Fuel Injection Pump Services & Overhaul
Bosch Fuel Injection Pump Overhaul – Einspritzpumpen Manufaktur NRW
Einspritzpumpen Manufaktur NRW is a highly specialized engineering company dedicated to the overhaul, repair, restoration and calibration of mechanical Bosch fuel injection pumps.
We rebuild mechanical Bosch fuel injection pumps for passenger vehicles, commercial vehicles, industrial engines, marine propulsion systems and heavy-duty diesel engines with the highest level of precision and engineering expertise.
By combining traditional diesel engineering, modern precision measurement technology and extensive engine knowledge, we restore Bosch fuel injection pumps to original factory specifications or calibrate them to individually optimized performance characteristics.
Professional Overhaul of Mechanical Bosch Fuel Injection Pumps
A professional Bosch fuel injection pump overhaul involves far more than simply replacing seals or worn components.
Every fuel injection pump is completely dismantled, thoroughly cleaned, precisely measured and technically evaluated. Only components that remain within strict engineering tolerances are reused.
During every overhaul we ensure:
- Precise fuel delivery calibration
- Correct injection timing
- Smooth governor operation
- Accurate clearances of all moving components
- Long-term sealing integrity
- Reliable long-term performance
The result is a durable, reliable Bosch fuel injection pump delivering precise and repeatable fuel injection characteristics.

Our Fuel Injection Pump Rebuilding Process
1. Initial Inspection & Technical Diagnosis
Every fuel injection pump undergoes a comprehensive technical inspection including:
- Visual inspection
- Leakage testing
- Injection timing analysis
- Governor performance evaluation
- Functional assessment
2. Complete Disassembly & Cleaning
The fuel injection pump is completely dismantled into its individual components.
All parts are professionally cleaned using multi-stage industrial cleaning processes before detailed inspection.
3. Precision Measurement & Component Evaluation
Critical components are measured using precision measuring equipment, including:
- Plunger and barrel assemblies
- Camshaft
- Cam followers
- Bearings
- Shafts
- Delivery plungers
- Governor assemblies
- Control sleeves
- Control levers
- Springs
Every component is evaluated according to Bosch engineering specifications.
4. Replacement of Wear Components
Where necessary, worn parts are replaced, including:
- Plunger and barrel assemblies
- Bearings
- Bushings
- Needle bearings
- Shaft seals
- O-rings
- Gaskets
- Delivery valves
- Governor components
Whenever genuine Bosch spare parts are no longer available, we manufacture replacement components through Reverse Engineering and precision European manufacturing.
5. Precision Assembly
Every Bosch fuel injection pump is reassembled according to original Bosch specifications.
This includes:
- Precise installation of all pump elements
- Mechanical basic adjustment
- Governor synchronization
- Functional verification
Bosch EPS Test Bench Calibration
Every rebuilt Bosch fuel injection pump is calibrated on our Bosch EPS fuel injection pump test benches.
Calibration includes:
- Individual fuel delivery adjustment for each cylinder
- Fuel delivery balance verification
- Idle adjustment
- Full-load calibration
- Governor calibration
- Shut-off function testing
- Leakage testing
Only fuel injection pumps meeting all Bosch specification values leave our workshop.
