I had a problem with my clutch pedal staying a the floor on my ph II GLX because the lever arm had dropped and the lever arm was getting stuck, probably because the bearing was being pulled off the end of the shaft.
I fixed/bodged it by adding a collar on the lever arm to keep it lifted up as I couldn't face removing the gearbox again
I think there is a plastic locating bush at the bottom of the lever arm / fork that must be damaged, but it works fine now with this permanent temporary collar.
