This
design provides consistent oil pressure to the critical engine
components. An air-cooled engine needs cool oil temperatures for long
engine life.
Forged high-carbon steel crankshafts 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 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.
Long engine life is ensured by placing support "ribs" at strategic
locations to insure torsional loads, as well as crankshaft support
loads.
Large gasket surfaces, thick aluminum bracing and large bearing surfaces add up to equal a strong cover.
This dual-stage air cleaner element enhances the reliability and longevity of this engine.
