The crankshaft gear wheel is installed on the front of the crankshaft and is responsible for driving the timing belt system that synchronizes the rotation of the crankshaft with the camshaft. In Porsche 944 and 968 engines, this gear forms the primary drive point for the timing system, ensuring that valve timing remains precisely aligned with piston movement.
Fits:
Porsche 944 1986-1991 with engine types M 44.40 and M 44.41
Porsche 968 1992-95 with engine types M 43 and M 44.

This OE Match version of part number 94410512507 is designed to match the factory specifications used in Porsche engines, providing accurate tooth geometry and reliable engagement with the timing belt and associated components.
The crankshaft gear transfers rotational motion from the crankshaft to the timing belt system. This ensures the camshaft opens and closes the engine valves at the correct time relative to piston movement, maintaining proper combustion and engine performance.
If the gear becomes worn or damaged, the timing system may lose accuracy, which can affect engine efficiency and reliability.
Function
• Timing Drive: Transfers crankshaft rotation to the camshaft timing system
• Engine Synchronization: Maintains precise timing between pistons and valves
• Power Transmission: Drives the timing belt mechanism
• Engine Reliability: Ensures stable and accurate valve timing
Timing system components are subjected to constant load and engine vibration. Over time the gear teeth may wear or become damaged, which can affect timing belt alignment and engine timing accuracy. Replacing the crankshaft gear during major engine service or timing system overhaul helps ensure precise timing operation and protects other components in the engine’s timing system.
Consider replacing the crankshaft gear wheel when:
• Performing a timing belt or engine rebuild service
• Gear teeth show wear or damage
• Timing system components are being replaced
• Engine timing alignment issues are detected
