Transmission Timing Issue

[Author nameAuthor names are only available to PAS members.]

I have a 1931 Model 43 with a Warner 3-speed transmission with internal free-wheeling. I currently have the transmission out of the car and I am having difficulty in finding one of the two needed timing marks. The mark I was able to locate was on the back side of the beveled cluster gear (lower shaft, non-sliding gear set). The mark was the symbol for female (circle with a cross protruding from it) and located in the center of a tooth.

Upon examining the back side of the upper shaft beveled gear (mating gear), I was unable to find an equivalent mark or a mark of ANY kind. On the front side of the upper beveled gear I saw two marks located in the valley between two adjacent teeth. The marks look like they were made with a very small chisel. One of the marks was located at the left most side of the valley and the second mark was made at a 30 degree angle and ended up in the middle of the valley between the two teeth.

Comments:

I would think that if I found a mark on the backside of a gear, I should find the identical mark on the same side of the mating gear (Both my friend with the Model 41 and I didn’t see any sign of a mark there).

I was unable to find specific enough information in the service bulletins, but I could have missed something with the computer searches that I tried.

Questions:

Could the two chisel marks that I described above possibly be the mating timing mark?

Is there any way I can time the transmission myself, on a bench? The only way that I can figure doing this is by rotating the upper beveled gear one tooth at a time (in relationship with the known mark on the cluster gear) and seeing if I have a smooth transition from both second free-wheeling into locked second and third free-wheeling into locked third gear.

Comments and suggestions would be greatly appreciated!
