Oops sorry, didn't see there already was a third page on this thread. Just one day away from the computer and hey..........

Very crappy about those AP guys not to answer any questions. But hey we've already bought the clutch.

Dave Y, please keep us informed about those metal quadrants, I'm in real need of one!!! Would be superb if you can get them made up.

 

well i had an e-mail back from AP Racing.....

here is the mail i sent

hello,



i am just emailing to write about the fitting of clutches to the Ford Escort Range for 1986 onwards.



I myself bought and fitted one of your Organic Fast Road clutches for my 1990 Ford Escort RS Turbo in June 2006 and as recommended by your website I fitted the adjustable pedal, improved quadrant and a new clutch cable to optimize clutch release in light of the higher release loads as per the guide shown on the following web page. http://www.apracing.com/roadcar/clutch/epmods.htm

However yesterday while trying to reverse off my drive the 'improved' quadrant snapped releasing the clutch and my car locked into reverse which then hit a kerb before i had the chance to try and stall the car to make it stop.

It would seem that the recommendation made by AP racing is false as it clearly cannot cope with the higher release loads.

I also appears that i am not alone in this probleem as can be seen by this link to passionford website https://passionford.com/forum/viewto...asc&highlight=

Many other Ford Escort owners have suffered from your recommendation failing leaving some stranded with no use of the clutch pedal!

Some owners have replaced the quadrant suggested by AP Racing with a metal alternative and have reported good results, this can also be seen in the link to the passionford webpage.

It does not say anywehre on the recommendation page that the quadrant is a serviceable item with a life expectancy as short as 1000 miles in some cases.

Perhaps you could produce metal quadrants to stop this problem happening in future or at least edit your website warning potential buyers that this such problem can occur.

If you were to produce metal alternatives then there would be a great interest for them myself included, i could generate at least a further 10 sales alone from people who have also experienced similar failures when using your products.

I have to admit i have been very pleased with the functioning and the quality of all the AP Racing products i have used so far but this has cast a bad view of the company in my eyes especially since it seems to be such a common problem.

I anticipate your reply,

Regards,

David Holmes

 

the reply......

Dear Mr. Holmes



AP Racing has not received any other reports to date with regards to this Ford clutch quadrant component failing in operation when used with AP Racing uprated clutches; either from our official distributors, of which two are Ford tuning specialist, or from the end user!



Quadrant & Pedal data sheet # P14.039.

This was added to the AP Racing Escort Ř220mm pressure plates from June 1998. With a recommendation to fit the latest Ford quadrant and manual adjust pedal introduced onto the Escort range from 1995 on. The information being that this new set up alleviated first & reverse gear engagement problems experience on some standard cars built prior to this date. APR suggested using this new set up on the RS because if the standard clutch was having disengagement issues then AP Racings uprated unit based on the standard Ford / Borg & Beck unit, could also suffer clutch release problems in some cases. Until this quadrant with its increased 55mm radius became available we had received reports from owners experiencing release issues, this latest Ford component offered a fairly straight forward cure. However if the APR clutch released OK without the mod then there was no need to add it.



Increased pedal loads.

These are higher on the uprated unit but that’s the trade off when using a stronger diaphragm spring allowing for a higher torque to be transmitted. The quadrant mod was not required because of the higher pedal load, but due the higher clamp load / torque unit requiring approx 2mm more of release bearing travel to disengage the clutch over the standard unit.



Photo attachment from the thread provided by yourself.

This quadrant has failed in the same way as your own, but note that it has not had the modification added! Our local Ford Dealer supplies up to 8off part # 1029013 per week into the spares market, so we could deduce from this that they require periodic replacement on standard Escorts; although I’m not suggesting after 1000 miles use!

The Escort Cosworth RS also uses the same quadrant design. AP Racing has supplied thousands of Ř240mm uprated clutches into this market for both competition and road use since its launch in 1991. These larger clutches have the same direct release load (1800N) as the RS Turbo clutch. Again we have had no reports back of any quadrant failures on the Cosworth!

Your quadrant produced in metal is obviously a good solution, but manufacturing costs would be too high for APR to produce when it involves such small numbers.

FYI



APR Ř220mm pressure plates that may require the quadrant mod involves the following part numbers: -

Pressure plate part #

CP3560-1

Used in Clutch kits

CP2000-8

CP2015-8

Pressure plate part #

CP3560-2

Used in clutch kit

CP2000-35



APR Ř220mm clutch kit with standard torque capacity (142lbft), not requiring pedal mods.

CP2000-15

 

See, the first major problem we have here, is, the person who wrote that email doesn't even know what they are going on about.

A standard ERST quadrant is BLACK, and is 55mm.

The uprated one they suggest fitting is WHITE and is 58mm.

What a bunch of, and i quote "Fucking Jokers"

 

And for those of you who probably think im chatting shit

 

Calm down dear its just a commercial you replied to my first post and now you must take responsibility

Perhaps i should explain If you look at the two quadrant types the early one is thicker around the pivot hole, whereas the later one is thinner and possibly weaker, so it could be a reason why theyre breaking at that point After you mod the later one they look the same so i was thinking of fitting the early one to the mk5 pedal as it'll be stronger maybe If you read my first post properly you would seen the reason why im changing it

Okay so the gaffa tape idea a bit dodgy but why not put the car back together and get it out to the shows or something, you'll want to keep it and work on it more if its on the road, who cares if its tatty

dave_y keep us posted on the metal quandrants

 

i wouldnt put it on show down the scrappy in its current state let alone any shows

 

interesting reading this. My old s2 had a AP clutch with the recommended pedal mod, but the last owner had done this so i had nothing to compare it to, although it seemed to change gear fine as far as i can remember.

my current s2 hasnt got the pedal mod, is comletely standard. Ive put the engine in from my grey one but havent got car on road yet so i will have to wait and see.

but, im interested in the metal quadrant idea if anyone is gona get some made or could make one. One silly question......... metal ones that people have made up, i notice they dont have any teeth on them, does this matter? what do the teeth actually do as per standard quadrant

 

well this is gona get ugly


Mate will be but in 2 weeks from his honey moon so if your in essex i will get a deal sorted to get some of these made!

 

nice work mate, keep us posted

 

Teeth are only used when you have the self adjusting pawl

 

It seems the topic goes on in a new one.

hi all i have a fiesta si, and have been posting alot on fiestaturbo.com and fiesta-si.com and have still got the si but now have like my name says a mk4 escort estate, with all s2 running gear engine gearbox brakes etc so its basically an rs turbo in an estate shell, i have had it for a couple of months and was driving it for a few days before various things went wrong, first i found the turbo wasn't bolted on properly to the rest of the exhaust and that the guy who had it before me had just put some putty round to get it through the mot, so i got some bolts and sorted that, then a few days later the radiator went pop so i got a new radtec one and put that on, then the core plug under the cam on the side of the block went pop so i got my mate at a cost of 250quid to repair that, now i have joined this site just to find people who have been doing the mk5 quadrant and adjustable pedal mod and yay i have found some, i have cut 10 teeth off like ap racing say to do and then i looked under the dash to have a look at how i would replace it but i have no idea please someone help also would anyone make me a metal one for some ŁŁŁ cheers

 

Best bet for you i would say is to grab a haynes manual and follow the guide in there.

Not a lot different about the fitting process

 

ye id like to no that as iv got an s1 box with ap clutch in my rsi and its reli high aswell but iv only just had the car so havent had time to look why yet?
thx mart

 

mine is on its way out
