[Prowbar]

One thing that I noted when driving with this transmission still installed was the lack of 2nd gear synchronization, even at low speeds and with hot gear oil.

Looking at the synchronizer surface, it became clear that it needed to be freshened up. Figured I could do this myself.

Indicated the first gear in the lathe (see photos) and placed the compound slide in the correct angle. The grooves are actually grooves, and not cut as threads, which makes recutting possible using this lathe.

An 45 degree V-groove tool was used to cut the grooves with the correct pitch.

Fresh grooves should allow for the oil film to be cut and easily evacuated during synchronizing.

I also polished the 2nd gear synchro for a fresh surface without burrs and damaged areas.
