Cast-iron cylinder liners enhance reliability and extend engine life. The cast-iron cylinder liner has much better wear characteristics than the softer aluminum that surrounds it, making engine life much longer than if the piston is in contact with the aluminum cylinder wall.
Forged high-carbon steel crankshaft provides maximum reliability under demanding loads, thus providing longer engine life.
The drop forging process increases the strength and durability of the crankshaft by re-aligning the molecules in the steel. This process hardens the complete crankshaft.
Most engines use cast-steel crankshafts that have induction-hardened surfaces only a few microns deep.
This needle roller bearing on the back side of the governor gear provides smooth and precise operation for the governor gear and flyweights assembly.
Large-capacity air cleaner with dual elements enhances reliability.
Longer engine life is achieved by filtering out large dirt with the outer urethane foam element, and the densely pleated large diameter inner filter for harsh environments. This combination provides a high degree of capacity to extend service intervals to protect the engine.
Large main bearing support on PTO side of crankshaft minimizes shock under heavy loads.
This design provides consistent oil pressure to the critical engine components. An air-cooled engine needs cool oil temperatures for long engine life.
