Gents,
Firstly, thank you for all your responses/information and advice.
Initially I decided to go with the 'easy' fix first as per Jims e-mail.
Before my long suffering assistant, a.k.a. the wife, arrived in the garage I
tried to lift the clutch pedal but it wouldn't move above its rest position.
However under the bonnet I could freely pull the cable inner out for a good few
inches.
With my assistant in place we then tried various methods of pressing/lifting
the pedal and pulling the cable but none of them resulted in a clicking noise
with the pawl re-setting when the pedal was pressed.
In view of this I decided to assume that the problem lay with the
cable/pawl/pedal and that the cable needed to be shortened in some way.
For all those with a sensitive/engineering background please skip the next
paragraph.
With the cable free I slipped a washer over the cable nipple and then found a
short length (1.25 inches) of narrow bore hose. I split this down its length
and was then able to push that over the cable between the nipple and the
washer. This was then fastened in place with jubilee clips. Theoretically the
nipple wouldn't pull through the hose and the washer would stop the hose going
through the hole in the lever. A quick press of the clutch pedal revealed that
it worked.
I then started the engine and the gear change was fine and it was still fine
after letting the engine warm through.
Arming myself with my AA card and a mobile phone I took to the open road and
after a journey of 30-35 miles the gear change was still fine. It may have been
imagination and it may have got a bit notchy towards the end. It may be that a
much longer run reveals that it is notchy and I may need a longer bit of hose
to shorten the cable a bit more. In the meantime I am going to enjoy the car in
our unexpectedly good weather 'up north'.
I do have plans to remove the dash and re-spray it once the nights start
drawing in so when I have it all apart I will investigate the segment/pawl
issue further at that time - unless it stops working in the meantime.
I do recall that when I was building the car Quantum did send me an alternative
segment which overcame the problem of there not being enough movement in the
pedal but I haven't been able to find the paperwork on that yet.
Once again thanks for all your assistance.
Regards
Phil

That's really only true on the Mk1 and early Mk2 Fiesta gearboxes.
These had the "gate" for the gearchange in the bottom of the gearlever and
there was nothing in the gearbox to stop you trying to move the gearchange into
incorrect positions.
So alignment of the gearlever to the gearbox was critical.
The later Mk2 gearboxes had the "gate" in the gearbox, you can move the
gearlever anywhere if it's not connected to the gearbox .
This setup is much more tolerant of misalignment.
Now, if you mix the early gearbox with the late gearchange (no gate at all) or
a late gearbox with an early gearchange (gates in both) then you will do really
well to get it to work.

Apologies for delayed reply, I accidentally didn't send this and just noticed
it in my Drafts folder...
If you can select reverse gear when stationary without it crunching then the
clutch is not dragging, also it's only necessary to reset the ratchet and pawl
if the bite point is too high and/or you can't press the clutch to the floor.
It should not be possible for the adjustment to be out in the other direction
(too much pedal play and/or clutch not freeing completely) because the
pawl/ratchet mechanism will take up the slack first time you depress the pedal
- unless the ratchet has a broken tooth, which is quite common.
A whirring noise in neutral might indicate a faulty gearbox input shaft
bearing or clutch release bearing, though a small amount of gear whine or
chatter is normal.
Provided there is no problem in the gearbox such as a selector clamp bolt
come slack, the usual cause of not being able to easily find a gear is a worn
linkage and/or worn gear-lever assembly or misalignment of the linkage and the
gearchange input shaft on the gearbox. Near the top of this page might be
useful. With the linkage in good condition it's essential to clamp it so that
the operation of the gear-lever assembly is "in sync" with that of the gearbox.

Subject: [Quantum Owners] Gear Change
Hi,
After 5/6 years off the road I have now got my 2+2 MOT'd but am working my
way though a number of teething problems as they come up.
The one that is causing some concern is in respect of the gear change. It
hasn't been good since I got the car back on the road but I went out in the
car yesterday and as I drove it became more and more difficult to select a
gear. At one point I was on the front row at traffic lights and was unable to
select any of the 6 gears that should have been available! That was
exciting/embarrassing. Eventually I managed to 'forcefully' select a gear and
get moving but every gear change after that was a bit hit and miss. Several
times I had to pull in and let traffic past as I tried to find a gear.
I finally plucked up courage to go in the garage this morning and investigate
- and I was able to select all the gears without any problems albeit the engine
wasn't running.
With the engine running and getting up to temperature it seemed to get more
difficult to select a gear although I didn't road test it because of the
problems previously experienced.
As part of the recomissioning I put a new clutch in but I have now noticed a
'whirring' which stops when I press the clutch pedal in. I am thinking that
the clutch is dragging which I understand would cause selection problems.
Should I have reset the segment and pawl at the top of the clutch pedal when
I put the new clutch in?
Would resetting solve the noise and selection problem? From what I can see,
or not see, this will probably require the removal of the dashboard?
Any thoughts/opinions/advice will be gratefully received.
Regards
Phil Holden
