The Komatsu PC30MR 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 Komatsu PC30MR
- 300x52.5Nx84 — 300 mm (12") wide, 52.5 mm pitch, 84 links, narrow guide lugs
- 320x54x82 — 320 mm (13") wide, 54 mm pitch, 82 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.

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 Komatsu PC30MR, it is the same belt:
- Bobcat E35
- Bobcat E35C
- Bobcat E35Z
- Bobcat E35i
- Ditch Witch MX35
- Doosan DX30
- Doosan DX30Z
- Hanix H36B
- Hanix H36C
- Hanix H36CR
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.
