1370 - 2670 Crankshaft: Same or Not

I'm still thinking about this 2670 with the crank that's probably bad. I'm also thinking that the crank out of this salvage 1370 won't fit, but I'm not sure on that. So you guys who know more about it than I do please tell me. Is the crank in a 1370 the same as a 2670? The salvage 1370 that I have was a fairly new rebuild that sat and stuck after the owner passed away. It has been stuck now for about 5 years and I've had no luck breaking it loose. Should have a good crank and LOTS of other good parts, but I just don't know if it is the same as a 2670. Thinking not.
 
Go to www.stollerih.com and click on parts on left side then click on parts arrow in middle of page then go to bottom of page and select Pontiac Store. This should open their parts book.

The parts site shows the same PN for those two cranks. mEl
 
Aftermarket bearings are different So I would say they are different. 2670 and 4690 have larger mains.
 
hAVE REALLY GOOD luck eith engine release and following their instructions of vibration on breaking loose engine. Put pressure on crank in one direction and set up something to vibrate long term switch direction occusionaly
 
The supplier whom I trust, shows the same part number for the Mains & Rods on the 1370 thru to the 4694. Stands to reason that if CASE shows the same part number for the crank, that the bearings would be the same. Get that tractor home!!
