    Frank, you should never assume I know anything 🙂
    I did not know the pan could be dropped without
    pulling the power head, but I know now!
    seems that the 10th edition manual is lacking.
    To pull the power head it just says pull all the bolts necessary. 🙁
    Someone mentioned in another thread that some of these
    o-rings were replaced with "square" o-rings on some models,
    and only on the top side and not the bottom side, or visa-versa.
    What’s up with square o-rings.
    I looked at some on McMasters Carr, and it mentioned they are
    used in "static" installations, so not sure why they’d be better
    for Johnsons?
    Thanks!

    quote FrankR:

    The o-rings you speak of—-The upper one and one of the lower ones are inside the carbon seal. No need to pull the powerhead to access the upper one. But of course the powerhead does have to come off if you want to access the lower one. The second one on the lower end is around the bearing, and the powerhead has to not only come off, but also come apart to get at that one—-not a normal service requirement.

    You know those lower pans can be removed without removing the powerhead—don’t you?

    Prepare to be boarded!
