BMW 640i arriving for BMW Timing Gear Replacement

Hi Everyone,

The function of your BMW timing gears is to allow the camshaft and crankshaft to turn the timing chain. The pistons are moved up and down by the turning of the crankshaft which also allows the intake and exhaust valves on the cylinders to open and close. These components are important for optimum engine timing.

As the piston moves downward, the intake valves open to allow fuel and air into the cylinders. As the piston moves upward, the exhaust valves open to expel exhaust air from the cylinders.

If the intake valves are not functioning properly, the correct air/fuel mixture will be able to enter into the cylinders. If the exhaust valves are not opening and close properly, exhaust air will be trapped inside the cylinder.

If the timing gears are failing, the valve timing and ignition timing will not be accurate. Noises from the engine compartment may occur, causing the engine to run rough, backfire or stalled.

We hope you will enjoy viewing the following pictures.

Preventive maintenance is always better than repair. It is important to understand about wear and tear before the components break down totally.
