Engine: Need some starter motor help

[60 Lark]

I recently bought a 1960 Lark. My first Studebaker. 3 speed, V-8 259. Supposedly was barn find, purchased by the PO at an estate auction. He got it to a mechanic who went through the car and replaced item to get it running. New shocks, new exhaust, new tires, rebuilt compressor, etc. Might be a rebuilt starter?

My starter sounds like a chicken when I hit the key. I pulled the starter today. I've done some research but have a few questions.
The starter is a Delco 12v, #1107651. It has a 9 tooth pinion (the ends of the pinion teeth are worn off at a 45 degree angle). The flywheel teeth look OK. I have done some research on #1107651 and my findings are that it is for an automatic transmission. 31107650 Delco starter is referenced for the 3 speed.

So, do I have the wrong starter? If so which one should I have and where can I get one?

While I have you guys reading this, I don't see any indication that my transmission is an overdrive. At least I don't have the lever under the dash to engage it. Did they make non OD 3 speeds?

Thanks in advance.

On EBay there is a guy selling a mini starter modified to work for V8 Studebakers with manual transmissions. I bought one and it works great. I think it is the relatively common mini starter sold for Chev V8s with a faceplate machined to fit it on the Studebaker V8. It also has the advantage of turning the engine over faster for starting.

In answer to your other question, yes Studebaker built cars with straight 3 speed transmissions without overdrive.

I'm not sure which direction the 45* worn part refers to, but the starter teeth normally have a bevel to help with smooth engagement.

Standard and automatic transmissions have different starters, however with a little fiddling snouts and drives can be interchanged to make fit. I did some mixing and matching and was unsure of the mesh so I placed some play dough on the gears and rocked the engine with the starter engaged then removed the starter to inspect the mesh pattern in the play dough. There is not a lot of free play in the design, the teeth clear the bottom of the gear by about .017. That is why the correct bolts are important along with the bellhousing being dialed in correctly, a few thou here and there can cause starter trouble.
