Description
Crankshaft timing sprocket for CITROËN and PEUGEOT with 1.4 HDi and 1.6 HDi engines. Timing pinion for the engine.
Original Stellantis OE numbers 9810698080 / 0805E5. This crankshaft timing sprocket (toothed pinion) is designed to drive the timing belt/chain and to ensure precise synchronization between the crankshaft and camshaft on 1.4 HDi and 1.6 HDi engines. The part is suitable for professional workshops and experienced DIY mechanics looking for a reliable OE-referenced replacement. Common search keywords: crankshaft sprocket 1.6 HDi, timing pinion 9810698080, crankshaft pulley 0805E5, Citroën timing sprocket, Peugeot timing sprocket.
Function: The sprocket transmits rotational motion from the crankshaft to the timing system. It keeps valve timing accurate and works together with the timing belt/chain, tensioner and camshaft sprockets. Correct tooth profile and secure mounting are essential to prevent timing errors, engine misfire or mechanical interference.
When To Replace: Replace the sprocket if teeth show wear, if the keyway or hub is damaged, or when replacing the timing belt/chain and related components. On HDi engines it is recommended to inspect and often replace timing components at the manufacturer service interval (typically around 100,000–120,000 km depending on the model and service history).
Compatibility And Typical Models: Fits 1.4 HDi and 1.6 HDi engine families used in various Citroën and Peugeot models. Examples of commonly compatible vehicles include Citroën C2, C3, C4, Berlingo and Peugeot 206, 207, 307, Partner. Verify engine type and part number prior to installation to ensure correct fitment.
Installation Recommendations
- Replace The sprocket together with the timing belt/chain, tensioner and idler pulleys as part of a complete timing service to avoid premature failures.
- Use Proper Tools: Timing locking tools, torque wrench and appropriate puller/installer tools are recommended to avoid damage to the hub or crankshaft.
- Alignment: Always align the engine timing marks precisely before removing the old sprocket and confirm correct mark alignment after installation.
- Fastening: Use a new crankshaft bolt if specified by the manufacturer and tighten to the manufacturer’s torque specification. Do not reuse stretched or damaged fasteners.
- Inspection: Check the crankshaft front oil seal and replace if leaking. Clean the mounting surface thoroughly to ensure a concentric fit.
- Safety: Disconnect the battery and follow the vehicle manufacturer’s procedures for disassembly/assembly to prevent injury and component damage.
Most Common Failure Causes
- Tensioner Or Belt/Chain Wear: Excessive play or a failed tensioner allows uneven loading that accelerates tooth wear.
- Corrosion Or Contamination: Oil leakage or debris on the sprocket accelerates wear and may damage belt/chain teeth.
- Improper Installation: Incorrect timing alignment, reused bolts or damaged mounting faces can lead to wobble, loosening or premature failure.
- Age And Fatigue: High mileage and long service intervals cause material fatigue and loss of precise tooth profile.
