Epic.
You either tell the tallest tales, or you are having a serious adventure.

looking forward to the pictures and eventual ride report.

Guys - any leads on where i can get clutch plates? Apparently the country of Germany has zero in stock! Am not getting much luck with the UK, and am waiting on the US to reply...

Anyone? People are quoting me 2 weeks to order, and then 1+ weeks to deliver.

Failing that, what are my backup options? Is there a way to "re-energize" worn plates? Maybe put some spacers in the basket to push the plates together more?

Check the clutch plates, my research showed the steel plates in the later models were thicker and they used 1 less plate, you may be able to get a kit for the earlier model and reuse the metal plates you have and only the fibre plates from the kit

Beyond that some of the EBS resellers should hold stock of EBC plates, EBC UK were very responsive to some research I was doing a while back and they may be able to point to who has stock

If all else fails ... you can use screws between the plates.... if all else fails . You can also try roughing up the plates if they appear to be "polished". Like someone else mentioned

Thanks for the heads up on the k60s . Pretty sure no tire hooks up in sand dunes though!

the pirelli scorpion mt21 do a great job in really deep soft sand, we have no shortage of powder sand in western Australia and they are the only set ive found that give reasonable mileage and good soft terrain traction.

Nylon,

First of all, happy to hear you are fine! It does look like your adventure will just keep on going for a while. I checked with Max BMW and none of the stores has the plates. Furthermore, none of BMW warehouses in the entire US has them. I just have a thought that maybe you can use the plates from a Dakar, since it is supposedly the same motor. However, the part numbers are different. People that have more experience with it might want to chime in. But, if the Dakar plates are usable, you might have a few more options in your search.

As for squeezing a little more out of the original plates, you might want to use thicker oil, rough up the plates with coarse sand paper, make sure you have play in the clutch lever (no pressure on the lever at all), and use the clutch only to get going,- shift gears without using the clutch. Keep the clutch engaged and as cool as possible. No off road and no uphill. All off this, of course at the risk of getting stuck again.

One more thing, in many countries, where parts are considered much less disposable than in our western world, there might be services to renew the friction lining of the plates. One more direction...

Let me know if I can help.

P. S. And after thinking a little more, I am leaning towards: you might have glazed the plates (as someone mentioned), as opposed to worn them out. In other words, you still have the thickness of the linings, but the linings are so smooth that they provide little friction. This usually happens from overheating. The surface just melts and is smoothed by the metal counter plates.

Again, roughing the surface would get you going, but you would have to work pretty hard at it since the glazed surface is very very hard.

I am hesitant to suggest any kind of washers, screws, or anything else that redesigns the original clutch. These kind of fixes usually get you stuck worse than the original problem.

Good luck!

Don't forget scenery of the female persuasion! You epically failed to deliver last time.

Glad to see you're all good. Dang, that IS an adventure.

Nylon,
If the clutch just slips helplessly under no load, it's probably worse than polished. The only way to improve matters is replace at least the friction plates or increase pressure by adding another plate. If you add a plate, then your hand will wear out.
If it slips as you apply power, roughing up the surfaces may help.

So far I've found this Lucas clutch kit:

I'm still looking for an EBC part number.
Not sure about delivery.
I'll keep looking for you.

.. im betting that he gets a mechanic to hack his stock plates.



FleaBAY: these are for the Dakar. just trying to give some options

I think the EBC part number is: CK5636

I do think the drive plates are glazed, and because the friction plates still have material on them, will see if i can get somewhere with the sandpaper/spacer solution.

Will keep you posted.

Glad to hear there is still meat on the friction plates. I use wet-or-dry or emery-cloth type sand papers when roughing up metal. Scratch the plates radially (outwards from the center) and not circularly. Sanding in small circles while rotating the plates also works well. You don't need really coarse sandpaper: 220 or 320 grit should be fine to break the polish.
Make sure to wash the plates thoroughly afterwards. You should be able to get kerosene everywhere and that will work well.
Keeping fingers crossed that it works. Worth a try anyway.
Try without spacers if possible.

Correct me if I'm wrong, as I have not had these parts in my hands. In a pinch you can also add extra washers to increase spring pressure (extra washers @#19 in diagram)

Correct, adding washers will increase somewhat the pre-load (the Normal force for those engineers out there). It will also increase force needed at the clutch lever to overcome the pre-load.
Adding washers is one way to compensate for overall plate wear but unfortunately friction plates rarely wear out evenly. Usually one or two get very thin while the others are almost new.
