20903104 — Injector Sleeve 20903104 For Volvo Engine Tad560Ve Tad734Ge D7E290 Excavator Ec140Dl Ec220D Ec250D Ec350D

This is an injector sleeve, also known as an injector cup or liner, which provides a sealed seat for the fuel injector within the cylinder head. Manufactured from high-grade materials, it ensures a leak-free seal and proper injector alignment, unlike a corroded or damaged sleeve that can lead to fuel or coolant leaks. Operators may observe coolant in the fuel system, white smoke from the exhaust, or a loss of engine power if the injector sleeve fails.

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

A primary indicator of a failed injector sleeve is the presence of coolant in the fuel system or fuel in the coolant system, often accompanied by white exhaust smoke. If left unaddressed, this cross-contamination can lead to severe internal engine damage, including bearing failure and cylinder wall scoring. Continued operation risks significant and costly engine repairs.

Installation Tip

Ensure the injector bore in the cylinder head is meticulously cleaned and inspected for any damage before attempting to install the new sleeve. Use the correct installation tool to seat the sleeve properly without distortion.

Service Note

When replacing injector sleeves, it is highly recommended to also replace the fuel injectors themselves, as they are often removed together and may have similar wear.
