I knocked the old bearings out myself figuring I would ruin the grease retainers and  just order new part. I was very wrong you cant get them from bmw. My dealer told me that I do not need them. I do not care what he said bmw put them in there I want them. Does anyone know a way around this. I was going to at least use a shim to get that right but I would like to keep the grease by the bearing as well.

Hi 87100rt,
BMW discontinued fitting those grease retainers on later K's, but you could easily cut some from any thin material, maybe even a beer can......of course you would have to swig the beer first. drunken

If you need another swing arm with good bearings then drop me a PM and let me know if you need black or silver.

If you do not use the grease retainers the rear tire will move over .016 inch (sorry never got into metric). So I got the correct bearings and when to McMaster carr site and bought        their  number 2895T54 which is .002'' per side thicker than stock so the wheel will only be .004 off the other direction. But I think im gonna surface grind .002 off each shim to make them the same as they should be. Oh yea and the diameter is .075 smaller from 40mm to 1.5'' as well but will touch the flat parts on the back of the outer bearing race. I know its a little anal but I like factory specs.
