2 — the transmission Case
3 — the Pallet
3a — the Strut
5 — the Oil filter
12a — Teflon rings
18, 67a — Laying
19 — the AT Electrohydraulic control unit
20 — the Radial epiploon
21 — the Directing plug
21a — Sealing rings
47 — the Nut
48 — the Output flange
67 — the Ball bearing
68 — the Lock ring



1. Weaken the directing plug (21) and remove it from transmission.
2. Remove the pallet (3).
3. Remove an oil filter (5).
4. Turn off bolts (19a) and remove the AT (19) electrohydraulic control unit.
5. Remove a flange (48).
6. Vypressuyte a radial epiploon (20), remove laying (67a), a lock ring (68) and a vypressuyta the ball bearing (67) from the transmission case.
7. Remove laying (18).
8. Turn off a bolt (1a) and (2a) from the case the hydrotransformer and transmissions.
9. Remove the case of transmission (2) from the case of the hydrotransformer (1).



1. Grease with sealant and insert into a groove everything together teflon rings (12a).
2. Install the transmission (2) on the hydrotransformer (1). Combine disks of brakes of B2 and B3.
3. Wrap bolts (1a) and (2a).
4. Measure a gap between a doggie of the parking brake and the ball bearing. It has to be within 0.3-0.5 mm.
