Genuine Nissan Crank Gear Sprocket YD25 - Nissan Navara D22, D40 & Pathfinder R51

This is a Genuine Nissan crank gear sprocket designed for Nissan Navara D22, D40, and Pathfinder R51 models fitted with the YD25 engine. Located on the front of the engine's crankshaft behind the harmonic balancer, this sprocket is a critical component that drives the timing chain, ensuring the engine's camshafts are correctly synchronised with the crankshaft's rotation.

As a key wear item, the hardened teeth on the crank gear can wear down or break over time due to normal engine operation. A worn or damaged sprocket can lead to incorrect engine timing, resulting in poor performance, a rough idle, or a no-start condition. It is highly recommended that this gear be replaced as part of a complete timing chain service or if the harmonic balancer has failed or been removed.

Product Features

• Genuine Nissan Quality: Manufactured to exacting OEM standards for precise fitment and performance, ensuring reliability under tough Australian conditions.
• Direct-Fit Replacement: A direct swap for the original factory gear, guaranteeing correct engine timing is restored without any need for modifications.
• Engine Health: Using a genuine sprocket is crucial for preventing incorrect timing, premature wear on other components, and the risk of catastrophic engine failure associated with inferior parts.

Installation Notes 

Replacing the crank gear sprocket is a complex workshop job that requires significant engine disassembly and specialised tools. Accessing the gear involves removing the harmonic balancer and timing covers. Professional installation is recommended to ensure correct timing alignment upon reassembly. It is common to replace the timing chains, guides, tensioners, and related seals at the same time as the crank gear.
