Sorry for taking so long to respond on this. Thanks Ted and Steve for the information regarding the harmonic balancer. You have provided some valuable information.
My first balancer failure occurred a year after a (factory?) rebuilt motor was installed. The balancer and radiator were replaced by a non-Mercedes shop (happened out of town). A year after that replacement, it failed again. This second time it was replaced by an independant local Mercedes specialist shop. That was 3 years ago.
I'm wondering if it would be a prudent course of action to replace and retorque the bolts every year or so? Any comments?
