The Crankshaft Pulley Screw M1614.560 is a critical high-strength fastener designed for the precise and secure attachment of the crankshaft pulley to the engine’s crankshaft. This specific component plays a fundamental role in maintaining the integrity of the engine’s front end accessory drive system. Its dimensions—M16 indicating a 16mm thread diameter, 14.5mm likely referring to the thread pitch or a specific shoulder dimension, and 60mm denoting the overall length—are engineered to exacting OEM specifications to ensure a perfect fit and optimal clamping force.

Constructed from high-grade alloy steel and often undergoing heat-treatment processes, this screw is built to withstand immense tensile and shear stresses, as well as constant vibrational forces generated by engine operation. A failure of this component can lead to catastrophic engine damage, resulting in the loss of accessory drive functions like the alternator, power steering pump, and water pump. Therefore, using a correctly specified, high-quality replacement is paramount during any repair or service involving the crankshaft pulley, harmonic balancer, or timing cover.

When installing the Crankshaft Pulley Screw, it is essential to follow the manufacturer’s recommended torque procedure precisely. This typically involves cleaning the threads, applying the correct thread-locking compound if specified, and using a calibrated torque wrench to achieve the exact clamping load. Over-torquing can lead to thread stripping or bolt failure, while under-torquing may result in loosening and eventual separation. This genuine-specification fastener guarantees the reliability, safety, and longevity of your engine’s core assembly, making it an indispensable part for professional mechanics and discerning DIY enthusiasts.
