    The rubber is installed into the impeller centre as a cup for the ceramic part of the seal. So white side to the other side of the seal with the spring.

    When assembling the impeller {with seal parts installed} press it back against the spring with your thumbs. Hold it there, check the 2 sealing faces {cam and impeller} are level, install the copper washer, apply some low strength locking agent followed by the nut and torque to 95 inch/pound.

    Make sure the thrust washer is on the cam before fitting the impeller.

    The rubber cup goes in the impeller and the ceramic part goes in the cup and seals against the plastic/rubber
    on the spring loaded part of the seal. The ceramic is somewhat fragile, be sure it is seated properly in the rubber cup.
    The FSM can be downloaded from this site and it will be a big help in repairing and maintaning the bike.
    Look for a post from ramprat for a link to the FSM.
