Hi John! The CRB failed in a spectacular manner - much noise, vibration and no clutch disengagement. Got home by starting on the starter motor in second and crash changing the rest of the way. I have read the guide (v.good) on pre-loading the CRB and will do so once I've located suitable springs as Caterham no longer stock the recommended ones. As the SKF bearing seems to be in short supply, I've sourced two from separate people, one being Caterham's last one for the moment. Two CRBs, two clutch cables, two throttle cables - maybe a spare "K" in the boot? Nick
