Yamaha - Oil Pump Assembly Engine Lubrication Component 6C5-13300-01-00. Overview. When it comes to protecting an engine, oil flow is everything, and this pump is right at the center of it. It keeps oil moving through the system so internal parts stay lubricated and don't wear out prematurely. I've seen engines get noisy or run hot when oil flow starts dropping off, and it doesn't take long for damage to follow. Keeping a solid oil pump in place is just part of keeping the motor healthy and reliable..
