The flywheel pictured below has 5k miles on it along with a new pressure plate, clutch disc, throw out bearing, etc.
Clutch slips under full immediate throttle from a healthy four. What are all the "spots" an indication of? Attached image(s) |

I don't know how it is supposed to be, but here is what I found.
I placed a straight edge on the flywheel and a few of the bolts catch it just so ever slightly as the straight edge is slid across the face of the flywheel. Letting the straight edge "rock" on one of the bolts, I'd guess it protrudes a few thousands at the most. But as the photo shows on the clutch disc, there is no apparent wear in the area the bolts would contact. Plus that surface is on the back side of the disc pad. By the time it would touch the rivets would be in the flywheel surface. I'm thinking that maybe the bolts were like that originally? I can't remember. Should I hand file them down a bit or just leave them alone? Are you referring to the "tangs" on the pressure plate that contact the release bearing? There is a slight marking on them but almost no visible wear. I do know that the clutch cable had a good looseness that was easily moveable between the end of it's housing and the clutch fork. I will take measurements of the flywheel depth tomorrow and take a close look at how the pressure plate snugs down and moves the tangs as it is tightened as some others have suggested. Maybe you're right and the specs on this flywheel are off. This story may not be over yet. Damn Clutches. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) |
