CRANKCASE BREATHER: The Onan engine is equipped with a crankcase breather that prevents pressure from building up inside the crankcase, pre- vents moisture contamination from moisture, gasoline vapors, or combustion vapors. If the breather valve becomes sticky, it can cause oil leaks, oil consump- tion, rough idle, reduced power, and sludge and var- nish buildup in the engine.

The breather cannot be serviced. However, it should be periodically inspected and replaced if cracked or broken, or if the crankcase becomes pressurized. Evidence of high pressure includes oil leaks at the seals or excessive oil in the air cleaner housing.

CLEAN ENGINE: Remove dirt and debris with a cloth or brush. Do not clean with a forceful spray of water. Water might contaminate the fuel system.

CAUTION

Periodically clean the muffler area to remove com- bustible debris.

CLEAN AIR INTAKE/COOLING AREAS: To ensure proper cooling, make sure the grass screen, cooling fins, and other external engine surfaces are always kept clean. This will prevent overspeeding, overheat- ing, and engine damage due to dirt or debris buildup. Every 50 operating hours or as often as necessary, remove the blower housing and other cooling shrouds. Clean the cooling fins and external surfaces as neces- sary. Make sure to replace all the cooling shrouds. Running the engine without the cooling shrouds will cause damage to the engine from overheating.

CLEAN OR REPLACE SPARK PLUGS: Clean or replace the spark plugs after every 500 hours of oper- ation as follows.

1.Before removing the plugs, clean the base area to keep dirt from falling into the engine through the plug hole.

2.Remove and inspect the plugs. Plugs showing signs of fouling or electrode wear should be replaced. Do not blast the spark plugs clean with an abrasive cleaning device. Clean the plugs by scraping or by using a wire brush. Wash the plugs with a commercial solvent.

3.After cleaning or when installing a new spark plug, set the terminal gap with a feeler gauge. See Figure D.3.

Gap Specifications: 0.025 inch (.64 mm)

CLEAN SPARK ARRESTER SCREEN: If the muffler has the optional spark arrester, remove it every 50 hours or once a year, whichever comes first, and inspect it. Clean the arrester. Replace it if you find any damage.

REMOVE COMBUSTION DEPOSITS: Combustion deposits (carbon) can form on the cylinder, cylinder head, top of the piston, and around the valves over time, depending on engine loading conditions, type of fuel used, and other factors that affect engine perfor- mance. Consult your local Onan engine distributor for recommended cleaning intervals and procedures.
