Recalcitrant Flywheel
Discussion
Hi, I started the day with the false imprecation that taking the flywheel off of a SBC and replacing the G50 adaptor plate and starter with an adaptor and starter for my 996 box would be easy, not so!!
Having tried various pullers, shovers and levers it still remains in place, anyone got any good ideas....please

^ I noticed that to, impressive isn't it but he still can't get his flywheel off, lol. Needs a mechanic. Seriously folks, it's easy. Suspend engine vertically in the air by the flywheel. Place a soft pillow on floor under the engine. Get the gorilla on the tvr minder thread to hit crank with a hammer, preferably a big hammer. Jobs a good un, watch out in case the engine does a little bounce
Well I've tried again and still no movement, I've reset the flywheel and started again as suggested, I tried various pullers, I've heated it, sworn at it ...... so it must be time for Boosteds suggestion, soft pillows are to hand!!! One final thought is there a special puller I should be using and where is the ideal location for the puller?

David, I made mine own puller when I had to send that very engine away to be rebuilt.
IIRC, it was a piece of 2" box iron (just a bit longer than the width of the flywheel), with a 1" pipe socket welded at the centre. I then drilled two holes in each end of the box iron to line up with two of the threaded holes on the flywheel.
It was a case of of winding the two bolts through the box iron and into the flywheel.
Does that make sense?
Don't think I have it anymore though, did not need it again after that.

Definately don't try my suggestion! You'll end up with a bent crank if the engine drops to the floor.Thwarted of Winterslow
The fact that you're able to reset the flywheel indicates that it will move. I'm sure it's just a case of pulling it off while keeping it straight if you see what I mean. As others have said, maybe there's dirt on the crank or a slight burr that needs rubbing down.
Where is Winterslow?
The problem with heating the flywheel is that you only have a limited amount of time before the thermal transfer to the shaft negates any benefits made in metal expansion, once the shaft starts to expand as well you are back between a rock and a hard place.
Try heating the flywheel as normal to expand it, (clever bit) then target the shaft a few mm out from the flywheel with liquid propane, the type you fill lighters with, just press the nozzle onto the shaft and let it have it, the evaporating propane will start to contract the shaft. You now have twice the amount of metal movement albeit in opposite directions.
Hope this helps

Do you have any brake cleaner (aerosol type)? I'd nip the flywheel back up and give the end of the crank/ flywheel boss a good clean with it, you might be able to see the problem or it may resolve it. Clutch dust gets everywhere and just like brake dust, can cause lots of minor seizures of surrounding parts. Good luck.
