Place a small amount of grease in the slot at the tapered end of the Crankshaft (49) and insert the Woodruff Key (50) into the slot. Figure A: Pump Pulley Assembly Installation 2. Use a motor with the appropriate size pulley to achieve the needed Pump RPM. To calculate the motor and motor pulley needed to power the pump, multiply the Pump Pulley diameter (14.5") times the pump working RPM (1050) which equals 15,225, then divide by the motor RPM. This will determine the motor pulley diameter (in inches) needed to run the unit. For example: To calculate the pulley diameter needed for a 1725 RPM motor, multiply 14.5 by 1050, then divide by 1725, which equals a motor pulley size of 8.8 inches. Use the pulley size closest to this figure. 15,225 1725 Item 67698 = 8.8" 15,225 (14.5" Pump Pulley Dia. x 1050 Pump RPM) Motor RPM = Motor Pulley Dia. Maintenance 1. Place the Air Compressor Pump on the mounting surface at the same level as the 5 HP motor used to drive it. Pump positioning must incorporate easy access to the Oil Drain Plug (36). Motor Pulley Figure B: Calculation for Motor Pulley 3. The Pump Pulley (58) must be in perfect alignment with the motor pulley (not included). Misalignment between the Motor and the Pump can cause damage to both the motor and the compressor pump. Use a straight edge, such as a yardstick, to check and adjust alignment as needed. Note: Ensure the Pump Pulley is installed for counterclockwise rotation when facing the pulley side of the Pump. 4. Verify that the Pump Pulley turns freely where it overhangs the mounting surface. 5. Place two V-groove belts (not included) over the Pump Pulley and the motor pulley.
