Description
Toothed camshaft sprocket for Citroën and Peugeot vehicles with 1.6 HDi and 1.6 e-HDi engines.
Product Overview
This camshaft sprocket (cam gear) is an OEM-design replacement part intended for 1.6 HDi / 1.6 e-HDi diesel engines fitted to Citroën and Peugeot models. It is an essential component of the timing drive, transferring rotation from the timing belt to the camshaft to ensure precise valve timing. The part is commonly searched by original part numbers, making it easy for professional technicians and DIY enthusiasts to find and order.
Key Benefits
- Direct fit for specified 1.6 HDi / 1.6 e-HDi engines — simplifies installation and reduces downtime.
- Exact tooth profile for reliable timing belt engagement and minimal slack or noise.
- Suitable For Workshops And Experienced DIY Mechanics — ideal when replacing timing components or servicing the timing belt system.
How It Works And When To Replace
The camshaft sprocket mounts on the camshaft and engages the timing belt, converting the belt’s linear motion into camshaft rotation. Proper function is critical for valve timing, engine performance, fuel economy and emissions. Replace the sprocket when worn teeth, corrosion, damaged mounting surfaces or excessive play are observed. It is good practice to inspect or replace the sprocket whenever the timing belt, tensioner or idlers are serviced.
Installation Guidance
Replacement Requires Accurate Timing Alignment. General steps: disconnect the battery; secure the engine at the correct timing position (follow manufacturer procedure); remove timing covers; mark timing positions; loosen and remove the timing belt; remove the old sprocket and fit the new unit; reassemble ensuring timing marks remain aligned; fit a new belt, tensioner and idlers as recommended; torque fasteners to manufacturer specifications and verify timing before running the engine. Use proper tools (timing lock tools, torque wrench) and follow the service manual for torque values and sequence.

Recommended Maintenance
Inspect The Sprocket During Every Timing System Service. Timing belt replacement intervals vary by model and engine variant; consult the vehicle’s maintenance schedule. When in doubt, replace the belt, tensioner and idlers together with any worn sprockets to avoid secondary damage. Always follow manufacturer procedures and torque specifications for assembly.
Why This Part Commonly Fails
- Wear And Tooth Degradation — long service life, contaminated oil or abrasive particles can accelerate wear.
- Corrosion Or Seizing — exposure to oil leaks or coolant can promote corrosion at the mounting bore or fasteners.
- Misalignment Or Worn Belt Components — a worn tensioner or idler may cause uneven loading and premature sprocket wear.
- Improper Installation — incorrect timing alignment or improper torque on the camshaft fastener can lead to failures.
Typical Vehicle Applications (Examples)
Commonly Used On Various Citroën And Peugeot Models Equipped With 1.6 HDi / 1.6 e-HDi Engines, For Example: Citroën C2, C3, C4, C5, Berlingo; Peugeot 206, 207, 307, 308, Partner. Compatibility Depends On Engine Variant And Production Date — Verify With The Part Numbers Above.
Final Notes
This part is most often found and ordered by its product codes 9657477580 and 0805H2. Fitment and proper installation directly affect engine timing and performance — if replacing the sprocket, consider simultaneous replacement of the timing belt system components to ensure long-term reliability.
