Motorcraft (Ford) Camshaft Timing Adjustment Bolt 3L3Z-6279-DA

Camshaft phaser bolt Motorcraft (Ford) 3L3Z-6279-DA

Original timing mechanism fastener Motorcraft (Ford) with part number 3L3Z-6279-DA is designed specifically for rigid securing of the camshaft phaser sprocket (VCT) to the camshaft. This component was engineered by Ford Motor Company engineers to ensure flawless precision of the variable camshaft timing system operation on three-valve engines of the Triton and Modular families. The use of original fasteners guarantees correct torque transmission, prevents timing displacement, and protects mechanical engine components from critical damage.

Design features and engineering purpose

This specialized fastener element is manufactured from a high-strength steel alloy and belongs to the category of single-use torque-to-yield (TTY) fasteners. When tightened to the manufacturer-specified torque, the part stretches within the plastic deformation zone, providing constant clamping force under any thermal expansion. An internal high-pressure oil passage inside the part ensures uninterrupted motor oil delivery to the phase regulator mechanism, guaranteeing sharp and smooth operation of the entire VCT system.

Key advantages of the original element

• Strict compliance of geometric parameters and thread pitch with Ford factory technology standards.

• High resistance to shear and cyclic dynamic loads at high engine speeds.

• Factory anti-corrosion phosphate surface treatment to prevent seizing.

• Built-in internal channel for transporting pressurized lubricant to the phaser.

• Integrated flange washer for even clamping pressure distribution across the sprocket surface.

Since the fastener operates under extreme vibrational and thermal loads, its reuse after removal is strictly unacceptable. Secondary installation of a used part leads to tension loss, thread breakage, phaser failure, and costly repair of the entire cylinder head.

Detailed compatibility table by make, model, and year

Timely replacement of timing mechanism components with original Motorcraft parts during scheduled maintenance or major overhaul guarantees stable engine operation, preservation of factory power output, and optimal fuel efficiency.
