Back in Feb. I destroyed my clutch via a nasty 3rd to 2nd down shift. Yea I know pretty dumb, Im more accustom to 2nd gen. Removing the tranny was easy. clutch and pressure plate removed, no problem. The flywheel looks bad lots of heat stress. It appears to be one huge nut in the middle. do I need a special puller. I know it needs to be resurfaced if its still good. Ive seen lightened steel flywheels for but damn there not cheap. Can a competant machienest lghten a stock unit whithout messing up the ballance. any advise is good advise,Thanks https://www.nopistons.com/forums/pub...1047683473.gif

You don't need a special puller, if you can get the nut loose (52mm or 2 1/8" socket and a BIG impact wrench), all you do is tap around the edge of the flywheel with a hammer >not hard< but just so the flywheel rings like a bell, it'll pretty much pop right off.

Hey thanks for the info man its greatly appreaciated. I measured the nut and thought it was 2 1/4 but I probably measured wrong. Can I get away with using a breaker bar.

make sure before you try to pop it off with the hammer you put the nut back on a couple threads, you dont want the flywheel falling on you

No, I dont whant to dropp that on my head. Can I get some feed back on weather or not its posible to lighten a stock flywheel via a machinest. https://www.nopistons.com/forums/pub...DIR#>/wink.png

the answer is yes, but i'm not sure you can take enough off to make a difference

54mm or 2 1/8". I'm going to get a 54mm six point impact socket soon. https://www.nopistons.com/forums/pub...IR#>/smile.png

The problem with having a machinist lighten the stock flywheel is you are going to have him remove metal that is used to dissapate heat. The aftermarket lightened flywheels are made out of different material, it isn't the same metal just less of it. So you start removing a lot of it and you are going to have a lot of extra heat in area where you don't want it.



I wouldn't waste your time or money.

Thanks for the info, I guess i wont try to lighten it then.

54mm. Of course. https://www.nopistons.com/forums/pub...1047683664.gif

Lightening stock flywheels will only cause vibration. You would be trading quickness for high and maybe even normal speeds. Try to keep a sharp eye out for a used one before you get it back together, You might find one in time to put it in. Im not sure if they keep the after market parts but you might try :

This is important, so I'm quoting it to reiterate. https://www.nopistons.com/forums/pub...DIR#>/wink.png

That was NOT the case when I pulled my flywheel. It was REALLY stuck on there. I had a 1'' thick steel puller, bent the sh*t out of it. I tried hitting it off with a hammer, no f*cking way was that going to work, I tried for hours. Then I had a good puller made, 2-1/2'' thick steel, that finally got it off, but even with that it took a while, lots of cranking down on the puller, then hitting with a hammer, crank on the puller some more, hit with a hammer again.....but it eventually came off.

Yeah it won't work quite all the time but it is certainly the easiest way if it does.

Hopefully I wont need a puller. I'll try the impact gun first thanks for the insight.
