How can I tell if a boom pivot joint is worn?

With the bucket resting on the ground, gently rotate the boom: a knock or visible play at the boom foot signals wear. Start by replacing the pins and bushings. If play persists with new parts, the pivot joint bushings are ovalled and the part must be replaced.

Is it possible to repair a cracked pivot joint?

Minor cracks can sometimes be repaired by welding, provided the area is properly prepared and the part is inspected afterward. On a stress-bearing area of the boom, a poorly done weld will crack again. An original used pivot joint inspected in workshop avoids this risk and lengthy downtime for repairs.

What is the price of a used pivot joint?

The price mainly depends on the size of the machine: a pivot joint for a 3-ton mini excavator doesn’t have the weight or value of one for a wheeled excavator. Some stock items list prices as-is on the product page. Others are priced on request, after verifying the model and bushings condition.
