    Every time you do an oil change.
    Just pop off the front air intake tube. Grab hold of the nut and "feel" for excessive movement up and down (bush bearings) PLUS in and out (thrust bearing).
    At 100 hours, strip it down to it's birthday suit.

    Your mainly worried about the impeller running into the housing. It's more of a "gut feel" kinda thing.

    If your worried, strip away.

    I think you should be good if it's a 13pound wheel or less.

    15psi and up (plus revs over 8600rpm) wears the bush bearings and thrust plates expotentially.



    Just my thoughts, but I'm sure I'll be corrected by someone.
