin (046) into an opening in the differential case. 2. Establish both conic gear wheels of power shafts (17) with persistent washers (18) on a pin in the differential case.
3. Establish both satellites (15) with spherical washers (14) and turn them by means of a pin (046).
4. Instead of a finger of differential insert a pin (021) into the differential case for fixing of conic gear wheels of power shafts and satellites.

Check

PERFORMANCE ORDER

1. Check the moment of rotation of differential. It should make 5-30 Nanometers.
2. Establish a finger of differential (16) and a roller finger (19).
3. Take the differential case from a vice.
