What the numbers mean on a Komatsu PC75

• 450x76x80 — 450 mm tread width (about 18"), 76 mm pitch, 80 links

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 Komatsu PC75

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

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 450x76x80 shows up on machines from several makers. If you run any of these alongside the Komatsu PC75, it is the same belt:

• Gehl 802
• Gehl 803
• Komatsu PC75-1
• Komatsu PC75R
• Komatsu PC75R-2
• Komatsu PC75R-8
• Mustang ME8003

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.
