Rubber track sizes are written as three numbers: width x pitch x links, all measured in millimeters except links, which is a count. For example, 450x86x56 means a 450 mm wide track with an 86 mm pitch and 56 links.
Step 1: Look For The Size On Your Current Track
Most tracks have the size molded into the rubber, usually on the inside or the side of the track. Clean the area and look for a code like 320x86x52. If you can read it, that is the size you need.
Step 2: Measure The Width
Measure straight across the outside face of the track, edge to edge, in millimeters. Common compact track loader widths are 320 mm (12.6 in), 400 mm (15.7 in) and 450 mm (17.7 in).
Step 3: Measure The Pitch
Pitch is the distance from the center of one drive lug (or embedded steel link) to the center of the next. Measure across several lugs and divide for accuracy. For example, measure across 5 gaps and divide by 5. Most compact track loaders use an 86 mm pitch. Mini excavators often use 72 mm, 52.5 mm or other pitches.
Step 4: Count The Links
Count the drive lugs on the inside of the track all the way around. Mark your starting lug with chalk or paint so you do not count twice. The total is the link count.
Step 5: Note The Guide Type And Tread
Note your tread pattern (C-lug, multi-bar, block or zig-zag) and take a photo of the inside of the track. Some machines with the same size use different guide systems.
Still Not Sure?

Tip: if your sprockets, rollers or idlers are worn, replace them with your tracks. Worn undercarriage parts shorten the life of new tracks.
