1. Verify that engine is filled with break in oil. The break in oil shall be approved by the engine manufacturer for 100 to 500 hour run time, John Deere Break-In Plus or approved equal. Pull a sample of the clean lube oil prior to the load test to be used for reference.
2. Perform hydrostatic test on water jackets to ensure that water seals and water jackets are watertight. Test report shall indicate pressure at which test was made and the results.
3. Connect engine coolant piping to radiator or heat exchanger. Note that all engine coolant circulation must be performed by the engine water pump without the benefit of any external pump or pressurized system.
4. Install thermometer to monitor coolant return temperature entering the engine for comparison against the coolant discharge temperature.
5. Connect engine air piping to charge air cooler.
6. Connect engine and generator to the associated control wiring junction box.
E. Engine Pre-Tests: Prior to the 8 hour load test perform the following tests:
1. Power up the ECU and program as shown in the typical payload file in Attachment A. Connect the ECU to an analog throttle input and verify that it is correctly responding including idle operation at input less than or equal to 0.5 VDC, 1800 RPM at 2.5 VDC, and variable RPM above and below
2.5 VDC. Note confirmation on the load test. Take screen shots to document the ECU programming and include with the load test reports for each engine.
2. Run the engine with adequate load to get up to normal operating temperature. Check Service Advisor and verify that the engine is functioning properly and that all parameters are within normal ranges.
3. Perform a Cylinder Cutout Test in accordance with the manufacturer’s procedures. If any cylinders test abnormally, perform a Cylinder Misfire Test and a Cylinder Electronic Compression Test. If any injectors appear to be defective replace and then repeat tests.
4. Record the results of the tests, including any corrections made, in the load test report.
F. Load Test: Perform a standard commercial shop 8 hour load test on each engine generator including, but not limited to, the following:
1. Place engine in continuous operation without stoppage for a period of not less than eight hours. Operate not less than one hour at each load point (1/2, 26 32 13-16
3/4, and full load) and 1 hour at 110 percent of rated load. If stoppage becomes necessary during this period, repeat the 8-hour run.
2. Record the following data at the start, at 15-minute intervals, and at the end of each load run: Hz, kW load, fuel consumption, exhaust temperature, intake air temperature, jacket water temperature, coolant return temperature, lube oil temperature, lube oil pressure, manifold (boost) pressure, and crankcase vacuum.
3. Tests shall indicate satisfactory operation and attainment of guarantees and specified performance.
G. Provide completed test reports to the Owner. Reports shall include but not limited to the following:
1. Complete 8-hour load test data.
2. Results of Cylinder Cutout Test and any subsequent tests performed.

4. Photos of split oil filters as described below.
5. Laboratory analysis of the clean lube oil sample and the sample pulled after the test as described below.
3.3 PREPARATION AND SHIPPING
A. Upon completion of testing perform the following steps to prepare for shipping:
1. Flush the cooling system with extended life 50/50 ethylene glycol mix, Shell Rotella ELC or approved equal. Install covers over the connections.
Note that if testing was performed with extended life ethylene glycol solution the engine does not need to be flushed.
2. Pull a sample of the lube oil. Send to a laboratory for analysis. Include the sample of clean lube oil pulled prior to the load test for reference comparison.
3. Remove oil filter, split case, inspect contents and take photo to document.
Note that if excessive or unusual metal fragments are found, contact the Owner immediately. Install new oil filter.
4. Turn the engine at cranking speed with throttle control in full off position and use a sprayer to add a mixture of 50% VCI (volatile corrosion inhibitor) oil and 50% 30-weight engine oil into the engine long enough to ensure the cylinders and exhaust ports are coated.
a. For marine engines with a jacket water aftercooler, spray the VCI-oil mixture directly into the air intake manifold and then separately spray a small amount into the turbocharger inlet.
b. For engines without a jacket water aftercooler, spray the VCI-oil mixture into the turbocharger inlet.
5. Clean the outside of the engine and inspect and ensure that the engine and generator are covered by good quality paint. Correct any deficiencies.
26 32 13-17
6. Spray a thin amount of VCI-oil mixture on the flywheel, ring gear teeth, and starter pinion. Install the covers to keep the vapors in.
7. Install a positive mechanical seal consisting of a fitting plate and gasket on exhaust opening. Then install all covers and/or tape on any other openings.
Ensure all covers are air tight and weatherproof. Use waterproof, weather resistant type tape. Do not install tape in such a manner as will damage paint when the tape is removed. Install a mechanical protective device over any protruding items, which may be vulnerable to damage during transportation.
B. After preparing the equipment for shipping, package each engine generator separately as follows:
1. Coil wiring harnesses and secure control wiring junction box and ECU mounting panel to generator.
2. Put a waterproof cover over the entire engine generator unit. Make the cover tight, but loose enough to let air circulate around the unit to prevent damage to exposed metal parts from condensation.
3. All other included components (spare parts, loose items, etc.) shall be packaged individually in waterproof wrapping. Each individual component package shall then be packed in a box or crate, and each box/crate wrapped in waterproof wrapping to prevent corrosion to the components during extended periods of outside storage.

Information: The factory settings for the engine speed control (governor) parameters have been optimized for the majority of applications to provide the best combination of stability and response characteristics.
DO NOT change these settings from the defaults unless there is a significant problem with engine speed stability or response to load changes. Changing the governor gains from the defaults can aggravate instabilities in the system or lead to unacceptable response. Any changes must be evaluated to determine if the final performance is acceptable.
