I made this video showing how you can remove the variator nut on a Kymco Super 8.
How to remove the variator nut on a Kymco Super 8 (http://www.youtube.com/watch?v=zYCasW5pY24#)
-
Ha! pretty slick if ya got the diamond pattern ;)
-
..same as the A50!!!
;D
-
Made it look simple.
My P250 requires about 90 ft/pounds to break the Variator nut loose.
Great little video.
-
The Kymco Super 8 servicemanual says to use between 5,5 - 6,5 kg-m torque.
That should be the same as 40 - 47 pound-feet.
I dont have a torque wrench but you have i good feeling when tightning the nut when doing it this way compared to using a impact electric tool.
-
..i have a Torque-O-Matic elbow...
..no, really!!..
;D
-
what size is that wrench?!
-
That would be a "one size fits all" wrench.;)
-
Yeah, except the different sizes are different lengths.
-
The little wrench is a 9 mm. That fits on my scooter but i think other tool brands might not be the exact same length.
-
"one size fits all"
..yeah, that's what she told me..dammit...
-
just did this to put in rollers it realy works cool thanks nice to have online friends.
-
Anyone have any thoughts on using a piston stop for loosening/tightening the variator nut?

I think it should be just fine to use a pistion stopper.
-
I just looked at what a piston stopper is. As best as i can tell, it is a device that threads into to the spark plug socket using the plug's threads and the other end presses against the piston head to stock the piston from moving.
I am not willing to risk the threads of my spark plug nor am I willing to punch a hole into the end of the piston. I KNOW i am fully capable of generating enough force to punch an eraser sized hole in my piston no matter how thick I think it is.
I have twisted the driven square part off of three...count them...three ratchet wrench handles and two adapters in the part month using nothing but my hands on tools, no motors.
-
You wont damage the thread if it is screwed in properly, but my concern was about cracking the piston. I do have one but have not used it, I find it easier to use the clutch holder. But surely your variator nut wouldnt be that tight, would it?
-
Unusual that a ratchet should be stronger than the square drive.
-
Clutch holder?
-
A device to hold the clutch housing while you remove and replace the nut, in the case of the GPX250, 90 f/lb. Works fine on the variator drive face.
-
..like this..to hold the clutch bell...
-
..to hold the drive fave..
-
..to compress the clutch...
-
Cluth holder.
