Alternately,
- you can just drill a couple screws into your workbench to line up with these holes here or use 2 x 3/8in upside down drill bits mounted in vertically in a vice, set those holes onto it, thus immobilizing the assembly.
- Then use some heat to loosen up the nut on the back plate and break it free with a long wrench (or use a spare set of handlebars for a lever).
- Once you break the nut free, use some big channel lock pliers to break free the back plate.
- also, I noticed that these screws here:
Had been locked in place with little dabs of weld. I had to clear out the slots with a flathead screwdriver and some firm but gentle hammer taps.
- I like this way better because there is much less chance of warping the variator with the vise.
