connecting rod

On the 77 I'm rebuilding the one connecting rod is all rust would it be safe to use if I cleaned it up as good as I could? Also would it be safe to cut the sleeve with a torch to get the piston out its so rusted to the piston I don't think there's any other way
 
I'd hate to say on the rod without seeing it,but as far as the sleeve is concerned,they're a wet sleeve. If you can get a good stout rod up in to the bottom of the piston and put a jack under it,it might pop the sleeve and all right out. They're tapered at the bottom and once you break the seal of the o-rings in the bottom,you should be able to lift it right out by hand.
 
I suppose you are rebuilding the engine on an Oliver 77. If so and you want to remove the piston from the sleeve to be able to remove the piston pin. I would press it out or take a ball peen hammer and break the sleeve as it is thin cast iron. Cast iron is not cut with an acetylene oxygen cutting torch.
 
I tried that jack like you said and it just lifted the tractor I had a block of wood on the connecting rod as it is still connected to the piston in the tractor
 
Push the sleeve out with the piston in it and then cut the sleeve.
I would definitely not use the torch on it while it is in the block or you may not get it out at all
 
Keep the pressure on it and heat the head around the sleeve with a torch, It may expand enough to release the sleeve.
 
If you have and air hammer chisel/punch set you could drill a round bar that one of the punches would slide in and walk the bar around the bottom of the piston while holding the trigger. You can do the same with the sleeve.
 
Dad used a jack to push on an AC WC. Tractor raised up, like yours. Couple whacks with a post maul on top of the channel iron frame, and it popped loose!
