How to Assemble the Synchronizer Assembly

Special Instructions

Assembly should be done on a clean, flat surface slightly lower than your waist.

Pins on the LO range synchronizer must line up with the chamfered holes on the sliding clutch bottom.

When compressing the HI range synchronizer springs cover with a shop rag. In the event compression is not achieved the first time, this prevents the springs from leaving the bench area.

Procedure -

1. On the bench place the larger LO range synchronizer ring face down with pins up.

2. With the sliding clutch recessed side up, place the sliding clutch on the LO range synchronizer pins.

3. In the HI range synchronizer bores, install the three (3) springs.

4. Place the HI range synchronizer ring over the LO range synchronizer ring. Rotate the HI range synchronizer until the springs are seated against the pins.

5. Cover the assembly with a shop rag.

6. Apply downward pressure to the HI range synchronizer ring while twisting counterclockwise. This compresses the springs to fully seat HI range on the LO range synchronizer. This should be done with a rapid twist and push motion.

Note: Make sure there are three springs and they are fully compressed.

Note: Make sure you can move the sliding clutch from HI to LO range and back.
