[Farmall] 39 Farmall A: Getting sleeves/pistons out.

[Al Jones]

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
