Re: Help with Disassembly
I think that is the large splined Cox .049 engine. Take out the 5-40 tapered screw. Put in a hardned 5-40 cap screw and either use a arbor press or tap it off with a hammer. Careful not to break the plastic cooling fins if you want to save the flywheel.
These large splined engines make nice diesel conversions. A TD 09 or medallion 09 drive plate fits these engines. Just need to turn them down on the OD to look nice.

Just to add a couple more details to Jason's description, you put the crankcase on its back end on a hard surface with the nose of the crankshaft pointing up. As Jason said, now screw the cap-screw into the crankshaft leaving a gap between the underside of the screw's head and the face of the flywheel. Lightly tap or press on the head of the screw, forcing the crankshaft down towards the bench. Once the screw head bottoms against the flywheel, remove it and check if the flywheel is free. If not, re-install the screw, leaving a gap, and press it down a little further. Make sure the screw is long enough that it screws well into the crankshaft while still leaving a gap. If it only turns in a couple of turns you may damage the threads

Thanks so much for your help, I was able to disassemble and clean.
"That looks like an early Buick Riviera flywheel.
Quite rare.
If it is, it should have a stock Babe Bee crankshaft."
Mudhen,
Please explain, engine has the following:
'6' on the cylinder
W shaped filament in head
'Thimble Drome' on tank
I replaced the NV, the one installed was damaged.

Re: Help with Disassembly
Looks like you have what Mudhen suggested.
All the #6 signifies is it does not have SPI, did it have a muffler at one time?
The W element could just signify it was replaced in the early 70’s.

This was a recent ebay purchase. I wanted the engine with the screen, so the other ,to me, was a bonus.
I don't know anything about this type, so any info would be appreciated.

Re: Help with Disassembly
Unless my tired eyes are fooling me that looks like a large splined crankshaft.

The engine with the mount came from a vehicle model.

I thought it was an early issue was because in his first picture I didn't see a cylinder riser and the outer flywheel looked anodized, though faded.
Maybe my it's my "tired eyes."
Here's a pic of an initial issue which has a standard Bee crank.
Not understanding the terms you are using,(i.e. cylinder riser), please explain.
I want to learn about these motors, any info would be great.
