Replacement rubber tracks for the Case CX31 mini excavator in 300x52.5Wx82 — 300 mm wide, 52.5 mm pitch, 82 links. Built for digging, trenching, backfill and tight-quarters work, with free freight to the lower 48.
What the numbers mean on a Case CX31
300x52.5Wx82 — 300 mm tread width (about 12"), 52.5 mm pitch, 82 links, wide guide lugs
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.
Tread choice for the Case CX31
Size gets the track on the machine; tread decides how it works and how long it lasts. What we stock for this one:
Staggered Block — mixed dirt and gravel. Block stability with better cleanout than a straight block
Undercarriage parts for the Case CX31
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:
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.
