  • Question about B-body P.S. resevior Large O-Ring Seal OuterInner Diam. (~4.5" )

    Does anyone know the diameter width of a typical B-body
    power steering pump Large-O-RING seal. I seem to recall
    its the P.S. steering resevior (**on TRW units and possibly
    on FEDERAL-THompson units ) has a Inner Diameter
    a little larger than 4.5" (possibly 4 9/16 or 4 5/8). Which
    obviously Implies the O-RING needs to measure about
    4 5/8 outer diameter.


    The Reason being is the Most B-body car owners always joke
    about the proverbial 'LEAKING power steering pump".


    ***Well, it doesnt have to be that way just because most $50 cost
    P.S. Steering Gasket kits dont have a Correctly sized Large
    O-ring, and hence still alow "Fluid to leak thru the shell".


    **It seems going out to a INdustrial seal business is the way to
    go (for example www. motionindustries.com or ,
    to just name a '"FEW").

    Any comments .. I'm much obliged....
