Hello Chaps,

I want to replace the bearings on a pair of Mavic 501 hubs, but as usual for such a simple task there is an impasse, which in this case is the damn bearing cover with the six holes. It's stuck fast and I don't have the mythical tool to remove it, a two prong pin spanner won't budge it either, any tips as to how to unwind it?

The "mythical tool" is still used in every Mavic wheel set, so every shop will have one. If it's seized, try GT85 or WD40 first

If you get really stuck, use the skills us humans got sometime after we evolved from being monkeys, and make a tool. I'd suggest 6 small bolts through a bit of bar might do the trick.

The 'mythical' tool is the heavy duty 6 pin item, the 'freebie' tool you get with wheelsets is the 4 pin plastic jobby.

Anyhow it's off now, a youth in a local bike shop went around the back with it and returned with the siezed part separated.

Plus gas Ugo and op that a proper penetrative fluid. We 40 is dish water in comparison.

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

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