After installing my wheel assemblies - I was spinning the wheels to get the appropriate drag from the tapered roller bearings. I noticed that my wheel was exhibiting a runout condition. I measured .085 inches at the wheel outer edge and .067 inches at the outer edge of the brake disc. My friend suggested that perhaps the bearing races had not been fully seated - causing this runout condition. So, I dis-assembled the wheels and took them to an arbor press. Sure enough, I was able to push each race in an additional .080 - .085 inches. After re-assembling the wheel/tire assemblies and installing them on the axles - all of the runout condition was gone.

This is an easy extra step to do before assembling the wheels. I purchased a few fender washers from Rural King (cost of 10 cents each) with an outside diameter of 1.75 inches. It was a perfect match to the bearing race diameter.
