300E a couple 1994 w124wagon E320 Wagon/,1971MGB Track/Rally, MG Midget Autocross ,2000 E320 wagon.
There
should in no way be enough tension on the rod to break the collar getting the belt tension correct.Have you measured for the proper belt length?That way you won't have to tighten it beyond spec.Do you have the spec for belt tension?How much it should be able to be pressed down at the test point.

broke the first collar with the old belt. went to the dealer got the second adjusting rod/collar and also bought a new belt. be honest don't beleive it was close to being tight enough. put the tensioner in a vise and the shaft the collar attach's had no "spring" movement. not able to twist it to return to orignal spot. i've ordered a new tenioner kit. going through search's on the web last night ran across someone with the exact same problem. no luck with any repleys on the final repair.

broken serpentine belt tensioner
when it is routed properly your belt will be quiet and the water pump will flow right and the alternator will charge , please believe me ,learn from my horrible experience.
