Post subject:	How Much Pressure?
OK well my dad and I have been working (procrastinating) on the heinz for about a month now and we are replacing the clutch ....yay ........NOT!! This job was made even more difficult by not having a flywheel puller so we went down to superscabs like we do and got one ........ got home and I say to dad "this won't work it is too small" ..to which he replys "CRAP of course it will, give me a go!" so away he goes and it dont work so ...... now we go and make one ......all well and good but (and this is a big but) it doesn't want to come off the taper. Which brings me back to my question how much pressure should there be to take one of these suckers off? HELP ME PLEASE!!! Pat

Sometimes it takes heaps.. My puller is 20mm thick plate, 1" UNF Grade 8 bolt in it, Grade 8 nut `stick welded' to plate. I've had it over 35 years now. The puller plate has a 3/4" thick bar `handle' welded out the side so I can put 3' of pipe on it. Ditto the 1-1/2" socket and bar, I put 3' of pipe on that. Threads are oiled to prevent seizing. And ,sometimes, it's taken all my strength to get them off with this monster. OK so I'm not as strong as I was.. My point is yeah, they can be bloody tight. Get thee a bigass puller..!

Ive heard of some people using an oxy on the flywheel to heat it up, then get stuck into it with a puller.....

dont start to wack it with a hammer or blunt object...you can put hairline cracks in it, or warp it, or just fook it up. Also, with a puller.....just be carefull, because when she finally lets go, it can fly off and drop on the floor all in a flash. I did 2 recently and the secong 'popped' off and hit the deck...inches from my foot! Lucky I wasn't wearing my 'GAFMO' safety boots!!

As the good Dr indicated - remember the lever principle - the longer the lever the less force required

As you will tighten it to correct Tourque then hit it with hammer and it will go another 1/4 Turn I usually do this a number of time until it will not turn any more and I have not had any trouble with my Fly Wheel or any other one that we have done like that. Some have been running for over 15 years straight.

The fly wheel Puller...I have used Dr one 4 time now and she works a wonder... Couple of hints. Bag of rag's or a Dooner under the fly wheel so hopfully it will land on it Stand to the side with the long bar on the puller so it does not hit you (also move anything valuble in firing rang) If the Motor is out of the engine bay, Use a boat and trailor on top of it will keep it stead Ay Kev other wise lay it down on rag's with all the attachment off and some one standing on the box

It's a good idea to sit something in the end of the crank to push on, so you don't damage its centre or the threads inside.. I use a 5/8" bolt cut 1/2" long, with the threads turned off. Or a 5/8" nut will do.
