Fluid Fill Angle 0° 50° 0° Recommended Fluids ➀ ISO Viscosity Grade, Petroleum Oils (R & O) ................................................................. 46 ISO Viscosity Grade, Synthetic Oils ............................................................................... 32 Viscosity at 104°F(40°C) — 46 cSt (215 SSU) Viscosity Index — Equal to or greater than 95. HIGH LEVEL OF FILL Pour Point — Must be 5°F (3°C) lower than minimum starting temperature. 100° LOW LEVEL OF FILL Fluid couplings are shipped without fluid. Fluid is added during installation. The installer adds fluid, obtained locally, and that meets “Recommended Fluids” specifications listed on this page. When application data (horsepower, rpm, start factor) is provided, the fluid coupling will include an orange sticker with fill angle (degrees), and approximate fill quantity (fluid ounces). If no orange sticker is present, a fill angle may be obtained from the Quick Selection tables in this catalog (pages 14-19). Using fill angle as a starting point, approximate fill quantity (fluid ounces) may be obtained from the table below. Fluid couplings include an angle finder (P/N 1224653) and installation instructions. Remove the fill plug, place the angle finder on the flat boss at the fill plug location, and rotate the coupling to the specified fill angle (degrees from vertical). With the coupling in this position, add fluid until it reaches the lip of the fill hole. As shown above, a low fill angle (example is 50°) corresponds to a high level of fill. A high fill angle (example is 100°) corresponds to a low level of fill. The level of fill in the coupling determines the start factor, percent slip, starting torque, stall torque, ... essentially all performance characteristics of the coupling. After installation and operation, fine-tuning of the fill level may be necessary, based on load readings or other site variables. In general, increasing the fill level (decreasing the fill angle) increases start factor/start torque/stall torque, shortens time required to accelerate the load to operating speed, and reduces percent slip. Reducing the fill level (increasing the fill angle) decreases start factor/start torque/stall torque, increases time required to accelerate the load to operating speed, and increases percent slip. Convert Fluid Ounces to Weight (lb) There are 128 Fluid Ounces per Gallon Weight (lb) = Fluid oz x 0.0648 x specific gravity of the fluid Example: Size 1480HFN @ 70 degree fill angle (See table below) Weight = 413 fluid oz x 0.0648 x 0.87 = 23.3 lb of fluid Flash Point — 400°F (204°C) when using 140°C and/or 180°C fusible plugs. Flash Point — 425°F (218°C) when using 200°C fusible plugs at both fill and drain holes.
