Wellllllll, I got into some serious deep mud and in trying to keep my 33" Yokohama mudders spinning I overrevved the engine and spun the main bearings and a couple rod bearings. I can get that taken care of easy enough, but my oil pump chain snapped in 2 places. WTF? How could the chain break in two places at once? Does anyone know what could have caused that and what I need to check for damage besides the sprockets?
