Description
Gear wheel of the injection pump for 1.4 eHDI and 1.6 eHDI engines for CITROËN and PEUGEOT vehicles.
This replacement injection-pump gear is designed for mechanics and experienced DIY enthusiasts working on Stellantis diesel engines 1.4 eHDI and 1.6 eHDI. Built to restore correct drive of the high-pressure pump, the part ensures precise fuel injection timing and reliable engine operation when installed correctly. Commonly searched by OEM numbers, this component is suitable for a range of Citroën and Peugeot models and is an economical way to repair pump drive faults without replacing the entire pump assembly.
Key Benefits
Durable construction for long-term service life, direct fit to original mounting points, and exact tooth profile to maintain factory injection timing. Ideal for repairs after wear, corrosion of the original gear, or following timing-belt or accessory-drive incidents that damage the pump drive.
Fitment And Typical Applications
- Citroën Berlingo B9
- Citroën C3 Picasso
- Citroën C4 II
- Citroën C4 Picasso
- Peugeot 308
- Peugeot Partner Tepee
Fits 1.4 eHDI and 1.6 eHDI diesel engines used across Citroën and Peugeot small- and mid-size models. Often located and ordered by product code for fast identification.
How The Part Works
The gear transmits rotational drive to the injection pump, ensuring the pump delivers fuel at the correct timing and pressure. Proper engagement of the gear teeth maintains injection timing relative to the engine’s camshaft and crankshaft, which is critical for smooth running, emissions control, and engine longevity.
How To Replace (Overview)
- Disconnect the battery before starting work.
- Remove any necessary covers, belts, or accessory components to access the injection pump drive.
- Lock timing components as required and mark alignment points before removal to preserve timing reference.
- Unfasten the gear retaining bolt and remove the old gear; inspect the shaft and key for damage.
- Fit the new gear, align timing marks precisely, and secure the retaining bolt to the manufacturer’s torque specification.
- Reassemble belts and covers, prime the fuel system, bleed any trapped air, and start the engine to check for correct operation and leaks.
Work should be performed by a qualified technician if you are not experienced with diesel injection timing procedures.
Installation Recommendations
- Always disconnect the battery before beginning disassembly.
- Replace any associated fasteners or locking components that are single-use or show wear.
- Verify and align timing marks carefully; incorrect alignment can cause poor running or engine damage.
- Prime and bleed the fuel system after installation to avoid air-related start issues.
- Use the correct torque values from the vehicle manufacturer for the gear retaining bolt; do not reuse damaged bolts.
Why This Part Commonly Fails
Failure typically stems from mechanical wear of the teeth, corrosion from contaminated fluid or moisture, impact damage during accessory or timing-belt failures, or a sheared retaining bolt/key. Symptoms of a failing gear include irregular engine running, loss of power, misfires, noise from the pump area, or injection timing faults.

Recommendation
Inspect the surrounding drive components and timing belt/chain whenever replacing the pump gear. If the vehicle shows signs of fuel system air ingress after installation, repeat priming and bleeding procedures. If uncertain about timing alignment or pump priming, have the work completed or checked by a professional workshop with experience on PSA diesel systems.
