Identify this engine Please

I think this is an American truck/industrial engine - probably early 30's vintage. S.F. Co. casting mark also shows up on Waukesha-Ricardo Cylinder heads from the mid-20's.

 

So how high from pan to rocker cover & how long is the head ?

 

So it looks like the SF Co. is the foundry that cast the head and block
and is probably not an indication of the engine manufacturer.

Is that a clutch shaft, on the right side of the bellhousing ? It's definitely interesting,, and different !!

I think you guys are referring to an engine that nathan posted in post #13, the original pic shows pedals made to the left side of the engine.

 

I will measure the engine next monday when I get back to the warehouse.

I'm trying to figure out how it worked with 5 ports for 4 cylinders. Which are intakes and which are exhaust?

More pix please -- that's an interesting old piece.

Could it have come off a tractor? Any idea what the gear ratios are like?

That part on the front where the fan drive would be look like a lot of stuff for just a fan -- could it have been some kind of PTO?

 

I'd bet the two center cylinders shared an exhaust port as well as the intakes being paired and tractors usually have a pretty substantial transaxle.

 

This kind of stuff drives me nuts until I figure it out.

I believe that I found it.

 

^Bingo!^ What is it?

Dang! I even searched Nash and missed it. You're good.

 

I say that the rockers are offset from the centers and they're assembled incorrectly

 

That would make sense with casting marks the same,being Waukesha and Kenosha are not too far apart in Wisconsin

 

You're the man

 

You guys are unbelievable.
I knew if anyone could figure it out you could.
Way to go "the-rodster" You ARE the man.
