The track chain: the #1 wear part on a Caterpillar D11
On a 100+ tonne dozer, the undercarriage accounts for up to 20% of the machine price and 50% of lifetime maintenance cost. The track chain wears fastest — links, pins and bushings run constantly in abrasive ground. Replacing the chain at the right time, rather than waiting for failure, is the most profitable undercarriage decision on a D11.
