Hub Shaft Problem? (what the hub!)
My son bought a used bike yesterday and told me that it's great, but the front wheel is kinda rough.
So I open up the hub, the bearings are near greaseless and the cones are pitted to death, but the cups are surprisingly fine.
Here's my issue. In cleaning the inside of the hub, I notice that the edges of the hub shaft (I don't know what it's officially called, the hole in the center of the hub in which the axle sits) are sharp and slightly protruding (by maybe 1 to 1.5mm) into the area in which the bearings sit, on both sides. I'm not sure if these protrusions are actually coming into contact with the bearings, it seems to me that the bearing might actually be going around them without touching.
I just wanted to know if anyone has had any experience with what I'm describing, and if so, can the wheel be saved (filing down the protrusions?), before I waste my time going to the bike shop to buy some cones and bearings, put it all together and then find out the hub is no good.
It would be a shame to have to toss the wheel, because it was built very well and the rim still has a lot of life left in it.
As always, your input is appreciated.
