WARNING
If the engine has been running, it may be hot enough to ignite any fuel that leaks
out during fuel system maintenance. Make sure that the engine and its parts are
cool to the touch before disassembling any part of the fuel system. Failure to
observe this warning can result in a fire and serious personal injury.
1.
Remove the fuel tank assembly from the pump skid. Refer to REPLACE and Diesel Engine.
2.
Remove the fuel return hose assembly and clamp.
3.
Disconnect the fuel injection pipe from the fuel injection valve.
4.
Remove the two nuts and retaining plate from the top of the valve.
CAUTION
When removing the fuel injection valve, be careful not to damage the nozzle spacer
and nozzle spacer sleeve. When setting the valve down, wrap it in a cloth to
protect the nozzle tip. Do not place the nozzle tip directly on the ground. Failure
to observe this caution may result in damage to the nozzle tip or spacer sleeve.
5. Carefully pull the valve out of the cylinder head. If it does not come out easily, temporarily
reconnect the fuel injection pipe and gently pry up on the connection nut to loosen the valve.
6. Remove the nozzle spacer sleeve.
NOTE
The spacer sleeve may stick in the cylinder head when you remove the fuel
injection valve. Be sure to remove the spacer sleeve before installing the new
valve.
