Hi all,

I have a yang ml-25a and have a turret indexing fault. When it indexes round to change tool it doesn't always lock into the station. You can spin the turret freely until it finds the next station or sometimes it throws an error code with the annoying alarm beep to say it doesn't know what station it is in. It used to do this once every few months but is getting more frequent. A few times an hour now. I've taken the covers off and there is nothing obviously loose, worn or broken so I'm at a loss to start pulling it apart.
Any suggestions and help are welcome!

Many thanks!
