I have a Flymo 400 and I needed a retaining clip to stop the pivot pin from constantly working itself loose, and falling out.

This is the pivot pin, Flymo Pivot Pin
£2 seems to be a lot of money for a simple retaining clip. However, if you are in Bangkok, then, for an absolute bargain, go to:

This is the shop front
There, I got a Size #10, #12, #16 and #20 all for 10 baht, or 20 pence.
seem to be the best fits, both with respect to the wire thickness and the hole, as well as the snugness of the fit of the kink in the loop against the side of the pivot pin.
However both sizes #16
have the wire a little bit too thick to fit in the hole and not as snuggly in the loop, although they do still fit.
Fitting the clip
However, the official Flymo assembly video does not show a retaining clip being used, or rather it shows that no retaining clip is used, see How to assemble the handles on the Flymo Turbo Lite 330 & Turbo 400 at 0:06 to 0:18
Indeed the underside does not provide access to the end of the pivot pin, in order to push the retaining clip through. See photo.
However, removing the orange top and then the grey motor mounting, could provide access.
Removing the orange top is easy, just remove the philips screw in the top.
Removing the grey motor mount requires access to the screws from beneath.
To do that you need to remove both the blade and blade mount.
Removing the blade, Changing the lawnmower blade on a Flymo Turbo Lite 330, & Turbo 400 at 0:15 (or How to Replace a Flymo Lawnmower Blade, @0:43. Basically you need to turn the bolt anti-clockwise. Note that this is easier said than done on an old Flymo. I ended up using a hammer on the spanner.
Then remove the seven screws, securing the motor mount from underneath.
Then you can gain access to the pivot pin ends.
However, there is not enough space to push a retaining clip into the end of the pivot pin… so that was a bit of a waste of time! 🙂
However, by winding a length of something, for example fuse wire, around the end, whilst the pivot pin is in situ, in order to make the end wide enough to prevent it from slipping up, it is possible to make the pin stay in place.
Alternatively, fit a size #10 retaining clip, not around the pin, but end on, like this:
The clip does not go all the way through, but the grey motor mount should stop the clip from falling out. Not ideal, but does the trick.
As an added bonus, having cleared out years ‘worth of old dried grass, the Flymo actually hovers now, and is a lot easier to push about.
