    I'm re-assembling my 425 and don't want to use the original crank packing material to seal the crank in the timing cover. Can someone provide a part number for a proper seal.
    Thanks

    Front seal for your 425,
    Federal Mogul #474272 or CR19786 neoprene approx. $12.00
    National #450446 (Some builders say this is the best seal to use.)
    Should be available at any good parts store.

    Good luck,
    John

    There are three stakes in the housing-120 degrees apart-to hold in the steel rope retainer-sometimes it takes a little careful dremel grinding to bring the upset material down for the new type seal to seat happily-good luck

    seal direction

    Make sure when you put the seal into the housing that you place it with the flat against the outside of the housing. this seal is made to go in from the front and since your location is from the inside, it needs to be placed in that direction from the inside. :Smarty:
