Final Drive Lubricants

Schaeffer Simplex Supreme #315 Final Drive Lubricants

Schaeffer #315 Simplex Supreme is a universal extreme pressure semi-synthetic torque converter fluid designed for use in most farm and industrial tractors. Simplex Supreme meets and exceeds the service make-up and refill needs of the transmissions, differentials, final drives, hydraulic and power steering systems and wet brake systems of such equipment, especially those employing a common reservoir or sump.

Simplex Supreme is blended from the finest solvent refined hydro-finished high viscosity index 100% paraffin base oils and polyalphaolefin (PAO) synthetic fluids available. This unique combination provides the Simplex Supreme with the following advantages:

  1. Very good to excellent low temperature fluidity in order to provide easier cold weather starting and better wear protection during low temperature conditions.
  2. Superior Oxidation Stability - Any oil as it is increasingly exposed to high temperature operation undergoes the process of oxidation. This results in the oils thickening and buildup of acidic components.
  3. Excellent Resistance to Thermal Degradation.
  4. High Viscosity Index - This results in a minimum change in viscosity. The adequate viscosity for proper lubrication of the tractor's hydraulic, transmission, final drive and wet brake system is provided regardless of temperature change.
  5. Excellent Film Strength - This results in increased wear protection.
  6. Superior Operating Temperature Reduction - This unique combination of PAO and 100% paraffin base oils have better specific heat values (less heat is absorbed) and better thermal conductivity that conventional oils.
  7. Compatibility With All Types of Seals and Coatings.

Performance Qualities:

  1. Exceptional anti-wear and extreme pressure properties needed to prevent gear and pump wear, especially under heavily loaded conditions.
  2. Stable and controlled friction performance with various metallic and non-metallic friction materials. This results in the elimination of problems with excessive noise, weak bindings and embrittlement of elastomeric materials.
  3. Chatter-free power transfer for wet brakes.
  4. The proper extreme frictional characteristics needed to assure the proper and decisive functioning of power take off clutches in a wet brake system.
  5. Superior protection against rust and corrosion.
  6. Excellent water tolerance.
  7. Enhance filterability which minimizes filter blocking due to water contamination.
  8. Excellent anti-foaming and air release properties, to ensure smooth, efficient operation and proper lubrication of all components.
  9. Improved and increased operating efficiency and durability.
  10. Longer fluid life.
  11. Reduced system maintenance.
  12. Longer equipment life.
