Can anyone tell me where I can get a tool to hold my variator in place? I have a tool to hold my clutch, but I have not come up with a satisfactory tool to hold my variator securely while I torque it with my wrench.

Here is a link to the one I used for my belt and variator service. It works for both clutch and variator.http://www.ebay.com/itm/Motor-Variator-Remover-Puller-Tool-For-Gy6-50cc-125cc-150cc-Moped-Scooter/162555878162?_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D1%26asc%3D20150313114020%26meid%3D5b81beb370cd4af789bd50e3c7f64b38%26pid%3D100338%26rk%3D13%26rkt%3D30%26sd%3D281533672163&_trksid=p2141725.c100338.m3726 (http://www.ebay.com/itm/Motor-Variator-Remover-Puller-Tool-For-Gy6-50cc-125cc-150cc-Moped-Scooter/162555878162?_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D1%26asc%3D20150313114020%26meid%3D5b81beb370cd4af789bd50e3c7f64b38%26pid%3D100338%26rk%3D13%26rkt%3D30%26sd%3D281533672163&_trksid=p2141725.c100338.m3726)

Thanks Blue. That one works on the Kymco, but the Helix has no holes in the variator face. :-[

I seem to recall reading that strap wrenches work.

Sorry about that.

I bought one with a heavily reinforced rubber strap (2000 lbs of torque) Not enough surface area on the edge of the variator for the strap to grab. It works great on the clutch though.

Impact, air or electric.

I second what CROSSBOLT suggested. An impact wrench.
Personally, I have not had much luck with strap wrenches. They tend to slip.

and you can get the torque limiting extentions down to 70 foot Lb.s for putting nuts back on,.

I made a holder out of a rectangle scrap of 3/4 inch plywood (you can use whatever you've got and if it's thin use two layers). Toward one end, about 4 inches from the end, you cut a hole big enough to allow a socket through to get to the big nut holding the variator. Then you drill 4 holes through in a square pattern about 3 or 4 inches on each side, centered on the big hole you drilled for the socket, and put through large bolts with a washer under the head and a large washer and nut on the other side (facing the variator) with enough bolt sticking out so that they reach between the vanes on the variator. The plywood should be shaped so it covers the variator and reaches far enough in one direction to jam against the frame of the scooter or the floor when you rotate the variator with the hole over the variator nut and the 4 bolts stuck between the vanes of the variator. Then put your socket through the plywood onto the nut and unscrew it.
If the scooter wants to rise up off the floor while you are unscrewing the nut, either sit on it yourself or get your overweight brother-in-law to sit there while you push on the breaker bar.
If this isn't clear, reply and I'll take a photo of the one I made.

De dee, do the torque limiting extensions work with an impact wrench without having to hold the variator? I am unfamiliar with the extensions. Sure sounds like a good solution to me.

Not sure how accurate they would be not holding it. A lot of stuff I can hold by hand, yes it may slip a little but that's ok.

Thx MJR. I could hold it one-handed.

Mr Paul..do you have a picture of your variator?
-
Amazon has many different types. Check for the type that you need.

the torque limiting extentions are made for the impack guns,. and you can tie the brake handle to hold the wheel from turning, which stops the variator turning

Thanks everyone for the helpful replies! I am strongly leaning towards the torque extensions. I have an electric impact gun and I like the simple solution. :)

I use a cheap electric impact wrench, and just hold the variator with one hand while I impact it with the other. If you're nervous about torq settings, use a simple torque limiting extension. I just eyeball it and it works OK. Works on both variator and the clutch. Also the rear wheel nut (24mm), and the flywheel nut.

Thanks JJJoseph. I have a cheapo Harbor Freight electric impact wrench. Love that thing! Just for insurance Im going to get the limiting extensions. Have a good one...Paul
