A tale about a failed Royal Enfield Himalayan crank shaft key and how a piece of the number plate was used to solve the problem.

Oh yeah............. love it ! :thumbup1:

Greetings NightAlp

Wonderfully ingenious :clap: - right up there with cutting a car head gasket out of a door panel and epoxy glueing friction material chiseled from brake pads onto a burnt out clutch (again on a car).

One question though - I was always taught that it was the friction fit in the taper that held stuff like the flywheel in the video in place. The woodruff key was only there to locate it, not to stop it going round. You'd lap the flywheel onto the shaft with e.g. fine valve grinding paste until the tapers were a matched pair, fit the key so it was in the correct alignment and then do up the nut to "jam" the two components together. Is that not how the Enfield flywheel is held on the shaft?

Yes, that's exactly how it works. But the nut they have given is a normal nut, not a lock nut. So it tends to get loose over time which shears the key.

Also, this is new bike and has only undergone regular service. So it the nut wasn't torqued properly, that happened at the Royal Enfield factory.
