The vibration damper on my 7130 failed today. Pulley moved forward far enough to throw and ruin the fan belt but is still jammed pretty tight so that I can't push the pulley back far enough to remove it. I haven't got the studs loose yet. Supposed to be 18 mm but I can't get an 18 mm socket on. A 19 fits loose.
How long do these dampers usually last? Did I miss the warning signs? I'm at 6400 hours and it worked perfect right up til the belt came off. Lucky I saw the alternator light come on and had to get towed home (by a tractor ten years older and 700 higher hours on the meter)
