Crankshaft Timing Gear - Type 4 Engines

This genuine Volkswagen steel crankshaft timing gear is designed for all air-cooled Type 4 engines fitted to Baywindow Buses and early Type 25 (T3) Buses, as well as Porsche 914 models. It is suitable for 1700cc, 1800cc, and 2000cc Type 4 engines, ensuring correct and reliable valve timing.

The crankshaft timing gear is a critical internal engine component that transfers rotational drive from the crankshaft to the camshaft via the timing gears. This precise relationship controls when the valves open and close in relation to piston movement. Any wear or damage to this gear can result in incorrect valve timing, poor engine performance, increased noise, and in severe cases, internal engine damage.

Manufactured from hardened steel, this gear offers excellent durability and resistance to wear, making it ideal for engine rebuilds or replacement of worn or damaged originals. As a genuine Volkswagen part, it is produced to original factory specifications, ensuring correct fitment on the crankshaft and accurate meshing with the camshaft gear for smooth, quiet operation.

This timing gear is a press-fit onto the crankshaft and should be installed using correct workshop procedures, typically during a full engine strip-down or rebuild.
