4.2 Lubrication System

See the service schedules in Section 4.1 for oil change and oil filter replacement intervals. See the service views in Section 1.7 for the oil drain, oil dipstick, oil fill, and oil filter locations.

4.2.1Low Oil Pressure Shutdown

The low oil pressure (LOP) shutdown feature protects the engine against internal damage if the oil pressure drops below a minimum pressure because of oil pump failure or other malfunction.

Note: The LOP shutdown feature does not protect against damage caused by operating when the oil level is low; it is not a low oil level shutdown. Check the oil level regularly, and add oil as needed.

4.2.2Oil Check

The generator set is shipped with oil. Before operating the generator set, check the engine oil in the crankcase. See Figure 4-1.

Maintain the oil level at or near, not over, the full mark on the dipstick. Add 5W-30 synthetic oil when the oil level is low.

Check the oil level before each use. For extended operation, check the oil level every 8 hours. Do not check the oil level when the generator set is running. Shut down the generator set and wait several minutes before checking the oil.

4.2.3Engine Oil Recommendation

Use 5W-30 API (American Petroleum Institute) Service Class SG, SH, or SJ synthetic oil. Synthetic oil oxidizes and thickens less than other oils and leaves the engine intake valves and pistons cleaner.

4.2.4Oil Change Procedure

Note: Dispose of all waste materials (engine oil, fuel, filter, etc.) in an environmentally safe manner.

Drain the oil while it is still warm.

1.Drain the oil.

a.Press the OFF button on the generator set controller.

b.Disconnect the AC power to the generator set.

c.Disconnect the generator set engine starting battery, negative (–) lead first.

d.Open the housing service door and remove roof panel.

e.Clean the area around the dipstick and oil fill cap.

f.Remove the screw in plug on drain fitting in skid rail.

i.Close the oil drain valve. Replace the cap in skid rail.

j.Replace the dipstick.

2.Replace the oil filter.

a.Clean the area around the oil filter. Remove the oil filter by rotating it counterclockwise with an oil filter wrench.
