I know it's bin asked a couple of times lately but.....can anyone that's successfully carried out this conversion give me any pointers as to what i've done wrong????! Thing is, i've done everythin as per the ap racing website, chopped off the 10 teeth as it says but the pedal still sits horribly high. Had to adjust the bolt to get the clutch to disengage and sits horrible to be honest. Do i chop more teeth off???? I'm gonna put the old pedal back in at this rate, never really had a problem with it!

don't follow the ap website mate(very weak quadrant that way), tbh from wot i can gather your best bet other than a solid metal one is a standard mk4 quadrants as it is is less of a half moon and gives a better pedal position once set

@ rstdave,as I posted on here only a few days ago this is what I did

Right lads,hot news straight off the press.I re- did this job today as when I 1 st did it last week my clutch pedal was sitting too high.After reading on here of the modified mark 5 qaudrant breaking I deceided to try the origonal mark 4 quadrant (BLACK in colour) with the mark 5 pedal.I adjust the bolt on the pedal until the clutch pedal was sitting a touch higher than the brake pedal and the clutch worked perfect!! A slight problem was that the clutch cable could be pulled of the gearbox arm easy,so I put a cable tie on the end of the gearbox arm so the cable wont slip off.To be fair,I dont think the cable ever would,but used the cable tie to be sure.I think my way could be a good solution to the problems with the modded mark 5 quadrants.All the best,Micky

Cheers for the tips........unfortunately i tried the solution above but still to no avail!! Really pissin me off, had the pedal out god knows how many times now, thinkin maybe the cable's stretched perhaps...was workin fine before tho with the old 4 paddle clutch!

SafeChav

can you not get the pedal height down even with the bolt fully out?

rstdave

well with the bolt fully out the pedal sits lower, still a bit high but won't then disengage the clutch due to less clutch cable bein pulled through. Startin to think somethin's not as it should be cos put the old pedal back in and that won't disengage the clutch either! It's a new clutch, ap cp200-35 which i fitted to my new engine when it was out the car so never actually had it runnin before

SafeChav

undoing the bolt shouldn't affect how pull you get on the clutch

Thats wierd

wul young

had very same problem,fitted mk6 pedal and qudrent,pedal was sitin way high with hex bolt backed right of,fitted mk 5 clutch cable from 1.8 diesel with mtx 75 box,this was way bigger but slack can be taken up by tightning hex bolt,also mk5 and mk6 also have a retyrn spring on pedal to pull clutch pedal downwards as there is no resistance on pedal when pulled up due to the ratchet and pedal design,it is on all mk5,6 with mtx75 box,it can be hooked onto pedal then hooked onto pedal box of mk4 with no mods,it clips in no probs,this does pull pedal down quite a bit,hope this helps.

SafeChav

could be wrong but im sure its only the mk6's that have the return spring, all the mk5's i've seen have self adjusting pedals, mk6's are all manual adjusting.

wul young

im sure about this m8,ive just finished mtx75 conversion and had problems in past using ib5 box and various paddle clutches ,ive done a lot of messing about to get good pedal setup,on both boxes,i have looked at loads of mk5,6s in scrappys,if it has mtx box,every 1 i looked at defo had return spring.

SafeChav

Theres only a handful of Mk5 escorts that have MTX boxes anyway though

wul young

i would say theres a bit more than a handfull,all the1.8d, 1.8 td models run mtx box,and mk5,6 escort diesel vans also run mtx.

but yes theres certainly more of them with ib5 box than mtx.

SafeChav

ah ok fair do's then.

I know all the lower model Mk6's still have that spring on the pedal though as ive had a couple off myself

pee vee

Right, this is beginning to get stupid now.

can someone post a picture of the MK4 pedal box please!?
Im beginning to think there is something bent/broken on RSTDAVES one


also, WHAT is supposed to stop the clutch pedal moving up past the normal 'stop' position, when you are using the MK5/6 pedal????

as far as i can see there is nothing..

At the mo Daves clutch does work, but it bites RIGHT on the floor.. and when you let the clutch off the pedal moves all the way back up, only being stopped by the steering columb

this is clearly wrong, and cant be put back on the road like this..

PLEASE HELP!!!! thanks

Chris69

have ya got the right cable phil, sounds like its too long or something, the tension on the cable from the clutch should stop it returning all the way upto the column for a start
not too sure why its biting right down on the floor though thats weird

pee vee

well its the cable that has always been in the car

but i was asking dave the other day if you are supposed to have the MK5/6 cable to go with the pedal!?

maybe its just that little bit shorter either way.. when there is tension on the cable, the pedal springs up and is only stopped by the steering columb

Im beginning to think there is a stop or something missing from the pedal box TBH

as the pedals have all gone back in according to the diagrams (spacers ETC)
just substituting the MK4 pedal and quadrant for the mk6 one..


OOONLY other thing i can think of is,,, the mk5 and mk6 pedals are different!!?? as we are using a MK6 one

SafeChav

Obviously yes the Mk6 pedal differs from the Mk3/4 one, it doesn't have the stop on it.

Are you using any springs on the quadrant because it just doesnt sound logical it bites at the floor yet rises as high as it will go?

Micky

There is nothing to stop the clutch pedal from coming all the way up high,so you're correct on that score.Have you tried what I posted above??Regards,Micky

MarkXr

Maybe that's the problem! There are 2 types of cables for the Mk4. A long one and a short one.

The long one runs all the way to the front, makes a 180 and the outer cable is connected to the clutch release arm and the inner cable connected to the gearbox housing.

The short one runs from the pedal DIRECTLY to the gearbox with the outer cable on the box and the inner cable pulling on the clutch release arm.

Obviously the short one will be much more responsive and as a matter of fact AP recommends that people should use this cable. Take a look and if not already fitted, fit a short clutch cable. Not saying this is your problem but it's my best bet at this point!

pee vee

We have tried all sorts of combinations now including yours, yup!
as i recall that combination (black mk4 quadrant in mk6 pedal) and it simply didnt pull enough cable to release the clutch..


have used both quadrant spring and the spring that holds the clutch Down
on both pedals now... generally the quadrant spring almost does its job,
but the spring that holds the clutch down is far too weak to stop the pedal coming way too far back up..

Daves has the short one that you describe outer casing plugs into the hole on the gearbox.. the inner connects to the arm!

SafeChav

The long cable is effectively the same length in terms of functionality, both the inner and outer are extended to allow the cable to fit around the ABS modulators.
