Bruce | | | | | Joined: Aug 2005 Posts: 1,186 Shop Shark | | Shop Shark Joined: Aug 2005 Posts: 1,186 | I guess this is not to quickie a question. From what I've been able to determine, in the '30s and early '40s they had a 9 tooth starter but what about 1950???
Bruce | | | | | Joined: Feb 2006 Posts: 649 'Bolter | | 'Bolter Joined: Feb 2006 Posts: 649 | I'm trying to remember what little I know about the starters. I just counted the teeth on 3 starters I have, knowing they came off my 216's that were in my 51 & 53. I come up with 9 teeth. The only difference I can recall is regarding 6 volt vs 12 volt changes to the flywheel. 139 teeth vs 168. The size of the starter drive shaft and gear changed also. I would assume the 30 & 40 startes had 9 teeth. If I can document it I will let you know. | | | | | Joined: Aug 2005 Posts: 1,186 Shop Shark | | Shop Shark Joined: Aug 2005 Posts: 1,186 | Thanks. I'm trying to help out a friend who is fixing up a '50.
Bruce | | | | | Joined: Jun 2009 Posts: 2,201 Shop Shark | | Shop Shark Joined: Jun 2009 Posts: 2,201 | I've got a 40 car starter still bolted up to the engine and transmission. If all else fails I can pull it and count. Looks like yakimabowtie has the answer for later engines. | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 |
The Master Parts book seem to show that the same number of teeth were used on 6v trucks back to the 30s.

I know the difference between the 6v and 12v flywheel tooth counts, but what's the difference in the tooth count between the starters?
Truck is a '54, 235 with a solonoid starter. It's got a 139 tooth flywheel and the owner wants to go back to the foot start. I've found a starter with 9 teeth and just want to make sure it's compatible with the 139 toot flywheel. | | | | | Joined: Dec 2008 Posts: 899 'Bolter | | 'Bolter Joined: Dec 2008 Posts: 899 | Not a 100% sure, but I think the 12 volt starter drive has 9 teeth with the OD. of the teeth = 1 inch. 6 volt starter drive has 9 teeth also, but with an OD. of the teeth = 1 1/8 inch.

But, sometime in the last week or so I thought I read the starter gears were different as well.
i.e. as mentioned in post #1

Give me ambiguity
or give me something else

If the gear diameter is different, I suppose I can just engage the bendix without the battery hooked up and see if the teeth mesh with the flywheel.
I ought to be able to see an 1/8" misalignment, even with my old eyes. | | |
