Do you supply undercarriage parts for Komatsu machines?

Question

VANROCK Track Solutions · Accepted Answer

Yes. VANROCK supplies undercarriage parts for a wide range of Komatsu machines, including excavators, dozers, and Komatsu Utility mini excavators. Our range covers the main wear items you would expect for tracked equipment: track chains, complete track groups, track shoes, track and carrier rollers, idlers, sprockets and segment groups, rubber tracks, rubber pads, and track bolts and nuts.

If you are checking fitment, the most useful details are the exact machine model and serial number, because Komatsu machines can vary by undercarriage series, shoe width, pitch, and roller layout. For example, a part that fits one PC excavator or D-series dozer may not fit another unit of the same family without confirming the undercarriage configuration. Knowing whether the machine runs steel tracks or rubber tracks also helps narrow the right components quickly.

Common signs that parts need attention include chain stretch, uneven track wear, cracked or loose shoes, noisy rollers, worn sprocket teeth, or an idler that no longer keeps proper tension. If you are replacing one major component, it is often worth checking the related wear parts at the same time so the new part is not damaged by a worn mate component.

A few practical points can help avoid mistakes: • do not match only by machine name; confirm model and serial number • check pitch, bush type, and shoe width before ordering • inspect both sides of the undercarriage, since wear is often uneven • replace bolts and nuts when the joint hardware is worn or stretched • compare wear across chains, rollers, idlers, and sprockets before deciding whether to replace individually or as a set.
