Split BB Cup

Just installed a brand new Shimano sealed bottom bracket, a UN-something-or-other, and noticed as I was popping the cranks on that there is a crack in the plastic non-drive side cup.

It runs radially and I haven't had it out yet to see if the whole thing has split. I don't think I overtightened it, but I'm not sure what else it could have been? Will this actually matter as it's just the plastic bit that accommodates the sealed unit itself? Is it readily available separately?

Thanks ladies and gents.

I would'nt worry about it ,but everytime i rode ,I'd feel like i was riding something flawed.I'd imagine you or your mates must have plenty of spare ones .Fit another when your ready is what i'd suggest

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:

```
Your code goes here
```
Just like Github, a blank line must precede a code block.
