Crankshaft Pulley Bolt – Ford (HL3Z-6A340-A)

The Crankshaft Pulley Bolt – Ford (HL3Z-6A340-A) is a Genuine OEM fastener engineered to meet the exact strength, thread tolerance, and torque specifications established by Ford. This bolt plays a critical role in securing the crankshaft pulley (harmonic balancer) to the crankshaft, ensuring proper engine timing, accessory drive alignment, and vibration control.

Manufactured from high-strength, automotive-grade steel, this crankshaft pulley bolt is designed to withstand extreme torque loads, rotational forces, and continuous engine vibration. The OEM material and heat-treatment process provide the correct tensile strength and elasticity required for a torque-to-yield application where specified, reducing the risk of bolt stretch failure, loosening, or pulley misalignment.

Designed to exact factory specifications, the HL3Z-6A340-A bolt offers precise thread pitch, length, and seating surface to ensure correct engagement with the crankshaft. Proper fitment is essential for maintaining correct pulley alignment and preventing damage to the crankshaft or accessory drive system. Professional technicians benefit from predictable installation and accurate torque application, while DIY mechanics can perform repairs confidently when following factory procedures.

From a performance and reliability standpoint, using the correct OEM crankshaft pulley bolt is critical. Reusing old bolts or installing incorrect hardware can lead to pulley slippage, vibration issues, or catastrophic engine damage. Replacing the bolt during pulley or front-engine service helps restore factory-level security and long-term reliability.
