How to measure the undercarriage on used machines?

Is this service included in an Mevas inspection?

Yes, on request and for larger machines this service is included for tracked machines from Caterpillar. We do measure all components. Remaining life values will be calculated with the CAT CTS Undercarriage Handbook. When inspecting machines of other brands, we assess the remaining service life based on our experience. Click here for our video explaining the measurement of the undercarriage step by step.

Since the undercarriage is one of the most expensive components on these machines and can be very expensive to replace, we recommend special attention to inspection here. If you are looking to buy a second hand machine in Europe – get the remaining life of the U/C confirmed by MEVAS.

Which tools can be used to measure U/C components?

To measure undercarriage components of a track type tractor or an excavator, the following tools can be used:

  1. Track Gauge or meter – It is used to measure the track gauge, or the distance between the tracks, to ensure that it is within the manufacturer’s specifications.
  2. Track Roller Caliper – It is used to measure the diameter of the track rollers and the wear on the bottom of the track roller.
  3. Idler Pin Gauge – It is used to measure the idler’s diameter and the wear on the idler’s bearing surfaces.
  4. Ultrasonic Gauge – It is used to measure the thickness of the track links and the wear on the bushings.
  5. Chain Wear Gauge – It is used to measure the wear on the track chain and to determine if the chain needs to be replaced.
  6. Shoe Height Gauge – It is used to measure the wear on the track shoe and to determine if the shoe needs to be replaced.

By using these tools, it is possible to accurately measure the wear on the undercarriage components and determine when they need to be replaced or repaired, which helps to extend the life of the track type tractor and reduce maintenance costs.
