Valve Clearance - Westinghouse iGen4500cv Manual De Instrucciones

3. Place the loose end of the hose outside the generator
into an approved gasoline container to catch the drained
fuel.
4. Loosen the float bowl drain screw and allow the fuel to
drain. Tighten the float bowl drain screw.
5. Route the drain hose between the air cleaner housing and
the engine service cover. Install the engine service cover.
DRAINING THE FUEL TANK
If storing the generator for longer than six months, drain
the fuel tank to prevent fuel separation, deterioration, and
deposits in the fuel system.
1. Unscrew the fuel tank cap. Remove the fuel screen filter
by slightly compressing it while removing it from the
tank.
2. Using a commercially available gasoline hand pump
(not included), siphon the gasoline from the fuel tank
into an approved gasoline container. DO NOT use an
electric pump.
3. Reinstall the fuel screen filter and the fuel tank cap.
4. Start the generator and allow it to run until the generator
engine stops.
5. Remove the spark plug.
6. Put a teaspoon of engine oil into the cylinder and pull the
recoil handle until resistance is felt. At this position the
piston is coming up on its compression stroke and both
valves are closed. Storing the engine in this position will
help prevent internal corrosion. Return the recoil handle
gently.
7. Reinstall the spark plug. Leave the spark plug boot
disconnected to prevent accidental starting.
8. Install the engine service cover.
MAINTENANCE

VALVE CLEARANCE

Checking and adjusting valve clearance must be done
when the engine is cold.
1. Remove the rocker arm cover and carefully remove the
gasket. If the gasket is torn or damaged, it must be replaced.
2. Remove the spark plug so the engine can be rotated
more easily.
3. Rotate the engine to top dead center (TDC) by pulling the
recoil handle slowly. Looking through the spark plug hole,
the piston should be at the top (both valves are closed).
4. Both the rocker arms should be loose at TDC on the
compression stroke. If they are not, rotate the engine 360°.
5. Insert a feeler gauge between the rocker arm and the
valve stem to measure valve clearance.

6. If an adjustment is necessary, hold the rocker arm pivot
and loosen the pivot adjusting nut.
7. Turn the rocker arm pivot to obtain the specified
clearance. Hold the rocker arm pivot and re-tighten the
pivot adjusting nut to the specified torque.
Torque: 106 inch-pound (12 N•m)
8. Perform this procedure for the other valve.
9. Install the gasket, rocker arm cover, and spark plug.
