Anyone know the large nut that holds the stator on the crank ? It NOT what Dragonfly say , cycle 5/8th 20tpi as I have one and it will not thread..
thanks for any suggestions
It is 5/8 20 tpi cycle. Likely to be dahage to the thread on the shaft or inside the nut if they won't screw together.
sorry but what is dahage ?

Did you buy it from someone on ebay - "lister" something or other was the seller name, if I remember correctly. I think the threads are the wrong angle. I think there is a topic on here from a few years ago where I asked the same thing.
If so, I bought one from him and it claimed to be the right thread, but it wasn't. It would screw down a bit and bind. When I emailed the seller he claimed he'd sold loads and not had complaints, but it was kak! The one from Draganfly should be right.
Measure and confirm is is 5/8 x 20 just in case someone has forces a wrong nut on or recut it. If it is they get a 5/8 x 20 CEI die, they are only about £12 and you can carefully re-cut the thread.
I've had the same issue with "correct" nuts etc
also be careful on the drive side lock tabs that the correct nut is used - to allow the nut to securely hold the rotor tight.
some lock tabs do not allow the nut to pull onto the threads.
some nuts have a waist and some are plain , so take care - I had a dreadful "bottom falling out of the engine sound" and all it was , was the nut not pulling the rotor tight !!
Dragonfly are in stock now - have ordered one will see ..
