The Bobcat 430D is cataloged in more than one track width — 300 / 320 mm. Pick the width your undercarriage is actually set up for, then choose tread for the ground you work. Free freight to the lower 48 on every track, 24-month warranty.
Which width fits your Bobcat 430D
- 320x54x90 — 320 mm (13") wide, 54 mm pitch, 90 links
- 300x52.5x92 — 300 mm (12") wide, 52.5 mm pitch, 92 links
These are not interchangeable by preference — the width your machine takes is set by the roller frame and sprocket it left the factory with. Wider tread floats better on soft ground and spreads ground pressure; narrower runs cheaper, turns easier and clears tight spots. Measure the existing track across the tread face before you order.
Tread choice for the Bobcat 430D
Size gets the track on the machine; tread decides how it works and how long it lasts. What we stock for this one:
- Directional — digging, trenching and slope work. The standard excavator tread
Undercarriage parts for the Bobcat 430D
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:
- Front idler — 7199074
- Bottom roller — 7013575
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
