How To Measure Rubber Tracks
Rubber tracks are measured by width, pitch, link count, and sometimes guide type. A size such as 450x86x58 means 450 mm wide, 86 mm pitch, and 58 links.
Rubber Track Size Format
| Example | Width | Pitch | Links | Guide |
|---|---|---|---|---|
| 450x86x58 | 450 mm | 86 mm | 58 | Usually center guide / machine-specific |
| 300x52.5Nx80 | 300 mm | 52.5 mm | 80 | N guide |
| 400x72.5Wx76 | 400 mm | 72.5 mm | 76 | W guide |
Step 1: Check the Size Stamped on the Existing Track
The fastest method is to look for the size molded into the side of the existing rubber track. Clean the sidewall and look for a number pattern like 320x86x49, 450x86x58, or 300x52.5Nx80.
Step 2: Measure Track Width
Measure across the outside width of the rubber track in millimeters. Common skid steer widths include 320 mm, 400 mm, and 450 mm.
Step 3: Confirm Pitch
Pitch is the distance from the center of one drive lug to the center of the next drive lug. Common compact track loader pitch sizes include 86 mm and 100 mm. Mini excavator sizes often use 52.5 mm, 72.5 mm, 81 mm, or similar pitch values.
Step 4: Count the Links
Count every metal drive link around the inside of the track. Link count must match the machine’s undercarriage. A track with the wrong link count usually will not tension or fit correctly.
Step 5: Confirm Guide Type
Some sizes include guide letters such as N, W, B, or T. Do not treat guide letters as optional. A 400x86x52B and a 400x86x52T are not the same track.
