ORC Single - Resurface flywheel/plate???

[upSLIDEdown]

So I hit gold when I popped the tranny off the back of my SR I just picked up. Got an ORC Single Plate clutch/lightweight flywheel with it. I pulled it off to check it out and it's got some burn spots/grooving in the flywheel and the plate. My first inclination is to resurface it, but since it's used, and the disc is used and they were worn/grooved together, would I be better off to leave it than to resurface?

[Phlip]

I would think it safe to use it as-is if they came together, having been used together.

Yeah, probably. I just want it to be fresh, that's why I wanted to resurface it. But a friend of mine said it may chatter more if I resurface it since the disc would still have some grooving in it and the plate/flywheel would be smooth.

why dont you resurface the flywheel and get a new disc?

[upSLIDEdown]

why dont you resurface the flywheel and get a new disc?

Other question is, can you resurface the plate, or do you have to buy another one? It's not flat on the back IIRC, so you might would have to mount to the flywheel upside down with nothing else first and get it resurfaced, then take it off and get the flywheel resurfaced... I don't have any first-hand experience with plate clutches like this.

[Dousan_PG]

nah u can resurface both
and get a new disc as well while ur at it.
thats ur best bet.

Hmm, wonder how much a disc would be. Who's the best to get ORC stuff from that could get me a disc?

[Dousan_PG]

rhdjapan is always good and reliable and fast

[upSLIDEdown]

How do I know which disc I need? I'm not sure which model clutch I have.

[Dousan_PG]

should be a part numbe ron it i bet
take a pic
pretty sure if its a single plate ORC
its probably ORC409

[upSLIDEdown]

In this pic, there's a small spring. I didn't see any springs when I took mine off the back of the motor...

LOL, damn. So the silent type has the little springs. That makes sense. Wonder if I can order just the springs and make mine silent. HAHA. I just checked RHDjapan and a new disc is $300. Ugh.

[IIIXziuR]

Yeah I have the same clutch lying around my garage.
Probably just going to resurface the Flywheel and Mid Plate and order a new clutch Disc from RHD Japan.

....I'm sure you already are going too but, while you're at it replace the T.O. Bearing and the Pilot Bushing for max fun.

The TO bearing looked different that the one in the tranny laying next to it. Anyone know why that would be?

[Dousan_PG]

yeah the single plate TOB are smaller.

[upSLIDEdown]

yeah the single plate TOB are smaller.

So how do I get a part number to order a TOB

EDIT: Holy shit, the Ogura TOB is $170 from RHDjapan

[Dousan_PG]

u entered the world of baller clutches
most single plates are about 800 bucks +

hence parts are a lot too

the thing w/ ORC is there is no us dealer i think??
maybe there is
but in RHD u will pay retail (MSRP)

hence higher prices.

[upSLIDEdown]

Ok, so this is the regular on RHDjapan's site
http://www.rhdjapan.com/images/product/14513/Image/Normal/Image5.jpg

And this is the silent type.

I swear the edge on my plate looks like the silent type, not solid like the regular one, but I didn't have any springs. I need to go double check and take pictures.

[s15specR]

where do you find a ORC 409D or a OS Giken TS2BD for a decent price ?

[Dousan_PG]

they might use the same clutch for all the cars
it might not necessarily be sr20det and such.

[upSLIDEdown]

I noticed. LOL

Well that blows.

EDIT: BTW, is it "Oh. Ar. See." or "OARK"? lol

[240trainee]

yep.

Thats why I plan on getting an exedy when I get one, better support.

But your more JDM, so you win, lol.

Just fucking throw that bitch in and see.

LOL, I got it with the engine man, I can't complain on that account. LOL Otherwise, it would probably be an Exedy, for the support. LOL I'm gonna have a local guy look at it today and see what he thinks. He resurfaces a lot of funny car clutches and stuff. He's a really good friend of ours too. =)

ORC stands for ogura racing clutch, ogura or orc for short. i think ogura is correctly pronounced (oh gu rah). the rah is kind of hard to type out its pronunciation but anyway correct me i'm im wrong. and if you dont want to deal with that clutch i'll take it off ur hands :)

[IIIXziuR]

ORC is like some of the best clutches.
Big Bucks but worth it, IMO.

The twin and triple disc clutches, now thats baller!
RHD Japan has an awesome selection of all.

um..

no one cares.

someone asked how to pronounce orc is so i explained...

I noticed. LOL


Well that blows.

i guess maybe i didnt explain well enough

Oh ar see, yes it is pronounced like

o.r.c.

I know wtf is stands for. LOL I just wasn't sure if it was actually used as a word, like "oark" or if it was just letters, like "Oh Ar See".

And I'm definitely keeping it. Just gotta decide if I wanna spend $300 on a disc or not. lol

[upSLIDEdown]

So after getting a friend to look at it (that used to resurface funny car clutches), I decided to get the flywheel and plate resurfaced. The plate was warped, so it was probably a good idea. It's not level, and smooth, as is the flywheel. I sent Aaron a PM, but someone else MAY know. The center of the clutch disc is offset. It sticks out on one side, but not the other. Does the side that protrudes go on side facing the engine, or the side facing the tranny?

[McRussellPants]

Silent type just springs the disk so it doesn't rattle with the pressure off of it.

If you resurface an assembely like that you need to take the pressure plate posts down the same amount or you'll lose holding pressure.

I've resurfaced on a worn disk, it doesn't matter, it'll just wear the disk image in to the flywheel fast and be back to where it was.

[upSLIDEdown]

????????????

Can you elaborate?

[McRussellPants]

posts space the pressure plate from the flywheel

move the flywheel surface away from the pressure plate you'll lose holding pressure.

gotta move the Pressure Plate closer to the flywheel surface to match.

[fliprayzin240sx]

If it came in the car as is, id leave it the fuck alone unless your changing to new plates. No point of resurfacing the flywheel if youre gonna re-use the same clutch plate and pressure plate. Clutch is broken in and they are grooved/mated. You resurface it, your gonna have to break it in again.

I just pulled my damn 409 out and rebuilt my OS Giken TS2B yesterday. Im in the breaking in process...500km cant come sooner so I can starty boosting back up to 1.2bar.

Anyways, if you need a rebuild kit for it, I can get it too. The shop I bought my rebuild kit from charges the retail price for it, same shit that RHDJapan charges. I may or may not save you some money using military shipping.

PS: If anybodys looking for a 409, I got one thats for sale thats only been used for roughly 5-6months.
Also the non-quiet type sounds crazy. When you first start the car, it makes this sound. Imagine in the movie when they pull a samurai sword out of its sheathing, thats what it exactly sounds like.

[upSLIDEdown]

Well i already got the flywheel and the floater plate resurfaced. Guess i need to go back and get the risers machined down a bit too. Damnit. Starting to look like i should have left it alone.

[fliprayzin240sx]

Yups, cuz now your gonna be eating meat out of your clutch plate.

Anybody looking for a 409? $350 shipped to the states for a 6 month old clutch that retails for over $900!!!

[upSLIDEdown]

Yups, cuz now your gonna be eating meat out of your clutch plate. What do you mean?

[Dousan_PG]

break in is easy

put it in 4th
and step on gas and brake (so car wont move)
do it for a bit
let it cool
and its set

straight from EXEDY on breaking in their single plates ;)

[fliprayzin240sx]

So how do you break in twins aaron? I just got back from a 300km jaunt to the northern tip of Oki and back...half the time i was stuck behind a fucking Kei-car thats doing 40 fucking clicks...
