33b — the Flange
33c — the Ball bearing
50 — the Reducer
54 — the Back cover

56, 56b — Bolts
70b — the Piston

 PERFORMANCE ORDER

1. Remove a reducer (50).
2. Merge oil from a reducer.
3. Remove a back cover (54).
4. Disconnect a lock ring (30).
5. Remove a flange (33b).
6. Remove the ball bearing (33c).
7. By means of the screw-driver to a vypressuyta a rubber cover (70d) from a bearing cover.
8. Insert a stripper (07l) into the piston (70b) and remove a sealing ring (70j), remove a rubber cover (70d) from the piston (70b), remove the piston (70b) from a side cover of the bearing, weaken a tube of a sapun (shooter).
9. Remove sealing rings (70h) and (70i) and do not establish them twice. Grease carefully the piston (70b) with hydraulic liquid (specification 343.0) and press it. Grease connection of a sapun after a piston press fitting. At a piston press fitting in a side cover of the bearing, be convinced that grooves were combined with a roller finger (70c) or an opening (shooter).
10. Replace a sealing ring (70j), - for this purpose, grease a sealing edge with universal gipoidny transmission liquid and press it by means of a drift (073).
11. Using a press of small diameter (072b), press a rubber cover (70d) on the piston.
12. By means of a press of bigger diameter (072a), press a rubber cover (70d) on a side cover of the bearing.
13. Further all procedures are carried out upside-down.
14. Pump over hydraulic system of blocking of differential.
