I have a bite point above the floor, albeit low. Happy Days. So I will try to find an exact replacement clutch kit. Also Geoff Ward provided a copy of the pedal box modification from the late build manual which is supposed to help too. Thanks for all you help and advice, especially Andy Heaton who helped me to take the engine out again this afternoon.

There were 2 lengths of clutch release lever used that match up with the 2 cable holes in the gearbox that you've seen. As you say, the shorter level will give you more movement on the release bearing for the same cable movement but at the expense of a heavier pedal. I'm not really sure why there were 2 lengths but i've always used the short lever. I guess it's possible that the long lever was for the low lift bearing which needed less movement. As has been mentioned, the lever can shear off where it is welded to the shaft, also the bolt can shear off where the release bearing bracket is attached inside the gearbox/ The later gearboxes had a different lever arrangment which attached to a separate shaft via splines and a pinch bolt.

Unfortunately it is too late to make more checks as the engine/gearbox are out again. However I can confirm he clutch pedal was going to the floor. Actually I was hitting the Fiberglass bulkhead as I removed all the carpet and sound deadening from behind the pedal just to eliminate that concern. My other thought is the gearbox has two holes for the clutch cable to pass through. I am starting to wonder if I can use the other hole which means tha cable will pull on the release arm nearer to the shaft so I get more degrees of turn for a given movement of the clutch pedal. I know this will lead to a heavier clutch pedal, I need to find something that will work. This would need a different, shorter, arm of some sort of mod to the existing one. While the gear linkage UJ is a little stiff. I had no problem selecting gears before taking the engine out and I can select gears easily when the engine isn’t running. So definitely the clutch is dragging even when the clutch pedal is fully depressed.

The movement of the cable will only be 10% more with the 55mm quadrant - Is it possible to check how much cable is pulled when the clutch is fully depressed, in order to get an idea whether the arm will nearly reach the limit (ie hit casing)? Does the pedal hit the floor, or could the arm move more if the pedal was able to move more (ie bigger quadrant will help by 10%) if that makes sense. Just trying to get an idea of the full picture....... All knowledge gained before tackling the job is probably worthwhile. I went round in circles with replacing quadrant/cable until I realised the issue must be the clutch (also had the gearchange linkage in bits, and although that wasn't the root of the problem it was too tight) Martin ----- Original Message ----- From: 'Chris Fairlie' via Quantum Owners Group <javascript:> To: quantu...@googlegroups.com <javascript:> Sent: Thursday, September 06, 2018 1:16 PM Subject: RE: [Quantum Owners] Re: Help needed with a 2+2 clutch problem Marin No slack at the gearbox or pedal end when depressing the clutch Chris From: quantu...@googlegroups.com <javascript:> [mailto:qua...@googlegroups.com <javascript:> ] On Behalf Of Susan and Martin Scott Sent: 05 September 2018 22:09 To: quantu...@googlegroups.com <javascript:> Subject: Re: [Quantum Owners] Re: Help needed with a 2+2 clutch problem Hi Chris, If I recall correctly the Escort quadrant is the 55mm black one. With an observer, is it possible to see if the arm starts moving when the pedal is depressed, or if there is a delay indicating slack being taken up. Could also 'twang' the cable at the arm to guage if there is any slack.

Martin I refitted the pedal box and fully depressed the clutch. The is still quite a bit of travel on the release arm. So looks like there is an issue with the adjuster and or cable.

My fix was to modify the white quadrant to increase the radius to the cable and increase the amount the cable moved. Eventually I fitted a quadrant from a Mk3 Escort (81-86), Ford part number 78GB7L583AC. This was coloured black (I don't think that means much). This had a larger radius and solved the problem. The bite point is still on the low side but doesn't create an issue.
