1. Structural Advantages of the Bosch 0445020093 Pump
The 0445020093 belongs to the Bosch CP3S3 family, one of the most robust high‑pressure pump platforms in the diesel industry. Its design offers several key benefits for Case and New Holland engines:
Three‑Plunger Radial Piston Design – Uses three radial plungers arranged around an eccentric cam ring, delivering exceptionally smooth, high‑volume fuel flow with minimal pressure pulsation. This reduces mechanical stress on the common rail and injectors – critical for engines that operate for long hours under variable loads.
Integrated Vane‑Type Transfer Pump – A built‑in low‑pressure vane pump draws fuel directly from the tank and supplies the high‑pressure plungers, ensuring consistent inlet pressure even when the lift pump is weak. This simplifies installation and removes a common failure point.
High‑Pressure Capability (1,800 bar) – Generates rail pressures up to 1,800 bar (26,100 psi), enabling superior fuel atomisation for complete combustion, lower soot formation, and improved fuel economy – essential for Tier 4 and Stage V emissions compliance.
Heavy‑Duty Drive Shaft & Bearings – Designed to withstand the high torsional loads and vibration of agricultural and construction engines, ensuring long service life in dusty, wet, and high‑vibration environments.
High‑Pressure Fuel Lubrication – All moving internal parts (plungers, roller shoes, eccentric cam) are lubricated solely by diesel fuel, eliminating external oil lines and simplifying installation.
Integrated Digital Flow Control Valve (ZME) – An inlet metering solenoid valve precisely regulates fuel entry based on ECU demand, providing accurate rail pressure control, improved throttle response, and lower fuel consumption.
Robust Cast Iron Housing – The pump body is manufactured from high‑strength cast iron with an anti‑corrosion coating, engineered to withstand vibration, thermal cycling, road salt, moisture, and dust encountered in agricultural and off‑road operations.
Direct Bosch CP3S3 Compatibility – Identical mounting flange (3‑bolt SAE A), drive gear interface, high‑pressure outlet ports, and electrical connector as the original Bosch 0445020093. True plug‑and‑play replacement with no modifications.
2. Compatible Case / New Holland Models (≤5)

✅ Important Fitment Note – The 0445020093 may also be listed under Case / New Holland OEM numbers such as 5802723293, 504047306, or 504087957. Always verify the Bosch number on your original pump (stamped on the nameplate) and confirm your engine code (e.g., F4AE, F4HE, N67, NEF6). Contact us with your machine model and serial number for fitment confirmation.
3. Common Failures & Professional Installation/Replacement Advice
3.1 Typical Symptoms of a Failing 0445020093 Pump
Loss of power under load – Tractor struggles to pull implements or combine loses rotor speed in heavy crop, often accompanied by black exhaust smoke.
Extended cranking time before start – Rail pressure builds slowly, especially after the machine sits overnight.
Engine surging or rough idle – Inconsistent fuel delivery at low RPM, causing hunting or misfiring.
DTC codes P0087, P0088, or P0191 – Rail pressure too low, too high, or sensor rationality fault. Use Case/New Holland Electronic Service Tool (EST) or Bosch KTS to confirm.
Metal particles in the fuel filter – A clear sign of CP3 internal wear (plunger scuffing or roller bearing failure). Even small ferrous particles indicate imminent pump failure.
External fuel leakage – Visible diesel around the pump body, particularly at the drive shaft seal or around the ZME metering valve.
Diesel contamination in engine oil – A failed drive shaft seal allows fuel to enter the crankcase, leading to rising oil level and risk of engine damage.
3.2 Professional Installation & Replacement Recommendations
Perform a complete fuel system diagnosis – Use the manufacturer’s diagnostic tool (EST or aftermarket equivalent) to read fault codes, monitor rail pressure, and measure injector return flow rates. Identify any injectors with excessive return flow.
Replace the fuel metering valve (ZME) – If the old pump has failed internally, replace the ZME solenoid valve (Bosch part number typically 0928400640 or equivalent) with a new one. A faulty ZME can cause repeat pump failure.
Replace all fuel filters – Install new Case/New Holland OEM or high‑quality primary (water separator) and secondary fuel filters before running the new pump. CP3 pumps are sensitive to contamination.
Flush the entire fuel system – Drain and clean the fuel tank. Blow out all supply and return lines with compressed air. Replace any rubber hoses that show degradation. This step is non‑negotiable – debris from a failed pump will destroy a new CP3 within minutes.
Inspect and flow‑test all injectors – High return flow from worn injectors will prevent correct rail pressure and cause repeat pump failure. Have all injectors professionally cleaned or replaced as necessary. For FPT engines, use a Bosch EPS test bench.
Replace the engine oil and filter – If diesel has contaminated the oil (rising level or diesel smell), change the oil and filter BEFORE running the new pump.
Prime the low‑pressure circuit – Use a hand vacuum pump on the fuel return line to pull bubble‑free fuel through the pump and filters. CP3 pumps are self‑priming but dry cranking will score the plungers.
Fill the pump with clean diesel – Remove the high‑pressure outlet fitting and pour clean, lubricious diesel (or Bosch assembly lubricant) into the pump housing to prevent dry start scoring.
Torque all connections to specification – High‑pressure outlet (M14×1.5 cone seal): 40–45 Nm. Low‑pressure inlet (M16×1.5): 25 Nm. High‑pressure line union nuts: 35–40 Nm. Drive shaft nut: consult the Case/New Holland workshop manual (typically 100–130 Nm). Use a calibrated torque wrench.
Reset fuel adaptations – After installation, use diagnostic software to clear learned fuel trim values and perform a “high‑pressure pump adaptation” or “fuel system learn” routine.
Perform a leak test – Idle the engine for 10 minutes, then inspect all high‑pressure and low‑pressure unions, the pump mounting area, and the drive shaft seal for any signs of fuel wetness.
Monitor rail pressure – Using live data, verify that actual rail pressure tracks within ±20 bar of specified value across all RPM ranges. Perform a field test under load.
💡 Pro Tip – Agricultural machinery often operates in dusty, wet conditions. Always drain the water separator daily. Consider installing an additional 5‑micron fuel filter and using a fuel additive with lubricity enhancer to extend pump and injector life. Keep the fuel tank topped up to minimise condensation.
