    A fellow that I buy Chev truks from just broke the crank in his recently purchased Ford wrecker. It's only got 10-20k on a Jasper re-man. Any thoughts? It's a stick, and driven by many young wannabes...

    Poll; would you buy a re-man?

    My guess is either the crank wasn't magnifluxed when rebuilt or a used harmonic balancer that was damaged or worn out was used by the person that installed the motor. Or someone simply over-reved it till it blew.

    I snapped the crank on a low mile 350 Goodwrench crate motor... but when taking it apart I found the harmonic balancer was hammered on by the PO when he installed the motor. :doah:

    If it is poorly balanced it is possible... But that goes back to another root cause anyway.

    Break was at the flywheel end, near the clutch. Maybe that was imbalanced?
    I'm dying to call Jasper, but my friend may call, so don't want to stir the soup... Remember, this's a tow truck with more than 1 driver...

    Could have been routinely lugged hard, that is supposed to be very hard on an engine...

    OK, called 'em, ''5 digit" production # means at least 5-6 years old, and end of story. "Wanna' talk to sales for a new one?" Warranties up, I guess... Shame...
