Anyone seen one of these before??

This is a pulley on the crankshaft of a J.A.P. 2a that Im restoring at the moment.

I'll be buggered if I can get it off!

You can see there are two holes in the outside pulley that line up exactly with the holes on the inner bit - I have stuck a screwdriver through them all to show it goes all the way through - there doesn't seem to be anything in there that undoes, or pushes or anything...

There are three circular things on the front of the inner section of the pulley - one in particular looks like it might move - ie: screw out? Push in? or something.

Any suggestions??

I suspect it will be a trivial exercise for someone who knows how they work


Cheers
