Baaaaad bad news....

[Davey-boi]

:( :mad:

Well, my vino is out of comission.... again. On my way back home tonight, my scoot started makin funny noises. Kept driving anyway, cuz she always hums a lil different from time to time. After a lil ways, it dropped in acceleration and then wouldn't budge at all!

So, as soon as I got home I opend her up only to find a destroyed transmission! It looks as if someone took a chainsaw to it. Belt snapped, finned variator pully all scratched up and without fins, V bushings cracked and scatered about, broken pieces of metal (fins from the pully), some random roller wieghts, and anything else thats unrecognizable. My kick start won't work anymore, the teeth got filed down. To top it all off, and I think this is the worst, is the crank shaft treads had been stripped!

Anywho, this all resulted because the nut that holds the transmission together came loose. My question is, how? I tightend it all I could, and she's been running great for a few days now! I just don't get it, it's never happend before. My only guess is that might have put the nut on backward by accident.

Well, so much for riding the vino for the next couple of weeks. Gotta look on the bright side though, this is all repairable and easily fixed (except for the crankshaft, I really hope it's not badly stripped). Anyway, this is a good lesson to everybody... only do mods if you know what the F**K your doin :D !!!

did you use an impact gun?? Thread lock??

[King Vino]

Good thing you got two scooters!

[marylandmark]

OUCH!


Exact reason I am not touching mine...

[King Vino]

Don't feel bad, I left mine stock! I ahte staging glad I only had to do a few at YMC.

the exact thing happened to my zuma today, luckily i was able to push it most of the way home, 2 miles, suddenly didnt feel so smart, all bundled up for the ride. Somone stopped me to ask if i was stealing somones bike. LOL The sad part is, yes, i had flat spots on my rollers and wanted to replace them... I got it home and found the nut that holds the front pully/variator thingy had come loose and stripped the crankshaft. Its not super expensive to replace, just somthing im not thinking of doing myself. Its my only vehicle as of now, so my only option was to just try and re-thread the crank with the remaining threds on the end by just forcing the bolt on. Its a sad pathetic fix and now makes a knocking noise when i first start it up. (goes away once power gets transfered to the rear wheel?) I only wonder how long that bolt will hold or if ive messed up somthing up inside the gearbox?

My feeling exactly!!!!! That is why my 07 Classic is stock and is going to stay stock unless I have the $$$$ to take it to my Dealer for modification. I don't have the tools or the space and I am way too old to screw with it. If I want to go faster than 38 mph, I will buy a faster scooter.

so how did this happen? not securing the bolt all the way after removing the washer from your transmission?

Couldn't you hear the shearing metal?

see if you can chase the threads back with a die.
as said use thread lock.
fyi: i buy a bottle of it about every other week and use it on
every scoot i service.
put the nut on by hand then do the final tighten up with the impact.
set it to a lower setting than the max your wrench& compressor
are capeable of , then you have the high setting to remove it.
there is no reason that you can't remove & replace the nut many times
without the "dreaded loose nut effect"

That stinks. Sorry to hear about that mess. I use a torque wrench to set the nut. I think I recall it set at 28 ftlbs..gotta look it up. I got mine at Harbor Freight on sale for $20. Also good for the rear pulley nut.

Um, you folks realize that the original post was 5 years ago, don't you? Little weird to be offering advice, your 2 cents and condolences after all this time., don't you think? I'm pretty sure this has been fixed.

My father died in 1993...I'm still accepting memoriam cards with cash if you'd like!

[Vino A Go Go]

He He ! That was a good one...only looked back a few dates and didn't pay attention to the original post date. Oh well, maybe some noob will gain some info from it...mainly don't resond to stale posts! ..weird....weird..

i'm glad this thread got resurrected. when I did my variator mod I was sure to use threadlock, all the while thinking of this thread.

I might have used it otherwise, but if it wasn't terribly handy I might just as well have forgotten about it.

I've found that it's also handy (once you get your transmission repaired and back together and that nut tightened with a torque wrench.) to scribe several marks on the head of the nut and cooresponding marks on the face of the variator, (or washer if applicable.) This way, next time you take it apart, tighten it the way Harry has suggested above, until the marks line up, and the danger of overtorqueing it is diminished considerably.... Gabe ::usa::

i will remember this with the mods im gonna do to my tranny
