Flywheel Holding Tool

[dan williams]

Working on a friend's bike I was concerned his flywheel key may have sheared so I removed the flywheel (key was fine) now how to re-install? Holding the bike in gear with the back brake locked is not an option. Not only can you not get enough torque on the nut you risk damaging the crank by applying twisting force to it.

After scheming various machined and welded special tools I realized I was over thinking it.

$6 worth of bar stock, four holes, three bolts, a wing nut, couple of washers and one hacksaw cut later...Voila! The Beta flywheel holding tool. Works like a charm.

That's amazing...it's just like the one I have at home,only mine fits Shercos..funny that.

Caution, if you're gonna make one for a Beta I think the bolt thread depth is crucial , I seem to remember someone wrecking their stator with a home-made holder.

Nice work Dan , But in a pinch can't a bit of small rope carefully inserted into the plug hole (right before TDC.) perform the same task ?

Or are beta's that unique ?

Yup the washers keep the bolts from digging the coils as well as making it all line up.

The rope in the cylinder trick is OK I suppose but it still applys twisting torque to one side of the crank plus it adds possible contaminents to the combustion chamber.

Nice job on the holder Dan. You obviously have no need now, but I have a Kawasaki adjustable flywheel holder that works on many flywheels. Not sure if they still offer them, but it was low cost and great quality.
