35. The supercharger must be filled with oil prior to use. This supercharger is shipped without oil inside. The oil is in a
separate bottle supplied with your kit and is prefilled to the exact oil amount.
CAUTION! Severe damage to the compressor will occur if you overfill the supercharger rear gear case.
 Make sure the SC is sitting on a flat surface.
 Remove -6AN allen plug (1/4” allen wrench) and fill SC with WHIPPLE SC OIL ONLY!!
 Fill to the middle of the sight glass. Tip from side to side then with the SC flat again, check oil level again,
add if necessary. Whipple kits are supplied with pre-measured oil bottles, therefore, on all new installs
NOTE: The W175FF compressor takes a maximum of 8 fl/oz and a minimum of 7.5 fl/oz. Failure to fill
properly will result in catastrophic damage.
 Reinstall -6AN allen plug.
 NOTE: After running the SC, the oil level will lower due to oil filling the bearings. The proper level while not
running should be between the bottom of the sight glass and the middle and will vary when running and not
running.
 Change SC oil every 100,000 miles and only use WHIPPLE SC OIL ONLY!!
