Sled clutch mod?

[birddog1148]

I just won a small taper Salsbury Primary drive clutch on Ebay. My intention is to have it bored and broach cut for a 1 in shaft. Has anyone ever done this or heared of it?

Probably won't be enough meat to bore it out.

Well I was just wondering because the big end (25mm) is just a froghair off an inch.

25mm. figures out to 0.9842519685050001". Seems doable to me. I'm not sure of the sizing diferences in the keys but that could probably be worked out too.

I dont think the tapered sled clutches have keys do they? I have access to a Lathe and the tools to broach the keyway. I am going to use it on a 13HP clone.

Got me, I live in the desert and never even checked out a snow mobile up close. But I'd think they'd need some way to lock the driver to the pto besides just a taper.

Nope all the drivers i've seen have just been taper locked, most of the ones i've seen wouldnt really have enough meat to bore it out, but hey its worth a try. You're also going to have to change the spring and weights inside the clutch so it engages properly in the RPM range your clone has.

Yea, i figured that

You can extend the adapter shaft if needed, and add a bearing to the outer end.
