Thread: Race motor numbers

  1. Re: Race motor numbers

    Check out the forged steel crank and the funky gray (Dow metal pistons? Maybe?)

    Thanks for the photos of the left case. Date code may be I 8? If so in this instance it indicates casting in Sept 38 and is consistent with a 39 BN.

    W/r/t "forged steel crank and the funky gray (Dow metal pistons? Maybe?)"
    Not a forged crank, it's 5 pieces like (almost) everything else, look at the nut. I once saw a WR left wheel with a very odd sprocket shaft as one-piece casting (with casting number).
    I've never seen a 4 ring 45 piston, and that looks like a pop-up dome based on height. What would look like that in 1940? Sport Scout.
