FUEL INJECTOR REPLACEMENT (Contd)
Diesel fuel is flammable. Do not perform fuel system procedures
near open flame. Injury to personnel may result.
All fuel injectors are replaced in the same way. This procedure is
for the replacement of one fuel injector.
Loosen three jamnuts (6) and back out three adjusting screws (8) on rocker arm assembly (5).
Anchor is only installed on No.1 cylinder rocker arm assembly.
Support rocker arm assembly during removal to prevent damage.

valve pushrods (2) from cylinder head (7).
Remove injector holddown screw (9) from cylinder head (7) and fuel injector holddown bracket (14).
Do not pry on injector holddown bracket. Use notch on opposite

spring. Failure to do so may result in damage to fuel injector.
