Information:
Note: When electric power is cycled, the electronic thermostat cycles. This process makes a unique sound that is a normal sound for a start-up.Manual Starting
For initial start-up of a new or rebuilt engine, and for start-up of an engine that has been serviced, make provision to shut the engine off should an overspeed occur. This may be accomplished by shutting off the air and/or fuel supply to the engine.
Do not start the engine or move any of the controls if there is a "DO NOT OPERATE" warning tag or a similar warning tag attached to the start switch or controls.Ensure that no one will be endangered when the engine is started.
Perform all of the procedures that are described in this Operation and Maintenance Manual, "Before Starting Engine" (Operation Section).
Do not engage the starting motor when flywheel is turning. Do not start the engine under load.If the engine fails to start within 30 seconds, release the starter switch or button and wait two minutes to allow the starting motor to cool before attempting to start the engine again.
To start an engine with the control panel, press the "Start/Stop" switch.For additional information on the control panel, refer to this Operation and Maintenance Manual, "Control Panel".Starting the Engine After an Overhaul or Major Repair
Use the following guidelines for operation and maintenance after an overhaul or a major repair. This procedure will ensure that the engine is functioning correctly. The procedure for start-up requires approximately 1 hour and 45 minutes.
Perform the procedures that are described in this Operation and Maintenance Manual, "Before Starting Engine" topic (Operation Section).
Operate the jacket water heaters and the prelube pump. Allow the lubricating oil to circulate for 1/2 hour.
During prelube pump operation, use the barring device to rotate the crankshaft for a minimum of four revolutions.
Start the engine. Operate the engine at low idle rpm for 15 minutes. Allow the engine temperature to rise. Check for the correct temperatures and pressures. Inspect the installation for leaks.
Do not apply the load. Increase the engine rpm to high idle rpm for 5 minutes. Check for the correct temperatures and pressures. Inspect the installation for leaks.
Shut off the engine. Remove the side covers. Measure the temperature of the bearings with a 123-6700 Laser Infrared Thermometer. Ensure that the large ends of the connecting rod bearings moves freely. Visually inspect the piston skirts, cylinder liners, and bearings for any abnormal signs such as flaking and/or scuffing. If the appearance of the components is satisfactory, install the side covers.
Start the engine. Operate the engine at low idle rpm for 5 minutes. Check for the correct temperatures and pressures. Inspect the installation for leaks.
The temperatures will not stabilize for some time because the engine will be operating without a load. To warm the engine up to "normal" operating temperature, increase the engine rpm to high idle rpm for 5 minutes. Check for the correct temperatures and pressures. Inspect the installation for leaks.Note: Monitor the cooling system temperatures in order to ensure that the water to the engine is being properly cooled. Observe the water temperature of the aftercooler and oil cooler system. The temperature should not exceed 50 °C (122 °F).
Apply 25 percent of the rated load. Operate the engine with this load for 15 minutes. Check for the correct temperatures and pressures. Inspect the installation for leaks.
Increase the load to 50 percent of the rated load. Operate the engine with this load for 15 minutes. Check for the correct temperatures and pressures. Inspect the installation for leaks.
Increase the load to the full rated load. Operate the engine with this load for 15 minutes. Check for the correct temperatures and pressures. Inspect the installation for leaks.If all of the temperatures and the pressures are acceptable, the engine can be returned service.Maintenance Procedures After an Overhaul or Major Repair
After the initial start-up, perform the maintenance that is listed in Table 1. See the maintenance procedures that are in this Operation and Maintenance Manual (Maintenance Section).
Table 1
Maintenance Procedures After an Overhaul or Major Repair
Interval Maintenance Procedure
Following the start-up procedure Obtain an oil sample and analysis.
Remove at least one oil filter element from each oil filter housing. Cut the element open. Inspect the filter material for debris.
100 operating hours Obtain an oil sample and analysis.
500 operating hours Replace all of the oil filter elements. Cut the used elements open. Inspect the filter material for debris.
Perform the procedures that are described in this Operation and Maintenance Manual, "Engine Valve Lash - Check/Adjust" topic (Maintenance Section). Starting the Engine After a System Generated Shut Down
Do not perform any procedure in this Special Instruction until you read this information and you understand this information.This Special Instruction provides a procedure for inspecting the engine after a system generated shutdown.The cause of a system generated shutdown must be corrected prior to an engine restart. Severe engine damage may occur if the problem is not corrected. In some cases, the cause of the shutdown may be obvious and easily corrected. In some cases, a visual inspection may not reveal the root cause of the shutdown. The engine must be started in order to determine the root cause.The time that is required for the start-up procedure is approximately 1 hour and 45 minutes. It is important to determine the root cause of a system generated shutdown in order to avoid engine damage. This procedure is a method for an engine restart when the root cause of the system generated shutdown cannot be determined by visual inspection alone.Note: If the engine is shut down by the oil mist detector, refer to the OEM of the oil mist detector. See this Operation and Maintenance Manual, "Product Description" for OEM website information.The following conditions can cause a system generated shutdown.
High aftercooler and oil cooler water temperature (inlet)
High jacket water coolant temperature (outlet)
High fuel temperature (inlet)
High inlet manifold air temperature
High crankcase pressure
High engine oil temperature
Low engine oil pressure
High engine oil filter differential
