Average weight ... 23.0 kg (50.70 lb)Number of cylinders ... 2Bore size ... 88.0 mm (3.465 inch)Stroke ... 50.0 mm (1.968 inch)Displacement at 1250 rpm ... 0.764 CMM (27 CFM)Maximum recommended rpm ... 3000 RPMRequired horsepower at 1800 rpm Loaded ... 7.5 hp Unloaded ... 0.9 hpMaximum sustained discharge line pressure ... 1034 kPa (150 psi)Maximum transient discharge line pressure ... 1241 kPa (180 psi)Relief valve to be installed in the cylinder head of the air compressor ... 1724 kPa (250 psi)Line insulation: For low duty cycle applications, the air dryer inlet fitting and up to 0.91 m (3.0 ft) of the line toward the air compressor should be insulated, if the line is more than 2.75 m (9.0 ft) long. For example: if the discharge line is 3.05 m (10.0 ft) long, insulate the air dryer inlet fitting and the last 0.30 m (1.0 ft) of the discharge line. If the discharge line is 2.75 m (9.0 ft), insulate the air dryer inlet fitting and the last 0.91 m (3.0 ft) of the discharge line.Discharge line slope: The line from the air compressor discharge port to the air dryer inlet fitting should slope downward from the air compressor to the air dryer inlet fitting. The line should not have any droops that exceed one half of the diameter of the discharge line.Crankshaft nut for drive gear torque: Tighten the crankshaft nut to a torque of 169 N m (125 lb ft). Tap the gear with a mallet in order to seat the gear on the taper of the crankshaft. Tighten the nut again to a torque of 169 N m (125 lb ft).Coolant flow Minimum coolant flow at 700 rpm ... 1.9 L/min (0.50 US gpm) Minimum coolant flow at 3000 rpm ... 9.5 L/min (2.51 US gpm) Maximum coolant temperature ... 127 °C (260 °F) Minimum size of coolant line ... 9.7 mm (0.38 inch)Maximum inlet air temperature ... 121 °C (250 °F)Maximum discharge air temperature ... 204 °C (400 °F)Minimum ambient temperature ... -40 °C (-40 °F)Maximum ambient temperature ... 121 °C (250 °F)Maximum air dryer inlet temperature ... 71 °C (160 °F)Minimum air dryer inlet temperature ... 7 °C (45 °F)Note: Low air dryer inlet temperatures should be avoided in order to minimize the risk of "freeze-up" upstream of the air dryer.Heat shield: Required if the air compressor is located within 76mm (3.0 inches) of an exhaust pipe or a turbocharger. ... Lubrication Minimum oil pressure at idle speed ... 103 kPa (15 psi) Minimum oil pressure at maximum speed ... 103 kPa (15 psi) Minimum size of oil supply line ... 4.76 mm (0.188 inch) Maximum oil temperature (measured at oil inlet) ... 121 °C (250 °F)Minimum inside diameter of air inlet line ... 25.4 mm (1.00 inch)Minimum inside diameter of air discharge line ... 16.69 mm (0.650 inch)Minimum inside diameter of unloader line ... 4.76 mm (0.188 inch)Minimum governor "cut-in" pressure ... 758 kPa (110 psi)Air pressure to open synchronization valve ...
