Komatsu PC12 Avance R tracks — what rubber track size fits this machine?

Expert Answer

The Komatsu PC12 Avance R commonly uses rubber tracks in the 300x52.5x76 size, but the correct fit should always be confirmed by measuring your existing track or checking the machine serial number. VANROCK supplies replacement rubber tracks through its appointed dealer network and quotes are provided on request.

For a proper match, verify three details: width, pitch, and number of links. On mini excavators like the PC12 Avance R, a small difference in pitch or link count can cause fitment problems, poor tension, or premature wear. If your machine has had undercarriage changes before, do not rely on the model name alone. Measure the old track at the inner guide and count the drive lugs/links, or compare the OEM track code stamped on the track body.

If you are replacing both sides, inspect the sprocket, idler, and rollers at the same time. Worn sprockets or seized rollers can quickly damage new tracks. VANROCK is an independent manufacturer and is not affiliated with Komatsu.
