Oscar HDM TFX FDAO 60

Oscar HDM TFX FDAO 60 is a premium, heavy duty, SAE 60 gear lubricant specifically designed for use in final drives and axles of modern Caterpillar off-road equipment operating in severe service, where fluids meeting Cat FD-1 are recommended.

APPLICATION

• Final drives, axles, differentials and front wheels of Caterpillar equipment where FD-1 performance fluid is specified. 

• Caterpillar heavy-duty off-highway haul trucks.

• Caterpillar wheeled and track-type tractors. 

• Unlike conventional TO-4 type fluids, it is generally notsuitable for powershift transmissions or for oil immersed brakes or clutches, unless recommended by Caterpillar, due to different frictional characteristics. Caltex Torque Fluid 4N4 series should be recommended for Caterpillar powershift transmissions, hydraulics and wet brake applications requiring TO-4 type lubricants

PROPERTIES

  • Extends equipment life in severe service: Advanced additive system minimizes wear in heavily loaded gears and bearings by forming a strong protective layer on metal surfaces under extreme service conditions.
  • Prolongs oil life: Extremely high thermal and oxidation stability protects against oil thickening and deposit formation and extends oil drain interval by up to 100% compared to conventional TO-4 type fluids. 
  • Minimizes unscheduled maintenance: Effective rust and corrosion inhibitors protect final drive components. Good viscosity characteristics at low temperatures ensure rapid oil circulation on start-up, preventing damaging wear.
  • Trouble-free operation: Fully compatible with all seal materials and with TO-4 type oils, eliminating risk of operational problems when converting to new lubricant.
