I've replaced the cassette and the freehub body slid off. It goes back easily but the end cap - the little piece being pushed back on in pic 6 here https://www.powertap.com/Uploads/PDF/PowerTap-Manuals/powertap-g3-g3c-hub-manual.pdf won't stay put and if I leave it loose the wheel won't go back between the dropouts and would presumably just fall off if I have to take the wheel out!
Should it just click back in, does it need a bit of a tap with a (small) hammer?
If you haven't got a headwind you're not trying hard enough
