6.7 CLEANING THE PUMP
Procedure
Result
WATER PUMP
Perform the procedure below to clean the pump.
1.
Wash the engine and pump. Wash the engine by hand, and be careful to prevent
water from entering the air cleaneror muffler opening. Keep water away from
controls and all other places that are difficult to dry, as water promotes rust.
NOTICE: Using a garden hose or pressure washing equipment can force water into the air
cleaner or muffler opening. Water in the air cleaner will soak the air filter, and water that
passes through the air filter or muffler can enter the cylinder, causing damage. Water
contacting a hot engine can cause damage. If the engine has been running, allow it to cool
for at least half an hour before washing.
2.
Wipe dry all accessible surfaces.
3.
Fill the pump chamber with clean, fresh water, start the engine outdoors, and let it
run until it reaches normal operating temperature to evaporate any external water.
NOTICE: Dry operation will damage the pump seal. Be sure the pump chamber is filled
with water before starting the engine.
4.
Stop the engine, and allow it to cool.
5.
Remove the pump drain plug (a), and flush the pump with clean, fresh water. Allow
the water to drain from the pump chamber, and then reinstall the drain plug (a).
6.
After the pump is clean and dry, touch up any damaged paint, and coat areas that
may rust with a light film of oil. Lubricate controls with a silicone spray lubricant.
WARNING:
The impeller may develop sharp edges. Use care when cleaning around the impeller to
avoid getting cut.
The pump has been cleaned.
