Title: Cush drive rubber options/mods
Post by: amamet on April 08, 2020, 06:34:20 PM

I’m about to button up the rear wheel of the lemans and can’t decide if I should put all the rubber wedges back, half of them, drilled/not drilled  etc... ugh

   A new and unproven technique is to freeze them like a hockey puck. Get back to us with the results. :evil:

I was in the same place when I mounted my tires last month. Ive only had the bike a year, and had not been in to it yet, and didnt look like any one else did either. I was wondering what to do, but since the rubber was still a little soft [only 10K miles on my 02 California] I just cleaned it all up good, and used some grease to lube it all up. At least now its not dry/rusted, and can work how it was intended to. Ill revisit it next tire change...

I bought all new rubber pieces so they're kinda hard.  not even sure what the difference in feeling is like having all 12 installed vs every other pair with the 3 drilled holes.  can anyone shed some light on this mod?

BTW, don't try a drill bit.  Generally they just bind and tear.  Make a hollow tube with a tapered, sharp opening end.  That will cut out a nice, clean core piece of the rubber.  Nuisance to take the tool out of  your drill and poke something through to extract the core which has been cu out.  Something like this:

But easy enough to make your own out of tubing.  IIRC, I bored a 3/8" hole near the pointy end and  then two, side-by-side 1/4" holes across the wider top end.

I don't know if it actually helps, but I've seen three rear drives with the input splines beat to hell.  Can't hurt.

I've been running for years with half the rubber pads and those are drilled, no problems to report, splines are original and starting to show signs of wear but still very servicable.

A spade bit worked fine for me.   :bike-037:

I’m going to try the every other and drilled method, what the hay. I’ll grease everything up with some of the sig wurth spline grease I have them seal it up. What could possibly go wrong

Remember, it is not every other wedge.  It is every other PAIR of wedges.

Yup 3 pair. Is the spline grease better than the belray waterproof grease for inside? Or it doesn’t matter
