Technical OLD Crankshaft

Cleaning out My shop and came across this crankshaft upstairs in the attic ....Looked in all my old Federal Mogul Shop Manuals but cannot figure out what make it is....anyone have a clue? Old enough to have a slinger ....cast # 2SA701B also says PARK

 

i have no idea , but the background in your 2nd picture makes me curious as to what type of shop you have

i wonder what else could be found there?

 

Do I see seven main journals and six rod journals?
Might be a helpful clue.

6 or 12 cylinders?

 

Automotive Machine Shop .....established in 1938

 

well that is interesting !

 

may help Ohio Crankshaft Company

6 cyl 7 main bearings probably 1920s should narrow it down. If you can measure the bearing diameters that is another clue. It should be possible to figure it out but with a lot of time spent looking thru old manuals.

You might try asking these guys. Chances are someone will give you the answer within an hour.

From the length of the crank the bore centers must be huge I'm betting truck

 

That thing is huge ! I know that’s what they all say ! I’m betting an off road piece of equipment , Dozer , Tractor ?

Performance flathead Mopar I6?

 

Went thru 2 AERA casting number books today with no luck. Size suggests something in the Waukesha - Hall-Scott range

 

I was thinking Truck too..

 

FWIW,,,closest # I found was 2SA-101,,,REO,, '32-'''39. From a 1963 FM spec' book. What are the journal sizes, and stroke?
