0445120376 Original BO-SCH Common Rail Injector For Doosan DL06P DX140
0445120376 Original Common Rail Injector For Doosan DL06
The 0445120376 common rail fuel injector, also written as 0 445 120 376, is used in selected Doosan DL06 Tier 4 diesel-engine applications. BO-SCH official diesel cross-reference catalogue directly maps Doosan 400903-00104 to BO-SCH 0 445 120 376, providing a strong OE-number identification point for this injector.
BO-SCH current DCI injector documentation classifies 0445120376 as CRIN3-18. This current BO-SCH classification should take priority over older or third-party catalogues that describe the injector as CRIN2-16-BL.

Repair Nozzle Reference
The strongest repair component relationship currently available is:
- Nozzle: DLLA144P2446
- Nozzle Number: 0433172446 / 0 433 172 446
Multiple independent diesel nozzle catalogues associate this nozzle directly with 0445120376.
A control-valve number is currently not published as a verified specification because available catalogues conflict on the exact valve application.
DL06 Tier 4 Fuel System
BO-SCH / Doosan application information connects 0445120376 to the same DL06 Tier 4 fuel-system architecture as:
- Fuel Injector: 0445120376 (Injector OE: 400903-00104)
- High Pressure Pump: 0445020152 (Pump OE: 400912-00030A)
- Fuel Rail: 0445226107 (Rail OE: 150120-00014)
This makes the product useful not only as an individual injector page but also as part of a complete DL06 Tier 4 fuel-system database.
Typical Equipment Applications
Secondary specialist application data identifies the 400903-00104 / 0445120376 injector with Doosan DX140LC-5, DX180LC-5, DX225LC-5, DX225LL-5 and DX255LC-5 excavators, together with D100S-7 through D160S-7 forklifts.
DX170-5 / DX170W-5 also appears in replacement-market application data, but should be treated as a secondary search node rather than the primary equipment fitment.
Order Confirmation
Recommended matching chain: 0445120376 / 400903-00104 / DL06 Tier 4 or DL06P / Machine Model / Serial Number.
Because DL06 Tier 4 uses more than one injector configuration, the engine family alone is not enough for final identification.
