oliver 4 cylinder engine identification help

William Cunningham · Sep 18, 2015

I picked up this 4 cylinder engine which was off a man made tailer backhoe. The guy said his dad pulled this engine from a old Oliver combine. He said it ran good just hasn't run in a couple of years. He changed it out because it had no electric start. It only has a hand crank. I cranked it many times it never hit, hope to get it going. My intentions are to put a belt pully on it and run a buzz saw. From the picturs can anyone identify it or give me any information on it

I can't see it real good, but maybe the same as a Oliver 60 tractor motor.

Nope. Just checked . Manifold is on the wrong side. Maybe a 66.

Looks like a flat head

William Cunningham · Sep 18, 2015

Yes its a flat head. What year do you think it is from?

J.Wondergem · Sep 18, 2015

Yup. Looking at it some more it looks like a Continental motor.

Might be a continental ? Look close at the sides of the block for a tag riveted on.
Some closer up pictures would help us.

Likely a Y91 Continental.

Not a 60 motor. 60 used a 125ci overhaed valve motor

That link shows a pic and that looks like the exact same thing. Hand clutch...the stand even looks the identical

William Cunningham · Sep 18, 2015

If I can get this running, any idea what the set up is worth?

Looks like a Hercules similar to one in a Cletrac HG

Continental from a combine for sure

rrlund · Sep 18, 2015

I had one identical to that,gas tank,radiator,the whole works,on a model 15 pull type combine.
I don't honestly know if it's Continental or Hercules.

rrlund · Sep 18, 2015

I'm inclined to agree with you. I always figured mine was a Hercules without knowing for sure since Oliver used the Hercules engines in the crawlers.

My son has one that came from a A-6 Case combine....round gas tank and all.

William Cunningham · Sep 18, 2015

I was able to clean the tag off it is a Y91. now I have to figure out why there is no spark....

rrlund · Sep 18, 2015

I wonder if maybe Hercules had that setup available as a whole unit for different manufacturers?

I'd say its a Continental too because I have never seen a Hercules engine with the the exhaust up front its always in the middle.Front exhaust is common on Continental engines.
