Recommended Posts

ok guys i have 2 farmall cubs on here a 1948 and 1953 c60 motors in both...... my newest problem is rad caps, im trying to find the right ones and yes they r both different....the 1948 cub has a 7lb. cap on it and is roughly 1- 1/16" depth inside filler neck,2.22 od of neck and 2.09 tang to tang..............

 

the 1953 cub has roughly a 3/4" to 7/8" inside filler neck and 2.22 od outside neck, now i tried steiner they both look different than mine and the numbers didnt match up, and i also tried stant caps and theirs didnt look or numbers match ethier? now i kno i can just buy any old cap and it will probably work.......but i`d rather get the correct ones that look right fit right and have the correct pressure for my motor, so any ideas or leads appreciated and if u need anymore numbers or info just let me know thnx bb p.s stant saz cap#10228 is right and its not

IH released an optional pressure type radiator cap  part number 365892r91  around serial 185000. for radiator 365892r91  or 80889r91 if you have  radiator 352903r92 it did help some with cooling problems but the pressure cap can stress some of the old radiators parts are listed in the TC 37 F  IH parts book

The front bolster of the tractor serves as the lower tank for the radiator on the Cub. That's going to make the lower connection difficult if you're rigging something. I've used an aftermarket "will fit" radiator on a Cub and had excellent results.

The one I used was from that country that starts with a C. It was the cheapest one on ebay at the time, and just came in a white box with foreign lettering on it.

People call me names for this, but frankly, I believe they all come from the same factory no matter who you buy from. It's not like there is a huge market for Cub radiators that Chinese factories are crawling all over one another for that sweet sweet Cub radiator money.

Apparently the quality standard is a Clancy radiator, made in Ireland. A bit more expensive. My experience with them, meh. Last summer the 856 radiator sprung a leak. We pulled it out and it was a Clancy. In the process of pulling it out two of the captured nuts broke loose and spun even though I'm sure they were put in with never-seez. Had to buzz them off with the angle grinder. As an aside, the battery powered angle grinder is the BEST INVENTION EVER. Right now it has a Chinese ebay radiator in it, and the Clancy is waiting for a trip to the radiator shop.

The radiator part number would be on a tag on the radiator if it is an OEM IH radiator.

The R-number is the revision. Any revision is backward compatible with the same part number but a lower R-number. R3 would be backward compatible with R2 and R1. When you see R93, R92, R91, those are revisions of assemblies. In your case the radiator, cap, gasket, and overflow tube are an assembly.

What reason did the seller give when he told you it would not fit your Cub? Many sellers are just "drop shippers" and don't know a thing about the products they sell. It pays to be an educated consumer because you can save a lot of money by dealing with these folks, but you can't expect any intelligent support from them.

To my knowledge, there really is only one radiator design for the Cub.

doesnt take returns is usually a walk they are foreign and dont have a clue other than $$$

virtually everything will be from china as will fit which means you will make it fit

I will forward YOU 3 contact, if I find, that have slight sense ,you need to take the info and decide if the product /service is worth THEIR input $$,

If there are multiple possibilities and you are not sure what you have, then why not just take this to a radiator shop and let them tell you what you need? Yes, it will probably cost a little more, but you will get the right part. I have a shop close to me that I use all the time and they are very competitive on price. They don’t recommend cheap stuff, but if that’s what you want they will sell it to you. They may also provide a repair solution instead of replacement. May be worth checking out.

2 hours ago, R190 said:

How wide is the flange? Thats the widest part of the radiator not where you are measuring.

This. The 14-1/2" measurement is at the base flange of the radiator. There's nothing special or different about your Cub. It's just a regular run of the mill every day bog standard Cub. Go ahead and order the aluminum radiator. It will fit just fune.
