ORC Clutch and Flywheel

[aaronng]

Thanks, I have heard the clutch type LSD required to change oil more often.

Hi all need an advise.
do you think is it good to have a used TSX final drive (4.764) on CL9? other option for me is to buy a new set of spoon FD (5.1) or Mfactory FD (5.48?).
The most expensive is the Mfactory, over a thousand shipped. Spoon is about 780 and the used TSX cost 400.

what you guys think?
Thanks

If you buy the TSX final drive, make sure you get the matching speed gear for it.

is it good to have stainless steel clutch hose install? Thanks

does someone know which workshop is the best for install clutch & flywheels for Honda Euro in Perth WA?
Called Tony Flood, it is too big job for him alone. and I found a place called S&G Gearbox Exchange (Ford & Holden). www.sggearbox.com.au Are they good?

Thanks

need help!
I installed this ORC clutch at 21,000km in May-June last year.

Last month or so the clutch started to make whining noise. Similar noise when car is in reverse, but it is in first gear after clutch is released and engaged.

Then last week I just experienced clutch slipping! I was driving spiritedly, going from 2nd and flooring it down to 3rd and 4th. Clutch slipped all the way in 3rd gear and 4th gear for the first time. By slipping I mean rev went up but speed was not going anywhere. Even I tried to set the cruise control on, by putting accel button on the steering wheel, the car just revs up and not going any faster.

Today I was trying to overtake a tram, at around 40km/h, I couldn't even do it! When driving the car now I have to be careful with the throttle. Any gear I am in, even though gear is already engaged in, if I apply throttle a bit too much (not even near flooring), the car revs up quick and speed isn't increasing.

Car has only done 33,500 kms at the moment (12,500 on this ORC clutch) and it has only been one year and five months since I got the clutch installed. Why is it gone this quick? I never used engine brake at all or riding the clutch to slow down the car. I think with my driving style, I only need to ride the clutch a bit more to take off smoothly in the city etc. Is my clutch on the way out? Is it something to do with ORC clutch plate being metal?

I am thinking of getting Exedy organic clutch that comes with pressure plate, clutch plate and release bearing. I think this will fit the DC5 ORC flywheel I have? Any other better option? I don't think ORC offer overhauling kits anymore and I doubt I can get only clutch plate for it.

Thanks very much for anyone that will help. Rep points will be given too

Have you tried adjusting the friction point and doing a simple clutch fluid swap?

I don't know how you drive but the clutch could be engaging on an angle, I don't think the release bearing contributes to that though.

As far as a replacement clutch, any brand clutch made for K20 or DC5R would fit the DC5 flywheel.

Hey thanks for the quick reply!
Haven't tried adjusting the friction point or clutch fluid swap. But I feel that my friction point hasn't changed. My car has had problems with creaking clutch pedal/master cylinder changed etc. I had been fixed but I doubt it is that that is causing the clutch wearing this quick. And it is supposed to be performance/metal clutch too so I didn't think or expect it to wear out only 12,500kms?
Gears can still get in fine with no problem. Clutch pedal still feels very hard like it used to be since it was first installed. But the bite has gone almost completely. Feels like it is almost not biting at all..

[integral90]

The whole point of a sports clutch is that it grabs harder than a normal one, so you can't drive it like a normal clutch. I know with my Exedy sports one if I ease off from a stop like I did with the stock clutch it burns out (AND YOU CAN SMELL IT BADLY) straight away.

You've got the be a lot quicker getting on and off the clutch with a sports one, of course, I don't know if you do that or not :P

I can only get on and off the clutch quickly if I'm not driving in Melbourne city traffic. But ORC clutch is metal though, I had never had it burning. Don't think metal clutch can get burnt? I really like how the pressure plate is very very firm. So say if I swap to exedy sports organic clutch plate, pressure plate and release bearing, is the car will be more easy to drive? Given that I still use the DC5 ORC lighten flywheel (3.8kilo from memory). Seems like some issues just pops up every time I get something fixed

[integral90]

The Exedy Sports feels almost identical to the stock clutch in friction point and firmness. I am a little bias when I say that because my car had an incredibly stiff OEM clutch (Aaron felt it). It just bites much harder, which is really nice. That said; when you're driving it you can almost feel that it's a smaller clutch dealing with a bigger, heavier car than it was necessarily designed for. It doesn't slip when fully engaged, but if you give it too much gas before you've almost completely taken your foot off it will slip.

It is really nice though, firm with a LOT of feedback. I can drive the car seamlessly smooth quite easily with it. Haven't driven the ORC, but I assume it's smoother than that

Did you replace the pressure plate when you changed the clutch? If you didn't, then your pressure plate could be worn or damaged, seeing that your friction point has not moved upwards and you have that whining sound. Does the whining sound go away when you press the clutch pedal down?

[kitbkk]

Yes Aaron, the whole clutch combo was changed. This includes the clutch pressure plate, clutch plate, flywheel and release bearing.

Normally, with clutch worn out, does the friction point move upwards?

The whining noise goes away when I press the clutch pedal down. But it is very loud, both in first and reverse.

I just got a PM from JDMYARD, unfortunately the DC5 exedy sports organic clutch will not work with ORC flywheel I have. Though they can order in ORC replacement clutch plate. Quite expensive for just a clutch plate though. Yonas stated in the PM saying they had abused their ORC clutch with drags and circuit use. And they had been using it over 3 years!

Well, I can't make decision, whether to just buy the ORC replacement clutch plate or get exedy sports organic combo and flywheel.
Option 1 will cost me around $600 (only clutch plate alone, pressure plate and others parts have to be reused) but I am afraid it will only last about 12,500kms again in the future. Then I will have to pay more for installation.
Option 2 should be around $600 for clutch kit and $4-500 for DC5 flywheel? So this $4-500 for the flywheel makes it more expensive than option 1 but I think it will be better for daily driving and city drive.

At the moment I am leaning towards option 1 and see if I can improve my driving style. In the city traffic, I think I am not fast enough for getting the clutch ON/OFF. I apply gas fist to around 1-2k rpm then release the clutch very slowly to get the car moving a bit then release the whole thing. I think this is what caused the premature wear out?? I though only once in a while do flat shift but that is only say once in two weeks. I never use clutch to do engine brake however..

Long post I know. Thanks heaps Aaron and integral90. And others for reading too.

Yeah, that is probably what wears it out quickly. Especially if you do that a lot on hill starts. I know of someone who shifts gear by holding the clutch pedal halfway for about 0.5 seconds to smoothen it out. His OEM clutch died in 10,000km. 0.5 seconds is nothing, but it wears out quick. And for your ORC which is a different formulation, it could be less forgiving to releasing the clutch slowly. Why are you holding revs at up to 2k though? If you were releasing the clutch slowly, 1000-1500 rpm would be enough.
