[quote="Garlic Pete"]This is on one of the 3T Salyer pump tractors. Salyer and Boswell had many 3T and 17A tractors with Sawtelle and Rosprim 24" ditch pumps for moving water. I have four chassis, one 3T nearly complete with engine, one 17A nearly complete with engine and two 17A with no engines.

I believe this is a 17A starter with the conversion kit mounted to a black adapter plate, which is bolted to the 3T flywheel housing.
Here is a photo of the starter boss on the 17A chassis next to it.

I know the 3T is a dry clutch and the 17A is oil, but I'm hoping that if this really is a 17A starter kit, the starter will be sealed and have the O-ring on it when we remove it.

If your so convinced that's what you have go ahead and try it and you will find out.
The only thing usable for the 17A there is the 50MT starter itself (no drive end housing).
Same for the 50MT that ag-mike has.
