I got my variator off by taking a belt (one you wear around your waist) and looping it around the variator pully and then I wrapped the loose end three times around a 2 foot piece of 1/2 in. galvanized pipe. Then after you get everything tight. you put a breaker bar and whack it w/a ruubber mallet as hard as you can while putting opposite pressure on the pipe. It took me two tries and the bolt was loose. ;D It's a poor man's impact wrench. Plumbers use strap wrenches all the time and there is also a strap wrench designed to remove oil filters from car engines.

Great idea. "Necessity is the mother of invention", as the saying goes.

you can save all that drama and just go to sears and buy a strap wrench....no wacking on the variator man...that can cause major probs down the line.

I hit the breaker bar not the variator.  Why would I want to buy something if I can improvise one. I like a little "drama" ;D |

i use a plastic piston stop that i got from a friend.
it screws in to the spark plug hole and you can get the var off that way. No pounding the crap out of anything and they can be had for about 1.00 some places or go to a hardwear store find a longish bolt and make one.

I like a little "drama" ;D Well it doesnt matter what you are hitting..you are sending shock to the variator,crank,bearings,and everything else attached to the variator....Why buy one?Because they only cost like $10,a small fee to pay not to have to twist a belt and hit bars...you just lock it on and undo the bolt. |

Rookie,
I have done alot of things like what your talking about in a pinch. But I have to agree with ncsk8er pounding on the end of the crank is not the best ideal to do all the time. The force from the piston is between to bearings and not at the end of a shaft take a good look. And read the post on everyones thoughts on not keeping rollers balanced. Whats more I like this form and read it about every night. Posting your thoughts and ideals on how to work on scooters is what this form is for, please keep your name calling to youself no one wants to read it.

Grapevine Texas, it is way up there in North Texas. The city is just north and west of DFW Airport (Dallas-Fort Worth international airport). It is sort of between Dallas and Fort Worth, but on the northen most part though.

I found that the EASIEST way to get the variator off, is to have the factory leave the nut loose! Mine came off all by itself |

Cool.
Definitely a good deal. I got the 1/2" 18v impact wrench a while back when it was on sale.

Go with the 1/2" drive 110 volt impact if you don't have a compressor, and the 1/2" drive air impact if you do have one. The DC powered units are disappointing at best. Stan |

Bummer, thanks for the info. But I'll still give it a shot later as I have the 1/2" 18v impact wrench. So now I don't know if it will work or not. But then i made my own tool to lock the variator with, so I can use a long 1/2" breaker bar on it too. So I hope I can get it off one way or the other.
:-o

I won't say the battery models won't work, but often the first time off is the toughest. The air and 110 volt models just have lots more power. For small people, the Chinese often use a BIG impact to install them..... ;D After the initial removal, you should be fine especially if you lock the fan when you remove the nut.

Before it really happened and the CVT drive belt broke. I wanted to ensure that I could get the variator nut off and be able to replace the drive belt while out on the road someplace. So here are some pics of what I did to be able to fix it in the field. The at home test is a success, so i feel confidant that I can perform this procedure when out on the road, should the belt break on me. The homemade variator tool and 14" break bar wrench both fit OK in my under the seat storage tub. CVT Drive Unit exposed:  The OEM Drive belt is a Bando 835 20 30 size belt. it looks none the worse for wear at about 800 miles on it so far.  My homemade Variator Locking Tool:  Removing the 17mm variator nut using a 14" long 1/2" drive breaker bar wrench and the homemade variator locking tool. I had to use this long wrench, as they used a air-impact-wrench at the factory, and that nut was really on there tight. I had to use two hands and push down hard with my body to pop that nut loose. I then used some blue Locktite to reinstall the nut and tighten it back up. So being able to replace the belt out on the road is not a big problem for me now.  While I was at it, I thought it might be nice to see what the aircleaner looked like too. here is the top cover.  And here is what the air filter looks like with the cover off. Note the grid like strip just in front of the air filter. it contains a foam strip, than you need to check and clean from time to time. You can wash and dry that foam strip and reuse a lot. The air filter is a typical paper filter element that would need to be replaced as needed.  |

Great pics Earl. Cool removal tool. I have some band aluminum in the shed, guess I will make one of these and keep it under the seat along with my spare belt. Thanks for the great idea.

 Great job on the tool, Earl----I love the " design it yourself" abilities of the scoot-dawgers. My CFMOTO service manual lists a "special tool" that you can buy from them and it looks real close to the one you came up with! I bet it costs a pretty penny,too. I have to pull my cover off to find what belt number I have (to get a spare) so I think I will make a tool while I am in there. Thanx for the tip. Art
