So I finally cleaned up enough of our garage so I could strip the bike down to put in the new gear selector shaft I bought last month. Not bad, only a 2 1/2 hour job to get the gearbox out and pull the cover off.
Looking at the parts diagram (http://www.realoem.com/bmw/showparts.do?model=0504&mospid=51753&btnr=23_1158&hg=23&fg=31), I figured you remove circlip 24, and slide shaft 25 out of the box. But no, the breather hole is smaller than the diameter of the shaft. So now I'm sitting here wondering how the smeg I replace the shaft (6) ?? I have the grub screw ( out, but yanking on the selector shaft isn't doing anything, so I'm pretty sure I have to disassemble it all, the first step of which would be pulling out that shaft 25.. But that would mean drilling the case to open the breather hole up a little, and I'm not real keen on that idea!
While I'm here, that reminds me.. I have a whine between 3-4krpm, which gets louder under load (rolling on (OR) off the throttle).. Any idea which of the bearings that would be? I'm figuring input shaft bearing, but I wasn't sure if it would be the front or back bearing? Looking at those, it looks like it's going to be a case of heat the bearing, cool the shaft, to replace them?
Thanks,
Damien
