0445020127 Original CP3 Fuel Pump For Doosan DX300LC / DX340LC Excavator

The 0445020127 high-pressure common rail fuel pump, also written as 0 445 020 127, is used in selected Doosan DL08 Tier 3 diesel engine applications. In the field this pump is most often requested for DL08-powered excavators, including DX300LC, DX300LCA, DX340LC and DX360LCA.

Bo-sch's official diesel cross-reference catalogue directly maps Doosan 65.10501-7006 to Bo-sch 0 445 020 127, while Bo-sch / Doosan application documentation identifies the unit as a radial piston pump for DL08 Tier 3. The pump supplies high-pressure diesel fuel to the common rail system and uses an electronically controlled metering unit to regulate incoming fuel volume.

Excavator Application Notes
