I understaqnd you were able to remove the sleeve but i thought I would offer some advice on how to prevent the engine from turning for the next time. Simply remove the spark plug and feed some soft rope into the cylinder through the spark plug hole. Be careful not to get the rope into the intake or exhaust port and leave plenty hanging out the hole. The rope will stop the engine from being able to rotate and make it very easy to remove threaded items from the crankshaft. When you are done just pull the rope out. Simple and works great with little risk of damage. I have used this technique many times.
