This is a Genuine Nissan harmonic balancer, also known as a crankshaft pulley, designed for the Nissan Patrol Y61 GU series fitted with the RD28ETI engine. Mounted to the front of the crankshaft, its primary function is to dampen harmful torsional vibrations produced by the engine. It also serves as the main pulley to drive accessory belts for components like the alternator, water pump, and power steering.
Replacement is necessary when the integrated rubber dampening element degrades, cracks, or separates from the steel hub due to age, heat, and stress. This failure compromises the balancer's ability to absorb vibration, which can lead to a rough-running engine and potential damage to the crankshaft and its bearings. Visible wobbling of the pulley or damage to the keyway are clear indicators that the balancer needs immediate attention.
Replacing the harmonic balancer is a job best suited for a workshop. The process requires the removal of the drive belts, and a specialized puller tool is highly recommended to safely remove the old balancer without damaging the crankshaft. Access can be tight, sometimes requiring the removal of the radiator for adequate clearance.
We also strongly recommend replacing the front crankshaft seal while the balancer is off to prevent future oil leaks. This is an ideal opportunity to inspect and replace your drive belts if they show signs of cracking or wear.
