This post scares me

 

:hammer::stpd:

 

im confused in a way. how did you overtighten then nut....then had the threads comes off when you removed the nut? did you remove the nut more than once this weekend? how many threads are holding that nut on now? and sadly I have to actually agree with butcher on this one....this post scares me..
I dont see how you could tighten it so much by hand you strip the threads but its possible you cross threaded

 

yikes

 

:scared

use the service manual torque specs!

but if your threads have disintegrated..I don't know what you'll have to torque it onto anymore..sounds like you may need a new countershaft

 

When I pulled off the nut for the first time is when the threds came apart. It was in 2 areas on threds one on top and one on bottom. About halfway down the counter shaft. It's on there and won't come off I'm just worried if it's too tight what kind of damage it could cause.

It's not cross threaded because it spun on 2 turns before I used the impact gun.

And the nut was only removed once and put on once

 

torque specs bud!

 

Yeah it's deffinatly over tightend.. Tq says 63 and my wrench is cliking out at 100...

 

Hope you never need a new one. Sticky this post so people know what happens when they decide to work on their bike without a single thread of common sense or mechanical ability.

 

What's the worst case senerio

 

You're replacing the counter shaft. Which means your tearing your engine apart to get to the tranny.

Hope you've got a warranty and a good book of excuses, cuz that bike looks pretty new in your avatar

 

OP where are you from???

 

Seattle.

And no warranty it's a 09

 

:shake

 

Goes without saying. How's it hangin Rex?

 

Hey guys don't make fun Im not a mechanic

 

We're well aware of that fact. Why would a person with no mechanical ability attempt this? You said it yourself, you're no mechanic, but here we are.

 

:corn

its great that you popped on here to find some help for the situation. But unfortunately it's prolly a little late. If it's on there now, just leave it I suppose. But when you need to take it off in the future, plan on possibly not having the bike up and running right away

 

Yeah unfortunately. I'm going to a family friend thats mmi certified for yamaha and he's going to look at it.




And I figured it would be a black and white process of undoing the nut and rePlacing the sprocket, putting the nut back on and bam I'm out riding. How was I supposes to know the threds would fall apart by undoing the nut. No need to kick a man when he's already down

 

Is not considerable to take a die to it and cut new thread?? IMO that would be the first approach. If you have split the engine and have someone replace the countershaft its not a good thing..

 

I don't know if a die would do it. There is a chunck missing on the top and bottom. I'll post pictures tomorrow afternoon

 

Cole... threads dont fall out bro:shake
That impact gun ripped the threads off that thing. Its just a big error. Have your buddy look at it he might give you the straight scoop. None of us were born mechanically gifted. Spend the dough and get a factory manual (can dwnld them for free on the internet and even here is you search). Know what your dealing with and then go about your biz. Good luck dood

 

threads dont fall out? im downloading one right now thanks. hopefully the guy knows his stuff, probably should have gone to him in the first place... lesson learned the hard way i guess.

 

A little of this and you will be as good as new.

J/K:vanish

 

Threads get stripped off bro:fact

 

Yes, but if it's just the threads on the nut that are stripped you'll be ok. If the shaft threads are also rolled, you could try and take a thread file to it and clean them up enough for the nut to thread on properly. That is unless there are enough threads gone that it won't hold anymore.

Why the hell would you use an impact gun on that in the first place, I try never to use them if it's not absolutely necessary, and on a bike I haven't found a use for one yet. The torque specs are there for a reason.

 

the nut is fine its the shaft. haha. but i couldnt even get it to budge even with a breaker bar.

 

*cringe* You should probably put down the tools while you're ahead.

You might be able to drill and tap it but I would always be worried about it. Always tighten bolts with hand tools. Impacts are very aggressive. I used to work at a tire shop. I can't tell you how many wheel studs I've sheered off.

 

Ouch...at this point if you remove the nut again it's only gonna get worse. If there is enough of the thread left though you might still get away with filing it down and cleaning them up. But I would suggest having someone who knows what they're looking at make that determination.

This is why it's important to always make sure the threads are clean and free of debris before you try and remove or start the nut. Hope it works out for you...post some pics of the threads if you get a chance.

 

threads were clean when i went to take it off, just like the guy above said the impact gun just sheered it off, i didnt know it would have such an adverse effect. live and learn

i would like to just leave it on like you said because if i take off again im sure its just going to be worse. with that said my main question never really got answered, how bad is it to have that nut over tightened? will it damage anything on the inside ? i have no clue how the counter shaft system works

 

Don't get too emo over guys raggin on you for a f*ck up, it's all a learning process. Unfortunately, you learned the super hard way not to use certain tools for certain jobs.:fact

From your further description of the problem, my guess is one of two things: (A) whoever put the nut on before you X-threaded it and you putting the gun on it ripped the whole sucker apart, or (B) the nut was seized on the threading of the countershaft (bad/wrong loctite application?) and the gun *notice a trend here?* ripped the sucker apart.

Trying to tap&die/refile/any sort of modification to the countershaft IMO is a huge risk. I'd say bite the bullet and replace it, much safer. Good luck, and just take this as a big, expensive learning experience!

 

(B) the nut was seized on the threading of the countershaft (bad/wrong loctite application?) and the gun *notice a trend here?* ripped the sucker apart.

i think you hit it right on the nose, while taking different parts of the bike apart almost everything had tons of blue lock tight, it did not seem to be like factory.

That sucks...I'm really interested in seeing the pics now though. Usually blue(medium strength) loctite won't damage anything even if there is a ton of it on there.

Definitely a shame to have to shelve the bike for some damaged threads. Hope it's not as bad as described and can be fixed easily.

 

Geez. Rough crowd. There's no reason or benefit to be had from breaking the guy down because he made an honest mistake. I'm sure he already feels like crap and was simply looking for some constructive advice here.

Cole, your best bet is to get the bike to a dealer or reputable mechanic to give it a once over and make sure that you're not risking putting yourself in danger by the current condition of the bike.

That said, it's not the end of the World if you have to pony up to have it all repaired. Costly maybe, but nothing that isn't correctable.

Consider this quote from Tony Scott (legendary engine tuner who's engines have won 28 TT's and every major British championship)

"Whatever a mistake costs financially, the experience it gives you is invaluable"

Ahh you beat me to it snoman...well said.
