I installed the Balance Masters clutch balancer (already installed the crank balancer).
When I was removing one of the four nuts on the pressure plate I noticed that the nut just spun so I used a impact to spin it off and it came right off but the problem was the bolt that holds the inside piece was loose so I pulled everything off down to the inside cover, pressed the hub out and secured that bolt with lock-tight and checked the others.
I guess it's was not a bad idea because now I know it's right and the clutch hub and basket looked brand new.
