6volt starter will NOT fit 12 volt hole and ring gear

[Lou Earle]

Was trying to get 6 v starter onto a 59 automatic to fast spin it-whole nother story- and discovered 6 v will not fit 12 plate.

Close examination show the 6 v has a larger diameter shaft. The 12 v is much smaller so the 6 volt will not mesh properly.

So it looks like a 12 volt will fit a 6 volt but not visa versa- tried 3 6 volt before I discovered the problem.

So beware a 12 volt starter might work but it will be loose fitting and teeth might not mesh very well.

6volt starter will fit most 1956 and older Plymouth and Dodge engines. I have a 1956 12 volt in my 1936 engine.

The flywheel ring gear was changed in '57 from the earlier 146 tooth to the 172 tooth gear that was used through '61. In '62 they went to the gear reduction starter and I believe that was different from the other two.
