The Yanmar VIO35-3B takes a 300 mm track, but it was built with more than one pitch — 52.5 and 55.5 mm. Same width, different drive-lug spacing, and they do not swap. Check the old track or the sprocket before ordering. Free freight to the lower 48, 24-month warranty.
Yanmar VIO35-3B track options
- 300x55.5x82 — 300 mm (12") wide, 55.5 mm pitch, 82 links
- 300x52.5Wx82 — 300 mm (12") wide, 52.5 mm pitch, 82 links, wide guide lugs
Same tread width on all of them — what changes is pitch and link count, which is set by the sprocket and roller frame. Read the numbers off the inside of the old track rather than going by model year; these were built across more than one undercarriage spec.
Tread choice for the Yanmar VIO35-3B
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

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 one of these sizes shows up on machines from several makers. If you run any of these alongside the Yanmar VIO35-3B, it is the same belt:
- Airman HM30SGZ
- CAT 302.7DCR
- Case 31
- Case CK31
- Case CX31
- Case CX31B
- Kobelco SK024
- Kobelco SK027
- Kobelco SK027-1
- Kobelco SK030
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.
