Forged High Carbon Steel Crankshaft  
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.

Large Ball Bearing on PTO Side  
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.

Large-Capacity Air Cleaner Element  
This dual-stage air cleaner element enhances the reliability and longevity of this engine.
