IHC Power Unit

Tue Feb 08, 2005 11:08 am

I'm looking for info on this powerunit for a buddy of mine. He says it runs well and he even picked up a nice hammer mill with it. He is trying to get the S/N but it is almost gone. I ask him to get what he could. He did find a number on the block UAAM 9213 K . Any info would be appreciated.



Thanks Ron

He told me he thought it was a cub engine and after I saw it I said nope. It still has the orginial dealer sticker on the gas tank and was sold in Gainesville, Georgia.

The gas tank and the radiator look to be the exact same as the tank & rad on my Cub power unit.

The Continental was also a flat head. This power unit is one from the internation 113 C.I. series like was in the A, B, and C.

George, Thanks for the info. After I posted I got to thinking that a continental was also a flathead because I had one in an old willy,s station wagon that I owned years ago.

The engines from Super A's were also used in power units. they have overhead valves. The book for the no 64 harvester thresher, I sent a copy of it to Rudi, lists it as 355 868 r91 Gasoline Burning Engine. The drawings on page 194 and 195 look like your pictures except your pictures show some extra tin work around the exhaust manifold. perhaps you have an added heat shield or repair??? My book shows a IH H4 mag. You seem to have the same type oil filter where the whole can comes off not just thetop like a cub. From what I see in the book it uses a Zenith carburator. You could have the 355 046 R1 or 355 046 R 12 head.
Does any of the help ID the unit for you?

Thanks that helps a lot. I think we can go futher if he can get me the serial number. He hopes to have it by this weekend if so I'll post it here.

It is a 113 ci engine, as George said. The name for the complete power unit is U-2. The engine number "UAAM" is consistent with that. The "K" suffix on the engine number probably means it is a kerosene engine. It appears to have kerosene/distillate manifold and carburetor. Farmall A's came with 3 different brands of carburetors and I assume the power units did as well. The serial number plate is on the flywheel housing. A corner of it is showing in the left side picture. The serial number should have a prefix "UAA".

This one has a water pump as well. It was an option for power units even though they were not on the tractors at the time this one was built.

Have him take numbers of the castings too. With them we can prove it to be a Super A and get near the date of manufacture. The Thresher manual covers covers the ebgine parts too.

I hope to have time tomorrow evening to stop by and get the serial number and casting numbers too.
Thanks Jim & Bill for the info thus far, I hope we can come up with the year it was manufactured. He would be happy to know he could get a manual too.
