Removing 15 tooth front sprocket?

I have been trying to get the front sprocket off my '08 KLR for over an hour. Had my wife standing on the brake while I tried to use a 24" cheater bar. That just got me a bruised thumb and middle finger knuckle. Tried my air impact driver, that did nothing either. The retaining nut has been soaking in WD40 the entire time. And yes, I did un-bend the safety washer.

Any suggestions?

Edit: I sat there with the impact wrench chugging away for about 10 minutes, and the nut finally broke free! The 16 tooth is now installed! A little clean up, button on the cover, and she'll be ready to go!

God Bless,

Cliff

I always use a bit of anti-seize compound on the splines and threads on re-assembly. Makes the next removal much easier.

Gray-haired riders don’t get that way from pure luck.

Bigger breaker bar..

72ft lbs is what it needs.

Are you using the stock nut or the fancy Eagle Mike Nut?

I did mine recently and went with the Eagle Nut. No more bendy washer...

Glad you got it sorted out.

I put the stock nut back on, because that is what I had available. My thumb is now quite swollen where I hit my side bars. However, I find the 400rpm drop at highway speeds very satisfying! I can't wait to see the effect on gas mileage!

God Bless,

No airtools...

What I do is put the back wheel off a curb or front wheel against a wall with someone sitting on the bike with the brakes on. 1/2" drive breaker bar 2' long will break it loose.

Those sound like good tips with blocking the front or rear wheels.

So far it's been working for me with a friend holding the brakes and sitting/standing on the bike.

I've done mine so many times in the past few weeks that I might actually be able to get if free by myself if I tried.

I've been switching between a 16T, 14T, and back to a 15T. I think I prefer the 15T for all around riding.

Just curious, why no air tools? Replaced my chain an rear but I can't get te darn nut off the front. Will run it like it is if I have too but really would prefer te new front as well. Have tried all the tips anddont remember it being hard hard last time. Frustrated... Thanks all.

I don't have air tools.

Maybe try heating the nut might be some thread locker on it. Use a heat gun or carefully with a propane torch!
