ISSUE
When servicing fuel injectors on the 6.0L Diesel Engine, it is essential that the injectors are reinstalled properly. It has been noted that some Ford
Authorized Dealers are installing and/or reinstalling injectors incorrectly resulting in injector failure.
ACTION
Refer to the following Service Tips, along with the Injector Service Procedure found in the Ford Workshop Manual to assist with performing injector
replacement correctly.
INJECTOR INSTALLATION SERVICE TIPS
^
Remove/Install injectors with hand tools only. Use of power tools (Air and/or Electric) will damage to the injector and injector 0-ring(s).
^
Upon removal of an injector, inspect all 0-ring(s) to ensure that they are all present and not damaged (i.e. Cut, Gouged, Torn, etc.). If there is a defect
on the injector sleeve, replace the sleeve per Workshop Manual Section 303-04D.
NOTE
IF THE INJECTOR IS GOING TO BE REUSED ALWAYS REPLACE THE 0-RINGS AND COPPER GASKET (ONE (1) COPPER
COMBUSTION SEAL, TWO (2) FUEL 0-RINGS).
^
With the injector removed, inspect the injector sleeve for any debris. Remove all debris before the new injector is installed. Utilize special tools
303-D111 and 303-D112 to assist this process.
^
Utilize a T-40 Torx bit with a minimum shaft length of 2" to remove and install the injectors. If the Torx bit is too short, it will contact the injector
body and may result in damage to the injector, or inadequate torque during installation.
^
Prior to installation of the injector, inspect the combustion seal and all 0-rings to ensure that they are present, not damaged, or rolled in the injector
groove.
^
Prior to installing the injector, lubricate the two (2) fuel 0-rings with clean diesel engine oil.
