3.3 Lubrication System

3.3.1

Oil Specifications

Use oil that meets the American Petroleum Institute

(API) classification of SG or SH. Using unsuitable oil or

neglecting an oil change may result in engine damage

that is not covered by the engine warranty. Figure 3-1

shows the recommended Society of Automotive

Engineers (SAE) viscosity designation for given

operating temperature ranges.

Do not mix different oil brands. Incompatibility could

cause a breakdown of lubricating ingredients and

reduce engine protection.

3.3.2

Oil Check

Check the oil level in the crankcase daily or before each

startup to ensure that the level is in the safe range. Do

not check the oil level while operating the unit. Stop the

generator set and keep the generator set level to get an

accurate reading. To check the oil level, remove the

dipstick and wipe the end clean. Reinsert the dipstick

and remove it. Maintain the oil level between the Full

and Add marks on the dipstick, as shown in Figure 3-2.

See Section 1, Service Views, for the dipstick location.

Section 3 Scheduled Maintenance

1. Full mark

2. Add mark

Figure 3-2 Oil Level Check

Note: Do not operate the set if the oil level is below the

Add mark on the dipstick or above the Full mark

on the dipstick. Too high an oil level causes high

oil consumption and engine carbonizing. Too low

a level damages the engine.

3.3.3

Oil Additions

Adding some oil between oil changes is normal. The

amount varies with the generator set usage. Open the

oil fill cap and pour in a small amount of oil using a funnel

or other suitable pouring device. See Section 1, Service

Views, for the oil check and oil fill locations.

3.3.4

Oil Change

Change the oil according to the service schedule or

before generator set storage. Change the oil more

frequently if the generator set operates under dirty,

dusty conditions. Change the oil while the engine is still

warm.

See Figure 3-3 for the oil capacity.

locations.
