ATJ4279 Front Axle Trunnion Pin for Nuffield, Leyland and Marshall Tractors

Quality replacement front axle trunnion pin with a hard chrome finish to provide increased wear resistance and a longer service life.

The trunnion pin forms the main pivot point of the front axle, allowing the axle to oscillate over uneven ground while supporting the weight of the tractor. Over time, both the pin and bushes can wear, resulting in excessive axle movement and poor steering performance.

Additional Information

The trunnion pin and bushes are wear components within the front axle assembly. As they wear, the front axle can develop excessive movement, leading to poor steering characteristics and accelerated wear of surrounding components.

For the best long-term repair, we recommend replacing the two NT3004 bushes at the same time as the trunnion pin. Reusing worn bushes with a new pin will significantly reduce the life of the new component.

The hard chrome finish provides increased resistance to wear compared with a standard steel pin, making it an excellent choice for both working and restored tractors.
