Saab Crankshaft Timing Gear - INA 12645465

Product Information

An engine timing crankshaft gear is a precision-machined gear mounted on the crankshaft that drives the timing chain or belt to synchronize the crankshaft and camshaft rotation. This ensures the engine’s valves open and close at the correct time relative to piston movement, allowing efficient combustion and preventing internal damage. A properly functioning crankshaft gear is essential for smooth engine operation and long-term reliability.

• Rattling or knocking noises from the timing area, often due to worn or damaged gear teeth.
• Engine misfires or poor performance, caused by incorrect valve timing.
• Failure to start or severe engine damage, if the gear slips or breaks completely.
