What the numbers mean on a Bobcat E80
- 450x81x76 — 450 mm tread width (about 18"), 81 mm pitch, 76 links
Width is the tread face, pitch is the distance between drive lugs, and links is the count around the loop. All three have to match — a track one link off will not tension correctly no matter how close the width is.

Undercarriage parts for the Bobcat E80
Rollers, idlers and sprockets wear on the same clock as the track. Fitting new rubber over a hooked sprocket or a seized roller is the fastest way to lose the new track — check these while the tracks are off:
- Bottom roller — 7004933
- Carrier roller — 7012275
How these wear
Excavator undercarriages load one side hard on slew and travel, so link cracking usually shows up before the tread wears out. Replace in pairs where you can: a new track running against a stretched one loads the drive unevenly and you will feel it in the steering.
Same track, other machines

Not sure which you are running? Read the size off the inside of the old track, or call (850) 816-7898 and we will pull it off the machine record. The Track Finder works by make and model too.
