Caterpillar 321B

Pins and Bushings are key elements for a good functioning of the joints of arms and buckets of any excavator. These components in fact preside over the entire range of movements of the machine: placed in all the fundamental joints of the excavator, it is on them that the precision of the work depends. Due to their activity, pins and bushings are subject to a natural process of wear, and for this reason they must be suitably replaced.
