When I took mine out there was 1 stuck, a shot on the bottom of the rod w/ a block of wood and a hammer and the sleeve slid out. There is an o-ring in the block at the bottom and the top of the sleeve is a slip fit so not that tight. I also used the block to remove the other sleeves. Block was like a hammer handle, good solid piece of oak or hickory. Once knocked loose they slide right out. Before reassembling the sleeves into the block, make sure the o-ring grooves are very clean and not pitted or rusty. Use a mirror to inspect.

My students are working steady on my '39 A. It is time to get pistons out.
#2 is stuck good, I think #1 and #3 might be a little bit. #4 "looks" like
it's free.
My thoughts are to have them disconnect the rods at the crankshaft. At
first, I was thinking to disconnect the rods, then try to roll the crank
enough to allow some free play so they can bang on the tops of the pistons.
But now I am wondering about just pushing the sleeve and piston--guts,
feathers, and all--out the top. I intend to replace sleeves and pistons
anyway, so I figure if it comes down to it I can heat the sleeves with a
torch once they're out.
How much force does it take to get the sleeves out?
Am I on the right track? #3 will be a little tough to get to the bearing
cap, but I think they will be able to reach them all. I would like to be
able to get them out before we split the tractor.
Thanks,
Al
