[Quantum Owners] Re: 2+2 Clutch adjustment
I've had a similar problem with the clutch on my 2+2 over the years. My current working solution is to modify the auto adjustment quadrant to increase the distance from the pivot to the cable, thus increasing the amount of cable moved when pushing the pedal. This modification consists of 4 countersunk 15mm bolts (about M6 I think) going through the quadrant and refitting the cable over the bolts. As this problem shouldn't exist anyway, I did a little delving into the root cause. The most popular theory is the pressure fingers on the clutch cover softening over time and not releasing the clutch properly. I haven't changed the clutch cover on mine at all, not even on build (in '93), so this makes sense to me.

RE: [Quantum Owners] 2+2 Clutch adjustment
QSC Stourbridge recommended replacing the MK2 Fiesta quadrant with a MK3 Escort quadrant because the channel is shallower. Effectively this makes the cable shorter. -Original Message- From: quantumowners@googlegroups.com [mailto:quantumowners@googlegroups.com] On Behalf Of Jim Hearne Sent: 27 May 2012 20:48 To: quantumowners@googlegroups.com Subject: Re: [Quantum Owners] 2+2 Clutch adjustment When you were removing and refitting the cable were you holding the pedal up against the stop to release the pawl ? When you refit the cable you need to also hold it against the stop and pull the quadrant right round to reset it. The tab shouldn't need modifiying on a Quantum but some of the build manuals do mention putting spacing washers behind the pedal box and making sure you don't have thick carpet and soundproofing behind the clutch pedal as it can stop the auto adjust working if the pedal hits the bulkhead.

[Quantum Owners] Re: 2+2 Clutch adjustment
Chris Already had the larger radius quadrant fittedit was the replacement one (now junked in favour of the original) that resulted in complete failurewhilst the larger rad one does make the cable shorter, more importantly, it gives more travel of the cable for a given pedal movement. End of the day, the bite point is just very lowwhether this is due to a problem with the clutch itself or the pedal box as it's fitted to the Quantum I don't know but I suspect the latter as it seems like a very common problem. I think that the pedal is actually bottoming out on the carpet but I can't really see if it's hitting the floor before it hits the stop on the pedal box but if so then that would certainly explain it (different floor shape in the Quantum to the Fiesta maybe?) Anyway, filing the adjustment point tab on the pedalbox seems to have done the job On May 28, 7:58 am, Chris Fairlie chris.fair...@btconnect.com wrote: QSC Stourbridge recommended replacing the MK2 Fiesta quadrant with a MK3 Escort quadrant because the channel is shallower.
