Head Fitting Type: O Ring Type 3/4"x7/8"; Tube-O Type 1"-14 or Pad Type 4. Clutch Voltage: Determine if 12 or 24 Volt System 5. Clutch Type: Determine if Single, Double or Multi Groove Clutch Pulley 6. Clutch Diameter: Measure the Diameter of the Pulley 7. Clutch Connection: Single or Double Wire, Bullet, MetriPack or WeatherPak 8. Clutch A-B Distance: For proper belt alignment, accurately measure the A-B Distance 9. Mounting Type: Ear Mount or Direct Mount (crossbolt or tangential) Type10. Service Valve: Choose the correct service valve using that section of this catalogSANDEN COMPRESSORSS electing The Correct Sanden CompressorThere are several different ways to choose the correct Sanden replacement - refer to the application section looking up application by Make, Year and Model and select the compressorneeded.
