What the numbers mean on a New Holland E25SR
- 300x52.5x76 — 300 mm tread width (about 12"), 52.5 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 New Holland E25SR
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:

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.
