Farmall Super C Maybe

[Gary Puckett]

I just bought what I thought was a Super C. It seems to be a solid tractor. It has the Super C characteristics: Curved pedals, water pump, disc brakes, temperature gauge on the touch control. The date codes are "Y" 53 except for the engine which is "S" 49. I have read that a water pump could be added to a C 113. The block ends in R 069 indicating a C 113. Would you agree that it is not likely a C 123 which a Super C should have? I have read that C113 can be sleeved up to a 123? Thanks

Has it got a Super C serial number (over 100,000)? Sounds like a Super C that had a bad motor replaced with that was available.

The easiest visual for a Super C is the extra space between the crank hole and the last bar on the grill. I think all the sleeve kits for C113 are 3.125 now so they become 123 cubic inches. There are differences with the C123 block and It can take 3.25. Like @Jim Becker says the block was probably swapped with an earlier one. Good luck with it.

Thanks Jim. Yes the serial number is 167000 +.

Thank you. That is like mine.

Part number for the block is behind the oil filter canister, use it for. parts

Would there be any identifying marks on the pistons that would indicate whether the sleeves are 123 that you could see with a scope?

The block will be either be c113 or c123 based on the block number. The c-113 sleeves will be either original 3" piston or maybe 3.125 if aftermarket (thinner sleeves than original). If c123 original pistons will be 3.125 or maybe 3.25 if aftermarket. the c-123 sleeves don't fit a C-113 block. You can't tell what it is with a scope. I don't know all the differences of the blocks during the transition years between c-113 and c-123 engines in B's A's, C's Super A's Super C's 100s 200s etc.

I thought that would be the case. I know it is a C113 by the block number. Thanks for the explanation.

If I may, I would like to expand my original question. I looked at the piston tops with a borescope. I think the 113 and the 123 originally had flat top pistons. These pistons have a raised section about one inch wide running from to back. My eyes may be deceiving me; it could be a lowered section. Is this a clue that any of you know about showing what kind of rebuild it may have had? It looks either a "O" or "C" stamped in the piston.
