Radiator cap

Postby Tractor Rod » Sun Feb 14, 2021 8:05 pm

:help:

I am getting ready to order a radiator cap for my 1947B and it might be a silly question but how do I know if it is a pressured or non-pressurized cab?

As I looked on the Internet to buy one I ran into the question of pressure or non-pressurized.

Thanks.

TM Tractors (site sponsor with link below) has the non-pressure cap, which your tractor should have. It has no spring...very simple cap:

Here is what the pressure caps look like:

Ignore Dale. She gave a Cub answer. :(

No B came from the factory with a pressure cap. In the off chance that somebody has installed a radiator with a pressure system type neck, test fit your gas cap on the radiator. The gas cap would fit the original non-pressure system. The top end of the overflow tube is below the cap.

Jim,
Are you sure you want to put the gas cap on the radiator?
:shock:

What I'm trying to say is to test fit the gas cap on the radiator. If it will physically fit the filler neck, the original style radiator cap will fit. I didn't say to leave it there.

But the gas cap would not fit a pressure system type neck. Thanks Jim, I understood what was meant.
There are two ways to get enough Cubs. One is to continue to accumulate more and more. The other is to desire less.
