Which rubber tracks fit the Komatsu PC45 M-1, and what VANROCK option is available?

Expert Answer

For the Komatsu PC45, VANROCK supplies a rubber track with part code VRT400X72.5X72N, and the verified weight is 221.00 Kg. If you are matching a replacement, that part code is the key reference to compare against your existing track markings and machine fitment details.

Before ordering, check the track width, pitch, and link count on the current track, plus the machine variant, because Komatsu PC45 fitment can vary by configuration. Also inspect the undercarriage for sprocket wear, roller wear, and idler alignment; worn components can shorten track life or cause tracking issues even when the size is correct.

VANROCK is an independent manufacturer and is not affiliated with Komatsu. VANROCK sells exclusively through an appointed dealer network, and exact fitment and pricing are quoted on request through that network.
