dura ace track hubs...adventures in overhauling!!
It's been about two years of riding in the rain and snow, on my poor high flange DA track hub...And I've been putting off overhaulling it for quite some time. Tonight, I decided, was the night.
So I disassemble the hub, clean all the parts, cones, bearing races on the inside of the hub, and the bearings. I inspect everything for pits, deformities, anything outside of normal wear and tear. Everything appears to be clean, I re-lube everything, put it all back together, and it's a little crunchy, and nowhere near as smooth as the newer, front hub, which I did not take apart. I take it apart again, check for wear under BRIGHT light, see nothing on the cones aside from the line where the bearings run, it's not a divit, just a little line. A few of the bearings have a little line running all the way around them, but there's nothing I can do about it at the moment, so I slather everything in grease, put it all back together, and it's a ltitle smoother, but still not as smooth as it used to be...
Everything is adjusted properly. (Can anyone BELIEVE the tiny-ass slots for the cone wrenches on these things!? They're like, thinner than a dime!!!) OH!, and when I opened up the hub, it was clean. There was only a little grease in there, but no road grit at all! So...My conclusion and questions from tonight's exercise are:
1) I should replace all of the axle hardware, and the bearings, rather soon, given that they have been abused by the harsh Boston winter weather.
2) Does shimano use some kind of super grease when they send their products out from the factory?
3) Should I procure this uber-grease and use it in the future (I use the Park Poly-lube, which I've heard is pretty good from just about all the shops i've been to)?
4) Should I put even more grease in there, just in case, or leave it alone? I put A TON of it in there, i mean, really...I've heard that you can't really put enough lube into the hubs, but really...this really seemed like enough...
I really hope my hub is not shot. It would really make me sad. this was my first real track wheel, and I've grown rather attached to it...I'm thinking that as soon as I have the money though, I'm going to just buy some phil woods.
Sorry if this is a little long, i tried to include all the info that i possibly could...
