oil is useless. How much if any heat can be applied where to get it loose? Its only been
on two years and was installed with neversieze so it shouldnt be such a pain.
Thanks in advance

Loosen the flyweel nut and apply WD40 (or similar) to shaft - leave overnight. Use a correct puller (make or buy) threaded into the (usually) three holes in the flywheel. With the centre bolt torqued up with as much as you can muster with a typical standard length socket wrench and holding the flywheel with a strap wrench to stop rotation, hit the centre bolt to jar the taper free. May need several blows, but don't overdo it! I would consider that heat is the last resort, as the risk of damage is high. By the way, heating the flywheel enlarges the centre hole because the whole flywheel becomes slightly larger, including the centre hole.
You'd think that after 20 years the WD40 may have loosened it up. Personally, I'd go for PB B'laster
instead of WD40.
