My 1993 350l 4x4 clutch cover just started touching the clutch while I was riding it yesterday. The clutch is rubbing on the top and bottom of the cover in the same area. I have read about the covers warping. How can I really tell? and is it possible the clutch could be coming out to far and touching the cover. I have been using the machine to tow a brush hog around this weekend. After a long while I noticed noise from the cover at idle. Give it a little gas and its gone. The longer I rode it the worse it got.
