Problem

The fuel injector sleeves in the cylinder head of certain IT14B Integrated
Toolcarriers; 213B, 214B, and 224B Excavators; 446 Backhoe Loaders; and 3114
and 3116 Industrial and Generator Set Engines are subject to pitting and
erosion due to fuel cavitation between the injector and the sleeve. The
sleeves may pit or crack through, allowing fuel to contaminate the coolant.
Coolant contaminated with fuel may also damage the radiator and coolant
hoses.

NOTE: Positive identification of the unit injectors can be made by part
number only. Part numbers are found on either the hold down
clamp or the spring retainer. New versions of injectors have
improved edge filters and o-ring tip seals for improved
combustion gas sealing.
The new versions can be distinguished from the former version by
the smooth sided edge filter on the pump body and the o-ring seal
on the tip. Former versions have a ribbed edge filter and no
provisions for an o-ring tip seal. All injectors in an engine
must be of the same version.
All injectors will be used in the remanufacturing process.
** You may decide to replace the injector sleeves in the cylinder head
instead of exchanging the head. If you do so, the following parts, tools
and instructions are needed:
6 - 7W5749 Sleeve (order 4 for a 3114 Engine)
1 - 4C4462 Tool Group (for removal and installation of injector
sleeves)
1 - SEHS9120 "Removal And Installation Of Unit Injector Sleeve"
If a Remanufactured Cylinder Head is desired, refer to the following list:

*** Check the parts book for your engine to determine the specific coolant
hose part numbers for your application. All hoses that have been in contact
with fuel contaminated coolant should be replaced.

Action Required

Follow the procedures in the Service Manual.
Remove and install the cylinder head and injectors. Synchronize the
injectors, adjust the fuel setting, fuel timing, and valve lash.
