How to a weld the pulley on the shaft?

I am lucky with my solution.

But only to know how it works: How to change the shaft? Unmount the engine and disassemble the whole gearbox?

Thanx, seems to be easier than I thought. Clargo Garage made lots of helpful videos for XV1700!

Some weeks ago I welded the pulley and was successful with all your advice. I made some longer trips and the pulley is running like a charme.

Glad to hear this but you should still consider looking for the parts for a proper repair to have on hand just incase lol.

What did you decide?

Yes Duke, the way you and Dave suggest will surely only get you home, if the shaft wasn't so mangled I would agree. I think the OP is considering epoxy again, Lol.

MikeyC, I agree new parts is the proper way. I've seen some pretty amazing stuff done however with modern tech/chemicals so given the right combination it might work in some circumstances.

[MikeyC]

That is what the epoxy was for. Previous owner filled with epoxy and the epoxy had come out. I have heard of that being done with JB weld but the proper way would be to replace shaft and pulley.

Hello! Has the JB Weld cured yet? lol.

do it once do it right, both are toast from the pics .

If your planning on welding, then I fully agree with Dave.
With the nut torqued tight, it will keep the shaft tight against the inner races on the bearings.
I, myself would not weld my pulley, unless it was to get me home.

KFallsRider asked "Are you getting this JoeX ?"

I hope so .... tomorrow I will make a new video and explain what I understood.

What did you decide?

I agree that heat transfer through the shaft is a problem. That is why I prefer stick welding in this situation. The heat is concentrated and if cooled immediately it won’t have time to migrate up the shaft especially with the pulley acting as a heat sink and absorbing a lot of the heat.

Good point .... I changed the title.
