(14) Restriction indicatorThe engine is an in-line six cylinder engine. The firing order of the engine is 1-4-2-6-3-5. The engine rotation is counterclockwise when the engine is viewed from the flywheel end of the engine. The engine utilizes a series turbochargers, two cooler, belt-driven compressor (if equipped), and an air-to-water aftercooler. The engine has a bore of 135 mm (5.3 inch) and a stroke of 150 mm (5.9 inch). The displacement is 12.9 L (787 cubic inch).The fuel system eliminates many of the mechanical components that are used in a pump-and-line system. The fuel system also provides increased control of the timing and increased control of the fuel air mixture. The timing advance is achieved by precise control of the fuel injector timing. Engine rpm is controlled by adjusting the injection duration.The engine has built-in diagnostics to ensure that all the components are operating properly. In the event of a system component failure, the operator will be alerted to the condition via the check engine light on the dashboard. An electronic service tool can be used to read the numerical code of the faulty component or condition. Also, viewing the flash code through the operator display or the interface may be possible. Viewing the fault code depends the engine application. Refer to the Operation and Maintenance Manual for further information on viewing fault codes through the operator display or interface.Starting the Engine
The engine ECM will automatically provide the correct amount of fuel to start the engine. Do not hold the throttle down while the engine is cranking. If the engine fails to start in 20 seconds, release the starting switch. Allow the starting motor to cool for 2 minutes before using the starting motor again.
Explosion hazard! Do not use ether! This machine is equipped with an air inlet heater. Using ether can create explosions or fires that can cause personal injury or death. Read and follow the starting procedure in the Operation and Maintenance Manual.
Customer Specified Parameters
The engine can be programmed for several customer specified parameters. For a brief explanation of each of the customer specified parameters, refer to the Troubleshooting Guide for your engine.
