FAQ

Q: Will this injector fit my Daewoo Doosan DX225 excavator?
A: It is compatible with many Daewoo Doosan models using the Bosch common rail system, including the DX225 with the DL06 engine. However, we recommend comparing your old injector’s part number (0445120040) and physical size to ensure correct fitment, as engine variants exist.

Q: Is this injector new or remanufactured?
A: This is a brand new, non-remanufactured injector. It has never been used and comes with the original packaging. New injectors provide superior reliability compared to rebuilt units.

Q: What is the recommended installation procedure?
A: Installation should be performed by a qualified diesel technician. Key steps include: removing the old injector, cleaning the mounting bore, lubricating the O-ring, torquing to manufacturer specifications, and bleeding the fuel system. Always replace copper washers/seals and use a new high-pressure fuel line if damaged.
