Maintain correct crankshaft timing and secure harmonic balancer alignment with this Genuine Nissan Harmonic Woodruff Key, designed to suit Nissan Patrol GU Y61 TB48 4.8L Petrol and Y62 VK56 5.6L Petrol models. This OEM harmonic key locates the harmonic balancer (crankshaft pulley) onto the crankshaft, ensuring precise alignment and preventing movement during engine operation.

The harmonic woodruff key is a small but critical engine component that is subjected to constant engine torque and vibration. Over time, it can become worn, fatigued or damaged, particularly if the harmonic balancer has become loose or has been removed during engine repairs. A damaged harmonic key can allow the harmonic balancer to slip on the crankshaft, resulting in incorrect timing, excessive engine vibration and potential crankshaft damage. Replacing a worn key helps restore correct harmonic balancer alignment and protects your engine from costly repairs.

Manufactured to Genuine Nissan specifications, this harmonic woodruff key provides precise fitment, exceptional strength and long-lasting durability. It is the ideal replacement during harmonic balancer installation, front engine repairs or complete engine rebuilds.
