    Question Grasso RC411 diameter shaft at the shaft seal point (driver pin)



    Hi guys,

    i have a little question.
    i have the service manual and it gives me the diameter for the shaft journals.
    but what i want to know is the correct diameter at the point of the shaft seal(at the driver pin) i measured it at 85.00 mm but wanna know if this is correct and what the margins are seeing that its not in the manual at all.

    thanks in advance for taking the time to help.

    I have some information, but not that.
    In manual "0" ring in shaft seal has ID of 84.95, so 85mm would be pretty close.
    The whole shaft seal area should be same dimension all along shaft, not only next to pin.
    Where "0" ring seals would be most important.

    Hopefully someone has it, but is not a wearing surface under normal circumstances.
