Driven axle broke on my 2012 M800. Looks to me like the axle was damaged already, the fresh broken part seems to be only in the center. Is this common?
Also, any tips of how to remove the locking nut and the adaptersleeve inside the bearing?

2012-2014 had crappy jackshafts, there was an update available to the one in your second post. Needs a new chaincase bearing to work. Same bearing that is on the clutch side without seals actually. Use a heat gun to warm up chaincase to pull bearing out. Just leave locksleeve on bearing and remove with it. Won't need it anymore.

Thanks for the info!
So the M6000 axle fits on my M800, just need to get a new bearing? Splines on the chaincase side are the same?
Regarding the bearing, would a normal bearing work as long as it has the right size? Might get hold of a SKF bearing and wonder if I just could take off the seals and use it.

Yes the 2015 M6000 shaft will fit with the right chain case bearing. It is the same shaft cat provides in the update kit.

No, you can't use any old bearing. It has to be an angular mis-alignment type.

Got the new axle and bearing installed and all seems to fit nicely. Only a bit worried about clutch alignment now, any good tips how to check this without the AC tool? googled a bit already, but couldn't find the specs for the M800.

If alignment was good before nothing should have changed with new jackshaft as clutch is shimmed to the bearing not the shaft.

I can confirm that. Was driving it all afternoon yesterday and checked the belt at almost every break we had, all looked good.
Thanks for the help, snow is too good to be missing out!
