I don't think a sanding disc is a good idea, I used very coarse Emery cloth and roughed the glaze off the friction plates by hand. Trouble with leaving it for now is the more they slip the more they glaze, so it can get worse quite quickly.

 

I appreciate that warning. Do you remember what grit emery you used? 40? 60? 80? I understand what you are describing, and I will do just that.

Getting worse is why I'm going to leave it alone. It's been the same for 2 years now. If I put in the new clutch in tomorrow, I won't have time to test it. If it still slips, it will quickly ruin the new clutch pack. But if I leave it and it gets worse during the trip, so be it. One of the crazy teenagers will be driving it, and it might help him slow it down a bit. It still does close to 50 on flat ground, which is more than fast enough. I've warned him not to burn it out, or he might be sitting out for half the trip, so it's up to him.

Here are the monsters "taking it easy" on the blue Lakota and the Bayou. At least they started off easy, until getting out of my view. Then I heard the engines rev up a lot higher, and this is what I saw when they came back:


Once we get back, I'll go into it. I plan to deglaze the existing plates, then add an extra plate and see how it runs. If the existing stuff is too far gone, I'll use the new clutch pack.
