Ok, so I'm trying to keep the front wheels of my late dad's old tractor from falling off. So, I purchased two new aftermarket spindles (about $20 each!?), and a wheel bearing kit that matches the original Timken numbers that are on the original bearings and races. The bearings would NOT go onto the new spindle. They would go on the old spindles and pictured below is what I'm confused about. There's a gap that wasn't there before. Granted, there was some scoring from the hub onto the spindle, which is why I ordered the new spindles in the first place. Is this gap normal? And why would the bearings not go onto the new spindles which look identical to the original spindles, except for the scoring of course. Also, I purchase the 2 spindles from 2 different sources. Strange that the new bearings with the correct numbers would go on the old spindles, but no way were they going on the new ones.
