PSA: Stop going crazy with the countershaft sprocket nuts already! - October 29, 2013, 08:52 AM



Look, countershaft sprockets are not permanent installations on motorcycles so stop torquing the living daylights out of the nuts and for the love of humanity, STOP USING HI-TEMP THREAD LOCK!!!

When heat and industrial-strength tools are not sufficient to break loose a countershaft sprocket nut on a modern motorcycle, it means some dipshit overtightened the nut and coated the threads with hi-temp thread lock. But it is not necessary. Please, please, please do these things when installing front sprockets.


7 easy steps to installing a front sprocket on your motorcycle so that it is not a permanent fixture:

1.) Educate yourself on what you're about to do by consulting your service manual.

2.) Tighten to specified torque, don't just hammer on it for 5 minutes with an impact gun.

3.) Don't use hi-temp (red) thread lock. It's not necessary. If you'e freaking out about it coming loose, then put some regular blue stuff on the threads.

4.) Don't use hi-temp (red) thread lock.

5.) Use the cute little toothed washer thingy to hold the nut from loosening by folding part of it down onto the nut. It's an adequate safeguard.

6.) Don't use hi-temp (red) thread lock.

7.) Don't overtighten or use hi-temp (red) thread lock.


Are we clear? Thanks.

not yet. I have to get a different socket. The impact socket I have is not deep enough, and I'm worried that the regular socket (multi-point) is going to eventually round off the nut.

This one may surpass the one on my old bandit as worst ever. I keep looking to see if someone spot-welded it on.

What's it on? It's not a LH thread is it...

Well, if you need more firepower the compressor is yours to borrow. BTW, I'm doing the chain/sprockets on my FZ-1 soon, I hope not to run into the same issue as yours. Mine is bone stock, so it shouldn't be an issue unless they applied that thread lock from the factory.

Not reversed/LH threads. The service manual specifies 94 ft-lbs torque and a coating of anti-seize grease oil (molybdenum disulfide grease mixed with motor oil 1:10). Never mentions anything about welding the dang thing.

Brian, your electric impact gun is great. I'll get it off eventually, either with the gun or with a 2-ft piece of 1-inch conduit over my 18" breakover bar.

If you want to bring it over I have a impact wrench that will remove it.

You can always drill the corner of the nut and safety wire it to the sprocket as well. When my toothed washer bites the dust, that is going to be my plan for the track bike at least. I might try it on the Tuono since I have a new front sprocket I need to put on there.

Yeah the electric impact gun isn't budging this thing so I'm in that mode of desperately trying to stop the rear wheel from turning while I twist on the nut with a 4-ft cheater pipe.

I have a feeling this nut may need to be destroyed in order to remove it.

Have someone sit on the bike and jump down at the same your hitting the bolt with the impact or pipe.
