[AT] Weird broken crank(not the 430!)

[Dennis Johnson]

Spencer,

I have seem brakes that look like this on some shafts.

If my memory is correct it was on some shafts that were driven by new electronic controlled engines. They used to work fine on older engines that had mechanical controls. Theory is that the faster response of electronic fuel controls caused torque spikes that loaded the shaft differently.

Thanks
Dennis

I have a small Briggs that broke a crankshaft yesterday. The weirdest thing I've ever seen. Have you ever seen a crank break and leave this type of a star pattern on both ends?
