BUCKET PINS KEEP COMING LOOSE

[jardolina]

I SEE SOME OWNERS HAVE SAME PROBLEM WITH TAPERED PINS BECOMING LOOSE AND FALLING OUT MACHINE ONLY HAS 622 HOURS
HOWEVER I SAW NEW 333 AT CONEXPO AND PINS ARE STRAIGHT WHITH RETAINING BOLTS WAS TOLD BY FACTORY REP RETROFIT KIT IN THE WORKS
ANYONE EXPERIENCING SIMILAR ISSUE?
