Replacement rubber tracks for the Volvo EC35C mini excavator in 300x52.5Wx84 — 300 mm wide, 52.5 mm pitch, 84 links. Built for digging, trenching, backfill and tight-quarters work, with free freight to the lower 48.
What the numbers mean on a Volvo EC35C
- 300x52.5Wx84 — 300 mm tread width (about 12"), 52.5 mm pitch, 84 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 Volvo EC35C
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 Volvo EC35C
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:
- Carrier roller — 1180-9221
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
Track size follows undercarriage geometry, not brand, so 300x52.5Wx84 shows up on machines from several makers. If you run any of these alongside the Volvo EC35C, it is the same belt:
- CAT 303.5
- CAT 303CR
- CAT 303E CR

- CAT MM35T
- Case CK36
- Ditch Witch MX35

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.
