Genuine Nissan Harmonic Balancer YD25 - Nissan Navara D40 & Pathfinder R51

This is a Genuine Nissan harmonic balancer, also known as a crank pulley, designed for Nissan Navara D40 and Pathfinder R51 models equipped with the YD25 engine. Located on the front of the engine's crankshaft, its primary function is to absorb and dampen torsional vibrations, protecting critical engine components from damage. This is a direct replacement for the original factory-fitted part.

Replacement is necessary when the original balancer shows signs of failure, such as cracking, warping, or when the rubber dampening element begins to separate from the metal hub. A faulty balancer can be identified by excessive engine vibrations felt in the cabin, unusual noises from the engine bay, or a visible wobble from the pulley while the engine is running.

Installation Notes 

Installation of a harmonic balancer is considered a moderate to advanced task and is best performed in a workshop. It requires specialised tools, including a crankshaft holding tool to prevent the engine from turning and a high-range torque wrench to correctly tighten the main crankshaft bolt to factory specification. It is highly recommended to inspect the drive belts and the front main crankshaft seal when replacing the harmonic balancer, as these are often replaced at the same time to prevent future component failure or oil leaks.
