How to measure the undercarriage on used machines?

Posted on by in English posts

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.

Did you ever measure undercarriage components to know their remaining life?

The most expensive and most important assembly when evaluating a bulldozer is certainly the undercarriage. Therefore, when inspecting bulldozers, we pay special attention to the condition of the undercarriage. We have reference values for Caterpillar machines and measure all components. This allows us to accurately determine the remaining service life. We have created an instruction in which we explain our procedure step by step. Click here to watch it. After watching you know what to look for when measuring the track shoes, sprockets, track links, bushings and idlers. If you are not sure about measuring or have any questions – just contact us.

Do not forget to check

Other important points when inspecting a used dozer are the play in the joints and bearings, especially in the so-called equalizer bar. This cross member connects the right and left undercarriage frames on many bulldozers. Together with the pivots in the rear area of ​​the drive frame, this cross member enables the drives to move horizontally. If you want to know more – get here to a short film. Make sure  that you look for these points, otherwise very expensive repairs may become necessary.

If you need assistance in evaluating used machines, Mevas technicians can help you. We are trained for the special requirements when inspecting second-hand machines. We view a machine as you would as a buyer. Small things are noted, but not highly weighted. However, we thoroughly examine the condition of the expensive and important components.
