This old tractor sat outside forgotten for many years[like most i suppose] I finally got her unstuck after only two weeks and she has one clean cylinder and one terrible. I had to cut trees out that had grown through and fight a hive of honey bees which had settled into rear tires just to salvage it. After all that I plan to make her run one day. [Reply]   [No Email]

B blocks are cheap and plentiful.   [Reply]  [No Email]

If that is the case there is no reason to have to sleeve your block. Just go for the late B pistons. They are cheap and readily available. That would be 3/8 of an inch of bore over your stock 4.5 inch, which I would have to believe would take care of even the worst pitting... According to the same post the piston pins are the same size so no rod change will be necessary, only new piston pin bushings in your rods.   [Reply]  [No Email]

Been working about a month on freeing the thing up and finally got it to turn yesterday. Absolutely amazed at how much fasteners can rust on an old tractor . Also amazed at what atf,diesel,motor oil, beating on , and patience can do to take one apart !!   [Reply]  [No Email]
