A radiator

Postby Fibber Mcgee » Sat Aug 02, 2014 3:47 pm

Are the A and Super A radiators the same or interchangeable?

I am not an expert by no means, However I believe that there is a difference in width between the bolts on the bottom. Good luck

The late A and early Super A are the same. The early A will not interchange due to the change in hood/grille fastening method. I believe the late Super A (not Super A1) had a pressure system, which would have a different filler neck. The pressure and non-pressure Super A radiators may interchange subject to some small details.

I don't believe late Super As had a pressure system. Only the A1 did as a holdover mule for the 100 because it had the C123. They all had the C113 with thermosiphon.

OK, I looked it up. According to TC-39B, the Super A went to a pressure system at serial number 336711, which is very last of '52. The absence or presence of a water pump is a separate question. Some C-113 power units had a water pump with a non-pressure system. Water pump was an option on the Farmall C which had a C-113 with a pressure cooling system.

The radiators on a '46 A and '50 Super A are the same.

Thanks for the radiator question and replies. After getting my Cub back into one piece (thanks, Cub Forum) I have begun digging into my Super A and welcomed this post/info. From this post, and my TC-39C, I have learned that my FAA351213 fits between the beginning of pressurized systems (336711) and the beginning water pump use (356001/Super A-1). Now to dispose of 3 non-pressurized A radiators that I had acquired BM (before manual) while thinking that those tractors without a pump were non-pressurized :oops: . These do not have the neck surface for the sprung valve in the cap to mate against. Turns out the pressurized one that I have does and is good and correct.

I also learned that some people (the PO in this case) will fill a transmission to the top :shock: , thus explaining a leak out of the LH differential shaft housing. I drained two full gallons just to get it down to the full level plug. Now to clean or replace the LH brake lining. The output shaft seal is likely still good for its intended purpose, but I have a new one on hand, so should I replace it anyway while the axle housing is off?

This may be the first of many Super A questions to come (to be shorter, we hope).

Are you wanting to sell the extra radiators? If so condition and price please, I may be able to take one off your hands.

I think the later pressurized radiators will sub back to the early non-pressurized. My Super A is a '48 and I had to replace the original radiator with a NOS IH radiator and the only difference that was visible was the filler neck.
