Air Injection Filter: Service and Repair
REMOVAL
Removing Centrifugal Filter Fan
A damaged filter fan may be removed by inserting needle nose pliers between the plastic filter fins and breaking fan from hub. Care should be
taken to prevent fragments from entering the air intake hole. Do not insert screwdriver blade between pump and filter. It is seldom possible to
remove the fan without destroying it. Do not attempt to remove the metal drive hub.
INSTALLATION
Installing Centrifugal Filter Fan
Install the new filter fan by drawing it into position, using the belt pulley and pulley mounting screws. Draw the fan down evenly by alternately
tightening the screws. Be sure that the outer edge of the fan slips into the housing. A slight amount of interference with the housing bore is normal.
Do not attempt to install a fan by hammering or pressing it on. After a new fan is installed, it may squeal until the sealing lip of the outside
diameter wears in. This may require 32-48 km (20-30 miles) of operation.
