Synchronizers — overhaul (Opel Ascona C)

1. The synchronizer parts for 1/2 and 3/4 gears are interchangeable.

2. However, we do not recommend reassembling old parts that have already become used to each other.

3. If the hub teeth or synchronizer clutch are worn out, you can replace the specified parts separately, but if the synchronizer is generally worn out, it is better to replace it as an assembly.

5. To disassemble the synchronizer, push the hub out of the clutch, making sure that the sliding keys do not fly apart.

5. Remove the ring springs and keys.

6. The synchronizer is assembled in the reverse order. Check that the bent ends of the springs are on the same key and that the springs run in opposite directions relative to each other (see photos).









7. To check the cone rings for wear, rotate them on the corresponding cones. The ring should be "stuck" on the cone with a certain gap between the ring and the gear flange. If these conditions are not met, the cone rings should be replaced.
