Key Technical Advantages:
- Reinforced Core: Forged steel inserts are precisely embedded to prevent de-tracking.
- Abrasion Resistance: The rubber compound is enriched to resist cuts from sharp edges like rubble and rocks.
- Operator Comfort: Optimized tread pattern ensures good traction while limiting vibrations.

Service Tip: When installing a new track, always inspect the undercarriage. Running a new track on a worn
drive sprocket or damaged idler will drastically shorten the track's lifespan.
Frequently Asked Questions (FAQ)
Does the link count (76) matter?
Yes, it is crucial! In this machine class (e.g., Volvo ECR88 or Kobelco SK75), versions with both 76 and 78 links exist. A difference of 2 links may make it impossible to tension the track. Please count the links on your old track before purchasing.
What is the pitch of this track?
This track has an 81.5 mm pitch. It is standard for many Japanese machines (Hitachi, Komatsu). It does not fit machines requiring an 81 mm or 83.5 mm pitch – the difference is visually small but critical for the sprocket.
