Meguin Transmission Hydraulic Oil TO-4 SAE 50 is a high-performance transmission hydraulic oil for construction machinery, specially developed to meet the highest current requirements and those expected in the future. It guarantees excellent compatibility of transmission components and friction linings where engine oils are overtaxed. The optimum formulation ensures higher transmission performance and longer clutch life thanks to specifically adjusted friction coefficient characteristics and excellent wear protection. megol Getriebe-Hydraulikoel TO-4 has been specially developed for use in highly stressed transmission components of construction machinery, such as powershift transmissions, side drives, axle drives and wet brakes. Chatter in wet brakes is eliminated.
