O.K. I guess I'll chime in here. My idler was wacked from the get go. I took it apart and miked the bushings and the steel sleeve. None of these parts were completely round. One bushing measured 1.250 x 1.252 i.d. The other was 1.250 x 1.254. The sleeve I cant remember exactly, but one end of it was only 1.242. I reassembled it and oriented the parts to reduce play. This helped. I called Calmini and they sent me a new sleeve, no charge. The new sleeve is 1.252, and perfectly round. I had to just barely tap it in. I now have no play whatsoever. I have very few miles on this so no news on how long it will last.By the way, my bushings are pressed into the arm. I suggest checking your sleeve before reassembling with new bushings.
