Common Use Case or Symptoms: Use when the drive sprocket teeth are worn, cracked, or broken — worn sprocket teeth on the Kubota K008-3 cause accelerated rubber track wear, track slipping or jumping, and reduced travel performance. Sprockets should be inspected whenever rubber tracks are replaced and changed proactively before wear damages the track.
