GEAR RH

The Right-Hand Axle Gear (C5NN4236A) is a mission-critical drivetrain component engineered to restore the pulling power and mechanical efficiency of your classic Ford tractor. Replacing OEM numbers C5NN4236A and 1803445, this gear is designed to handle the rigorous demands of professional agricultural machinery, providing reliable power delivery from the differential to the axle.

In tractors with thousands of hours of service, the axle gears are the primary points of contact for transferring engine torque to the ground. Over time, original gears can develop pitting, tooth fatigue, or spline wear, which leads to "slop" in the drivetrain, noise, and potential failure. This high-strength replacement gear provides the precise tooth geometry and structural rigidity needed to restore factory-standard performance.

Targeted Compatibility: Specifically engineered to fit a wide array of Ford tractor models. By choosing an OEM-quality replacement, you are ensuring that your differential remains stable and responsive, reducing the risk of catastrophic drivetrain failure during critical planting, plowing, or harvesting tasks.

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 load conditions.
