HELP!!!!

[Joe24]

My rear hub on my fixed is not good
I took it out in the rain on thursday, then went on it to go to work on saturday. It clunked abit but i didnt think too much about it.
Ive gone on it today and its clunking worse. I limped home, having to tighten up the bolt on the hub every so often to stop the wheel wobbling
Heres a pic of it after i took the nuts off from one side

On one side, the bearings show, on the other side they dont, so the axle isnt sitting straight,
Since i had the Langdale frame when i built it up, theres always been a slack tight spot, which ive always had on all of my fixed bikes.
Ive got a feeling it could of been this causing that slack tight chainess.

So what can i do? Is the hub ****ed? Do i just need to take the axle and bearings out and put new ones in? They are cartridge bearings in that by the way, its a System ex fixed/fixed hub.

HELP!!!!

Isn't this missing a dustcap joe....?

Clunking sound and wobbly wheel sounds like the bearings are knackered. Most likely will have happened on the drive side. It is easy enough to knock the old bearings out (put a nut on the end of the axle and tap gently.) Replacement bearings are 6000z or they are on my Sys Ex hub.

In cartridge bearings, there are few enough balls that if they are all moved towards one side the inner race can be moved to one side enough to allow the balls to be put in through the wider gap. The balls are then distributed around the bearing to centralise the inner race and a cage is added to stop them moving back together.
It looks like this cage has gone missing, taking any seal/shield with it.

BEFORE REMOVING THE BEARING, distribute the balls evenly around the bearing and poke something in the gaps to keep them there - eg the ends of cocktail skewers or matches.
If you don't the cartridge will very likely come apart and you'll be left with just the outer race in the hub shell. This will be considerably more difficult to remove than a reasonably intact cartridge.

I took the dust cap off, it was maky and nearly coming off for some reason so when i was looking at the wheel i poped it off to see what was up.
The dustcap isnt in that good of a condition, the other side is fine, but that side has only been used when ive done TTs.
So to get the bearings out, i just put a nut on the side i want to take the bearings out, or on the other side and tap that to get them out?
Or do i distribute the bearings around the cartridge then take the whole cartridge out?
Im lost, sorry

 

[Bokonon]

Nut on the side you _don't_ want to take the bearing out of, and tap the axle toward the bearing you want out - as the axle pops out the other end, it takes the bearing with it. The purpose of the nut is that it takes any damage resultant from the tapping.

What andrew was getting at is that if the bearing is very warn then you are likely to remove the centre race from the bearing with the outer race left in place. I think this is unlikely if you have only just started having trouble. If it does happen, it shouldn't be too difficult to get the race out.

It did get pretty bad, and there was a bad griding noise just before i stopped and got the Team Joe car out(i got mum to come pick me up)

Could it be that this is a track fixed hub as opposed to a road fixed, so the bearings will not be sealed and suffer from exposure to the elements?

No, they are sealed, i took the seal off, and it has the seal on the other side.

dunno if it's any help to you joe but you might be able to get a new wheel for cheaper than you think - I got the back wheel on my fixed for £20 from zone cycles in newark, second hand, but it's brilliant - maillard hub (french) but standard fixed-fixed, double thread configuration.
Might be worth a try see if he's got any more?
He's a pretty sound guy in there, I got another front wheel for my winter bike in there as well, he charged me £32 for that, dunno why, maybe it's newer/more likely to sell? You just seem to be able to go in the back, ask for a generic wheel and he goes in the back and 'produces' one. No element of choice between different models, but that's 2 out of 2 times i've needed a cheap wheel and he has not failed to 'produce' a suitable one
stop building more fixeds and concentrate on the one(s)you've got!

Hmmmm, i might do this and have one in the shed as spare
Ill give them a call tomorrow.
That wheel is pretty good though, its a strong wheel, just abit disapointing the bearings have gone already

Cheers Bonj Ill give them a call tomorrow.
Can i afford a spare wheel for my fixeds? No.
Do i need one? Yes

can you afford NOT to?

Nope, ill be losing out on my training.

Not that i havent got other bikes to train on but................
