repacking front hub with grease.. damage to cones.
Postby janus77 » Wed Jun 11, 2008 11:19 pm
So.... after finding the 3 or 4 bearings that popped out before I realised what I was doing, i've chucked them in a little container of kero to clean them off. I don't have any degreaser, so have just cleaned out the cups inside the hub with a bit of kitchen paper.
The hub was running VERY roughly when rolling it by hand before pulling it apart, there was quite a bit of crap in them from all my rain riding.
The main issue I've found is that the cones on the hub axle are damaged, there is some rough pitting, either dirt in there, or maybe they were done up too tight? Anyway they obviously need to be replaced.
Is it possible to get these easily from bike shops?
I have to go and collect my Kenevans tomorrow morning anyway, so will check with them.
Is it much more difficult to repack rear hubs? Should I buy a few spare cones in case of this, are they expensive?
Cheers loving having grease on me!

The back was a similar procedure to the front, but while cleaning the back and repacking the bearings, I removed the cassette and gave it a good clean.
Enjoy your new toolset......next it will be the bottom bracket.

I had the good fortune to break a spoke on my Ventos on Monday, so I've put another bike on the road for a few days - which meant that I spent last night servicing the hubs on some Shimano WH 560 wheels for it. The front was no problem, but the rear (which I knew needed replacement cones / bearings ) is still rough. The drive side cup in the hub has a 'discoloured' track worn around it, so I expect that it needs to be replaced as well. Fortunately, it appears that it screws into the cassette body, so it should be replaceable. Oh well, more fun with gready fingers.
ps. I stuck up for the WH R560's on another thread, that was about the spoke pattern (and the number of spokes). I'm not going to stick up for them any more - even though they've been fine to ride and they look pretty. I've had to replace the cones in both front and rear wheels now, while the old 105-hubbed Mavics that came with the girlie bike still spin better and I haven't had to touch them.

Asked him if i might have damaged them because I take the front wheel off sometimes to put it in my car, if I did the quick release up too tight, but he didn't seem to think i could have damaged it because of that... anyone have any comments on this? Sheldon Brown's website says you have to be careful about doing the quick release up wiht the cup/cone hubs, it can be too tight?

Lucky I got a spare this morning from LBS near home when I picked up my other ride, they sold me an axle, the cones are shallower that the original ones in the hub, but there were some spacers in there too, so hopefully it will fit.
bought a big thing of citrus degreaser and some lithium bike grease (any good?)too. All set!
can you buy boxes of ball bearings? (front and back are different size right?)

There's probably a Shimano stand in your lbs with pre-packed sets that are only a few (well, 'coz it's Shimano, a big few) bucks each.
Yes, you need different bearings for the front and back.

amazing that with so many wrenches, this tool kit does not include one that fits the nuts on the end of the hub axles..

EDIT: got the silver ring part to pop off, lots of effort needed on that one.

Had to muck around with the cone tightness and bolt to get it just right, when you do the bolt up the cone gets a bit tighter on the bearings. I'd read on Sheldon Brown's website that hubs with quick release skewers need some fine tuning, I thought before that it related to how tightly you did the skewers up against the dropouts when on the bike, but I guess now it's more to do with the bolt v's the cone.

When in doubt, consult Sheldon Brown

Well, there's definitely something going on with my bike, front wheel's running smooth (there's a slight rattle or something, have to take a closer look at it tomorrow).
There's something funny going on in the BB and also the back wheel if I lift it up and roll it, it slows down very fast.
Guess I've got a few hours of my weekend planned
