227-2911 6 Pcs Injector Sleeve — Cat C15

This set of six injector sleeves serves as a critical seal between the fuel injector and the engine cylinder head, preventing combustion gases from entering the fuel system. Manufactured to precise tolerances, these sleeves ensure proper injector seating and fuel atomization, unlike worn sleeves which can cause leaks and poor performance. Operators may notice rough idling, reduced engine power, or black smoke from the exhaust when these sleeves begin to 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 indicators of failing injector sleeves include a noticeable drop in engine performance and increased fuel consumption. If ignored, combustion gases can leak, leading to injector damage and potential contamination of the engine oil. Continued operation risks significant fuel system and engine damage.

Installation Tip

Ensure the injector bore in the cylinder head is meticulously cleaned and free of any carbon buildup or corrosion before installing the new sleeves. Avoid using excessive force when seating the sleeves, as improper installation can cause them to crack or seal poorly.

Service Note

Inspect fuel injectors for wear or damage, and check the fuel lines and seals for any signs of leaks.
