Adding Oil

It is normal to add some oil between oil changes. The amount will vary with the usage. Open fill cap and pour a small amount of oil using a funnel or other suitable pouring device. See Figure 3-4. Wait a few minutes and check level. If necessary, add more oil and then check again. Each time be sure to add small quantities and check to prevent overfilling.

Figure 3-5. Oil Drain Cap

1.Place oil drain hose in a proper container. Remove oil drain cap. If a drain pump is used, remove oil drain cap and connect oil drain hose to drain pump.

2.Allow ample time for all oil to drain into container. If drain pump is used, activate pump until oil is removed.

3.Loosen oil filter by turning in a counterclockwise direction. Oil filter is 2 1/2 in. (64 mm) dia. with 14 flutes. Use oil filter wrench, if necessary. See Figure 3-6. Use rags to handle hot oil filter and clean up spilled oil. Remove filter from oil filter adapter on engine and discard oil filter in a proper container.

4.Clean contact surface of oil filter adapter.

5.Lightly lubricate the gasket surface of new oil filter with fresh engine oil. Thread oil filter onto oil filter adapter until gasket makes contact; then hand-tighten oil filter an additional 3/4 turn.

NOTE

If an automatic oil drain/oil fill pump is used, omit Step 6. Fill with proper amount and type of oil, see Step 6. When complete, replace cap and disconnect pump.

6.Replace oil drain cap. Remove oil fill cap. Add oil using a funnel or other suitable pouring device. See Specifications— Engine for oil capacity and Lubrication System— Specifications for proper service class and SAE viscosity of oil. Replace oil fill cap.

7.Start generator set and check for leaks at oil drain cap and oil filter.

8.Stop generator set. Wait a few minutes for oil to return to oil pan. Remove dipstick and wipe clean, reinsert as far as possible and remove to check oil level. Add oil, as necessary, to bring level up to MAX mark.
