Pressure Lubrication: A controlled flow of clean oil to bearings for less wear and longer engine life. A high-efficiency pump in the oil pan supplies lubricant to the crankshaft and connecting rod-bearing surfaces. The Pressure Lubrication System incorporates a premium spin-on oil filter.
Splash Lubrication: A gear-driven dipper or slinger in the crankcase distributes oil to components, preventing clogging of small passages. On horizontal crankshaft engines, the dipper is attached to the connecting rod. It picks up oil from the reservoir and spreads it across bearing surfaces as the piston travels through the cylinder. On vertical crankshaft engines, a spinning gear with paddles is immersed in oil and slings lubricant throughout the crankcase.
