Features & Benefits

Dynamically balanced crankshaft

• Crankshafts are formed from heat-treated ductile iron

Forged-steel connecting rods

• Unique 45-degree design permits the use of a larger crankshaft connecting-rod bearings for increased durability

Self-adjusting Poly-vee Fan Drive

• Self adjusting, eight-groove, poly-vee fan drive provides multiple fan drive ratios and fan heights that can be matched to specific application requirements
• Poly-vee design provides more than twice the drive capacity of comparable vee-belts

Replaceable Wet-Type Cylinder Liners

• Provides excellent heat dissipation
• Precision machined for long life

Either-Side Service

• Entire installation and maintenance simplified and convenient by providing dipstick and oil filter options on both sides of of the engine

500-Hour Oil Change (Tier 2 only)

• Customers save significant costs on oil, filters and labor with a 500-hour oil change interval

Standard Gear Auxiliary Drive

• Standard gear auxiliary drive produces up to 50 hp (37 kW) for gear-driven accessories

Mounting Points

• Standard front and side mounting points provide easy installation and application flexibility

Electronic-Controlled Rotary Injection Pump (Tier 2 only)

• Electronic-Controlled rotary injection pump distributes the precise amount of fuel required by each cylinder at exactly the right time
• Electronic controls monitor engine speed and load to determine fuel timing

SAE J1939 Standard Communication Link

• Industry standard, which provides an interface with vehicle systems, like the transmission, hydraulics and various accessory drives minimizing machine complexity and reducing the installed cost

Optional Engine-Balancer Shafts

• Provides smooth engine operation

Features & Benefits - 4 Valve Engines

High Power Density

• High power density allows an OEM to use engines of a smaller displacement, reducing installed costs

Glow Plugs

• Glow plugs and pilot injection provide superior cold weather starting

Common Block

• 4-valve engines share a common block with 2-valve engines for application ease

4-Valve Cylinder Head

• New cylinder head with 4-valve design provides increased air flow for superior performance

Exhaust Port Liners

• Exhaust port liners result in best-in-class heat rejection

High-Pressure Common Rail Fuel System

• With the HPCR, the fuel pump sends constant pressure into a common rail, supplying each injector with constant pressurized fuel that's available when the electronic injector opens
• New injectors are vertical and centered over the pistons, which allows for improved burning of fuel

Centered, Vertical Injectors

• Engines burn cleaner, resulting in lower emission and improved fuel economy with the aid of vertical injectors

500-Hour Oil Change

• Customers save significant costs on oil, filters and labor with a 500-hour oil change interval
