How do I measure undercarriage wear percentage?

Expert_Answer

Undercarriage wear percentage is usually calculated by comparing the current measurement to the new part dimension or to the service limit in the OEM specification. For example, measure the relevant wear surface with a caliper or wear gauge, then use:

Wear % = [(new dimension - current dimension) ÷ (new dimension - service limit)] × 100

The exact method depends on the component, such as track chain pitch, roller diameter, idler tread, or sprocket tooth profile. Always measure at the correct points and under the machine conditions recommended by the manufacturer. Because undercarriage wear patterns can vary by application, a trained inspection is the most accurate way to judge remaining life. VANROCK supplies track chains, rollers, idlers, sprockets, shoes, and rubber tracks.
