@Stig you are right, there are some lubed parts in there. But, they are protected by o - rings within the clutch. Boss/ sleeve/ rollers / ramp is in most of the cases not lubricated at all.
Rubber belt is happy to feel a shower.
THING IS, not to let it sit in its soup, dry it out immedeately by driving off.
In the industry, when I did not have any other option (huge size not available) I took water lubricated ball bearings, and they last.
