I am in the process of overhauling a very old condensate water pump in a cooling tower circuit. I don't even know yet what brand of pump it is. What I do know is that the shaft is supported by two bearing inserts located at each end of the casing (no ball bearings). I was able to remove the shaft by using a hydraulic shop press, but so far cannot find a way to get the bearing inserts out of their holes. I do not want to pry on them or force them out with a chisel because I want them intact in order to get an exact replacement. Is there any factory or home made tool idea that can be used in this situation ? By the way, they are about 1.5 inches I.D. and their thickness is about 1/8 of an inch.
