Flywheel nut 2 1/8" on 88T2?
 

I have the socket, it seems to fit well. Man is that sucker tough to break.... I have a 4' bar, and the flywheel stop bar also. Is this thing really English, or is there another metric size I should be using?

My impact only does 180ft/lbs.....

Thanks

We use the same size socket as you have at the shop. Try heating the nut to help release the locktite. Also turn up the regulator on your compressor. We use 150psi in the shop. If all else fails and you don't want to take it to the dealer or a speciality shop, when I was first taught basic rotaries in Hawaii, Larry Nova showed me the effective but nasty way to remove the nut when you don't have the right tools. Heat the nut, then use a dull chisel, so it doesn't cut through the nut, holding it with some vice grips(so you don't hit your hand) and beat the nut off. It is right hand threat. Not pretty, but effective!! Rob

Yup. That's what I did when the nut wouldn't budge. I got a torch and heated the nut. Got a breaker bar and it came right off.

I used a 4' extension on the breaker bar to get mine off, and it took everything I could pull (and I'm a big guy too). That 180ft/lb impact wrench ain't going to hack it, that sucker is supposed to be torqued to well over 200 ft/lbs (I think 280 to 320)

Ok, so I tried the heat last night. Still with a 4' breaker bar, wouldn't budge. Reverse threaded?? (or right hand thread) I though-- didn't get to post this until now.

I should have read the response more closely:

I'll try that tonight :ar:

Damnit, now I'm confused. Is this nut regularly threaded, or reverse threaded?

That's what I'm wondering!!! WTF??? I can't budge it either way....

Hi Ho, Hi Ho, it's off to Farm and Fleet I go...
For an Air Compressor that I shoulda bought a year ago,

I was just at sears and they have a phat impact wrench that will do 600 ft lbs in reverse for $130. I'm gonna get me one and bet the shit out of that nut...

Have someone hold the socket firmly against the nut. Get you 20lb sledge hammer out, and firmly strike the 4ft bar. That and the fact that you have already heated the nut, should guarantee that the nut will come off. Its righty tighty, lefty loosy. 20lb sledge cost maybe 20bucks. A really good impact cost a bunch more. How many times are you going to use that high dollar impact wrench?

Well, actually a fair amount. I use my electric quite a bit, although it's very convienient. I will string a air line into the garage, and keep the compressor in the basement so atleast it will be accessible in both places. I do see that Milwaukee makes a 300ft/lbs electric for $170, they also have a 3/4" electric with a higher (I thought 600ft/lbs) rating. Very tempting....

So Hailers, are you saying the nut is a standard thread-- turn counter-clockwise to loosen? Assuming you are looking at the flywheel.

Thanks everyone, I knew I could count on you all!:)

Yes. Counter clockwise. If you use an impact that much, go buy a good one. I only have trouble with two items on that darn car. One is the flywheel nut and the other the rear hub nutz. The last two engines I tore apart, I used a Craftsman(so I could return it if I broke it) 3/4 breakover and with one hand holding the socket on the nut, struck the end of the breakover bar with a 20lb sledge hammer. Hit it twice if memory serves. The shock of a 20lb sledge hammer seems to cower the nut into submission. Go with the impact since you use it that much. Have fun. P.S. I was just kidding about abusing a Craftsman breakover and then returning it for another. Just joking. Would never do that. I'm innocent. P.S. I did break a 1/2 inch breakover bar taking the nut off on one car, though. Here's a post I made on the impact subject sometime ago https://www.rx7club.com/vforums/show...threadid=13973

i have been lucky with a chisel and/or using the floor jack's handle as an extension to the breaker bar. have ur buddy put his foot (off couse with his shoes on) on the socket to prevent it from slipping while trying to loosen the nut. to remove is counter clockwise.

Air Compressor Pkg
 

In case anyone else is interested, Home Depot has a 5 hp Cambell Hausfield compressor with a whole kit of tools (die grinder, 500ft/lb 1/2" impact, cheap spray gun, and a bunch of other stuff) for $260. It's only offered during the Holidays the guy said, and since a 300 ft/lb electric was $180 (DeWalt), it was too good to pass up.

BTW, it got the nut off too :D

Now, if I could just pull the friggin' flywheel off...... LOL

I've used a four ft piece of angle iron with a couple of holes to match where the pressure plate attaches, bolted it on and hit the ends of the ANGLE IRON with the 20lb sledge. Regular hammer works just as well. I've also used two crowbars on each side. Gotta watch and make sure I don't break a piece of the rear housing. Gotta go. I hear there's a sale at HOME DEPOT! Thank you.

Why not get a Torque Multiplier wrench? That's what I did when I had my engine done up. Makes it easier to torque everything to spec as well....just a thought.
