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.

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: ENGINE UPGRADE REMANUFACTURED DESCRIPTION *REF NEW P/N TO NEW P/N P/N 3114 0R2842 0R2743 CYL.
