Bearings
I bought a puller and installer fairly early on in my business, but I knew repairmen who would use an old spin shaft to pound out the bushings, and the right size pipe to pound in the new ones. I decided that the right tools were better than the caveman approach. I would use a wire brush cone on a drill extension shaft and clean out the tube that holds the bushings and seals. My 3/8" drill had plenty of power for this. I never tried this, but one man told me to put the bronze bushings in the freezer over night before installing them, and they would go in a lot easier. I had a friend who would wash her throw rugs often in her Kenmore. She said that her machine was "a little noisy". I looked at it, and the bushings were gone! The spin shaft was ground down to 1/2 the origional thickness at the top. I tried to put new bushings in, and the top one rattled down the center tube and fell on the floor under the machine. I got her another machine for less money than it would have cost to fix her old one.
