    A .025" feeler gauge fits in with the bolt tightened up, the tang measures @ .027" so that is an .002" interference.
    IMO that holds the spring tangs firmly in place.
    This is great information, thanks. Interestingly, I do not measure a gap in the relief area of .025. The interference make sense though.

    By the way, what are the tangs for?
    I want to be unique, just like everybody else.

    They hold the fwd friction plate in position

    Can anyone offer opinion as to the cause of the black scoring on my R1150RT housing cover? This bike did have input shaft and clutch hub failure. Could this be further evidence of misalignment? I'm assuming I should replace this part also. What's another $186 at this point?

    nothing remarkable, in my opinion, on the corresponding wearing surfaces of the clutch plate

    Aside from being very slightly conical, is it warped? depression in the black area? Is the flywheel warped? (I understand it is not.) How about those three flexplates around the perimeter? Any cracks in them?

    FWIW some years ago I saw a pix of similarily burned flywheel face on an oilhead that I attributed to friction heat from the clutch disk being dragged around the flywheel? Maybe not?

    Neil, I can't tell if it's warped. There is definitely a pattern of wear from outside to in (see photos) There also does appear to be a slight depression in the black area and also the metal feels rough. I do not see any cracks in the casting of housing plate or anywhere in the pressure plate. Clutch Housing 3.jpghousing cover2.jpg

    My attempt to determine if the flywheel is warped was inconclusive with the use of a straightedge.

    Those marks are from heat - sliding the clutch

    Is this wear(worn circle center frame) on the outside of the clutch housing cover normal?

    Thanks GSAddict. Sliding meaning either incomplete engagement or disengagement of the clutch for extended periods?

    Is the outside to interior wear pattern normal? Would you recommend replacing this cover?

    Every one I have taken apart looked like that. BMW recommends that the whole assembly gets replaced so the new clutch plate will wear properly.
    On all the client bikes I have done that because of comeback potential. (client ultimately made the decision)

    On my own machine (256,000km) I ignored it and just replaced the disc. No issues whatsoever over 3 discs.
    Disc 1 @ 75,000km - to fix trans oil seal leak (replaced stock input shaft as well)
    Disc 2 @ 152,000km - replace stock input shaft with custom longer unit
    Disc 3 presently running
    I am still running all the other original clutch parts. (including the slave cylinder)
    All I did to the friction surfaces was roughen the with an orbital sander & 100 grit emery sheet.

    Basically starting on a hill loaded up and sliding the clutch too long to get going.
