Help needed please. Front crank pulley won’t budge

[jaymdee]

Am trying to change the cambelt among other things and the pulley nut is off but the pulley won’t pull off the crank. 

We’ve tried using a puller and all that’s happened is the threads inside one of the puller bolt holes have stripped.

Any suggestions before I look into whether I can tap a hellicoil in there?

on another forum someone suggested getting behind the pulley with a nut on the puller bolts. Is that possible, as it looks like the plastic housing and aux belt tensioner are in the way.

thanks

Jon

Update.

With help from a mate who builds motorbike race engines we helicoiled the stripped thread (was only one in the end) and with a little measured encouragement with a blow torch (not too much and applied in several stages) we’ve got the pulley off using the puller. Hopefully no detrimental effect to crank and oil seals etc. You can see rust on the crank which I’ll need to sort out before the new pulley goes back on, so probably why it was such a pig to remove the old one.
