yey or ney?!

got a clutch from a cossie that was fitted in a car tranverse with an MTX75 box, hoping to run it on the zetec but dont know what diameter the cossie clutchs are?

its running a zetec flywheel with S2 ERST clutch and box. the input shaft on the box will physically fit the clutch, but not sure if the diamters are similar. banking on having to drill the clutch or flywheel but can anyone shed anymore light on the subject?

Garage19

The cossie clutch is physically to large to fit on the zetec flywheel and is also about 17mm thicker. It can't be done unless you use a one off flywheel.

I actually make a flywheel to mate a cossie clutch to a zetec but it is for a rwd format. See fudgeass's resto thread or this months fast ford for details.

to large diameter wise?!

thats a bastard, was hoping it could be redrilled and it would fit, seeing as it was run on a FWD gearbox before like....hmmmmmm

cheers mate

EDIT

having just thought about it, how the fuck can it be to big to fit on the flywheel diamter wise? the flywheel ring gears are normally no more than 10mm from the bellhousing in places anyway, and fwd and rwd bell housing cant be that much different in internal dimentions becase of the way they mount to the engine, its not posible for the rwd housing to be bigger than the distance between bolts in the engine block, do you see what im saying?! so if theyre the same size internally, and theres no room for a bigger flywheel, how can the clutch be bigger?!

or am i totally barking up the wrong tree here?! im assuming you mean diameter because thats the only think stopping it from mounting to the flywheel id imagine?!

Garage19

The cossie flywheel is physically bigger in diameter. The ring gear is a larger diameter.

There is not enough meat on the outside of the zetec to drill/tap holes for the cossie flywheel. They will break out the edge.

Trust me, I spent ages measuring all the dimensions on both and created cad drawings that have then be used in CNC machines to create flywheels.

and heres one doug made earlier







2wd cosworth size to fit a zetec crank.

still, no good for what you want

hmmmm, how big is the difference in diameter? is there no way of slotting/redrilling the holes in the clutch slightly furtter in, then redrilling the holes in flywheel slightly further out?! if the holes are far appart enough to break out the edge of the flywheel, then the holes are still ON the flywheel and the difference cant be THAT big....

sorry to seem like i wont take no for an answer but i cant be told "no it wont work" without seeing for myself

i cant remember if i binned my 2.0l zetec fly, ill go over the garage at the w/e and have a look and take pics to prove.

i know that the std zetec flys take a 220mm friction plate and the 2.0l flys take a 240mm plate

and the cossie one i just pulled out from under my desk is 240mm

but im not sure on the size of the covers.

but trust me, if doug says it cant be done, it cant!

he spent fooking ages measuring it all

xr-stu

hmmmmm

ive got an S2 ERST clutch on mine now which is 220mm, mine is on a 1.8 flywheel though as you cant use the 2.0 flywheel for one reason or another....i dont know the reason why but it might be then that the 2.0 fly is bigger than the 1.8 and to big to fit in a BC box, whereas theres no hassle fitting it in an MTX75 box, which would add up as the cossie engine/clutch was ran on an MTX75 box! if you get me?!

like i said, i have to see that it wont work myself, i cant just be told :blub

2.0l fly is deffo bigger than the 1.6/1.8 flys.

and yes you need a MTX box to run a 2.0l fly

sounds like im shit out of luck then i guess...

£300+ for a paddle clutch i supose

Ah, that makes sense with the gearboxes!

xr-stu

cant be alot in it though, the bellhousing bolts arnt that far from the edge of the actual bellhousing on the BC box, cant see there being that much room to make more space....well....gotta be 20mm i guess....
