Hi guys,

Have an AP clutch in my car and done the recommended pedal mod just like AP told me to.

After about 1000 miles this happend to the quadrant:



Leaving me somewhere on the road with no clutch. (did manage to get it home in one piece but horror happened when trying to get it in the garage)

Any of you who's done the mod encountered something like this? Going to Ford tomorrow morning to get a new quadrant and then after that back to the bloke who painted the car.

A friend of mine is now doing some metal ones of these because the same thing happened to him

Fiecos Dan

same thing happened on my fiecos twice.

so i made a alloy one, and made it adjustable with a bolt.

Chris69

same thing happened to me twice mate, i've just put in a metal one i had made up at work- that won't break

vroooom ptssssh

Ap say get a mk5 pedal, but im told its actually meant to be a mk6 pedal?

Fiecos Dan

Here's mine. 12/05

Okay so it's a common problem with the "uprated" pedal mod.

Looks like I have to make a alloy one myself. First thing tomorrow morning is to get a new plastic one and fit it to the car.

When "driving" the car inside the garage yesterday by help of the starter motor this happened to my freshly new painted motor.........



I couldn't push it because it goes slightly upwards and it's a tight corner I have to make to get it in. Normally it isn't a problem, just fairly tight. But I was concentrating on "driving" on the starter and crushed into the garage wall. I could kill myself at that moment!!!

But okay it happened and tomorrow after fitting a new quadrant, straight to the painter to hear what he has to say. Hopefully he can repair it without leaving any signs of this disaster. It's a real shame, it was mint!

SafeChav

Hmmmmmmm........this seems to be happening very frequently now.

Maybe using a 55mm quadrant would help resolve the issue, the white ones are 58mm so they are under more stress.

Sorry to hear about your scrape aswell

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

vroooom ptssssh

My mk3 pedal sits high as fuck, any idea why?

Chris69

i've used the original(mk4)black and modded as per ap website white one, both broke in the same way so don't be suprised if it does on urs aswell
heres mine i had made up

Micky

Hi mate,I dont think you,ve read my post correctly,I didnt mod my mark 4 quadrant (BLACK one)!!So I cant see how it will break if its standard.Regards,Micky

Fiecos Dan

mine was a std setup, Not the ap mod.

So chances are your latest setup will also break.

Chris69

i didn't mod it either mate, thats the point i was making.
I modded the white one at first then that broke.
so i replaced it with a standard mk4 black one as you have, not modded in any way and that also broke- as you can see in my pic

SafeChav

Thats not an original Mk4 quadrant though.......its a Mk5/6 one.

Where do you think the name QUADrant was derived from.......

Chris69

thats the one ford gave me and said it was a mk4 one
to answer ur other question, is it cus they used them on quad bikes- would explain them being so weak

SafeChav

Whats the first 2 digits on the part number on it i cant make it out from the picture?

Micky

The black quadrant above is not a Mark 4 one as it has too many teeth,ans is half moon in shape.A Mark 4 quadrant has less teeth and is more like a quater circle in shape,as SafeChav siad,thats where the name came from.

click ere for a picture of a Mark 4 quadrant,hold you're curser over the picture of the white Mark 5 picture to see it.

Chris69

that sucks i was sold that as a mk4 pedal
sorry for the post hijack i'll bugger off now i've bin put in me place

Micky

chunt,wouldnt worry about it mate,sure you have a nice metal one now,will last forever!! Regards,Micky

MarkXr

Your self-made quadrant is superb. Have to get me a piece of alloy, I'm not waiting for the plastic shit to break again.

Been to the bloke who painted my car and he assured me it will be as nice as it looked before this happened. HOPE SO!!!

Thanks all for your replys......

i have just become another victim

can somebody make me a metal quadrant?

SafeChav

why the fuck are these things so weak.

Everyone seems to be snapping them all of a sudden

Maybe i wont bother doing mine after all

MarkXr

Maybe we should inform AP-Racing about this and get them to mill some alloy quadrants for us.....

At cost price obviously, we already payed for the clutch.

(for the ones who are interested, the damage to my car is repaired and looks great again. )

how long did everyone else's last?

mine lasted about a year so about 5000 miles?

i have just had to buy another one to re-do the mod as i can't make myself a metal one

dave_y

iTrader: (4)

good idea!

i have just sent an e-mail to AP Racing! see what they have to say for themselves

MarkXr

Right, can you forward me the mail and include AP's mail address?

I'll send one too and if I have your mail as wel it's easier to "make up" a story that describes the problem the same way.......

Thanks in advance,
Mark

BTW: Mine broke after less than 1500 miles......

EDIT! Forgot to mention my e-mail, it's markxr@fordweb.nl

for some reason it is not showing in my sent items on hotmail it has disappeared off the face of the earth so i wont be able to send a copy till they reply.

i sent the email to

sales@apracing.co.uk - for General Sales enquiries
roadtech@apracing.co.uk - for Performance Road Car technical enquiries

in the email i linked to this web page showing how many people have suffered from the quadrant snapping too.

i mentioned in the email how you were left stranded with no clutch and after around 1000 miles after fitting it.

i will let you know what they say when they reply.

SafeChav

I was thinking about this the other night, and it is obvious the reason the quadrants are snapping is because of how the pedal assembly works.

No doubt the angle the bolt pushes against the quadrant over-stresses the quadrant and hence why the weakest part lets go.

How far in/out have you people got the bolts adjusted on your pedals?

Excuse my ignorance, but can anyone explain to me (in lamens terms!) as to why this mod is needed in the first place ?

Thanks.

Micky

with the standard set up the clutch pedal when fully pressed to the floor does'nt fully dis-engage the clutch.Regards,Micky

JimmyBoy

ahhh, thanks!

I was interested because I too am about to order an ap clutch with new quadrant & pedal and this topic just got me a bit concerned. Would be nice if there was metal ones available to the public.

the bolt on mine is right out (undone) and i have filed the quadrant down so that the bolt is pressing on a flat ssurface. hopefulyl it will last a bit longer this time, well until i can get a metal one anyway.

does any body want to maake me a metal one for some ŁŁŁ?

SafeChav

have you actually tried an AP clutch on a standard set up though? I bet you it would still disengage properly.

I may try fitting a white Mk6 quadrant to a Mk4 pedal with the auto adjuster still

Karlos G

iTrader: (4)

I tried it and fucked my gearbox after 30miles!! Could only select 3rd or neutral!!

Does not disengage properly at all!!

Had to do the Mk6 pedal mod..

Karlos

MarkXr

Don't think this would be a straight fit this way mate because the radius of the white "quadrant" is larger. (and you need the larger radius to get the clutch properly disengaged)

Micky

Yes safechav I did try it with a standard mark 4 clutch pedal set up,and I couldnt get the car into any gears!!!!!Regards,Micky

SafeChav

Only by 3mm

Ah right fair enough then

_P_

White quadrant + MK4 auto adjust pedal would fit together but the quadrant doesn't have teeth all the way on its circle so the quadrant will move freely when you use the clutch...

mitchrst

so is this just for the ap paddle clutch ?

because i have a helix 4 paddle and standard pedal and i find it bites very soon and hard to get in gear
