Michael Jackson Posted January 24, 2009 Report Share Posted January 24, 2009 few questions.. why is the front sprocket nut made of aluminum? it stripped once last summer while riding and it popped off and ended my day, so i bought a few from yamaha and put them in the toolbox now im out riding today a bit and notice the front sprocvket has a bit of play when i stopped, but only on the left side i can move it in and out with my fingers, like the threads are stripped again partially, i just replaced it this summer., whaty could cause this? i replace the metal tab each time, bend over 2 corners, make sure the big nut is very snug, i have never used locktite on it though.. i know its about time for a new chain, but could side to side play in a chain put pressure on that nut and force the soft alum to strip on the steal threads? i havnt taken it apart yet , its too fuckin cold to be playin with that shit..but my guess is the nut is stripped again, i got a couple so im not worried, but wtf could be causing this?

locogato11283 Posted January 24, 2009 Report Share Posted January 24, 2009 not sure where you got your info, but the front sprocket nut is absolutely not made of aluminum. if you have one that is made of aluminum, its not the right part.

Michael Jackson Posted January 24, 2009 Author Report Share Posted January 24, 2009 (edited) k yea your right, my bad, just went outsidee and got the extra one still in yamaha bag, definitly steal, but they are always shiny and dont rust, are they stainless? and if so, stainless is soft isnt it? what about the rest of my questions , what could be causing this? i think i am installing them 100% correct... i dont mind buying one a year at $5, but thats not the point, wtf is goin on here?!

NYUK Posted January 24, 2009 Report Share Posted January 24, 2009 slop on the threads of the output shaft. how are you tightening the 32 mm nut? i give it a hit with the impact gun. if your threads are sloppy weld it on. then replace the tranny shaft when you do a tear down.

NYUK Posted January 24, 2009 Report Share Posted January 24, 2009 an adjustable? stop workin like a chinaman. get a breaker bar and a 32 mm socket from sears. a big socket and breaker bar will tighten it good enough. i guarantee you can`t get in the spot to tighten it with an adjustable. doing this will cause slop in the output shaft threads trashing it. get the right tools mj.

locogato11283 Posted January 25, 2009 Report Share Posted January 25, 2009 WTF!!!weld it on????lol..your just joking right??? if the threads on the shaft are trash then he might as well. at least he will quit losing nuts until he can tear the motor apart.. MJ, i simply tighten mine with a 1/2 socket wrench and the right size socket. sometimes i have to pull mine in a hurry at hillclimbs to adjust gear sizes. ive had the same nut since ive had my 10mm motor.. which is about 4 years now. i think you need to swap out the shaft and get the right tools and you wont have the problem anymore.

locogato11283 Posted January 25, 2009 Report Share Posted January 25, 2009 you guys are on crack.. they dont even come much more than hand tight from YAMAHA... really the nut if just there to keep it on the shaft.. and the metal plate behind is to keep it from spinning off, there is no reason to wrench down on this nut other than wasting your time i agree to an extent. i get mine snug, and then use the washer to keep it from coming off. hand tight is a little loose for me, so i snug it just a little bit.

AKheathen Posted January 25, 2009 Report Share Posted January 25, 2009 you can pinch the nut in a vise too, to make it a lock nut. you will have to crank it all the way on, instead of just spinning, but it shouldn't loosen, even if the threads are worn. you'll have to find a big vise though, or smack it with a bfh Quote Link to comment Share on other sites More sharing options...
Michael Jackson Posted January 25, 2009 Author Report Share Posted January 25, 2009 so if this is correct what ur saying about snugging it a bit, why the hell would mine be coming off? when i first put it on, its tight as can be, there is no slop in the threads, 8 months later the threads on the nut are all chewed up, again, but the threads on the shaft are fine, the nut must be softer metal, no ?

locogato11283 Posted January 25, 2009 Report Share Posted January 25, 2009 do you have the retainer clip behind it? if so, even if it gets a little loose it shouldnt be coming off. Quote Link to comment Share on other sites More sharing options...
Michael Jackson Posted January 25, 2009 Author Report Share Posted January 25, 2009 do you have the retainer clip behind it? if so, even if it gets a little loose it shouldnt be coming off. of course, bent over the nut on 2 edges, i replace the clip as well everytime i replaced the nut really theres no way for the nut to back itself off the threads, without it bending through the tabs on the clip which of course cant spin too because its held in place by the splines on the shaft, im clueless here...im not 100% sure yet because i havnt taken it apart, but from the way the nut is moving on the threaded shaft, how only one side has play in it, would tell me the threads are stripped, but if the threads on the shaft had slop in them wouldnt i notice from the get-go? when i put a new one on it is snug as can be and tight as hell, im clueless here.. i know using an adjustable isnt the right tool, but i snugged it pretty dam tight, and like speedy said they come from yamaha hand tight... hell my friend used to ride his banshee with his hand tight with play in it for years and never had a problem Quote Link to comment Share on other sites More sharing options...
