Re: Lets talk leakless water pumps!
Approximately 3 years ago I rebuilt a number of water pumps for myself and other members of our club. I used stainless steel shafts with modern lip sealsin front and in the rear bushing. I have about 3,500 miles on my pump and this year my pump started to leak bad. I had no problems prior. I disassembled the pump and found that each of the seals had worn grooves into the shaft. I had another (non-stainless) steel shaft as well as seals, so I just rebuilt it, hoping that it will last longer than the stainless shaft. I am going to have a shaft made of medium carbon steel and surface harden the area of seal contact to prevent wear from the seal. Don/WI
