Hit the back side(NOT the ring gear) of it with a hammer. Or use a heavy duty puller.

Get a BFH(big f'n hammer),and hit the outside edge of the flywheel near the ring gear hard.This will rock the flywheel to one side,and it will pop off the eccentric shaft.Ihave used this method several times,and it has not failed me yet.A word to the wis though is put the nut back on a few threads just to catch the heavy flywheel before it comes off and hits your fleshy bits.

hard, with a hammer. It should only take a couple good hits and it'll just pop off, leave the flywheel nut on a little bit so the flywheel doesn't just fall on the floor.

Easy just spray some pb blaster on it and it'll lift right off after a minute or two... If not that then put a big gawd damn screw driver under it and hit the handel with a hammer and it'll pry right off. if not go get a man to take it off...

I rented a puller fromAutoZone. Installed it and tightened it down, then hit the flywheel with a hammer...popped right off.

Torque spec is 400-500 N-m for the metric members. Use locktite too.

Put it on with the impact and let the impact hammer away for a while after it stops tightening. Use locktite liberally.

For gods sake don't use too much loctite. I tried to get a flywheel nut off before where they used too much loctite and it was hell. I actually bent a 3 foot long cheater bar trying to get it off. You don't really even need loctite. There is soo much torque on the nut its not going to come off, assuming its torqued right. I think the number is 380 lb ft.

Many impacts do not provide enough total torque. I have no idea what brand you have or the capabilities of your compressor. A torque wrench is the best way. I recommend locktite if you have no idea on the final torque. The locktite bond is easily broken with heat when it comes time to remove.

Back to the topic, two-three hits on it with the right hammer should take it off!

Yea, I just tightened mine with the impact wrench, but I wouldn't recommend it unless you know how much torque it's hitting it with. After I finished, I bought a 3/4" drive torque wrench from Harbor Freight that goes up to 300 ft. lbs. Very reasonable...$70: http://www.harborfreight.com/cpi/cta...Itemnumber=808. I have no idea how accurate it is, but it must be better than guessing with an impact wrench.

Well my impact would own that nut and then some, haha Snap-on 700 ft/lbs of torque. But on a different note, torquing to that large of a torque spec is going to be fricking nuts with a torque wrench...

Reminds me of good times with diff crush sleeves...
