229-1490 6 Pcs Injector Sleeve — Cat

These are injector sleeves that provide a seal and support for the fuel injectors within the engine block. Manufactured to meet rigorous OEM material specifications, they offer superior durability and sealing compared to worn or corroded sleeves that can lead to fuel leaks. Operators may experience rough idling, reduced engine power, or fuel in the engine oil when these sleeves fail.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Early signs of injector sleeve failure include a noticeable drop in engine performance or the presence of fuel in the engine oil. If ignored, the engine may begin to misfire, and fuel dilution of the oil can accelerate internal engine wear. The ultimate consequence is potential engine damage due to lubrication failure and improper combustion.

Installation Tip

Ensure the injector bore in the cylinder head is meticulously cleaned and inspected for any damage before installing new sleeves. Press the new sleeves in carefully and squarely to prevent cocking, which can compromise the seal.

Service Note

When replacing injector sleeves, it is highly recommended to inspect and service the fuel injectors themselves.
