Can't get the 17mm nut loose. Left liquid wrench on it overnight. Used an air then an electric impact wrench while holding the var still with tool. later heated the nut with a torch. Still no luck. Cracked off one of the two holes that you put the var holding tool in. Not sure what to do next. Any tips?

would try heat again,then a spanner wedged in the case and the variator to stop it turning, then a big bar on the nut
-
The nut is so tight I think I would bust the case if I tried that. Going to keep soaking the nut with anti-seize fluid over night and will try more heat again tomorrow. Thanks.

love the dog pick though always makes me laugh. just cant believe what a tit the bloke was you took it from.

Sometimes if you try to tighen stuck nuts etc instead of loosen them it can free it. Worked for me in the past on other stuck things. Then again it could just make it tighter. I would leave it to soak overnight in a good penetrating fluid, Plusgas works well for me, not sure if you can get it over there tho.
If it comes to it you might need to get a dremmel or hacksaw and cut it off and just fit a new one. If you can cut it near to tbe crank as poss and then chisel it to split it then it should come off without damaging the crank threads.

Maybe this'll help -- it's how I do mine. http://www.kymcoforum.com/index.php?topic=3814.0 (http://www.kymcoforum.com/index.php?topic=3814.0)

I used a var tool to try and break the nut loose. It broke off one of the two pin holders (yellow circled in your pic) when I hit it with the air wrench. After sitting for two days covered in liquid wrench it still won't move.
-
Think you may have to resort to cutting it off, unless you know someone with a garage who may have a torque wrench with more torque?
-
The crank threads should be harder than the nut threads btw so if anything strips threads it ahould be the nut not the crank.
-
Well, sheesh, that's on there bad. Maybe someone used locktight on it? I guess, then, I agree with Streido, you might just have to cut it off. Yeah a dremel with one of those thin carbon cut-off wheels cutting as much as possible -- then a cold chisel to crack it the rest of the way.
That can get a little messy since you might have to dress up the crank threads afterward in which case gotta have a die and so on to do so. Not to mention having to order new nut and washer.
By the way, I found a hairline crack in my washer once. Maybe I had been tightening to much previously. Anyway I used it till a new one came in.
Situations like this make me wonder how an experienced shop mechanic would proceed? ?
-
Experienced shop mechanics have Snap On impact wrenches
Of course, that would probably twist that cute little crank shaft right off :D
Running the impact in forward and reverse over and over does work and it's worth a try.
You're likely gonna have to cut it off. Dremel then a cold chisel is a good idea. You don't want to cut all the way through, most of the way. Hammer and chisel the nut in the counter clockwise direction. The nut should either split or loosen up enough to spin off by hand.

I always use locktight on my variator and clutch nut, its a must to stop it working loose and coming off. Never had any probs getting them back off tho.
-
The torque from the rotation of the engine won't let it back off.
Not saying it doesn't need to be tightened, but I don't think loctite is necessary. Of course the blue stuff won't hurt. Just don't use red! You may never get it off :D

Well.............actually i fitted a new variator nut a month or so ago, went for a test ride, got 200yds and heard what i thought was a strimmer/bush-whacker. Scoot felt down on power, then i realised the noise was from my cvt! Pushed it home and looked inside fearing the worse but it was only the nut which had come loose. Was still on, just loose, so the outer variator had a wobble in it. So it does happen, thats prob why the locktight them at the factory.
I used to use the green stuff and even with that it always came off no probs with my torque wrench, now i use Blue just cos thats what i have. I always feel safer using it just in case :o
-
Well... I guess it does happen
Didn't come all the way off though ;)
It's just a good thing it didn't strip the splines on the crank when that happened
-
it must have way to much LOCK tight on it. HEAT THAT BITCH UP.................................
