    Hey all,
    I'm fix'n to deal with a dribble from the kicker shaft and have seen 2 different parts being used (3 if you include the factory orings) .
    SKF 9815 and Timken 240731 what's the difference between them? Is there a preference?

    Not sure of part number but I replaced my seal with an X cross section seal...which came as part of the GB rebuild kit from Mick Hemmings. Seems to be holding ok after a couple of hundred miles so far.

    I am using the SKF 9815. Installed 3 years ago and have been leak free since.

    Thanks all,
    I'm probably gonn'a order a SKF 9815 seal but I did add to my order a "quad o-ring"
    2-214/Q - 1" X 1-1/4" X 1/8" Quad O-Ring

    from a hyd supply. (side project). Now if I can figure out where I put my damn gasket paper........

    Gearguy, the 9815 goes in place of the factory oring correct??? No machine work to case, just remove bushing, install seal in place of oring, replace bushing?

    yes on what you posted BUT embed it in some RTV as it is a loose fit

    When you reset the outer cover in place, regardless of which seal you use, wrap the kicker shaft splines in masking tape to protect the seal or it won't matter which one you use. I replaced the original o-ring seal in the Titanic with the updated x-ring type, but neglected to cover the splines, so it leaked anyway. Second time, with the SKF seal, I taped he splines and no leakage now.
