Thanks Storm, so it shouldn’t be loose like this? I have put the grub screw in with lock tie, but I’m guessing its doing nothing if its not on the Centre shaft itself?
I will take it all back out and have a look, I can’t remember a flat bit only round but will take out and have a look.
don’t suppose anyone has a picture for me to help?
arr no problem, will take a look at what storm said, but I didn’t think the grub screw gripped the shaft as there’s a red o ring between them. Hopefully someone else can help.
good luck with the sale.
