2. Before disassembly, mark the position of the clutch 3 relative to the hub 1. Carefully disassemble the synchronizer by removing the clutch from the hub. Make sure that spring-loaded crackers 2 with balls do not scatter in different directions.
3. Inspect the synchronizer parts. Chips and nicks on the splines of the hub and coupling are unacceptable (especially pay attention to the ends of the teeth of the coupling). Damage or seizing marks on crackers, balls and springs are unacceptable.
4. Replace defective parts or synchronizer assembly.
5. Install the coupling on the hub in accordance with the previously made marks.
6. Three large grooves on the splines of the coupling must coincide with the grooves of the hub for the clamps (with holes).
7. Lubricate the detent spring with grease and insert it into the hole in the hub slot.
8. Lubricate the cracker with lithol and insert a ball into its hole.
9. Compressing the spring, insert the cracker with the ball into the groove of the hub. Grooves a on the cracker should be outward, spherical (big) surface b - facing the coupling.
10. Push the cracker so that the ball falls into the grooves on the splines of the coupling.
11. Adjust the spring with a screwdriver so that it gets into the cracker hole.
12. Install the rest of the clips in the same way.
