Another Spider Query, accelerator cable...

OK, this one has me stumped.
Last weekend the spider was crusing along OK then the motor
just went to idle and the accelerator pedal fell to the floor.
No biggy I figured, broken cable. Back home I checked the pics
of the parts in the manual and the drivens end of the cabel is supposed
to just plug into the end of a bar with a plastic plug. I expected to find
the plug or something close to that end broken or snapped.

This is what I found.


Looks nothing like the manual pics and the cable comes from the wrong
direction, note the arrow shows what direction the rod moves when the
pedal is depressed. This means the cable has to come back around
for the rod to be able to pull on the cable to work the throttle properly.

My question is, is some part missing that I'm not aware of? The rod
has a part that is bolted into it and an adjustable screw section that
doesn't appear on the parts list. HELP!

I've ordered a new cable just in case it can shed any light on this issue
but I'd love to be able to fix it without resorting to replacing the whle cable.

Cheers, Rod

Am i going nuts or is the accelerator on the left in that pic?!?
Whats going on there!

Whats at the top of the accelerator pedal?
Its welded to a "cross bar" of sorts, is there something at the top of it? or another bar coming off it? (above the shiny threaded rod)
Though it doesnt explain the white plastic "holder" thing on the accelerator cable!

Any snapped/broken bits in the foot well?

Maybe a better series of red bits to explain.
The accelerator pedal (marked as A) is attached directly over the top
of the pedal box to the rod near the cable, the arrows show the
direction they move in.
B is the brake pedal and C the clutch pedal.

The end of the accelerator cable is circled, that white plastic bit below
it is part of the clutch pedal assembly. You can just see a small metal
block on the end of the cable and on the end of the rod is a yellow
metal adjustable thingy which is not what I expected to find there.
(lower question mark)

The cable needs to be pulled to work properly so it should connect to
something that the rod can then pull on.... I've had a good fumble
around and can't find any loose bits anywhere although there are two
holes in an aluminum panel just left of the clutch pedal where something
could be mounted. The pic is taken from the passengers foot well, you
can't see much from the drivers side with all the pedals hanging down.

It looks like the pedal pushes the sleeve rather than pulls the cable. Does the cable go through the 'yellow metal' plated bezel thing on the end of the accelarator pedal arm/extension? Then the actual end of the cable is located higher up somewhere in a fixed position. So when you push the pedal the sleeve is pushed down.

Give that man a prize! I was scratching my head over this one too. It's a wierd way of doing it but I have seen cable fed clutches do the same,

how does a bicycle brake work PMSL!!!

Hmm
Bowden cable 'push' on the outer sleeve would be very unusual, all sorts of nasty things could/would occur (though nothing is beyond Renault design ), for i.e if the outer sleeve moved you would have to consider it's wear on all around it (and no sign of wear on the grommit that it passes through), friction etc, and if the outer caught on somthing then you throtle would remain open.

Much more likely is the inner is pulled, but are you looking in the right place Biologist ? Are you sure there is nothing up near the peddle axis that would form a pull rather than a push (even, and most likely at the left side), the Bowden even when relaxed seems to bend upwards. Turn it up by another 90o, anything there in it's reach?

yeah but...

at the other end, at the throttle, the sleeve will be fixed and the cable moves so there actually isn't much movement of the sleeve to cause wear, probably all taken up in the loop round into the tunnel back to the engine.

It would also work if the other end was sprung heavily enough to pull the throttle open when the pedal was pressed. But that would be quite a poor design as the engine would be stuck on full throttle if the cable snapped or became detached from the pedal.

Crikey I think your right!
Looking at the pic again I think I've labeled the pedals wrong. "C" is probably the
footrest and that plastic clip could be where the end of the cable is secured...

I've not tried to see if the cable goes through the yellow metal piece but
if it does then thats it. Note also that the clutch cable operates by pushing
the cable sleeve. Its hard to tell from the pic but I worked this out last night looking
at the the parts manual.

Indeed its a strange way to work the system but heh its worked so far.
What seems to have happened then is that the cable end has popped
out of its clip then bingo, no accelerator. If this is the way to go I'll have
it fixed tonight And of course I'll be making sure that cable end
doesn't pop out again.

Cheers guys your great as usual

Rhd spider road car is equipped with the race car pedal box....(tubular the Lhd road one has solid pedal arms) the cable has a plastic lug on the end which plugs into the pedal assembly it does pull on the cable.

....normally what happens the cable freys somewhere along and then catches..... goes a little stiff.... you boot it..... snap..... and normally it gives at the pedal end as it's plastic..... order a complete new one.....

but check when you do as the Rhd one may be longer than the lhd one I know the clutch cable is for sure....

good luck

ITS FIXED.
Took me five minutes and a piece of gaffer tape and a zip tie

The cable does indeed slide through the cylinder of yellow metal
and pops into the white plastic clip. I may have lost a retainer of some sort
to stop the cable end popping out so a length of gaffer tape around
the clip and a zip tie to be sure and all is well. Went for a decent drive
and she lives again.

I still have an accelerator cable on the way and yes the RHD drive cable is
darn long, it runs all the way round the LHD side of the car and must be at
least 4 metres long. It'll come in handy one day I suppose.

Thanks for the insight guys, much appreciated.
