So if your shaft was misaligned it still is. Correct ? btw how long did it take the first shaft to get destroyed?
It did not get as far as destroyed, see post#167

I am in the middle of a spline lube. My plan is to replace the clutch disk, plate and cover, but keep the existing clutch housing. The housing seems to be flat, not perfect, but close. The housing appears to be a cheap piece of stamped steel. Beats me why it lists for $351. In any case, when I assemble the plate and cover with the housing, I noticed the cover will not sit flat upon the housing. There are 3 tangs that hold the clutch plate to the clutch cover. Each of the 3 tangs is located next to one of the 6 cover bolts. The tang is squashed between the cover and the housing. The 6 bolts are beside ?pads? on the bottom of the cover where it is supposed to contact the housing. Due to the thickness of the tangs, the ?pads? will not sit flush with the housing. The 3 pads without a tang next to them have a gap underneath them. As a result, the cover will rock back and forth when pressing above any of those 3 pads. When I swap the clutch plate and cover with the originals, it?s the same. The mount points of the housing cover where the tangs contact, are slightly recessed from the rest of the housing, but clearly not deep enough. When the cover is bolted down tight to the housing something in the assembly has to bend and deform in at least 3 places. I have to suspect that the entire clutch assembly has a slight wobble. I wonder if anyone else has noticed this as well?

There is a relief in the metal to allow for the tang just to the left of the left threaded hole
There is thin line visible where it was pressed.
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.
By the way, what are the tangs for?
What's the dark spot at the 12 o'clock position?
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?
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?

Those marks are from heat - sliding the clutch
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. View attachment 44351View attachment 44352
My attempt to determine if the flywheel is warped was inconclusive with the use of a straightedge.
Yes that is done for balancing purposesIs this wear(worn circle center frame) on the outside of the clutch housing cover normal?

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