COUPLING

The Drive Coupling (C5NN4N064A) is a mission-critical drivetrain component engineered to restore the mechanical reliability and power transmission of your Ford 5000 series tractor. Replacing OEM numbers C5NN4N064A and 1812261, this coupling acts as the vital bridge between your tractor’s power source and the driven components, such as the hydraulic pump or PTO drive assembly.

In tractors subjected to years of intensive labor, the drive coupling is often the first point of failure due to the immense shear forces and cyclical loads it must endure. Worn splines or a fatigued coupling can lead to drivetrain "chatter," loss of hydraulic pressure, or catastrophic slippage under load. This high-strength replacement provides the precise geometry and structural integrity required to eliminate drivetrain "slop" and restore your tractor’s factory-standard responsiveness.

Targeted Compatibility: Specifically engineered for the Ford 5000 series. By choosing an OEM-quality replacement, you are ensuring that your power delivery remains stable, reducing the risk of downtime during critical planting, plowing, or harvesting seasons.

Built for strength, balanced rotation, and maximum service life, this farm equipment replacement part helps maintain the integrity of your tractor's vital internal systems, ensuring your machinery performs consistently and safely under all field conditions.
