replacing a C-113

I have a 1947 Farmall b with a rusted out stuck engine on it. conveniently I had a C-123 off of a T-55 baler. is there anything i should be aware of when changing the engine. Any help appreciated thanks.

If you swap it out in total, no. They are the same block, with different sleeves. the C-123 will have a water pump, but if it already has one, no issues other than you may have height problems with the B hood and grille for the water pump clearance.

Does the 123 have a starter that would be the only difference as to getting a fit. The height of the engine is the same and your radiator will work just fine the water pump makes no difference as it probably didnt have one anyway. I have two of those engines and there will be no problems with one big maybe. Since the engine did come from a baler it mite not have the bore for pilot bearing as baler engines did not have a clutch. Talked to a fellow at a show who used one and handdrilled the crank for the pilot bearing didnt have anyproblems as he used the tractor a lot. That will be the first thing to inspect to see if your engine does have a place for the pilot bearing. Myself if i had the problem i would stand the engine on end and rent the big Mag base Millwauke drill and it would be a piece of cake. Just get a thick piece of plate for the drill to attach to. The crank will have some sort of center so you can locate and drill out for the pilot. Drilling in steps till you get the overall size for the pilot. I did a $250,000 job on some aircraft tooling using the big mag drill had to buy some tooling for the job but made it work as the drill is very accurate you will never have a problem with the pilot bearing. Let us know how it comes out. By the way your block mite take the 3 1/4 hi-dome sleeves and pistons giving you 135cu in.

I forgot does your engine have the plate for the hy pump its easy to add hy i have made a short stub on the settering shaft for the u-joint to clear the pump something to ponder as it has been done.

The C-113 has the notch out for the pump on it and the C-123 has the notch for a pump to and the C-123 has a dipstick on it and the cut out for the original starter where i was just going to weld some 3/4" steel on to the engine.

Ive seen several of those engines used none had the place for the starter filled in. So if you want to put a hy system on you just need the pump and a short shaft on the steering shaft to clear the pump not hard to do. Have you checked the crank for the pilot bearing as you will need it for the tractor.
