Higher mile stm weights warning

[Big_Phil]

Look at how the washer is worn on the right side in the pic. The weight did that, and it wouldn't do that if the bushings were not worn. I've seen worn arm bushings in a winder before and this is what happens, it wears the plastic washer out on one side.

I get what you are saying, however, I moved these weights and rollers from 1 clutch to a newer one 1000-1500kms ago. The washers had no wear, the bushings in the weights had no wear. I will check all the other ones tho, appreciate the tip.

The 60y weights are wide, very wide. I’ve seen washer wear like this using these weights in Apes with even the slightest bit of bushing slop in the cam arm. The adjustability of these weights is amazing, but they’re not perfect either.

Honestly, these clutches have been good to me. I have my original primary with 12000kms, just the spider buttons were a little sloppy. Pretty mint other than that. I put a new primary on just because I had it lying around, and 1500kms later a weight breaks.

Was the new primary you installed a winder primary? And was that the one shown in pic?

Ya its the one in the Pic. It wasn't brand new, was a low mile one I bought, and put around 1500kms on it + whatever it had when I got the clutch.

Looking at the wear on the right roller washer, it is plain to see the bushing was worn/shot in the arm and not running straight/true on the roller. May have gone many more miles had the arm bushings been replaced.

You are correct on the bushings. They were ok 1500kms ago, but the bushing on the broken weight is sloppy. Another weight is just starting to wear and 1 still looks good. I’ll be replacing bushings every season now in the weights.
