As the result of a generosity of a fellow Stovebolter responding to a "6V Starter Wanted" ad I placed in the "Swap Meet " section of this forum...I now have a 6V starter on my workbench.
I checked the diameter of the shaft as suggested by Bill Hanlon's unpublished Tech Tip and it indicates that it is a 6 volt unit.
I couldn't find a part number on the unit, though I did find some numbers.
The starter has a tag stuck to it (under the dirt) that indicates that it was "remanufactured" at some point. The seller said it came off of his '54 and was working before he removed it.
I have a concern about whether the drive assembly is supposed to float freely as far out as it does. I have posted some photos of the unit that show the extent to which the drive assembly can slide out (toward the flywheel) and wonder if that is as it should be.
It looks as though someone has modified the lever a bit, but I assume that won't be a problem. If it is, I probably will figure that out once I try to install it and see if it functions.
I would also assume that it makes the most sense for me to clean this unit up a bit, get a new switch for it (the one that was on it does not have the terminal on the side that I will be needing) and give it a try.
