I'm trying to dismantle an bmx hub. I have taken all the stuff around the hub off and now I am just left with the hub and axle. The problem is I can't seperate them to clean the bearings. I have tryed hitting it with a hammer but it won't budge and I scared of damaging it. Any advice for getting it out.
Some pictures of both sides of the hub

thanks

Sound like a sealed hub and the axle needs to be hit out. If the pics are too big can you link to them.

Yes, this has sealed cartridge bearings. You need to support the hub from the drive side and knock the axle with a hammer, that should drive the bearing out from within the ratchet taking the axle with it. To refit (new perhaps?) cartridges, you make be in the shit if its a 14mm axle as the axle wont fit through a 1/2" socket driver. Typically refit cartridge bearings with a socket bit that has the same outside diameter as the bearing.

Make sure you remove that locknut first though!

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:
![](https://www.google.co.uk/images/srpr/logo4w.png)
That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
