[MBZ] Eating belts

My '95 E300 with OM606 engine has decided to eat the serpentine belt. The only recent change is the new (rebuilt) alternator. How do I determine if the alternator is the culprit? -Max -- Sent from my Android phone with K-9 Mail. Please excuse my brevity. ___

My guess is that the old alt wasn't putting much of a load on the system, and the old belt was on it's last legs. New alternator allows full charge current and puts more stress on belt, belt snaps. Long story short, replace belt and then see if it happens again. Worst case, keep a spare belt in

Does the alternator rotate freely and smoothly (without wobble) by hand? Do the other pulleys (idler, water pump, pwr. steering pump, A/C comp.) rotate properly without binding. When you sight down the edge of belt across all the pulleys, are all the pulleys in same plane - properly aligned

I know it' possible to put the water pump pulley on backwards, and if you do it will strip off a couple ribs on the belt. Might be true of the alternator pulley as well. It will be obvious if this is the case, one side of the belt will leave a gap on the offending pulley opposite the gap

When the alternator in my 300SDL went bad it would spin freely by hand but would occasionally lock up and cause the belt to jump off. I knew because the 2nd time it sheared the key. It is possible a rebuild could do the same. Always carry spare belts, tools, and a can of red bull. -Dave Walton
