Synchronizer details: 1 - hub; 2 - spring; 3 - cracker; 4 - ball; 5 - clutch
The grooves for the clamps have holes for the springs.
1. Before disassembly, mark the position of the coupling relative to the hub.
2. When disassembling the synchronizer, carefully remove the coupling from the hub, making sure that the spring-loaded balls with crackers do not scatter in different directions.
3. Examine the details of the synchronizer. Chips and nicks on the splines of the hub and coupling are unacceptable (pay special attention to the ends of the coupling teeth). There should be no damage or signs of seizing on crackers, balls and springs. Replace defective parts.
4. Install the coupling on the hub so that three large grooves on the splines of the coupling are opposite the grooves of the hub for the clamps.
5. Lubricate the retainer spring with Lithol...
6.... and insert the spring into the hole located in the groove of the hub.
7. Lubricate the cracker with Litol and insert the ball from the outside into its hole.
Note.
- 1 - the outer side of the cracker (large surface area);
- 2 - the inside of the cracker (less surface area).
8. Compress the spring with thin-nosed pliers.
9. Insert a cracker with a ball so that the ball falls into the grooves on the splines of the coupling.
10. Adjust the spring with a screwdriver so that it gets into the cracker hole.
11. Install the rest of the fasteners in the same way.
