Which rubber tracks fit the Komatsu PC38-2 AVANCE R, and what VANROCK option is available?

Expert Answer

For the Komatsu PC38.2 AVANCE R, VANROCK supplies a rubber track under part code VRT300X52.5X84N, with a verified weight of 139.00 kg. If you are replacing both sides, match the machine model exactly and confirm the track dimensions on the old belt before ordering.

Because this is an OEM machine model, a good fit check is still important: compare the width, pitch, and link count on the existing track, plus the overall wear on the sprocket, idler, and rollers. A worn undercarriage can shorten track life or make a new belt run incorrectly.

VANROCK sells through an appointed dealer network, and pricing is quoted on request. If you want the right fit confirmed for your PC38.2 AVANCE R, use the dealer network with the machine model and this part reference.
