The configuration of the twin-cylinder in the 90º (V-arrangement) offers compactness, and is lightweight. Strong crankcase reinforcing ribs prove this engine is built with durability in mind.
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
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.
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 main bearing support on PTO side of crankshaft minimizes shock under heavy loads.
Large-capacity air cleaner with dual elements enhances reliability.
Special machining process allows a support bearing to be placed into the block that can be removed for service.
The filtering properties of the paper composite mesh, located inside the filter, screens out the dirt particles before returning oil to the engine.

This design provides consistent oil pressure to the critical engine components. An air-cooled engine needs cool oil temperatures for long engine life.
Solid lifters for dependable cold-weather starting.
The high strength steel ensures lasting longevity even during the harshest conditions. The rocker arms utilize a large contact area to the valve stem for greater durability.
Advanced three-ring oil system. The special three-piece expander oil ring is designed for better sealing and less oil consumption.
Camshaft gears and lobe assembly are cast together in one piece for a stronger assembly. The camshaft gears are a helical design for quieter and smoother operation. Also, the support bearing surface is a large at 20mm.
Special machining on cylinder head allows the oil seal to be placed around the valve guide. This seal reduces oil consumption and is replaceable for service.
This needle roller bearing on the back side of the governor gear provides smooth and precise operation for the governor gear and flyweights assembly.
This low oil pressure switch can be wired to the optional key switch control box or another customer-supplied low oil warning light configuration.
