Replacing the clutch

[Buckas]

hey guys, looking for a bit of help from people who know whats going on.

I've bought a custom clutch, made up for an evo 7-9. Its been put in the car and everything bolted back up together to discover it doesnt fit because the evo clutches are too thick. however, this is what was said in the kudos motor sport section for evo clutches, "
The late model evo kits are a direct replacement for the EC5 Galant/Legnum set-ups, and yes when installing a new clutch you should have your flywheel refaced."

now the mechanics are saying that it doesnt fit and that i should get another one that suits a legnum. is there anything they can do to make the current one work like other evo clutches? he said taking the car apart and taking more off the flywheel (4 to 5mm) could make it fit, but then i fork out for labour and theres no guarantee that thatll make it work, or that theres enough material on the flywheel to take that amount off.

so can anyone confirm if skimming more off the flywheel is the answer to making evo clutches fit?

thanks

also does anyone know if there is anyway to distinguish between an evo and legnum exedy clutch? the guys just chucked the new ones in and didnt look at it first so im wondering if theres any clear difference. i know that theyve bolted them up before cause they did mills_88's exedy SO for evos and it bolted up (makes some noises but drives).

this is just whats pissing me off cause hes saying its my fault for not really stressing to him its an evo clutch (swear i mustve mentioned it sometime), and that evo clutches simply dont fit and that i should buy a whole new clutch, when hes bolted exedy evo clutches up before anyway

The SO bolted straight up to my car no problems. No noises at all.

The only reason I get a noise now is because I screwed the springs on the disc when I broke the hollow shaft with a big launch at the drags. I have a new disc, just not the time to fit it yet. Car still drives fine.

Well thats at least a couple of guys with problems with their Evo clutches, sounds like a custom one is the way to go. I feel for you guys hope it all works out.

rebuilt stock ftw

evo disc combined with a rebiult vr4 cover plate and your tiptop

not only is is guaranteed to fit, its cheaper and does the same job

 

[Buckas]

so can anyone confirm, or let me know their thoughts, about whether or not the evo clutch will fit by taking more off the flywheel? Otherwise apparently im looking at an entirely new clutch

You need to get a spacer made up. Nick Mann in the UK sells them.

Some EVO 7-9 clutches, such as the stock ones fit ok if you use the clutch disc and the pressure plate.

So whats the mechanic saying exactly? That when the clutch is assembled and installed in the car it doesn't fit or that the clutch disk is too thick and isn't disengaging properly?

just clarifying that you are talking about installing an evo flywheel and evo clutch, you need spacers for the flywheel, NOT the clutch


to be honest buckas, there is no real fix that doesn't involve removing the gearbox again. depending how bad the squeal is, you could just drive it round till the clutch wears a groove into the gearbox housing and can freely spin.

thats upto you and how you feel about a groove ground into your gearbox lol

 

[bradc]

Yes, if you are using an EVO Flywheel you need to get a spacer installed.

 

[pu-11-me]

what clutch do you hav dawso?

Sorry for the late response.... It SEEMS to be a stock EVO but i'm sure, guess i'll find out when I pull it out!

 

[Buckas]

yeh i know that the gearbox has gotta come out again, im just trying to get all the info i can before it happens so we can sort out a solution. clutch wont disengage no.

brad i dont have an evo flywheel, its stock. could this clutch be made to fit in anyway? or am i looking at getting a new clutch

 

[unclepaulie]

get your clutch to disengage first before you remove the box. the selctor fork/pin/arm thingo might be jammed and that might be makin the sounds

hello folks,

I'm after confirmation on the correct seals and fluids to prepare for a clutch replacement:

Clutch kit I'm going for is the following:
Clutch: Exedy MBK-7223HD kit (pressure plate,disc,thrust bearing)
Flywheel: Machined

seals in question:

Crank rear main seal MD133317 (edit MD359158)
Cam seal x4 MD168055 (edit MD372536)
Crank front seal MD372536 (edit MD168055)
Man Gearbox Input Shaft Oil Seal . . MB936826
Man Gearbox Input Shaft Bearing . . MD746715 or NTN 6306 (from a bearing supplier)

fluids:
GL5 Differential fluids 75w-90 (rear only?)
GL4 Gearbox fluid 75w-90 2.2litre
GL5 Transfer case 75W-90 0.62litres

hoping i have all the seals and fluids covered....

thanks in advance.

 

[unclepaulie]

you needn't worry about cam seals for the clutch change...i didnt bother with any seal changes.

 

[kymbo]

or the crank front main seal. i'd change the rear main though as if that goes its a gearbox out job again

 

[godzilla]

fluids:
GL5 Differential fluids 75w-90 (rear only?) Yes.
GL4 Gearbox fluid 75w-90 2.7ltr
GL5 Transfer case 75W-90 0.62litres

hoping i have all the seals and fluids covered....

thanks in advance.

Just made a change to the gearbox fluid amount.

Interesting development guys, thought you'd like to know.

It seems as though mine was rubbing after-all. The really strange thing is that it never made a noise when it was first installed. It only made the noise after I broke the hollow shaft and we rebuilt the box and re-installed it. Nothing was out of place, however. Our install was completely correct. So I'm scratching my head.

So sadly, I can now count myself out of the very small 'no-issues' group and because I had no issues previously I had already bought my replacement cover. The car is at the mechanic's now and I need it driveable asap. What a PITA!

Apologies if I lead anyone astray with my info before, everything I said was true of my experience though.

 

[Buckas]

youuu bastard

all good, hope it gets all fixed nice and quick
