Product Description:
Timing Belt Pulley
OE NO.: 31370602 31370610
Applicable vehicle type: For VO LVO
The automotive timing pulley (or timing gear) serves as the core transmission component within the engine's valve timing system. It is categorised into two primary types: the timing belt pulley (or synchronous belt pulley) and the timing chain sprocket, each designed for compatibility with either a timing belt drive system or a timing chain drive system. Their primary function is to precisely synchronise the rotational movements of the crankshaft and camshaft, ensuring the coordinated operation of valve opening/closing and piston movement at the correct moment. They serve as the engine's ‘timekeepers’, ensuring efficient, stable, and safe operation.
Rapid Diagnostic Methods
- Visual Inspection: Check for tooth surface wear, cracks, or broken teeth; verify clarity of timing markings
- Shake Test: Inspect sprockets/pulley wheels for radial/axial play to assess bearing failure
- Austensitisation: Listen at idle for metallic ‘clack-clack-clack’ or ‘whine-whine’ friction noises, indicating possible timing gear failure
- Professional inspection: Use diagnostic tool to read VVT system fault codes; employ timing tool to check valve timing deviation
