Fuel Injector Replacement

FUEL INJECTOR REPLACEMENT

REMOVAL PROCEDURE

IMPORTANT: The engine oil may be contaminated with fuel if the fuel injectors are leaking.




1. Remove the fuel meter body.
2. Remove the injector retainer lock nuts (4) and retainer (2).
3. While pulling the fuel injector downward, push with a small tip punch down between the injector terminals until the injector is removed.

NOTE: Use care in removing the fuel injectors to prevent damage to the electrical connector terminals.

The fuel injector is serviced as a complete assembly only.

Also since the injectors are electrical components, these injectors should not be immersed in any type of liquid solvent or cleaner as damage may occur. Fuel injector cleaning is not recommended.

INSTALLATION PROCEDURE

IMPORTANT: When ordering new fuel injectors, be sure to order the correct injector for the application being serviced.




1. Lubricate the NEW injector O-ring seals with clean engine oil.
2. Install the fuel injector (3) into the fuel meter body injector socket.

NOTE: Refer to Fastener Notice in Service Precautions.

3. Install the retainer (4) and the injector retainer lock nuts (2).

Tighten the nuts to 3 N.m (27 lb in).

4. Install the fuel meter body.
