Hey, Lumpy.  You got a great bunch of modelers up there in the Gold Country.
Surely one of them can help you.  If not, stop by the SAM flying site at 11000
Florin Rd on any weekend.  You will get help there.

Warm water.

Put the crankcase in there, leave it for a few minutes, then the cylinder
will drop out. The bearings may need a push - use a piece of dowel and
maybe hotter water if they are really tight.

The warm water expands the aluminium crankcase much more than the steel
liner and bearings, so they come loose......

Easy job.
