Preliminary check

GAP OF THE GEAR WHEEL OF THE 3RD TRANSFER

PERFORMANCE ORDER
1. Measure a gap between a gear wheel of the 3rd transfer and a gear wheel 2-it transfers.

Nominal gap: 0,05–0,20 mm
Maximum permissible gap: 0,25 mm

2. If the gap exceeds maximum permissible value, check the surface of contact of a gear wheel of the 3rd transfer, a gear wheel of the 2nd transfer and a nave of the coupling of the synchronizer 2-oy/of the 3rd of transfers. Replace the worn-out or damaged details.

GEAR WHEEL GAP 4-EY TRANSFERS
PERFORMANCE ORDER

1. Measure a gap between a gear wheel of the 4th transfer and the bearing.

Nominal gap: 0,17–0,37 mm
Maximum permissible gap: 0,42 mm

2. If the gap exceeds maximum permissible value, check the surface of contact of a gear wheel, the bearing and coupling of the synchronizer 3-ey/of the 4th of transfers. Replace the worn-out or damaged details.

Dismantling

PERFORMANCE ORDER
1. By means of special OK130 171 013 adaptation remove the bearing from a shaft.
2. Remove a lock ring.
3. By means of a press and special OK130 175 008 adaptation remove the coupling of the synchronizer 3-ey/of the 4th of transfers, a ring of the synchronizer of the 3rd transfer and a gear wheel of the 3rd transfer.
4. By means of special OK670 990 AA0 adaptation remove the bearing from a main shaft.

Assembly

PERFORMANCE ORDER
1. Using a press and special OK130 175 A13/OK011 270 A02 devices, install the new bearing.
2. Establish a gear wheel of the 3rd transfer, a ring of the synchronizer and the coupling of the synchronizer.
3. Using a press and special OK011 270 A02/OK130 175 008 devices establish a ring of the synchronizer of the 4th transfer, a gear wheel of the 4th transfer and the new bearing.
4. Measure a gap between a gear wheel of the 3rd transfer and a gear wheel 2-it transfers.

Nominal gap: 0,05–0,20 mm
Maximum permissible gap: 0,25 mm

5. Measure a gap between a gear wheel of the 4th transfer and the bearing.

Nominal gap: 0,17–0,37 mm
Maximum permissible gap: 0,42 mm

6. If the gap differs from the required value, sort and repeatedly collect a main shaft of the transmission.
