    Here are the broken parts on a 15 kohler command pro
    with LESS THAN 100HRS alot less.
    Note: the main bearings and cam bearings are intact!
    Only the rod bearing seems to be at fault

    Tideman,
    I thought that also, but notice the gear they discolor when overheated. And this one is fine

    Pro-cut
    What about all of the other bearings...farther in the system....without a scratch.

    This is the only other clue.
    The gears and cover on the left are this motor, and the one on the right is from a 2000hr+ motor

    Did the inside of the motor smell of gas.

    No...just clean oil
    My reason for posting is Kohler wants to deny warranty
