38.6mm Inner Diameter Thrust Disc

Service component for the transmission planetary group. It has 3 grooves with equally spaced in both sides. It can resistant to fuels and lubricants.caterpiller plastic disc have better reliability and longer durability. Cat friction discs are designed to work within the transmission system to absorb the high power and energy during shifting.Caterpillar friction disc use better materials and more mature processes, so caterpiller friction disc have better reliability and longer durability, which can reduce machine downtime.
