Newbie: axle replacement [PICS]

hi,

I'm getting into bicycle-DIY and I'm having trouble replacing a rear axle on my old mountain bike.

After removing the old axle I noticed, on the cassette side of the hub, a conical washer and 9 free ball bearings inside the hub.

The thing is, after removing the axle, the conical washer and ball bearings went all over the place and I don't know their original order.

This is a pic of what the washer looks like without grease.

Pics of my hub:



So does the washer go above or below the balls?

Thanks!

Your axle should basically come together like this:http://www.sheldonbrown.com/gloss_cn-z.html#cone

Yup, the order of the washer and nuts on the axle is fine.

It's the order of the conical washer and bearings inside the hub that I'm confused about.

Maybe this will help. Servicing a Shimano freehub video.

Starting from the hub shell you should have:
-the "cup", bearing race press-fit to the hub shell, usually not removed/removable
-the bearing balls
-the cone, often incl dust shield
-on the drive side, spacer(s). On the non drive side usually nothing.
-locknut, preferably knurled/serrated on the outside

Sometimes, washers gets added underneath the locknut to adjust either the spacing, or the position of the wheel in the frame. Less particular mechanics might add them outside the locknut to save themselves one step of the work process.
If the locknut is smooth, a knurled/serrated washer is sometimes placed outside the locknut to help the wheel stay in alignment in the frame when pedalling. Shouldn't be a conical one though.

Thanks dabac and TibikeGuy, though I'm still stuck.

Here's a few images of my cassette-facing hub:

Not all the bearings are in the hub and as you can see there's a conical washer that I don't know what to do with.

That's not a washer, it's a dust cap, and it should be a press fit into the hub with the curve facing outward. Given the condition of the balls and grease it's important that you inspect for pitting and uneven wear on both cones and cups.

Don't tell me what "should" be - either it is, it isn't, or do something about it.

If you think I'm being blunt take it as a compliment - if I thought you were too weak to handle the truth or a strong opinion I would not bother.

Please respect others by taking the time to post clearly so we can answer quickly. All lowercase and multiple typos makes for a hard read. Thanks!

That is not a cassette freehub, but a rear hub that uses a freewheel. Wipe off the excess grease and inspect the inside surface (the cup) for uneven wear and cracks. Also check the sloping piece on the axle(the cone). If both is well worn, then toss it and get a new hub. It might be cheaper to get a new wheelset or get one on the 2nd hand market. Most bike shops have some old wheels that are lying around.
