Anybody know what model this flywheel holder is for? Bought it from a shop, 20+ years ago but isn't any use for series 3 so sat in the garage since.

Looks like the one I have and so don't know why you say no use for a series 3.

It can be used on both flywheels with 2 or 3 holes/slots because it only uses 1 hole.

When I tried it on my old SX, as soon as you got a bit of torque on it, it twisted itself out. Unlike the 2 prong one I bought later, which locked itself in, as it was tightened.
I have found a small number stamped on it which looks like 58031 so think it is an original tool.

Sorry that's 58013

The one prong type of flywheel holder is 'useable' as other members comment, but it does not hold the flywheel so securely as other types, in my experience.

The two or three prong type are far more user friendly.

However, if the prong is modified by grinding in a recess on it's edges to register in the slot, it cannot so easily force it's way out in use. A 'U' shape on both sides (close to the ring portion, leaving the prong uncut @ it's extreme ends) is all that is required to prevent slipping. A Dremel type tool is ideal for creating the necessary cutouts.

Of course, such a simple modification can easily be done to benefit any flywheel holding tool, whether there are one, two or three prongs.

I hope that helps.....
