    Trying to figure out which crank I have. The serial number is 28939

    1. CalliesAdmin says:

      Do you have any images of the crank? The serial number, if it is a Callies, is quite old and not in our electronic system.

        The serial number you have provided for us is for a 2005 SB Magnum. We cannot give you a current value of the crank, because there are so many factors, like how often it has been used and how it was used in that time. If you’d like to talk to a tech or sales team member please call us at 419-435-2711.

  15. Wayne says:

    I was wondering if you could please provide clarification on the bolt size , bolt length and bolt thread type that should be used to connect the flywheel to my Callies Magnum Crankshaft.
    Currently the engine is bolted to a stand and I have very limited access to the area. Prior to removing the engine I wanted to be sure I had the correct bolts available.

    The engine is a BBC 540 CID and the number stamped on the crank is 154949 ( See pic)

  31. Chad de boyce says:

    Hi my crankshaft (which is a beautiful work of art)
    has the number 104710
    Can you tell me what the weight of the crank is
    What Rods to use (to match the beauty) of its monster stroke
    And include any specs of the crank or weights of rods or pistons for balancing use.
    Or whatever you recommend every detail no matter how small may be helpful and is welcome
    The bob weight break down, what balancer or flywheel that would be a good choice (for such beauty as this)
    The horse power rating or limit of the great beast

    And …
    Was it indeed made by or touched by the hand of God ?
    Because liken to all his great works it is as strong as it is perfect (and it may yet walk on water)
    Thank you
