Air Pump
- Servicing of air pump is limited to replacement of centrifugal fan filter or entire pump. Do not clamp pump in a vise or use a hammer on pump housing.
- To replace centrifugal filter, insert needle nose pliers between filter fins and break fan from hub. Install new fan, using pulley and bolts to draw fan down evenly.
NOTE:
Fan might have a slight squeal until sealing lip is worn in. Air injection system is not completely noiseless. Normal noise increases in pitch as engine speed increases.
CAUTION:
If the engine compartment is to be cleaned with steam or high pressure liquids, fan filter should be masked off to prevent liquid from entering air pump.
