Farmall F-20

I'm going to help a friend of mine build an F-20
for pulling. I need to know what is being used for sleeves and pistons. I did some research on this a while back. I know that TSC made a 4" piston kit for them. It appears that JD 3010 or 4010 pistons have about the same dimentions. Will they work? Will the sleeves work? I think someone told me that when the 4" kit was put in, you had to bore the bottom of the block where the O-ring goes. I know the F-20 sleeves are smaller at the bottom. Any thoughts on how well the crank will hold up? He doesn't want to put a different crank in right away. I pull a different brand, but I collect Farmalls and I have often thought about building one of my F-20s for pulling. That is why I am trying to help him out.

I Have been pulling an F-20 since 1980 I started out with 4 inch pistons (they are a bolt in with no boring) and could get 55 hp with a stock crank. For about the last 15 years I have been using 4.5 inch pistons out of a IH 549 gas engine and am getting 70hp with a stock crank. I don't go to any of the big pulls but can hold my own in my club. There are some hard running tractors in my club. Chuck

I've never worked on a F-20, but I've been told they need some real good head work (thickness and port work) to make the best HP. If your going to buy new pistons, you might as well stroke it. The pin height will be differant on a stroker piston so there's no reason to but new pistons twice. Good luck.

The crank shaft in an F20 is only supported on each end. To make matters worse, ball bearings are used as support. While this reduces drag, it can mean that you will spend $400 or more for a set of bearings. The crank is forged steel and I know of at least one guy who stokes the cranks. He uses 3020 or 4020 pistons and sleeves with some machining work. The problem however will always be the crank shaft. Without support in the middle, it will eventually suffer fatigue failure and break. The same person who put the JD pistons and sleeves in an F20 through a rod through the side of the block and seperated the right frame rail from the tractor. A total loss. I just freshened my tractor and called it good. Thin wall sleeves and a new set of rings was good enough for me.

An M would make a much better tractor to modify for pulling. You get to start with a center supported crank and aftermarket pulling parts are readily available.
