Need Help: Wisconsin BKND Clutch Removal

[WickedWisconsin]

Hello, Lawnmower Forum! I have recently run into a dilemma while dismantling a Wisconsin BKND from an older Whiteman DB60 Power Buggy to overhaul. The clutch which resides on the engine proves frustrating to remove and the design appears quite unconventional. There is no keyway in the crankshaft, so I presume it is threaded on, however, it is seized and refuses to budge(even with the application of heat). After several attempts at research, it has come to my attention that there is little information on this particular centrifugal clutch, which I believe it a Salsbury Model 600. If anyone is able to provide more information on the clutch and its removal, or advice of any sort, it would be greatly appreciated. Thanks!

I suspect it is a keyed shaft, and could possible be a taper keyed shaft. It is most likely just very stuck on the crankshaft. I would hope it is a taper shaft and not a straight shaft. Straight shaft may be close to impossible to break the corrosion bond without damaging the clutch.

This website might be of some help, as they know their older engines and this looks like your setup. https://www.smokstak.com/forum/showthread.php?t=47284.
