0445120182

Check that the OE stamping on the F00RJ02703 magnet assembly matches the Dongfeng Cummins DCI11 application. The 10-digit SKU 0445120182 should match the build plate on the original injector, and the DLLA150P2142 nozzle stamping (0433172142) should be visible. The IMA/Trim code is unique - cross-reference via BOSCH ESITronic or your Dongfeng Cummins dealer for the exact match. Do NOT substitute 0445120183 without verifying the IMA code - the F00RJ02472 valve group is shared but calibration differs.

F00RJ02472 is the primary control valve for 0445120182 and 7 sister SKUs in the F00RJ02472 group: 0445120182, 0445120183, 0445120242, 0445120289, 0445120329, 0445120383, 0445120347. The CRIN2 magnet assembly is F00RJ02703 (Bosch dieselcatalog list of 0445120182 replacing parts). Same valve group but different IMA/Trim code per SKU - NOT interchangeable without ECU re-coding.

Both share the F00RJ02472 control valve, but each carries a unique IMA (Injection Quantity Adjustment) and Trim code. Installing 0445120183 in a DCI11 application that specifies 0445120182 will trigger P0201-P0206 fault codes and may cause over-fueling (black smoke, piston melting risk) or hard starting. Always verify the OE number and the IMA/Trim code stamped on the F00RJ02703 magnet assembly.

Typical failures include: (1) F00RJ02472 control valve wear causing over-fueling (black smoke under load, piston melting risk) after 200,000-300,000 km; (2) DLLA150P2142 nozzle coking from poor fuel quality (P0300 random misfire, white smoke on startup from leaking needle seat); (3) F00RJ02703 CRIN2 magnet assembly coil failure (P0201 fault); (4) high-pressure line sealing washer failure; (5) copper washer compression set. For heavy trucks operating at high load, recommend replacement at 250,000 km or first symptom.

Disconnect the electrical connector from the F00RJ02703 magnet assembly, set multimeter to ohms (200 ohm range), measure across the two solenoid terminals. Normal resistance: 0.5-2.0 ohm at room temperature (cold engine, off for 30 min). Open circuit (>10 M ohm) = replace injector. Short circuit (<0.1 ohm) = replace. Always test cold for accurate reading. After replacement, the IMA/Trim code must be written to the ECU via BOSCH KTS 590 or ESITronic.

Peak rail pressure is 1800 bar in the DCI11 common rail system. Low-pressure feed must be 4-6 bar. If the rail pressure drops below 1500 bar under load, suspect a worn F00RJ02472 control valve or clogged DLLA150P2142 nozzle. For DCI11-340/380 engines, also check the fuel line diameter - some documented cases of 200 bar pressure drop due to undersized 5mm lines (replace with 8mm minimum).

Mechanical install is moderate (30-35 N·m on CRIN2 hold-down clamp, 45-55 N·m on high-pressure line, 15mm/17mm wrenches for the 2-wrench procedure), but ECU IMA/Trim coding requires BOSCH KTS 590 or ESITronic scanner. Without coding, expect rough running and emissions failures. Most workshops handle this in 3-4 hours total. Critical: insert the injector vertically - any tilt will damage the F00RJ02472 valve.

12 months from invoice date, covers manufacturing defects, F00RJ02703 magnet assembly failure, and DLLA150P2142 nozzle defects. Warranty does not cover damage from contaminated fuel (especially water, common in construction site refueling), incorrect installation (tilted insertion, over-torque), or failure to write IMA/Trim code to ECU. Keep installation record and BOSCH ESITronic coding log for any warranty claim.

0445120182 is rated for Euro 4 (DCI11-340/380 Euro 4 configuration). It can also be used in Euro 3 DCI11 applications (typically the DCI11-300/320 variants) because the F00RJ02472 control valve and DLLA150P2142 nozzle are shared. For Euro 5 DCI11 applications, the system adds SCR post-treatment and the IMA calibration may differ - confirm with your dealer for the SCR-equipped variant. The 0445120242 SKU is the typical Euro 5 upgrade option.
