BEARING 5I7796 - Caterpillar

These engines are in-line six cylinder engines. The engines have a firing order sequence of 1, 5, 3, 6, 2, 4. The rotation of these engines is counterclockwise when the engine is viewed from the flywheel end of the engine. These engines utilize a turbocharger and an air-to-air aftercooler.The Electronic Unit Injector system (EUI) eliminates many of the mechanical components that are traditionally used in the fuel injector assembly. The EUI 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 injection timing. Engine speed is controlled by adjusting the injection duration. The engine has built-in diagnostics in order to ensure that all of the components are operating properly. In the event of a system component failure, the operator will be alerted to the condition by a check engine light. The check engine light is located on the dashboard. An electronic service tool can be used to read the numerical code of the faulty component or condition. Also, the cruise control switches can be used to flash the code on the check engine light. Intermittent faults are logged and stored in memory.Starting The Engine
The engine's ECM will automatically provide the correct amount of fuel in order to start the engine. Do not hold the throttle down while the engine is cranking. If the engine fails to start in 30 seconds, release the starting switch. Allow the starting motor to cool for two minutes before the starting motor is used again.
Excessive ether (starting fluid) can cause piston and ring damage. Use ether for cold weather starting purposes only.
Cold Mode Operation
The ECM will set cold mode when the coolant temperature is below 18 °C (64 °F).Cold mode is activated five seconds after the start of the engine. During cold mode, low idle speed will be increased to 800 rpm. After 60 seconds, the engine speed is reduced to 600 rpm. Engine power will be limited until cold mode is deactivated.Cold mode will be deactivated when the coolant temperature reaches 18 °C (64 °F).Cold mode varies the amount of fuel that is injected for white smoke cleanup. Cold mode also varies the timing for white smoke cleanup. The engine operating temperature is usually reached before the walk-around inspection is completed.After cold mode is completed, the engine should be operated at low speed until normal operating temperature is reached. The engine will reach normal operating temperature faster when the engine is operated at low speed and low power demand.
