I put this post also on Canadian forum K100.

I,m looking for some answers so please if someone know the answer....just in case I paste last my post and pics.

So, finnaly we got time to disassamble engine to looking for weird noise. I stuck on outputshaft because can not remove it from housing, that is very starnge but that "half" is keeping the bearing and make me impossible to take out whole shaft...did I miss something???? Please help, see pic.
Also I see a little starnge makks on bearing bed in engine housing, like bearing was sliping inside aluminium housing, or maybe that is just how it looks like. See pic.

And the last case is the starter clutch, three bolts which keeps clutch together were were very untight, like I use 15-20 Nm to unscrew them. Should be like that or they started to unscrewed themselves??

The shaft bearing might be stuck to the bearing seat by an application of Dreibond, and resistance to removal might also be created by the close clearance of the circlip within its groove in the case. If this were my problem, I'd secure the case to the bench, then with one hand on top of the gear wheel to prevent the shaft assembly from being knocked out of the case and damaged, I'd smack upwards on the shaft at the arrow in the photo with a rubber mallet or rubber deadblow hammer. That should overcome the resistance holding the bearing to the seat and allow the shaft to be lifted.

Thanks Laitch. I just want to be sure that did not miss anything to be unscrewed or elso. If that is a matter of a bond will do as you suggested with rubber hammer. I was gettin mad hiting few times at the shaft but without excessive force as I was not sure.

You make it seem exciting! Did you curse, too? Were the neighbors awakened or the police called? Where were you hitting the shaft and what were you using to hit it? Excessive force shouldn't be needed because that would be excessive.

Being 6500km away from what you're doing, I'm not sure either. :giggles

Wellllll....believe me or not but the situation is like I described, I keep case tight to the bench and hit shaft with rubber hammer. And nothing happens...I know it may sounds a bit funny but it is not. If that is the bond it must be very strong. Anyway will do that as you suggested.

Is this a situation to apply heat with a propane torch to the engine case, or would that damage the aluminum structure, and change the milled tolerances for the bearing? Just curious since there's a mallet already involved.

When I look back at the times I've been out of my head with anger and then found a simple solution, I think it's funny—especially when it involves a motorcycle malfunction instead of a life-threatening physical or social malfunction. Living a life of low-grade drama sucks; however, it is preferable to a life of high-grade drama which can be expensive and affect digestion.

I believe the situation is exactly as you have described it but you have not yet indicated the direction of your mallet blows on the shaft during your angry bout with fate. Upward or inward? This isn't your first rodeo, Piotr. You know that freeing seized components takes patience and persistence.

To affirm Natalena's suggestion, try gently heating the bearing at its seat then tipping the case upward and trickling anti-seize penetrant so it will seep into the space between the bearing and its seat. Also, try trickling some penetrant into the circlip groove too. Wait a few hours then try rapping it again. I think the tight fit of the circlip might be stalling removal, if all other fasteners have been removed.

agree with the heat and penetrating oil,  another bit of advice would be place a block of wood under the shaft so it supports the case, then beat on the case with your rubber mallet.  The added weight of the case might help break it loose

a life-threatening social malfunction

Care to elaborate on this?

a life-threatening physical or social malfunction.

Gladly.

An example of a life-threatening social malfunction would be what you are watching as a throng of angry people who have been lighting up buildings, pulling random folks from their vehicles, beating them senseless then torching their vehicles on a May 1980 Miami night because a jury found some policemen not guilty of homicide during an arrest in their neighborhood now surround your truck to stare at you through its windows because you unknowingly drove into this mayhem while you were trying to return home from a night of two-stepping to the twang of a pedal steel guitar, and forces you to consider taking one of the following options: 
    a)    These are folks open to reason and are probably fans of country-western music, so you'll just get out and talk to them.
    b)    The truck has enough ground clearance, power and traction to knock aside or drive over everyone between you and the open road, so you'll do that.

An example of a life-threatening physical malfunction is acute myeloid leukemia.

Confrontation by a stubborn output shaft is small potatoes by comparison.

Uh, wow.  Just wow.

I prefer my potatoes small.
