Whenever one of these engines undergoes a major overhaul or repair, it should have a "Start-Up" period. Please use the following guidelines to "Start-Up" engines which have been rebuilt.
1. Turn on the jacket water heaters and prelube pump system, allow oil to circulate for 1/2hour.
2. With the prelube pump system operating, rotate the engine using the baring tool for a minimum of four crankshaft revolutions.
3. Start the engine and let it idle (approximately 350 rpm) for 15 minutes to allow the engine temperature to come up. Check for the correct temperatures and pressures and check for leaks at this time.
4. Take the engine up to 500 rpm with the gear box in neutral for 5 minutes.
5. Take the engine up to high idle with the gear box in neutral for 5 minutes. Check for the correct temperatures and pressures and check for leaks while the engine is running at high idle.
NOTE: Due to the small amount of load on the engine, the temperatures will not stabilize for some time. In order to warm up the engine to "normal" temperatures, it will be necessary to add some load as follows:
6. Take the engine back to low idle and start applying load to the engine.
7. Operate the engine in gear at low idle rpm for 5 minutes. Check for the correct temperatures and pressures and check for leaks. The temperatures and pressures should begin to stabilize enough to add additional load.
8. Operate the engine in gear at 450 rpm for 15 minutes. Check for the correct temperatures and pressures and check for leaks.
NOTE: Be sure to monitor the ship cooling system temperatures at this time to ensure that the water to the engine is being properly cooled. One quick check is to watch the aftercooler/oil cooler water temperature. That temperature should not exceed 50°C (122°F) and 32°C (113°F) for fast ferry applications.
9. Operate the engine in gear at 650 rpm for 15 minutes. Check for the correct temperatures and pressures and check for leaks.
10. Operate the engine in gear at 750 rpm for 15 minutes. Check for the correct temperatures and pressures and check for leaks.
11. Operate the engine in gear at full load for 15 minutes. Check for the correct temperatures and pressures and check for leaks.
12. Slowly (over a 15 minutes time period) reduce the engine rpm back to low idle. If all temperatures and pressure are acceptable, the engine can be put into service.
The total time required for this "Start-Up Procedure" is 1 hour and 45 minutes. After the engine has gone through the "Start-Up Procedure", an oil sample should be taken. Also, at least one oil filter element from both canisters should be removed, cut open, and inspected for debris. After 100 hours of operation, another oil sample should be taken. After 500 hours of operation, all oil filter should be replaced. Each replaced oil filter should be cut open and inspected. At this time the valve "bridges" and valves should be adjusted. It is very important to adjust the "bridges" as well as the valves. Rack synchronization should also be checked after 500 hours of operation.
