Boom ram rod mounting pin 326-0089 CAT, aftermarket

Boom ram rod mounting pin 326-0089 is an aftermarket part for the Caterpillar backhoe loaders. According to the product card, this part is a boom ram rod mounting pin.

A joint pin is a hardened steel shaft that connects two parts (boom, dipper, bucket, hydraulic cylinder or link) and forms the axis on which they pivot. The pin runs in a bush and carries all the forces of digging and loading. If greasing is neglected or the bush is worn, the pin surface becomes scored and play develops in the joint, causing knocks as the bucket moves, loss of precision and ovalled eyes.
