I installed the new clutch material on the tomos clutch yesterday. First off i removed the old clutch material from the arms and roughened up the area where the new material goes.

I bought some epoxy (Devcon 5-minute) to adhere the material to the arms and a hose clamp to keep pressure on it while the epoxy dried.

So i mixed the epoxy and spread a generous amount on the arms and attached the new clutch material. I hose clamped it in place and waited for an hour.

Once it dried i cut the pads to the correct length. They were still too thick and would barely fit in the clutch bell so i had to shave them down with the dremel and a grinding bit. Even with this i was still experiencing the clutch grabbing slightly at idle so i cut the clutch spring down a few coils. This helped, but didn’t cure the problem. I decided against taking even more coils off because of the weakened state of the spring because of this mod, and the extra pressure on the spring also because of this mod.

I took the bike out for a good hour ride last night and the new clutch performed beautifully. Smooth transition into first gear (maybe engaging a bit too early, but thats ok), and smooth transition into second (I’ll need to do this mod eventually to the second gear clutch). I’m going to open it up tonight and see if the material held up to the stress.
