18:16. Check of a rotor

PERFORMANCE ORDER
1. An ohmmeter check conductivity between brushes of a collector and a rotor. With conductivity, replace a rotor.
2. An ohmmeter check conductivity between brushes of a collector and shaft of a rotor. With conductivity, replace a rotor.
3. Establish a rotor on V-shaped blocks and, the indicator of hour type, check a collector beating. If the beating exceeds maximum permissible value, pierce a collector or replace a rotor.

Nominal beating: 0,05 mm
Maximum permissible beating: 0,4 mm
4. Measure diameter of a collector. If diameter is less than required size, replace a rotor.

Diameter of a collector: 31 mm
5. If the surface of a collector is polluted, wipe it. If necessary, pierce or process a collector an emery paper.
6. If depth of flutes between contact plates of a collector is less than maximum permissible size, replace a rotor.

Nominal depth; 0,5–0,8 mm
Maximum permissible depth: 0,2 mm

Assembly

PERFORMANCE ORDER
1. Establish earlier removed washers on a rotor shaft.
2. Install a rotor in the stator case.
3. Install the brush holder in a back cover and fix by screws.

Inhaling moment: 2,4–4,4 N • m
4. Install the obgonny coupling and a clamp of a lock ring on a rotor shaft.
5. Establish a lock ring in a rotor shaft flute.
6. Establish a clamp of a lock ring on a lock ring.
7. Install the lever.
8. In the presence establish planetary transfer.
9. Establish a forward cover.
10. From a back cover establish, and return hairpins.

Inhaling moment: 3,8–7,1 N • m
11. Insert a plunger into the lever.
12. Insert a spring of the traction relay.
13. Install the traction relay and fix by screws.

Inhaling moment: 4,1–7,6 N • m
14. Give tension of the rechargeable battery to the plug S and the case of the traction relay and check that the plunger moves forward outside and stops.
15. Measure a gap between a clamp of a lock ring and a flange of a forward cover.

Gap: 0,5–2,0 mm

Prevention

Do not give tension of the rechargeable battery on the traction relay during more than 10 pages.


16. If the gap differs from demanded, adjust it increasing or reducing number of laying between the traction relay and a forward cover.
17. Connect a stator coil wire to the plug M of the traction relay.
