Good afternoon.
First time my Plus 6 saw the sunshine in Scotland a few weeks ago the cap was stuck as you all have noted.
Eventually got it out and tried all the silicone ideas etc but it was much better when cool in the garage.
Cut it off tether and Took it to bits, tightened it a bit but was just not right still.
It has never been good from the start and was always a mystery how and when it opened.
Looking at one of the threads on here I spotted the manufacturers name stamped on the bottom of the black plastic.
They are made by Newton-Equipment.
It is the Aero 200 model.
On the website there is a choice of the black plastic saddle or a cast metal saddle.
Strangely the shape is different but more importantly the spindle locates in a metal hole rather than a plastic hole.
It looks like the lever has been turning in the hole in the plastic and worse when hot.
2 days delivery from Newton-Equipment and new crimps for tether.
10 min to fix will do tether in winter as think filler needs to come out to do it but looks straight forward.
Plastic ones are £6.66 and metal £20.90 plus vat.
.£30 ish to fix on a £100k car!
Also new Morgan now apparently come with the metal saddle!
Photos too big to attach.
Anybody need them let me know.
