FAQ

Q1: How do I know if this copper sleeve (2274236/2634920) is the correct one for my Caterpillar C18 engine?
A: The primary identification is the part number. Locate the existing sleeve on your engine or check your engine’s parts manual for the OEM number 2274236 or 2634920. While this sleeve is designed for C18 and C13 models, we recommend cross-referencing your engine’s serial number prefix (e.g., C18 serial number) to confirm fitment, as minor revisions may exist.

Q2: What are the critical installation steps for this fuel injector copper sleeve?
A: Correct installation is vital. The cylinder head bore must be perfectly clean and free of carbon deposits. The new sleeve must be driven in squarely to the correct depth to ensure proper injector protrusion. It is highly recommended to use a specialized sleeve installation tool and a depth micrometer to verify the injector tip height after installation. Failure to install correctly can lead to injector failure or combustion leaks.

Q3: Can a damaged copper sleeve cause other engine problems if not replaced?
A: Absolutely. A worn or cracked copper sleeve can allow high-pressure fuel to leak past the injector. This can lead to fuel dilution of the engine oil, reducing lubrication and potentially causing bearing or cylinder liner damage. It can also cause a loss of compression, white smoke from the exhaust, and a noticeable drop in engine power. Replacing the sleeve during an injector overhaul is a standard best practice to prevent these issues.
