3.2.6.1. Check of elements of a main shaft

Fig. 3.48. Check of a gap between gear wheels of the 3rd and 2nd transfers

Measure a gap between gear wheels of the 3rd and 2nd transfers (fig. 3.48).

If the gap exceeds a maximum, check contact surfaces of gear wheels of the 2nd and 3rd transfers, couplings of the synchronizer of the 3 / 4 transfers. Replace the worn-out and damaged details.

Gap: 0,05–0,20 mm.

At most: 0,25 mm.

Fig. 3.49. Check of a gap between a gear wheel of the 4th transfer and the bearing

Measure a gap between a gear wheel of the 4th transfer and the bearing (fig. 3.49).

If the gap exceeds a maximum, check contact surfaces of a gear wheel of the 4th transfer, the bearing and coupling of the synchronizer of the 3 / 4 transfers. Replace the worn-out and damaged details.

Gap: 0.17–0.37 mm.

At most: 0.42 mm.
