model 60 to A pistons

[unstyled Bob]

I have a aset of standard size gas pistons from a model 60 I had to bore to 1/8th over,so had to buy new pistons for it. I also have a 49 "A" that is all fuel pistons,standard size. Now my question ,Will the pistons from the 60 fit in the A to give it more compression? I know that there would be a prob if the bore on the A is wore,but it seems to be very low hr tractor,and all that would be checked and the piston skirt clearance checked.

I put a set of gas pistion from a 60 john deere in a 52 A and it really gave it alot more power but sounded more like a 60 than an A,sold it and the man was very happy with the performance.

A late gasoline A (584,000 and up) and a gasoline 60 used the exact same piston from the factory, so there won't be any difference. If you want to increase compression, use an aftermarket set of aluminum pistons. Mike

The ones I put in were just a little longer than the A.And it did boost it a little.Sorry to disagree.

My mistake, Now that I tought abought it they were out of a 60lp.now I thing I got it right.

But he said he has an all-fuel A not a gas one.

So I would say it depends on how late all-fuel A's were made. Did they use lower compression head or just pistons ? If just pistons then the 60 gas ones should perk it up.

Mike M, I overlooked the "all-fuel" so the gas pistons certainly would raise the compression. The heads were the same, and the pistons were different between the all-fuel and gas versions. Sorry if I confused the issue. Thanks for pointing out the error. Mike

60 pistons should really wake up an all-fuel A. They sure will raise the compression but I would think that's just what you want...unless you got a thing for burning kerosene or some diesel/gasoline mix you brew up for your A and wann keep it low compression.
