Secure your harmonic balancer correctly with this Genuine Nissan Harmonic Bolt, Washer and Woodruff Keys kit, designed to suit Nissan Patrol GQ Y60 and GU Y61 models fitted with the RD28 or RB30 engines. These OEM components secure the harmonic balancer to the crankshaft, a critical connection that keeps the balancer precisely timed and firmly attached at the front of the engine.

Over the kilometres, the bolt, washer and woodruff keys can wear, stretch, or even break. This can lead to vibration, timing issues, and potentially serious engine damage if not addressed. Replacing the complete kit together ensures every component securing the balancer is fresh and correctly rated, rather than reusing stretched or worn hardware alongside new parts.

Manufactured to Genuine Nissan specifications, this kit is built with a high-tensile steel bolt for durability and clamping force, a washer to properly distribute clamping load and protect surfaces, and steel woodruff keys to securely locate the harmonic balancer to the crankshaft. It's the complete, correct solution for harmonic balancer removal, timing work, or crankshaft pulley servicing on your Nissan Patrol.
