It is necessary to replace the damaged details.
Transmission assemblage
Transmission assemblage is carried out in sequence, return dismantling. At assemblage it is necessary to consider the following. Each pair of gear wheels steals up at factory on noise, therefore replacement of gear wheels can cause some increase in noise of a transmission.

Fig. 5.20. The complete set of rings of the synchronizer of 1st — 2nd transfers: 1 — an external ring; 2 — an average ring; 3 — internally a ring




At selection of rings of the synchronizer to cones of gear wheels of 1st, 2nd, 3rd, 5th transfers, a backing and a primary shaft it is necessary to pay attention to that rings densely adjoined to a cone surface. Rings are necessary for grinding in to cones; the surface of contact of a ring with a cone should be not less than 80 %. External, average and internal rings двухконусного the synchronizer of 1-1-2nd transfers get used simultaneously and after grinding in form not divided complete set (also as well as the ground in gear wheels and rings одноконусных synchronizers of other transfers). In 10 kg compressed under loading the complete set of rings двухконусного the synchronizer discrepancy of end faces And and In (pиc. 5.20) an external and internal ring from position in one plane should be within 0,1 mm.
The backlash between an end face of an external ring and an end face прямозубого a wreath on gear wheels of 3rd, 5th transfers, a backing and on primary to a shaft for new details should be within 1,1—1,5 mm.
