I have a 2007 150cc Roketa scooter
I can't get my variator off it has a 17mm nut holding it on and I put an impact on it and it won't even move. Is there a secret to getting this off? Also this is my belt size 835 20 30. I also saw some where on the net that the engine is a GY6

If you put an air impact wrench on it, make sure your impact is set on reverse to remove the nut (I know, I just had to make sure). If it still won't come off, then make sure your compressor PSI is at least 90 (if capable). If it still won't come off, it could be a crappy impact gun. The first time I took mine off, i was using a crappy impact gun and had to just kept it on the nut, it eventually came off.

I have a 120 volt AC impact wrench which is capable of 240 foot pounds of torque. Took less than 2 seconds to get my variator off.

I had to press the button rapidly between counter-clockwise and clockwise position, and it
finally broke loose after a few tries. It wouldn't come loose just using the one direction to
loosen it.
Question: Is it ok to use the electric impact wrench to put the nut back on again?

It would be like trying to tighten car wheel nuts while the car was mid air. |

and it's advisable to use Loctite when putting the variator nut back on...just to make double sure it doesn't come loose on you
i had the nut come loose on me once, even after i had used an impact driver to put it back on....don't want to go through that again ;D

That's was just happened to me. I used an electric impact wrench and blue loctite and the
nut still came loose. Maybe because it was a cheap $50 impact wrench from Harbor Freight.
Had to order a new variator. A friend of mine used the red loctite which has more strength
and his stayed on, so I will be using that next time. I had read somewhere that you shouldn't
use the impact wrench to put the nut back on, so that's why I asked here.

Do NOT use the impact wrench to put the nut back on. You cannot control it and it will cause alot of damage.

... I used an electric impact wrench and blue loctite and the nut still came loose. Maybe because it was a cheap $50 impact wrench from Harbor Freight.... i use an electric impact driver from Harbor Freight also....with a digital torque display and rated to 250 ft lbs....with the blue Loctite, nut seems to be on pretty good i believe the torque for the variator nut should be around 40-45 ft lbs |

I think I might know now what I did wrong when I reinstalled the nut. harrywr2 made the
following comment in another thread which makes sense:
I had the belt pretty tight in the variator, which was probably keeping the nut from getting
tight even with the impact wrench.

One more thing is this nut standard threads or reverse threads? Also is a Roketa 150cc GY6?

Normal righty-tighty, etc standard threads.
Yes, on the Roketa 150cc = GY6
Also, when putting the variator fan back on after installing a new belt, tighten the nut a little, rotate the variator (or clutch) so the belt rotates, then tighten a bit more, then rotate the belt again.
Repeat 3-4 times before the final tightening. This will help the belt settle into a natural "groove" without being pinched.

Hi, I don't mean to jump in on the conversation but I'm new and am having trouble. I have a Bashan 150cc that the belt broke while I was riding 50mph. Pieces of the belt go stuck in the variator, and everywhere else, and when I put the new belt on it does not clutch correctly. When I start it and let the back wheel down it stalls.Same if I apply the brake. I read something on the forum about the weights might be stuck or something, or there are pieces in the assembly. I also broke the face drive fan trying to get it off. I'm ordering a new one but wondering if you have any tips for getting it off. Which way to turn to loosen? Thank you.

I also broke the face drive fan trying to get it off. I'm ordering a new one but wondering if you have any tips for getting it off. Which way to turn to loosen? Thank you. To get the nut off, its standard threads, Righty Tighty, Lefty Loosey, Same for the clutch and its a 17 MM also. Once the belt breaks the rollers in the variator will get all out of whack and it will shake like a 90 y/o man. Also little bits of rubber and threads get in EVERYTHING. Best thing to do is go buy 3 cans of CRC Brakleen and spray everything clean clean. Take the clutch bellhousing off and spray in the clutch real good too. this stuff evaporates real fast and if you have an air compressor and a air blower, you can dry it instantly. Use some sandpaper on the clutch shoes and I found that some gasoline and a rag will take the rubber out of the inside of the clutch bellhousing really well since the heat has basically melted it in there. Once the clutch shoes are clean and the inside of the bellhousing is clean the clutch will be nice and smooth when you take off. Dont forget to wash the inside of the CVT cover too. Once you have everything super clean, hold the variator tight together so the rollers don't fall out of whack again when you slide it on. . Also its a good idea to have the scoot leaning to the right a little on the center stand or at least totally level so it will not slide apart on ya. When you go to reinstall the clutch, put the belt on it and squeeze, turn it some and squeeze...do this a few times so that the belt goes down in there then put the belt on the variator then put the fan on. If you don't do this, as said above, when you go to tighten the variator nut it will pinch on the belt and will not tighten up correctly. Do all this and it should be smoooooth running.  |

I presume you broke the fan plate because you did not have an impact of some sort? A good impact is almost a necessity to get the variator nut off an electric one or if you have an air compressor I like air better but either will do. When re-installing the variator be sure to put a small amount of Blue Loctite on the threads before you put the nut back on. JR |

Sure isn't as easy as an impact wrench and they can be used for lots of things too! www2.northerntool.com/power-tools/impact-wrenches/item-15877.htmOh yea people like Earl and some of us others who do know how to make stuff can make this tool but just like the bought one you must have these holes on the variator plate, some do some don't the 250-B like Earls and myself does so keep this in mind but the impact works on all of them!

Well maybe he doesn't have a shop either to make one which requires tools also and one still needs a good break over Bar to use the manual tool so the cost would just about even out. Also that was a medium cost impact did have free shipping which made it cost effective and there would be shipping on the manual tool also so the costs are close to the same. One can also get a cheaper impact if they look and again it will have other uses if they arrise where as a manual variator tool is good for one thing a variator! JR

dave04I have also seen a tool that you can have made at a competent machine shop. its basically a piece of re-bar in a "U" shape, another piece welded onto it for a handle (the longer the better) and the pins for the holes welded to the "U" shaped piece but the pin part has to be done exactly right or the hole will get a chunk broken out of it if there is too much sideways pressure applied. I have seen photos here somewhere but i cannot find them now. When I run across them I will show them to you. I have a 20 gallon 3¾ HP Air Compressor and a Ingersol Rand R231 which zips those nuts right off but I sure cant carry that rig on the road with me. I want to have one made like i described above to carry with me OR just make sure I keep check on my belt. These Chinese rubber bands are junk, the most I have gotten out of one is 1000 miles. I just put a Gates Powerlink on the other night and It better last at least several thousand miles. My kickstand is about an inch too long. I have also considered having it shortened so I can then remove the CVT Cover and center stand and just run without the cover altogether. (the center stand right side foot rests on the header pipe and rattles thats why i would take the center stand off unless I can figure out another way to put a stop on it so its not hitting anything). MODIFIEDThe same tool i linked you to or the fabricated one can be used on the clutch bellhousing as well. I dont know how you are fixed for tools but yeah a breaker bar would be needed also. If you dont have one , a Craftsman one wouldnt be all that much I dont think, however if you wanna go for the good stuff get a MATCO C16FB 16" long ½" drive Breaker Bar. That sucker is solid tempered steel not cast, I dont remember what it cost its been so long but it will last ya the rest of your life. (New today from MATCO its $86.75 plus tax unless you can get lucky and spot the MATCO, Snap-On, MAC or Cornwell truck in your travels but they would probably want even more. I had a Craftsman one break while trying to take the flywheel nut off a VW Engine and a piece hit my cheek just about an inch below my eye so as far as HEAVY tools I went with the good stuff from then on but Craftsman would probably be fine for a scooter variator nut  ). I just like the idea of being able to take belt tools with me on some of the long trips I am planning this summer. You can also get a slightly longer belt, use a 3/8ths ratchet and with the help of the ratchet, slip the belt over the variator and you are on the road again granted that your rollers didnt go all funky on ya. The cheapest tool that you can buy that works good is an oil filter strap. Its like 10$ at NAPA. you could use a breaker bar, brace it against the ground then use a ½ ratchet and give it a good downward kick with your foot and off the nut comes. Viola! More than one way to skin a cat, ya just gotta think of what kind of riding you will be doing and be realistic about your needs.

Cruiser 66 That looks good especially for a home made job, I can see the patterns as you cut this out with a grinder cutting blade combination didn't you? Also drilled the holes until you got it to line up with the variator holes in the plate? Now guys that's homemade Fabrication here at it's best!! And who said you had to go to a machine shop?
But now there's one thing I can't seem to figure and it's the I am going to build me a tool that I can carry with me for roadside repairs when a belt blows apart? Hmmmm Lets see yesterday just for kicks while I was installing my new 12 gram Dr. Pulley sliders in my 250-B just for kicks, I with my old arthritc hands mashed the belt down into the clutch thus spreading the plates apart and then with the added slack took the belt off of the variator without having to unbolt it again just for kicks. So is it really necessary to have this tool, heck now this little tool would be no trouble to carry along but is everyone having belts come apart that bad? Oh I see the problem had to go back and read a little more, "it's the cheap Chinese belts" , heck I thought when ya went through some of the cheap Chinese junk like hoses etc. ya just put a good Gates Powerlink belt on to start with, at least I did. Oh well it's just like the saying ya get what ya pay for!!
Again great homemade tool 66!! JR

Thanks JR. You have a fine eye for homemade tools and fabrication in general. Used a 4 1/2" angle grinder for the roughing in and a dremel with a cutting wheel for the teeth. I like the option of using the tool especially if the belt shreds while on the road. At least you can check the weights to make sure that they are clean and no crap got into them. Besides it didn't cost anything to make since I had the pieces lying around. Can save someone a lot of money over an impact wrench. Also the smaller scoots don't have any holes in the variator for the other style variator tool.

Yep That's what I was saying all variators don't have the holes but with this one a guy can get a grip on it!! LOL Another thing you mentioned made me rememeber something too and as I stated on the belt with the 250-B you don't have to worry as much with your rollers or sliders as this variator has a cover that bolts on so it's not near the worry but on the 50 and 150cc I now remember that's not the case and one might sure need to take this off on a belt explosion as you stated, good point 66 and again that tool along with a break over bar would get ya out of trouble and be easy to throw under the seat. Great great job!! JR

Thanks everyone, I will look for an impact driver. Once I get it off is there anything special to do to make sure it's going to work properly when I put it back on, other than clean the bits of broken belt out?

Once I get it off is there anything special to do to make sure it's going to work properly when I put it back on, other than clean the bits of broken belt out? Yes make sure the rollers are in correctly and make sure to squeeze the clutch together like i said so you will not be tightening against the belt when you put the outside variator plate/fan on. Also, there is a dimple on the kick start shaft, take a screwdriver or something and push IN on the shaft while you are taking the cover off. |

How about this Impact wrench www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=94855$40 140 ft. lbs. maximum torque Variable speed, 0-2400 RPM 1/2'' drive with spring ball and clip Rugged all-metal nosepiece Comes with rechargeable NiCD battery and charger; 1700 BPM Would this be good? The better wrenchs are 240 ft. lbs but i am guessing you don't need that. If its really variable speed then how much rpm should you use to put the bolt back on? |
