im am soooo sad. my beautiful onza trials is in disrepair. when i stepped on her today i noticed a horrible creaking. i realized that the left crank arm was a little loose (it doesnt noticably move, just creaks). when i went to tighten it i found the bolt on the side will not tighten. it also will not loosen. the crank arm has been ripped up from crankgrabbing and it appears that the little knob that sticks out is squished a little, so that the dust cap/crank remover is not touching the bolt on one side but is really tight on the other. so it has become an oval (very close to a true circle). There is gunk on the inside. the bolt will not turn no matter how hard i turn it. i dont think the problem is lock-tite since the other side turns without a problem. there is no way i can get the dustcap/crank remover out with the tools i have. it creaks horribly.
hmmm. i think the bolt is a little loose. the problem is that since the entire crank arm is smushed a bit, the bolt wont turn. actually the bolt is tight, but the crank arm is loose. so it wont get looser, but itll do some damage to the splines if i cant fix it. the crank arm will creak whenever i put weight on it, but as i said above, im pretty sure its just because its a tiny bit loose.
i was just kind of wondering if this has happened to anyone, where the crank arm where it attaches to the hub has been damaged from crank grabs. i dont land grabs with my crank (just the pedal) so it must be hitting perpendicular to the side of the obstacle as i jump at it. ill try to post pics later.
