Cat 3406C engine offers superior Fuel efficiency. High fuel injection Ether starting aid comes standard on the lugging performance, fuel efficiency pressures ensure proper mixing of fuel 16H to help ensure engine starting in and reliability. The six-cylinder engine and air. This high injection pressure, the extreme cold. The system monitors is turbocharged and aftercooled with a coupled with the precise metering and engine coolant temperature to prevent high displacement-to-power ratio. This timing of the fuel injection, results in ether from being injected into a hot large displacement produces better superior fuel efficiency and reduced engine. lugging capability, lower internal emissions. High compression ratios stresses and extended component life. ensure dependable cold-starting performance and low emissions. Superior lugging performance. High torque output and high torque rise make Extended engine life. The large bore- the 3406C engine very responsive. The stroke design and conservative power engine’s lugging capability allows it to rating help minimize internal stresses pull through sudden, short-term and increase component life. A wide increases in loads, reducing the need to journal crankshaft with a large rod downshift. As a result, the operator can bearing surface significantly increases maintain desirable working speeds, bearing life. which means the work gets done faster. 4 Power shift transmission.

The dual air Inching capability. Low pedal effort and capability. system also has a large reserve for excellent modulation provide precise stalled-engine braking. Direct drive delivers superior fuel control of machine movements when efficiency and better “feel” of blade using the inching pedal. Oil-disc brakes. Caterpillar designs and loads, material hardness and ground builds multi-disc brakes that are speed. completely sealed and adjustment-free. The brakes are oil-bathed, air-actuated Gear selections. Eight forward speeds and spring-released. They are located at and eight reverse speeds give the each tandem wheel to eliminate braking operator a wide operating range. With loads on the power train and to reduce four gear selections below 10.6 km/h servicing time. The large brake surface (6.6 mph), the operator can precisely provides dependable braking capability match working speeds to job conditions and long life before rebuild. for maximum productivity in earthmoving and mining applications. A single lever controls direction, speed and the parking brake. 5 Hydraulics Balanced hydraulics deliver consistent, precise and responsive control. 1 Lock valve 1 1 2 Line relief valve 3 Blade float detent 2 3 Power on demand.
