IT WORKED!!!! yes the flywheel is now free from the crank - excellent piece of equipment - many thanks for all your help.
Well done I told you it wouldn't let you down, did it come off with a bang or a whimper?
Funny I didn't think it was going work - I tightened it all up and it didn't move - so I hit the end a few times, re-tightened it as much as I could, but it still didn't move - so I was about to give up and went for a cuppa to consider my options.
About 1/2 hour later, I went back into the garage and give it another go - hit it again and re-tightened it, and it just fell off - I actually thought that I had pulled the threads out of the puller or something because there was not bang or noise at all - the bar I was using just turned and become all loose.
