Thanks for the suggestions guys. I didn't want to try running a weld bead down the cylinder since those cylinders
are so long and burning through could be diasasterous.
I ended up making a sleeve puller on a lathe I just bought, made
a full length plug slightly smaller than the piston with larger
ring left on the cylinder to catch the sleeve. Then I used a peice
of 4" pipe, a bit longer than the sleeve plug and used another machined
peice that fit into the end of the pipe. Then I used a peice of 5/8 threaded rod and some nuts, and large wrench to pull out the
sleeves. Making the rig took the longest time, pulling out the sleeves
and pulling in the new sleeves took about an hour.
My sleeves ended up being the thicker variety, so I had to return the sleeves I originally purchased and
get some thicker ones. I don't know why this rig wouldn't work on the thinner sleeves
also.Anyway if anyone wants to buy this rig I'd consider selling it. The whole thing must weigh about 50 lbs since the plug was machined out of a solid
chunk of steel. Also the pipe was faced in the lathe so it is perfectly square and the
pulling plate was also machined so it is perfectly square. I didn't want to pull the sleeves
in cockeyed. As I said it should work to remove and install the
sleeves from all 9N, 2N, and 8N tractors. Let me know if anyone is interested. Dave : : Guys,
