    Fleetwin,
    The lower seal was intact when I replaced it. There was a small amount of rust on the crankshaft lower seal area. The upper bearing showed no rust. I replaced the upper crank seal and the bearing o-ring.
    Thank you.

    Be careful, many of the powerheads of that era did not use an oring on the upper bearing, adding one will mess up the recirc system. You mentioned there was some rust on the bottom of the crank, was it rusty where the lower seal rides? Did this powerhead look like it had been apart before?
