What rubber tracks fit 450x163x38 machines?

Expert Answer

450x163x38 is a rubber track size, not a machine model, so the fit depends on the exact excavator or compact track loader. To replace it correctly, the machine must match all three numbers: 450 mm width, 163 mm pitch, and 38 links, plus the right guide style and tread pattern for the undercarriage.

This size is commonly found on some mini excavators, but it is not universal. The safest way to confirm compatibility is to check the size molded into the old track sidewall, then compare it with the machine serial plate or parts book. If the track is worn or missing, measure the width across the tread, count the links, and verify the pitch between drive lugs/pins. A mismatch in pitch or link count can cause poor tension, derailment, faster wear, and extra stress on rollers and sprockets.

Also check the condition of the undercarriage before ordering. Worn sprockets, rollers, or idlers can make a new track wear out early even if the size is correct. Common signs of a poor fit include the track running too tight or too loose, rubbing the frame, climbing the sprocket improperly, or tracking unevenly side to side. If you are choosing between tread styles, match the ground you work on: general-purpose patterns for mixed use, more aggressive patterns for mud and soft soil, and flatter patterns for surfaces where less marking matters.

Avoid ordering by brand name alone or by a machine nickname. Many OEMs use similar-looking track sizes across multiple models, and small differences in guide profile or carcass design can matter. If you send the machine model and serial number, VANROCK can help identify the correct replacement track. VANROCK supplies rubber tracks through an appointed dealer network and quotes pricing on request. If your machine is a Komatsu, note that VANROCK is an independent manufacturer and is not affiliated with Komatsu.
