G'day,
just wondering whats the difference between clutches to suit imported models and our domestic market models?
i've got a clutch kit here that i got cheap, supposedly a heavy duty clutch to suit L4's, but after speaking to a distributor im told its to suit imported models, bluebirds and 200b SSS. the bearing looks different to my other two. but i dont have the car here so cant test fit it. its an R61N valeo clutch kit, i dont know jack sh*t about it, just got it cheap, and could only find 1 dealer, sunbury clutch and brake. thats who i spoke to.
so, anyone know if it'll fit in between a SSS stanza box and L20b?

The gearbox splines are all the same and so are the flywheels (between L20s and L18s etc). Maybe they are talking about the thickness of the clutches and the required thrust bearing carrier? Its a realy prick getting that stuff sorted out.

yeah your right dave.
i sat the clutch cover/pressure plate assembly on the flywheel and it sits nowhere near as high as the other shitty old unit i have. guess this is what he meant by the pressure plate being too 'low' any idea's on how i could rectify this, without having to buy a new clutch? maybe thats why the bearing appeared different. wish the car was here so i could have a look. i've got an old bearing somewhere just cant find it.
would the thrust bearing carriers be interchangeable and fix the problem?
and if so, anyone have one?

thanks,
dave w

You need to try different thrust bearing carriers. It would be bloody awesome if someone had a whole lot that they could measure and we could get a list so people could find out which one they need.

I've got no clue personally, sorry.

I'll have a look to see if I can find both types to take a photo.

Basically, there's two types of clutches.

The "thick" clutch needs a "thin" thrust bearing carrier, and the "thin" clutch need a "thick' carrier. And as you noted, the race itself is different. If you have a complete set (pressure plate, clutch plate and race) all you need is a thicker race carrier.

The whole assembly (from flywheel to clutch fork ) needs to be the same thickness. If you have two "thin" bits together, the clutch fork doesn't move far enough to disengage the clutch. If you have two "thick" bits, the clutch will potentially be permanently disengaged.

Hope that made sense - I'll have a look in the next few days to see what I can find in the shed.

awesome, thanks for that dave. makes perfect sense now. thats sort of how i'd pictured it. at least it narrows it down a bit, only being 2 types.
now just needa find out which cars have the 'thick' thrust bearing carrier.

oh and does anyone know anything about valeo clutches?
crap/average/good?
cant find much about them on the net.

Its been a while since I looked for one, but I think you'll have more luck looking in bluebirds, 200B, etc.

As I said, I'll have a look in the shed as I think my Z18 had one. If I can find a spare one, I'll send it your way. Don't hold your breath though - the shed is a bit of a mess after this weekends re-arrangement

To complicate matters there are 4 different thickness release bearing blocks. If you have an imported low pressure plate then the best bet is to try the bluebird or low plate 180B release block.

okay thanks for that Baz. wouldnt be able to by any chance tell me the dimensions of it, just so i know what to look for? i guess anything bigger than what i have now should do it? so say overall the clutch plate is 10-15mm lower then i want a release block 10-15mm thicker so the bearing sits further out?

i could end up being okay anyway, as i'm not even sure if this clutch was originally on the motor. it wasnt attahced when i got the engine, the guy just handed it to me along with lots of other parts/spares. anyway i'll try and pop in to the panel beater tomorrow and pull it off.
thanks,
dave w

Valeo, made in Korea? Had one in the Zed a few years ago, the ends of the fingers where the throwout bearing pushes on wore badly. The finger ends were soft enough to be filed easily, no warranty either.

May be better now of course, you did ask though

okay so i found oyt the heights of the two different pressure plates
52mm - is 1600, aus 180B and 200B and bluebirds
41mm - is stanza, imported 180B's, 200B SSS, and mk1 and mk2 bluebirds.
this was all according to the exedy catologue.

After another weekend of re-arranging the garage I came across my Z18 gearbox (complete with throwout race for a "thin" clutch) and thought of you

I'll try to remember to get measurements one night this week. If I find another spare carrier, I'll send it your way.

hehe thanks dave
yeah no rush or anything, but if you do find one it'd be great. i just got mine out from down at the panel beaters, its approx 41mm. so i assume the other one i require must be 52mm?

Well, you did say no rush

Only ever found the one carrier (Z18) in my shed when I was cleaning up months ago, but was under the parent's house today looking for lower control arms to extend the ones on my 1600, and found two bearing carriers there .

If you still need a carrier, let me know and I'll send one down to you.

200mm flywheels use the 510 T/O bearing and sleeve. Example Stock 510/610 and Roadster are pretty much the same excpt the Roadster has 650KG instead of 350KG(stock 510)

I had a Centerforce clutch which which was just a repainted GOLD Daiken and a made in Korea disc. Seems OK but will get the jap disc next time.
