Is the cable fully stretched?
It may help to get a special tool which is called a 'third hand'. It
grips the cable and makes it taut so that there is no slack in the cable
when you tighten it.
HTH
i will try that thanks for the reply i am also replacing the cable
i have even replaced camle now still not working i tried to disengage
clutch by moving the arm with a pair of pliers still no joy
Make sure the cable is fully stretched before crimping it down.
