Application and Function in N47 / N47N Engines

The presented drive sprocket works with the oil pump in BMW diesel engines from the N47 and N47N family, used in series such as E87, E90, and F30. Its task is to mechanically transfer the drive from the timing system to the oil pump, ensuring adequate flow of lubricating fluid throughout the engine.

A functional drive sprocket in the oil pump is crucial for:

• maintaining proper oil pressure across the entire RPM range,
• stable lubrication of bearings, crankshaft, and timing components,
• reducing wear on cooperating parts under high load conditions,
• preserving the correct operation of the power unit over a long service life.

Technical Characteristics and Fitment

As a component from the sprockets group, the drive sprocket for the oil pump in N47 / N47N engines is designed for precise interaction with other gears in the system. The tooth profile, diameter, and mounting method are adapted to BMW's factory specifications, ensuring the correct geometry of the oil pump drive.

Proper fitment of this sprocket to a specific engine variant is important for:

• correct meshing with the driving gear,
• minimizing play and operational noise of the system,
• reducing vibrations transmitted to the oil pump,
• maintaining proper synchronization with other drive components.

Used Condition and Benefits of Choosing OEM Parts

The offered drive sprocket is a used component, originating from an original BMW drivetrain. For many users and workshops, this represents a sensible compromise between repair cost and maintaining factory part specifications. Original BMW components are designed for long-term cooperation with specific engines, which translates to predictable performance in operation.

Using a used OEM component can be particularly beneficial in situations where:

• quick availability of parts for N47 / N47N engine repairs is important,
• maintaining the original design of the lubrication system is crucial,
• the repair needs to be economical while maintaining parameters close to factory specifications.
