Default Blade grips slide left to right...

So I am about to take apart the head on a used 600 N I just bought, and I noticed some movement on the blade grips. The movement is left to right as if the blade grips were loose, and the feathering spindle is moving through the hub from left to right(grab both blade grips and slide them from left to right in the hub) and appears to be about 2mm or so, maybe less. Is this acceptable, and if not, do I need to add shims, or is this an indicator of bad bearings? Is it spacers, dampers, or thrust bearings?

It sounds like there are spacers missing (I am interpreting what you described as the spindle sliding through the head).

If you bought it used, please take it apart and check it (as a matter of fact, take the whole thing apart and check it to make sure that it was assembled properly, that all the fasteners are clean and threadlocked).

Did the instructions come with it?
