Stuck Sprocket Nut? A final desperation solution ...
I've had tough times removing sprocket nuts in the past, but they've always budged eventually with an impact gun, sometimes after adding heat. Tonight, though, I rounded off the wimpy nut and had to come up with a new plan.
I found a big nut (1.25"), cut it in half, did some gutting and welded it onto the rounded Kawi nut. Then I was able to get it off easily with an impact gun.
I can't help but wonder why Kawasaki used such a stupidly shaped nut. I assume there was a reason, but I can't guess why it has so little meat to grab.
I am vowing to put it back together with a half height nylon locking nut, assuming I can find one. I think the thread is 20MM x 1.75. Can anyone confirm?
On edit: Threads are 1.5 pitch.
When I locate the better nuts, I'll post here where I found them. I am hoping that will solve the problem once & for all.
