( 1 ) All Post-Turn Seals are made from the new material.An improved lubricant for all link assemblies and track groups is now used. The 75W-140 lubricant is a synthetic gear oil. This lubricant improves the wear characteristics of the contact surfaces of the internal joints throughout the life of the track. This lubricant provides improved wear characteristics for the seal lips. Wear characteristics are also improved for the faces of the bushing ends at the contact point between the seal lip and the bushing. The former lubricant was an 80W-90 mineral oil.
