Does a standard thrust bearing fit an OS GIKEN twin Plate? Or does there need to be a special one to be used only for the OS GIKEN pressure plate? Thanks guys. Ben
P.S Its a second hand Competition twin-plate clutch. Anything I should look at since it's second hand? How thick should the plates be before they need to be changed/resurfaced? Don't really know too much about twin plate clutches. Thanks.
Kyne's not quite correct here. It will work, but not correctly. Your clutch will more than likely not disengage as well with the stock bearing, as it won't contact the inner most point on the diaphram fingers. The OS Giken twin plates require a different throw out/release bearing. There is a nissan unit that is correct for use with the Twin plate OS Giken clutches but it IS NOT the same as the 300ZX bearing. It's actually from an old datson or something. Contact the australian OS Giken dealer and they can get you the correct bearing. If you want to get one a bit cheaper, go to your local NSK bearing dealer and ask for a Z TK40-1B2, this is the part number from my "proper" OS Giken bearing. You should also be aware that the throw out bearing carrier is ALSO different to the stock unit and you need to buy this from the OS Giken dealer, too.
$132 from otomoto for bearing and carrier. Would CBC sell the bearing and carrier? Cos otomoto don't sell the carrier separately. Or does anyone have a second hand carrier lying around in Sydney? Thanks. Ben
wear on pressure plates... Acording to the guy who is doing my clutch, the pressure plates min tolerance is 2.5mm. I also have a os giken twin plate with 3.5mm on each pressure plate. if you want it pm me. im not using it. ryan
here is what i've been told when i purchase mine in the states (second hand too): There is 3.7~3.9mm on the discs, 4.2mm is what they are speced at new and can be used down to 3.0mm.
Thanks for your help guys! I bought the clutch and a new genuine OS thrust bearing and carrier. Both plates have about 3.6~3.8mm on them. How long do you think the clutch will last? Thanks again. Ben
Why have a twin anyway? They are not nice to drive with, harsh on gear boxes, and expensive to buy and reco.
because they are fun to use, not so harsh on gear boxes depending on the type you buy, my one was much smoother than my friends 6 puck button clutch, they are reliable and they last a long time
Can do They can last a long time and so can 6 buttons which are much smoother to drive generally speaking, it does depend on installation and type of clutch both ways. Twin plates vary a lot and Twin Plate Nismo are very good.
I agree with method.... I'm sure anyone who has driven both can attest to the fact that twin disk designs are definitely more slippable and easier engaging than puck style single disks. It's simple physics... the more contact area you have in the clutch the more torque that will be soaked up by the disks before they engage. The whole idea of a puck style ceramic design is that they grab really suddenly - exactly the opposite of the twin disk.
exactly, people assume that 'twin plate' is racing style only and there is no sweet spot. There is a nice sweet spot with most of them and it will only engage hard if you want it to unlike a 3, 4 or 6 puck button clutch. Also, you are wasting half of the clutch with buttons because of their crappy design IMO and even at slow rpm they jolt your driveline badly if they are a serious clutch. I admit though, they do take a bit of getting use to, although that goes with just about any new clutch.
Yes and no 3 or 4 puck single are very grabby but 6 5 button are lots better and now can get 9 puck cushion button. We just fitted a 9 button to aGTR that had a twin plate and he now wants to keep the car as hated it with twin plate. We often turn people away form twins or convert if have twin or worse being a tripple unless they have the big power and need it and most don't. Lot's of happy customers. Lots fo GTR customers mainly blow up their gear boxes with twin plate clutches or triple plates.
