Fitting this back tonight. It seems an extremely tight fit over the crankshaft end. Is it normally this tight? I see reference to 'drifting' it on, mid drifting or quite severe?? Any tips / advice welcome. Cheers.

According to the manual, it should have a maximum of 0.0005" interference fit.
It can be as loose as 0.0003" clearance, and still be OK.
Measure it. If it's too tight,you could polish the bore with a roll of emery paper to loosen it some.

Thanks. NEVER do work at night after a busy days work. Took your good advice and heated it up, picked it up with mole grips on the collar, it slipped on a treat. As it was cooling and gripping the crankshaft i looked at and saw I had put it on the wrong way round, idiot.
So now I have the flat side hard up against the case, no room for a puller, tried heating it up to pull off but the crank acts as a heat sink now so no budge!

I think I am faced with setting up the dremel, cutting through by the slot so I work towards the woodruff key.

I can't think of any other fix unless you guys can

Can you use a gas torch with narrow flame to heat directly on the hub to quickly heat it without the crankshaft sucking away the heat?.
Good luck.

James.

HOW FAR TOGETHER IS THE MOTOR IF ITS JUST THE CASES TOGETHER AND NO BARRELS SEPERATE THE CASES SUPPORT THE TIMING SIDE CASE ON BLOCKS OF WOOD PUT SOMETHING SOFT UNDER THE CRANK TO CATCH IT GET A GOOD BLOW TORCH HEAT THE PINION QUICKLY AND TAP THE END OF THE CRANK THROUGH THE PINION USE A PIECE OF ALLOY TO PROTECT THE END OF THE CRANK

All done, my amazing engineer Roger at Full Bore Watford, welded a nut to a washer, the washer to a tube, then the tube to the offending pinion. He effectively created a 'puller' and off she came. I will try to upload a pic next.
