The Y symbol designates a track designed for Yanmar equipment. It is an asymmetric design with external guiding, required for models where the undercarriage is positioned close to the frame. Many 300 mm wide tracks have a standard 52.5 mm pitch. This track has a specific 55.5 mm pitch. Installing the wrong pitch will cause the track to "skip" on the sprocket and destroy it quickly. Please make sure your old track has the same pitch. What does the Y symbol mean?
Why is the 55.5 mm pitch important?
