I need directions on how to remove and reinstall the axle on a Specialized Stout Hub.

Thanks in advance,
Uni

Take the hub apart using cone wrenches like anyother?

davidad

Front or rear?

Don't know if this is related. https://www.specialized.com/ch/de/bc/...enuItemId=8855

There are no cones.

Here is a picture of a Specialized Stout axle, bearing, and skewer without the end caps. This skewer had to be sawed and the axle punched out since it was rusted to the cartridge bearing.
A new hub with axle and bearings installed is en route. I plan on removing the axle from the new hub and replacing the previpusly removed axle. It is probably a very simple matter, but since this axle is different from the standard cone/lock nut type, I decided to post to get needed directions.

Unicornz0

No,that video does not apply.
BTW, it's the front axle.

electrik

Awful. Well, seems to be straight forward.. i haven't worked on one yet but will have to in the near future.

Hopefully it's just a straightforward act of replacing the cartridge bearing, lubing the axle and sliding it in...

Let us know?

Unicornz0

I hope it is that simple. Before I can resemble the parts, I've got to find out how to remove the end caps, bearings, and axle from the new hub. And I have to do this with regular tools. I don't have any exotic presses or pullers.
Hopefully someone with previous esperience or knowledge will post directions.

Judging by your previous posts your next attempt will be to make titanium out of bread.

Just be glad it's a front hub and not the rear.. after looking at dt swiss's instructions for servicing cartridge bearings in their 370 line of hubs(you must disassemble the free hub, which will require at least two specific tools, to get to the bearings) be glad you're not me! Probably just warranty it, bearings weren't pressed right from the factory.

Unicornz0

Thanks for your post Electrik. I looked at the DT Swiss manual online & the 370 is remarkably similar to the Stout hub. The Stout hub can be disassembled without special tools so maybe the DTS 370 can be as well. My Stout hub does not have the dust cover that the DTS 370 has.
Here are some pictures.

did not find much info on Specialized Skraxle hubs, mostly Ritchey model Skraxle hubs.

please grease/anti-seize the Skraxle(Skewer Axle)when you put it back together, so it won't seize up.

Unicornz0

Thanks for the tip. Can you explain how to remove the end caps?
Thanks in advance,
UNI

Soil_Sampler

no.

little to no info on assembly/dis-assembly of these hubs.

I believe I remember reading that they(caps)were press fit.

Unicornz0

Yes they are pressed on.

davidad

If they are like my American Classics they are pried off. I use a screwdriver.

Unicornz0

Thanks, I do remember them being pried off. What area off the hub do I use for leverage and how do I make sure not to damage the area that is used for leverage? How do I remove the bearings, then after everthing has been removed from the new hub, how do I reinstall the axle, bearings, and end cap in the old hub and wheel?

Soil_Sampler

sounds to me like you should let a bike shop mechanic do this?

Unicornz0

Part of the entire biking experience is repairing my own bike. If I know how to fix it, I'll probably know how it works, and this will in turn enhance my biking experience. Moreover, I will know that the job has been done right, or at least adequately.

Soil_Sampler

I ask that, because of the amount of questions you have about a front hub that you already have apart.

davidad

I tried e-mailing specialized and they wouldn't help. They said take it to your dealer. At least at Trek you can get tech info without selling your soul.

Unicornz0

There is nothing wrong with asking. The more that I have asked about this upcoming repair, the more that I've learned about it. Have you noticed the flow of information? I've learned quite a lot about this Skraxle from this page.
BTW, I did not take the hub apart, but I plan to learn how to put it together
Experience is a great teacher.
DIY Rocks!

Soil_Sampler

ok.

Unicornz0

Ok Community this is starting to come together for me. But I still need help.
I really need help on steps 3 & 4, please explain how best to accomplish these steps.
1) I think I've found how to remove the end caps from the new hub, by prying them off with a screw driver.
2) Gently tap on the end of the new axle with a rubber mallet & that will remove the axle and one bearing.
3) Use a long nail to tap out the remaining bearing, with a large enough nail head to cover the inner race.
Or, would a socket/extension combination be better to press out the bearing by pressing as close to the outer race as possible?
4) Do I press both bearings into the hub and then tap the axle in? Seems like this might tap one bearing out. How do I install the axle?
5) Then tap the end caps on to the axle.

Thanks in advance,
Uni

I got this from the horses mouth and it was like pulling teeth, horses teeth.


Here is a small step by step on how to work on your hub:
remove aluminum end caps
- gently tap one end of the aluminum axle forcing the bearing out of the opposite end of the hub
- reinsert the axle into the hub shell and remaining bearing
- gently tap out the second cartridge bearing
- service/replace the bearings/axle as necessary
- find a section of tubing which matches the OD(outer diameter) of the bearing
- gently tap the bearings back into the hub shell making sure that the piece of tubing does not contact the hub seal
- check the hub for axle play, or friction. loosen or tighten the bearings as required
- install the end caps
- ride

If you damage anything it will in no way be covered under warranty. I hope this helps.
