What Does This Du Bush Do?
DU bushes (dry-running composite bushings) are self-lubricating plain bearings pressed into pivot pin bores on excavator linkages — boom foot pins, arm-to-boom pins, bucket linkage pins, and blade lift arms. The PTFE-lined bearing surface eliminates the need for frequent greasing and resists wear under heavy cyclic loading.
Possible Du Bush Problem Symptoms
If your machine is showing any of the following, a faulty du bush may be the cause:
- Knocking or clunking noise from a linkage pin joint during bucket or arm movement
- Visible play or looseness in a boom, arm, or bucket pivot point during operation
- Uneven or jerky linkage movement caused by a seized or collapsed bush
- Accelerated wear on the pin or bore caused by a bush that has worn through its lining
