Hello,

I have a friend who has come across an IH Power Unit he believes is out of a combine. We have a serial number of 64HTC8389. Could anyone tell us if this is a Type A, B or C Engine?

Thanks
 
If I remember right that is a C60 (Cub Engine). You can look at it and tell, it will be a flathead engine if I am right.
 
The A B and C were all 113 cubic Inch engines, the Super A and Super C were 123, a 1/8 inch bigger bore! But as far as a serial number i cant shed any light on that. There was another guy asking about a bell housing, with a over centering clutch, for a stationary engine wanting one, but he did find one! My dad bought a new No 64 IHC combine in 1953, it had plenty of power for that job. That didn't have a hand clutch but it was controlled with a rod that could be reached from the tractor seat, and sped up the motor as the clutch was engaged.it was pretty nifty for it's day, i thought as a kid !

I am pretty sure only the very late Super A's had a 123 engine. My 53 does, but I believe prior to that they had 113 cubic inches like the A but with the added hydraulic pump.
 
Only the last 500 or so Super A's (SA-1 on the tag, I've been told) had 123's, the rest, like my '52, had 113 sleves. We pulled mine apart in the winter of 2018 & it had a 113 bore w/cast pistons. We replaced it w/113 bore sleves & aluminum pistons. jal-SD

I believe super A' s above serial number 310299 had the
123 engine from the factory. They have the bigger 3.436 inch lower sleeve diameter.
 
The Super A except for possibly the very last ones, had 113 cubic inch engines. The only thing SUPER about the Super A was the hydraulics and the thicker fenders. to support the rear rock-shaft.
 
be nice to know the combine # as there is so many ihc engines in different combines. or post a picture of engine.
 
Looking at the serial number you posted I'm guessing it's a #64 Harvester Thrasher combine and the engine would be a C-60 like the Farmall CUB tractor used.

The larger pull type combine was a 76 and that used the C-113 engine. I grew up with the 76 combine and spent many hours pulling the combine around the field with the Farmall 350 tractor.

I bought a engine from a 64 combine this last fall and I was surprise that it still turns. I have the carb off and trying to get it cleaned so I can try to make the engine run one of these days.
 
Dad had a brand new 64 in 1953 but ordered it with the 113 engine...which is still running a
generator for an irrigation set up today!!
 
you say "out" is the engine in a selfpropelled or a pull. The 113 engines were used on combines and balers. Some combines also used a Contenetal. Some balers even used Cub engines I have seen all of them one time or another. If the engine is an overhead it would be a 113. Combine engines had a clutch balers used a tightener on the belt.
