Holy sprocket nut Batman!

I tried taking it off last night, but the only socket I have that even remotely fits it is a 1 1/8" deep well six point. But it fits a little loose and I can tell this is going to take a buttload of torque to get it off, and the last thing I want to do is round the nut off.
So, will a 1 1/16" socket fit on the nut, or do I have to buy a metric socket? And that would be a 27mm socket, right?
Or, does the front sprocket shaft happen to have left hand threads, (that would help explain things)? :blush:

I was using a peice of 1/4" drill bit shank to jam the sprocket and chain to the block.
I pulled, I pulled, I pulled harder, even harder, and just about when I started wondering if I've ever put that old breaker bar through that much stress, "SNAP!!" went the drill bit.
I doused it with Kroil, drank a beer and called it a night, and decided to attack it tomorrow with better tools. Right size socket and a 4 foot piece of pipe, I should be good to go. And I think I can get a piece of 5/16" drill bit shank through the chain. If it snaps that, not sure what I'll do. I guess break down and buy an air impact wrench.

When I removed my front sprocket, it was impossible even w/the correct size socket and a long breaker bar(pipe). I ended up carefully using my dremel to cut the old nut off and bought a new one.

If I can cut deep enough, I should be able to crack it with a chisel without damaging the shaft threads, but I don't want to beat on the shaft bearing either. Maybe I can get my wife to hold a five lb hammer head on the opposite side of the nut while I tap it with a chisel.
Does Z1 sell them, or is that a dealer item?

Edit: It is right hand thread, not left, if I remember correctly... If you are going to buy an impact wrench, I would look at the electric ones. I bought a cheap air wrench from Northern Hydraulics (like Harbor Freight) years ago, but my air compressor couldn't put out enough air to keep up with it.:S

Hi RR,Thanks Ron, great idea. I may end up doing that. Did you use one of them little Dremel cutoff wheels, or a router bit? I have some router bits that might cut it.
If I can cut deep enough, I should be able to crack it with a chisel without damaging the shaft threads, but I don't want to beat on the shaft bearing either. Maybe I can get my wife to hold a five lb hammer head on the opposite side of the nut while I tap it with a chisel.

I used a cutting wheel, I also didn't cut all the way through the nut. Instead, I cut the nut in 3 places as far as I could w/o hitting the spindle. I then used a regular hammer and chisle to "break" the nut off the spindle. I'm sure you could get it from Z1 but I got mine from "motorcycle-parts.com"...I think:)
good luck
Ron
Nev, I wish I could have removed the nut w/o cutting. I don't know why mine was rusted so bad, I really did try everything, except an air wrench(no access), including an impact wrench. It just was not comming off.

If that don't get it tonight, then tomorrow I'll swing by Harbor Freight and pick up one of these: www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=93866
Then if that don't do it, I'll go ahead and cut it off.
Thanks guys.

kind of ironic, the locking washer on mine died and the nut fell off while riding, was not fun at all

When I saw "SNAP" I thought the chain or output shaft broke...
To remove the nut on my bike, I put the bike in gear and had my 180lb son stand on the rear brake. Then I went at it with a breaker bar, pipe and 1-1/16 socket.
