The inner race on this inner duplex bearing remains on the shaft when the bearing is pulled. Re-
move this inner race by applying heat. Do this away from the pump site.
WARNING:
The pump may handle hazardous and/or toxic liquids. Trapped or undrained liquid can cause
explosions when heat is applied. Never apply heat at the pump site for this reason. Heat can
also distort machined surfaces.
