Multidisk brakes В2, VZ and a blocking gear wheel at "Parking"

2 — the transmission Case
11 — Bolts
14 — Multidisk brake В2
15 — a blocking Gear wheel at "Parking"

133 — the Multidisk brake
VZ, 133а — the Lock ring
133b — Spring laying

Check of a gap of "L" VZ in a multidisk brake

2 — the transmission Case (an external support of a brake of VZ)
14а — the Piston
133а — the External disk in thickness of 6.5 mm
133b, 133с — External disks in thickness of 1.8 mm

133d — the Disk spring
133е — Frictional disks
133f — the Lock ring
«L» — the Gap



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



1. Assembly is carried out as it should be, the return to dismantling. Check and measure a gap in a multidisk brake of VZ. A gap of "L" VZ in a multidisk brake: 1.0-1.4 mm.
2. Establish disks of a brake of VZ together in an order presented on an illustration, 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.
3. 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.
