We have never experienced a total crankshaft failure in any of our engines and have only seen total crank failures as a result of hydraulicing. The problem of bottom end strength is in the lack of rigidity of the main bearing caps. Even though the caps are tied into the alloy sump via cross-bolts (turning the cast alloy sump into a stressed member), it does little to keep the tunnels in alignment when making upwards of 400+kW. We now have a range of steel main cap girdles to alleviate main cap “walk” – please contact our Sales Dept for further information.
