3rd time lucky!! What a horrible job. I filmed it all so hopefully it will help others in the same situation. I'll compile that later. Recived a call from Midnight Motors in Watford today who found me an old copy part that they used to sell back in the day... high tailed it up there to get some great advice and a great part! once home i swapped over all the bushes and parts over to the pedal to find a working ratchet, success!!
I'm not going to lie, putting it back together was a nightmare. Easier with this part though. In the end I set the quadrant/pawl, that rested on the plastic bushes just enough (the old one didnt) to slide the spindle bar through the pedal. Then after a few tries I got the clutch cable through and clipped in (again it wasnt on the old part) then I used a guitar string round the handle of a hammer, though the eyelet of the clutch pedal to pull the return spring into its rightful place, with the nudge of some pliers from behind. After this it was easy enough to fit the brake pedal and clip it all in.
The only other issue I had was getting enough slack on the clutch cable. At first with the Quadrant set to its most neutral position I couldnt get it to reach the gear box. Lots of head scratching and thinking about putting the old Quad back in passed and then after another go it must have moved down the ratchet a bit to where the black quadrant was sitting. Then I had just enough slack to get it on the gear box fork.
I guess this means the clutch is about half way worn? Either way. Went for a drive and it was a lot better! even managed a pretty low powered wheel spin which used to send the old quad into a hissy fit.
I might sound like I want a medal for this job but it was pretty claustrophobic and twinged my back etc so, thought a good write up and video to follow would help others.
