What size tracks does a Bobcat compact track loader use?

Expert Answer

Most Bobcat compact track loaders use either a 320 mm or 450 mm rubber track, but the correct fit is not just the width. You also need the pitch and link count, because Bobcat undercarriage parts are model-specific and a 320 mm or 450 mm track with the wrong core or guide geometry will not fit properly.

In practical terms, many smaller Bobcat T-series machines use B320 tracks, while larger models use B450 tracks. A common factory format is width × pitch × links, such as 320 × 86 × a model-specific link count or 450 × 86 × a model-specific link count. Exact fit can vary by machine family, year, and serial-number range, so the safest way to identify the track size is to read the code molded into the inside of the existing track or match the machine serial number.

Typical symptoms of the wrong size or worn track include poor tension retention, rubbing on the undercarriage, uneven wear on the lugs, de-tracking, or a track that looks correct by width but does not seat correctly on the sprocket and idlers. Before ordering, confirm three measurements: track width, pitch, and number of links. Also check whether your machine uses a standard or narrow configuration, since some Bobcat compact track loaders are available with different undercarriage setups.

Avoid guessing by outside width alone, and do not mix up a CTL track with a skid steer tire size or a generic metric size.
