Secure your engine’s harmonic balancer with this Genuine Nissan Harmonic Balancer Bolt, designed to suit Nissan Patrol GQ Y60 and GU Y61 models fitted with RD28 diesel and RB30 petrol engines. This OEM bolt is located at the front of the crankshaft and secures the harmonic balancer pulley in position, allowing it to correctly dampen engine vibrations and maintain reliable crankshaft operation.

Over time, the original harmonic balancer bolt can weaken, stretch, or become damaged due to repeated exposure to engine vibration, high torque loads, and age. A loose or failing bolt can allow the harmonic balancer to move, causing vibration, pulley misalignment, and potentially serious damage to the crankshaft and surrounding engine components. Replacing it with a Genuine Nissan component restores the correct clamping force and helps maintain long-term engine reliability.
