5.3.2 Solids Discharge Bushings
The discharge bushings should be replaced before wear is allowed on the bowl. To
remove discharge bushings use a soft drift and a hammer to tap out as shown in
Figure 29.
Replace bushings in pairs only. Replace the defective bushings and the one opposite
it.
To install discharge bushings, clean outer surface of new bushings and inner surface
seats of the bowl. Apply a thin layer of loctite 270 to the surface of the discharge
bushings. Insert bushings into the seat and turn until the loctite is uniformly
distributed. Press bushing tightly into place. Handling strength is obtained after 20
minutes and maximum strength after 3 hours. Refer to Figure 30 for installation.
