Some photographic evidence that the pulleys LENIN and I bought were from a different manufacturing batch and had at least some differences.

These photos and text are from Rudy's original thread post #1 Note the wear on the rivets showing on the 10,000 mile pulley AND Rudy says that the new production will have recessed rivets.

New pulley on left, my 10,000 mile used one on the right.



Again, new pulley on left, my 10,000 mile used one on the right. Something to note is the newer production pulleys will have the rivets recessed so they are not exposed to the clutch. This was something we were well aware of during testing and with it being a less harder material, didn't affect the outcome of testing.

Now look at these photos from post #164 in that same thread . . .

These are photos of one of the newly manufactured pulleys just ready for Rudy to distribute. Note the rivets are recessed into the clutch face.



Now look at the images of my failed pulley . . . Note the wear on the exposed rivets . . . Clearly these rivets were not recessed as on the pulleys that were distributed by Rudy.



And this photo of LENIN's failed pulley . . . not such clear evidence as on mine but it appears that the rivets on his were somewhat exposed to wear too so probably not recessed rivets on his failed pulley either.



My research continues . . .
