Looks naff and I'm sure it won't hold long. I'll give the hot water soak a go.

Never had this trouble with my ten quid Planet X pump. "Upgrade" pfft.

Mine isn't much further in than that, but thanks to

a bit a Superglue on the new spigot

It's been fine for the two years since I did it.

Hot water got it over the second thicker section. I'll try that.

Is the lever supposed to actually lock it onto the valve?

Yes, you need to adjust the threaded ring to compress the rubber grommet such that it's bore slides easily onto the valve stem and then constricts when compressed by the lever/cam system to hold tightly to the valve.

I see. What's the point of the screw at the top of the head then? Just to stop it rotating too far?

The small screw opposite the air pipe/spigot holds the roller follower for the cam.

Not an adjustment for the cross torsional tension pulverizer machined inverse spigot shim flange then? I am disappoint.

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

> Quote text by starting lines with >

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.

If you upload more than 5 files we will display all attachments as thumbnails.
