What track link fits the Komatsu PC400-1/5?

Expert Answer

For the Komatsu PC400-1/5, the correct track link depends on the full track chain specification, not just the model name. In practice, you should match the machine serial number, chain pitch, pin diameter, bushing type, and shoe width so the link set fits the existing undercarriage correctly.

VANROCK supplies track chains and track chain components for Komatsu machines through our appointed dealer network, with quotations provided on request. If you are replacing a worn chain, it is best to check whether you need a complete track chain assembly, individual links, or a matched pin-and-bushing set. A worn sprocket, idler, or roller set can also shorten the life of new links, so inspecting the full undercarriage first is important.

Komatsu is an OEM brand name used here only for identification; VANROCK is an independent manufacturer and is not affiliated with Komatsu. If you share your machine serial number or the measurements from the old chain, a dealer can help identify the right replacement more accurately.
