1. Remove a transmission from the hydrotransformer.
2. Remove multidisk brake В3 (133) and spring laying (133b), having taken out a lock ring (133а) from the transmission case.
3. Unscrew bolts (11).
4. Take multidisk brake В2 (14) of the transmission case.
5. Remove a blocking gear wheel at "Parking" (15).



Assembly is carried out as it should be, the return to dismantling. Check and measure a gap in multidisk brake В3. A gap of "L" in multidisk brake В3: 1.0-1.4 mm.

Establish disks of brake В3 together in an order presented on an illustration 12.6, and insert them in turn. Measure a gap of "L" between a lock ring (133f) and an external disk (133а) in three points. During measurement the lock ring (133f) should concern the top ring of the bearing in a groove of an external support of a brake (2).

Adjust a gap by means of lock rings (133f) if it is necessary. Thickness of lock rings: 3.2, 3.5, 3.8, 4.1, 4.4 and 4.7 mm.
