I am having a problem removing the cylinder from a bee style 049.

The engine is “new” (never been run) and it turns over freely. Using the appropriate wrench, I am unable to get the cylinder to budge. Any suggestions would be much appreciated.

Many Thanks,

Does the top of the cylinder have “flats” for a wrench?  If not, you’ll have to use pliers with a strip of leather( I use a 6” chunk of an old leather belt)  to protect the fins while attempting to turn the cylinder out of the crankcase with the crankcase held firmly in a bench vice with protective plastic/leather/smooth wood to hold the sides of the Crankcase while you turn the cylinder ( lefty-loosey)   If it were a used oily castor stuck cylinder, I would recommend using heat to help loosen the castors grip, but,  seeing’s how it is a “new” engine just being friction tight,  a overnight stay in your freezer may help the steel cylinder let go of the Aluminum crankcase. (Shrinkage!)

DO not ever stick anything through the exhaust slots and attempt to turn the cylinder , you will only succeed in ruining the cylinder....ask me how I Know! lol!

Found a older thread Dave P that said:
I heat the cylinder, avoiding heating the head, with a small torch until it's just barely too hot to hold and then hold an ice cube on the top of the head. Ten seconds later the head will loosen up easily. This works well with a stuck cylinder / crankcase too, only I heat the case and ice the cylinder.

Let us know if you still have problems after trying these steps!

Heat is the best way to remove it. Really heat and wear gloves

Yes, heat.

Also protect the cylinders exhaust ports by putting masking tape on each of the wrenches forks and ensure it is fully extended in all the way. Ensure the fuel tank is removed and if you have a vice buffer the jaws with a cloth and just snug it up on the case. Do not tighten. Makes it so much easier to remove the cylinder using both hands to steady it.
