Disc 5W5690 works in a pack with steel separator plates. When replacing friction discs, it is recommended to verify the condition of the separators and change the axle oil to fresh, CAT-specification compliant.
Wear of the rear axle clutch discs leads to drive slippage, loss of power to the wheels, and oil overheating. Prolonged operation with worn discs can cause damage to the clutch basket and costly axle repair.
The disc is responsible for transmitting drive to the rear axle and traction control.
