Description
Toothed crankshaft gear for Citroën and Peugeot vehicles with 1.4 HDi and 1.6 HDi engines. Timing drive pinion.
High-quality replacement crankshaft sprocket designed for PSA Group diesel engines (1.4 HDi and 1.6 HDi). This toothed pulley transmits the crankshaft rotation to the timing system and is a critical component for maintaining correct valve timing and engine operation. Ideal for professional workshops and experienced DIY mechanics looking for a reliable component with clear OEM cross-references.
Features And Benefits
- Direct Fit For Common PSA Engines: Engineered to match original geometry and tooth profile for smooth engagement with the timing belt.
- Reliable Timing Transmission: Ensures accurate transfer of crankshaft motion to camshafts and auxiliary timing components.
- Durability For Workshop Use: Built to withstand the loads and environmental conditions typical of HDi diesel engines.
- Easy To Find By Part Number: Frequently searched under part numbers 9810698080 and 0805E5.
Compatibility Examples
Commonly fitted to Citroën and Peugeot models equipped with 1.4 HDi and 1.6 HDi engines. Typical applications include small and compact models such as Citroën C3, Citroën C4, Citroën Berlingo and Peugeot 207, Peugeot 307, Peugeot Partner, among others. Always match the part number on the unit to ensure correct fitment.
Replacement Procedure (Summary For Professionals And DIY)
- Prepare The Vehicle: Park on a level surface, engage the handbrake and support the vehicle securely on stands if required. Remove any engine covers and ancillary components that block access to the timing area.
- Set Engine To TDC: Rotate the crankshaft to Top Dead Center (TDC) on cylinder 1 and lock the crankshaft and camshafts according to the service manual to preserve timing alignment.
- Release Timing Belt Tension: Loosen the timing belt tensioner and remove the timing belt to relieve load from the crankshaft sprocket.
- Remove Old Sprocket: Unfasten the crankshaft sprocket retaining bolt (observe manufacturer torque/locking procedures) and remove the pulley/sprocket from the crankshaft shaft keyway.
- Install New Sprocket: Fit the new sprocket onto the crankshaft keyway, ensuring correct orientation and full seating. Tighten the retaining bolt to the Manufacturer’S Specified Torque.
- Reassemble And Verify Timing: Refit the timing belt, set correct tension, rotate the engine by hand for two full revolutions and recheck timing marks and clearances before final assembly.
Service Interval And When To Replace
This sprocket is a wear item that is typically inspected or replaced during timing belt service. Many service schedules coincide with timing belt replacement intervals; depending on vehicle use and manufacturer recommendations, this can be in the region of 100,000–120,000 km or every 5–7 years. Replace the sprocket immediately if teeth show wear, deformation, or damage, or if there is play on the crankshaft keyway.
Why This Part Commonly Fails
- Tooth Wear And Rounding: Prolonged use and belt tension can wear the tooth profile, causing timing belt slip or accelerated belt wear.
- Corrosion And Contamination: Oil leakage or road contaminants accelerate deterioration and can cause seizure or uneven wear.
- Keyway Damage Or Sheared Key: Improper installation, high loads, or fatigue can damage the crankshaft key or cause the key to shear, resulting in timing misalignment.
- Tensioner Or Belt Failure: A failed tensioner or degraded belt increases loads on the sprocket and shortens its life.
Installation Recommendations
- Always Replace Associated Components: When replacing the crankshaft sprocket, it is recommended to replace the timing belt, tensioner, and idler pulleys at the same time to avoid premature failure of the new sprocket.
- Use Proper Tools And Procedures: Lock the engine timing positions, use the correct torque settings and follow the manufacturer’S removal/installation steps.
- Inspect For Oil Leaks: Address any front main seal or camshaft seal leaks before reassembly to prevent contamination of the new sprocket and timing belt.
- Final Check: After reassembly, rotate the engine by hand to ensure smooth operation and correct timing mark alignment before starting the engine.
