  • Replacement Crank P/N Difference?

    I bought a NOS 224 V-8 crank from SASCO last summer, and yeah, I measured it and it is indeed the short-stroke crank I wanted.

    The forging number on that cool Stubebaker box is 535134.
    Studebakerparts.com gives the number as 533439.

    What's up with that?

    In the automotive industry......
    Casting numbers, forging numbers, and part numbers are 'usually' all different.
    Some manufacturers have different OE 'production' part numbers (from OE 'replacement' part numbers.
    Some OE's change their OE 'aftermarket' part numbers on a regular basis to make it harder for 'aftermarket' replacement parts companies to make cross references for their products to be used.
    In the case of Studebaker, it might be easier to chase down because a lot of this research has already been done by stubborn Stude enthusiasts and vendors[]

      My guess is if you look on the crank you will find the 533439 number on one of the forward counter weights and the number on the box may be different because there is a crank bolt, washer, etc., and the reason for the different number. This is my GUESS so this may not be the correct answer.

        Ah, yasss...I fingered it was something like that--the above P/N came off the label on period-piece box[8D]

        A long serial number-like string of numbers were not cast, forged, or stamped into the crankshaft itself, but there were some numbers and other "identifiers" (that scientists isolated at Area 51 would understand):

        [u]Rearmost counterweight</u>
        Stamped on machined surface-- T [u]4</u>7
        Cast-in on rough part-- V2
        Stamped on rough part-- 6TA

        [u]Next-to-last counterweight</u>
        Stamped on machined surface-- &6

        [u]Counterweight 5/6 next to main #4</u>
        Stamped on machined surface-- 3

        [u]Second Counterweight from front</u>
        Stamped on machined surface-- 12 3

        [u]Front Counterweight</u>
        Painted color Orange

        Inquiring minds gotsta know[8] What does it all mean?

          On most cranks I've seen there is a number CAST on the second counterweight (between number two rod and number two main) on the SIDE of the throw.

          Sounds like you looked it over pretty thoroughly but check this area just to be sure.
