COVER GP-CYLINDER HEAD 5218085 - Caterpillar

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.
Refer to Locomotive OEM publications on starting the engine.For further information concerning the EMCP 3, refer to this Operation and Maintenance Manual, "Electronic Modular Control Panel 3 (EMCP 3)" topic.Starting the Engine After an Overhaul or Major Repair
Use the following guidelines for operation and maintenance after an overhaul or a major repair. Using the guidelines will ensure that the engine is functioning correctly. The procedure for start-up requires approximately 1 hour and 30 minutes.
Perform the procedures that are described in this Operation and Maintenance Manual, "Before Starting Engine" topic (Operation Section).
Operate the jacket water heaters, if installed. Run the prelube pump and allow the lubricating oil to circulate for 10 minutes or less. To operate the prelube pump without starting the engine when the starting oil pressure is reached, perform the following: Access the service override file in Cat electronic technician (ET), override the prelube pump to ON.Note: Running the prelube pump for more than 10 minutes at a time risks overheating the pump electrical motor.To operate the prelube pump without starting the engine when the starting oil pressure is reached, perform the following:
Access the override tile in Cat electronic technician (ET)
Override the prelube pump to ON
During prelube pump operation, use the barring device to rotate the crankshaft for a minimum of two revolutions.
Start the engine. Operate the engine at low idle rpm for 15 minutes. Refer to this Operation and Maintenance Manual, "Engine Operation" for the procedure on starting and running the engine at low idle. 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 move 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 to ensure that the water to the engine is being properly cooled. Observe the water temperature of the aftercooler
