603 diesel engine - acc belt tension adj or shock?
I have replaced the accessory belt shock annually on my 350 SDL ... it sounds like it is shot again.
Could it be that I should have replaced the accessory belt tension adjuster? It looks like it absorbs part of the vibration load and then allows some of it to go to the shock ... am I on the right track?
If I am, I should replace both at the same time, right?
Indications are a bit different this time ... usually, it just starts a low pitch rattle. This time it sounds more like a "tinging" noise that I have read is typical ... scary sounding (like chain rails coming loose).
