INSTALLATION
NOTE : Depending on your level of expertise, you may wish to have a qualified technician perform this
installation.
NOTICE : Avoid damage to the Air Compressor Pump and other equipment. The Compressor Pump
mounting platform should be flat, level, and strong enough to support the combined weight of the Pump,
electric motor or engine, and related hardware and equipment. It must also be capable of withstanding the
vibration and tension of the drive belt.
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).
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.
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.
6. Pull the Compressor Pump until properly aligned, and the belts are tight. Recheck the motor pulley,
V-belts, and Pump Pulley alignment.
7. Use mounting holes in the Compressor Pump base as a template to mark the spots where four holes will
be drilled in the mounting surface.
8. Move the Compressor Pump aside and drill four 3/8” diameter holes in the mounting surface.
