Look Inspecting Excavator

Movement or Play

A slew ring that is damaged can be a costly item to replace or repair in used hydraulic excavators. Thus, the hydraulic excavator housing must be rotated to a quarter turn and checked for any slew ring movement or play. Also, try to find movement or play at the connection points of the bucket, stick and bottom. Ideally, all bushings and pins must be tight. Any loose connections, especially those at the connection points between the bucket and excavator stick, could indicate a loss in the accuracy of the excavation and a need for repairs.

This is especially true if they are present in major connection point welds like between the stick or stick, bottom and bucket. The presence of significant bends or racks could indicate the overall structural integrity of the excavator has been negatively impacted and the stick or book will have to be replaced.

Leaks

The hydraulic pump compartment should be opened to find sings of leaks. Check all lines, houses and cylinders. Additionally, check for leaks in the swing bearing or slew ring that could forewarn of too much movement or play. Leaks must be repaired right away to guarantee continued and safe operation of the excavator.

Leaks

Broken or Inaccurate Hours Meter

When the hours meter does not operate or gives questionable reading, check for wear in the control pedals. Excessive wear could mean that the excavator operates for more hours than expected.

Scalloping

Signs of scalloping and half-mooned shape can be seen between the excavator bucket teeth. Scalloping doesn’t have to mean a bucket must be replaced. However, it indicates a minimized cutting force.

Availability of Used Parts

Before buying a used excavator, it is important to ask the dealer if the used parts are available. Get in touch with suppliers if your dealer cannot help. Remember that choosing the wrong old excavator and parts have serious consequences. For instance, a wrong hydraulic pump will result in weakening of the entire system since it fails to properly hold the pressure. Similarly, as you choose used excavator teeth, go for sharp and strong ones only. Otherwise, your excavator is unlikely to perform well. If possible, buy excavator parts that are newly new and can work on all vital functions.
