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

[Tractorman453657 at aol.com]

Take the head off, then if possible remove the crank form the  block. then 
you will be able to drive pistons and sleeves  out with a block  of wood and 
a small sledge. then once they are out you can use a press to push  the 
pistons out of the sleeves. There are sleeve  pullers but  that  series engine 
has wet sleeves and should come out rather easy from the  bottom.

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
