This Genuine Nissan bolt is used to secure the harmonic balancer, also known as the crankshaft pulley to the engine damper. It is a critical, high-torque fastener that ensures the balancer remains securely in place during operation.
This bolt may need to be replaced if it has been removed during engine servicing, such as replacing the harmonic balancer, timing cover seal, or timing belt/chain. These bolts are often designed as 'torque-to-yield' (TTY), meaning they stretch upon initial installation and are not intended for reuse. Reusing an old, stretched bolt can lead to incorrect clamping force and eventual failure.
If this crucial bolt is not replaced when required, or if it fails due to fatigue, it can loosen over time. This will cause the harmonic balancer to wobble, leading to severe vibrations, shredded drive belts, and damage to the crankshaft keyway and snout. In a worst-case scenario, the balancer can completely detach from the engine while it's running, causing catastrophic damage to the radiator, cooling fan, and other engine bay components, resulting in an extremely costly repair.
