Just opened my RS engined box, I'm in there primarily to replace the rear mains but thought, I've got the 2 all steel layshaft/clutchshaft bearings might as well replace the Nylon caged jobbies while I'm in this far
So the endcase was the tightest yet, had to resort to a screwdriver to prize it off, fortunately no damage to the machined faces (I was VERY nervous). This was after 2 hours with a deadblow and nothing was moving.
Just took out the shafts and when the mainshaft lifted the thrust bearing was left behind in the box. Thinks............. ..don't remember that being there in the other 2 I've had apart, so goes to my gerabox strip article and then the parts book, sure enough the bearing is there but there should be a shim (thick washer) and a runner (thin bearing) below it, they were nowhere to be seen.
Now I'm really struggling WTF is going on here, washers nowhere in the box and I'm starting to search local to the box in case I've dropped them.
Evetually look at the shaft and see what I think is the second runner so start to peel it off. The "other" runner turns out to be the shim with the 2 runners behind it. The bearing was just thrown on after all of them and must have been running on the shim on one side and the gearbox case itself on the other using them as runners, scary stuff.
Certain this has left the factory this way, a Friday afternoon assmebly after Gearbox Luigi had just had a particualrly good lunch I reckon
Pay attenion when taking them apart and puting them back together just because you put it back exactly the same way it came apart DOES NOT mean it's right

Indeed... sounds like it was either right before or right after grappa time for Luigi...
This is exactly why I bought the mechanics shop manual for my Guzzi shortly after I got her. It literally lists each and every nut, bolt, screw, and component part in the whole machine, and how to take it apart and put it back together.

What? "Mechanics shop manual"? There's something out there other than the Guzzi Service Manuals?
