We also have a good recording of that session up on the interwebs:

It is streaming from the top for now. I will add play/pause index points as soon a some time opens up, or when riding season ends ; ))

I have tried this link several times but it is not working on my stupid computer. These are great pictures. I appreciate them a lot.

That link was posted just over four years ago.

If you are going to be maintaining your vehicle, go out and buy a socket set, some wrenches, and a bunch of screw drivers. If you only buy the sockets you need for every project, eventually you will have a whole set, but it will cost you a lot more than if you just bought everything together.

If you don't want to spend money on new stuff, you can shop around for used tools. I have a whole bunch of Snap-on tools from the '50s that I got at estate sales. I have bought small boxes full of tools for $10 and vise grips for $1, but it is a bit harder to find metric tools that way.

I guess that I have a tool habit and it is hard to wrap my head around buying the absolute minimum number of tools.

Use a 6mm combination wrench to block the variator as i do.It costs nothing.

I will have some help so an extra hand will be avail, thanks for the idea of the U bolt.
I am thinking the tangs will have to be bent at 90 drgrees to the loop to get a socket in there on the clutch nut, unless the U bolt was 4" long.
The threads on the U bolt wont damage anything?
I am replacing the front fender too so it will be at least half the day doing all this.
Wish I could afford to do some clutch work at the same time, new springs at least, oh well, one thing at a time for now.
Thanks for the tip.

The threads won't do any harm. A picture:

Sorry it's taken me a while to post these. I'll do my best on the captions, but if you want to chime in with changes, I'll update them.


Take off the left side body panel. You may also need to remove any crashguards or racks it they get in the way of removing other parts.



Rear hub cover removed.




The next step is to take off the clutch nut.




Insert the special clutch holding tool over the nut, inserting the pins on the tool into the slots of the cover. You may have to jiggle things a bit to get it all to line up. Do not use a screwdriver to hold the clutch instead of the special tool!!




View showing the clutch nut removed.




Shove the air filter out of the way once the bolts have been removed.




Now you can start to remove the bolts that hold on the cover




As you remove the bolts, pay careful attention to any clips holding brake lines and other lines.




Some bolts may be awkward to get to, especially with crash bars




View with the cover removed





Check the inside of the clutch bell for grooves, irregularities.





Using a special tool to hold the variator cover in place while the nut is removed





Pay attention to the orientation of the washers. It's important when you re-assemble to get it right.




Taking off the outer plate of the variator.




Half the variator removed




Feeling for grooves or irregularities on one side of the variator.




View with the variator, belt and clutch off.




Feeling the roller grooves for any notching or roughness.




Using some green scotchbrite pad to remove any accumulated gunk in the roller grooves.




Feeling the other side of the variator for for roughness or grooves. It should be smooth.




View of the clutch / variator area with everything off




Cleaning the roller grooves with brake cleaner. Pretty much everything should be well cleaned before being put back.





Reassembly is in reverse order, using new belts and rollers. Rollers can develop flat spots, belts will show signs of cracking, delamination and heat damage.
