I tried re-tightening it, putting a new heavy duty screw and nut in, using loctite, but no matter what i did it still came loose.
I'm using a spool in the front, and aluminium centre pulleys with a direct driveshaft (if that makes any difference). I am using the standard kit diff that comes with the Cyclone S
Any help would be appreciated!
