Hemofluid CAT TO-4 is a range of universal transmission oils engineered to meet the demanding quality levels required by Caterpillar and Allison equipment. These oils are specifically recommended for construction, mining, and agricultural machinery including bulldozers, excavators, wheel loaders, tractors, and similar heavy equipment from European, American, and Asian manufacturers.

The TO-4 formulation is designed for multi-system lubrication and power transmission across all major drivetrain components in heavy equipment. These oils provide effective lubrication for hydraulic systems, transmissions and differentials, cardan shafts, drive axles, steering assemblies, side reducers, bevel gears, torque amplifiers, and wet brakes — serving as a comprehensive drivetrain fluid for the entire machine.

Hemofluid CAT TO-4 oils feature optimized friction characteristics that are critical for proper wet brake operation in heavy equipment. Consistent brake friction ensures safe, predictable stopping performance even under the heavy loads and demanding conditions typical of construction sites, quarries, and mining operations. The oils also deliver reliable clutch engagement and smooth transmission shifting.

Additional benefits include excellent anti-wear protection for heavily loaded gears and bearings, strong corrosion inhibition for internal metal surfaces, good thermal and oxidative stability for extended service intervals, and effective foam suppression. It is important to note that these oils are designed exclusively for drivetrain applications and must never be used as engine oils. Hemofluid CAT TO-4 is a proven, reliable transmission fluid for operators of heavy construction, mining, and agricultural equipment who need a single product meeting the industry's most demanding drivetrain specifications.
