Greyhound Transmission TO-4 SAE 50 5L
Greyhound Transmission TO-4 SAE 50 is a specialist powertrain lubricant engineered for Caterpillar and yellow-equipment differentials and final drives. Specifically, this 5L SAE 50 grade is formulated for heavily loaded gears and bearings where robust film strength is the main consideration.
Because heavy earthmoving machines demand precise frictional control, this Transmission TO-4 SAE 50 oil delivers balanced static and dynamic friction. Moreover, it meets Caterpillar’s latest drive-train requirements, so operators gain durable performance and maximum power transfer throughout the service interval.
Heavy-Load Final-Drive Protection
For example, SAE 50 and 60 grades suit differentials and final drives, while SAE 10W and 30 cover transmissions and hydraulics. In addition, superior shear stability protects heavily loaded gears and bearings. As a result, equipment productivity rises and downtime falls. Therefore, fleets running construction plant gain longer component life.
Key Features:
- Improved clutch life: up to 45% over TO-2 fluids
- Balanced static/dynamic friction for durability and power transfer
- Outstanding shear stability and viscosity retention reduce wear
- Excellent thermal, oxidation, sludge and corrosion protection
- Increased film strength protects heavily loaded gears and bearings
- Effective in differentials and final drives without frictional materials
Technical Specifications:
