109 tooth flywheel 200mm cluth on a 40 horse

[Seb67]

Can a 109 tooth / 200mm European style flywheel bolt up to a stock 40hp Crankshaft? In effect letting me use a larger 200mm clutch for my old 40hp motor?

Thank you....

yes.....if your 40 hoss is 12 volt, use a 6 volt starter and a suitable bushing.

I thought 109 tooth is 6 volt?

Is the 109 tooth flywheel for a later O-ringed crankshaft? If it is, it won't fit the 40 horse crank without machining.

In the old days.....LOL......a "6 volt, 200mm flywheel" was a colloquial term given to a highbred flywheel, allowing the use of 40 hoss crank, with the benefit of a 200mm clutch. A "O" ring, 200mm flywheel is just a "O" ring 200mm flywheel. Also, the 6 volt 200mm flywheel would fit inside of a swing-axle 6 volt trans bell housing without machine werk.

Yeah, I read those books too. Sounds like you just need to use a non-O ring, 109-tooth 200 mm flywheel. Why "machine" anything? Besides screwing up rare flywheels.
