Hey, just wondering if this machine failure has happened to anyone else?

We have a year and a half old Makino A51 horizontal with cat40 and twice in the last four months the pins in the spindle that hold the spindle seal rod in have broke!! And they are blaming it on use putting it in wrong! ??????? nope!

(the little rod that holds the seal that butts up to the pull-nob that needs periodic replacement)
