Default How to remove a sleeve

I have a couple of motors that I can't get the sleeves out of. Every motor I've rebuilt in the past, the sleeve slid out with no problem. How are you guys getting them out?

I use a heat gun and heat the block (use hot pads or "Mechanics" kevlar gloves).

Typically a wooden popsicle stick through the exhaust port (or small plastic zip tie) and then gently turn the crankshaft; it will bump it out/up enough for you to pull it out with no problem. Just don't force it, if you're having to force it, heat it more.

*Sometimes* on older/less cared for engines there can be sever varnish between the liner/wall that makes it want to stay in. Use PB 'Blaster or WD40 (any reasonable solvent) and spray it up from the bottom around the sleeve and let it soak; then reheat and try again.

+1 Very sound advice!

Another helper I use is a rubber expansion plug

zip tie trick works like a charm 99% of the time without even heating the engine.

you can use the washer from a glow plug, the same way you would with the zip tie through the port. copper is softer and will not damage anything

And for the 1% when the zip tie snaps off you can use a corner tip of a towel
