stupid sprocket.. I know this sounds stupid and it's been covered before...but what are you guys doing to get that front sprocket off? I put the breaker bar with pipe on there and nothing....heated it alittle..nothing.....impact...nothing. Is it a reverse thred nut? I done this on my old zx11 but it wasnt as hard to get off as this one.

Well, actually this is not a stupid post.
We gave Outsiders zx-12 everything we had. My impact wrench, my buddies impact wrench.
Actually bent a wrench trying to loosen it up with a 4 ft. cheater bar,
He drag races so I don't know if that was the culprit but that bitch was on there and tight.
He finally got it off at his Dad's shop with an industrial compressor and (I believe) a 3/4" impact that they use for stuff like removing lug nuts from EARTHMOVERS!

There are lots of older, weak impact wrenches out there, and many people have their air set at the typical "recommended" pressure of 90psi. It's a combination that doesn't work well for really tight stuff. Get youself (or borrow) an IR Thunder Gun, Harbor Freight Earthquake, or similar, set your air at 125-150psi, and it should spin right off with little effort.

Impact should come right off. make sure the compressor is charged and the air gun is set to the highest setting if settings are available.

Snap-On top of the line impact gun and my compressor was maxed out at 175 psi. It's not a small compressor either.
Dude, I could have spun the space shuttle into the air with everything I was throwing at it. We even heated it up as much as we dared without ruining the seal.
I have never encountered a bolt I couldn't get loose or break until this one.
I shit you not and Outsider can verify. I gave up because I was afraid we were going to break the countershaft. Seriously.
His Dad hit it at the shop with the big gun and it came right off but that bitch was on there and tight.

you guys are bending the lockwasher tab flat first aren't you?
Bent the lock washer tab flat, 2 ft johnson bar, rear brake applied a spun like nuthin.
If its reallt tight you can heat the nut a little, be sure not to burn the counter shaft seal though.
They use red locking compound on the threads from factory.
Never needed heat for mine.

Worst one we ever loosened was the clutch hub nut on my friends ZX11. 150 PSI and 2 minutes of solid "hammering" with the impact wrench before it finally came loose..
posted July 30, 2006 09:25 PM
That one needed some heat then.
That hanmmering is really hard on bearings,
The balls spin backaand forth with the hammering effect, and get micro surface indents.
Then they wear out prematurely.
Seen guys take out crank bearings on snowmobiles from that.

I couldnt get mine off. I have a Matco impact with 150 psi going to that thing. I have a matco 3 ft breaker bar with a 2 ft peice of pipe on it and nothing. I done the unthinkable and stripped the center part of the nut. Now i have to see if i can find a socket the size of the larger part of the nut. I put alittle bit of heat on it too......nothing. I gave up...i was hot,tired and pissed off...i put the bike back together and went for a ride.

Ok guys i need some help here. You wouldnt think taking off this front sprocket would be such a pain in the ass. I totally destroyed the nut lastnight. I used 2 different impacts a huge breaker bar and even heated it alittle and nothing. I know you guys said it took alot to get it off so heres what i'm going to do. I have a buddy who works at a semi junkyard, i'm going to take it to him and see if he has a socket big enough to fit on the largest part of the nut. This is the only spot on the nut not mangled and stripped. Now i'm assuming the nut spins counterclockwise like the one on my 11? I'm going to be really pissed if i have been trying to tighten it this whole time if it was reverse threads. Is there anything else i need to do before i hit it with the inch impact? I think this is going to be a one shot deal. I keep looking down the center of the nut...that looks like a allen screw but it's not......what am i missing here?

I'm not the best motorcycle mechanic in the world but this is stupid. I have turned every wrench on that bike and that little sprocket is getting the best of me.

I take the clutch hub nut off with a 18inch breaker bar and a 2ft. pipe on the end...
I use a 18 inch 1/2 extension socket in the swingarm axle and rest the OEM Kawasaki clutch hub tool on it and put the pressure on the pipe and it comes loose pretty easy...By the way I do it by myself !!!
I tighten the clutch hub nut the same way...I do it like this because I too used the impact and it ruined the hub nut and was unusable...I was cursing like a MoFo!!!

I just had the wife hold the rear brake - 1/2 Snap On gun, it took a couple of pops
but came rite off. For those of you that got it with a breaker bar "good job"
Those things are on there pretty tight.

Based on the counter-clockwise rotational direction of the drive sprocket, I wouldn't expect that nut to be reverse-threaded.
I'm also confident that if it was reverse-threaded, that it would have been pointed out in this thread already.
Here's another thought for those who have found their drive sprocket nut to be extremely tight... is it possible that it's "self-tightening" even more with hard clutching or launches? Maybe the nut gets really tight on bikes who's owners drag race or wheelie more than others? Just a theory...

no , it is not reverse, or left handed thread.
it will not get tighter, as the lock washer , which bends over a flat on the nut, and slips into the splines of the shaft prevents unintentional tightening, or loosening of the nut.

ok guys i got it off!!! Man was that a bitch. I eventually had to take a dremel and cut a slit out of the nut and use a hammer and chisel to loosen it up. It took about a half hour but its off. Damn that was the hardest thing to do on my bike so far. Can anybody give me a part # so i can order one from a dealer...or does anybody have a line on one so i can get it by wednesday.

It's not a small compressor either.
