Edit: I goofed - please read my reply (#5).

I promise I have googled and searched this:

I am elbows deep in a trans that was original to a 1941 pickup.

I counted the teeth on the cluster gear: 29. I counted the teeth on the input gear: 16.

I don't have a whole lot of transmission experience, but I thought the only viable combos were 15/29 or 16/28. I have often heard and have quoted myself the "rule of 44".

These gears have run in this transmission and ran together very smoothly before I pulled it apart.

I suspect they may be replacement gears, they do not have Ford markings.

The cluster bears the marks "RG CO. 316-11B USA NH"

The Input (MDG) bears RG CO. 216-1 NF USA"

Richmond Gear???

Any ideas?

Mart.
