Whati s this tool?
 

Last weekend someone gave me this. I think it's some sort of pulley-holding tool, but I have no idea what the original application would have been.

looks like a MC rear hub tool for tightening the chain. Could also be an old shock adjusting tool.

to use when changing a garbage disposal?

Shock adjuster for a motorcycle.

Spanner wrench used to loosen or tighten a specific thin nut size, like Varmint said

Coil over shock adjuster. Bike or car.

It is a spanner. A little smaller than the one in a 911 toolkit

This.

Hook Spanner

Technically speaking, if it’s for a motorcycle, it would actually rotate the threaded collars to adjust the spring preload on a rear shock.

I have one sort of looks like that for the spring perches on the Miata

In Porsche speak that tool holds the fan while you undo the nut. Except the handle looks short too be really useful. Also used to turn a spring perch on a coil over shock with the spring still inserted.

I have a half dozen of them.

You slip the cylindrical lug nut doo dad over it to increase leverage

+1 on the 911 fan belt tool.

Or a Coilover adjustment tool but the radius looks too big.

W/o being designed for a specific use, it's just a spanner wrench. Many are adjustable.

On a Norton commando from the seventies, that tool comes in the kit and it's used to make sure the large exhaust nut at the head stays tight, otherwise you strip the treads in the head and then you're f****d. Steel nuts, aluminum head.
