Title: Twin plate clutch to single plate advice!!
Post by: Chriszx on June 22, 2007, 04:21:41 PM
Hey peeps,
Not posted much on here since buying my Rex (Gurj\'s old purple T78 from a chap on the IOW), mainly coz two weeks afta buying it the clutch is fvcked. Not overly happy but that\'s the luck of the draw I guess.
Anyway, it\'s got an OS Giken twin plate in at the mo which I know is rebuildable but I\'m not going to bother doing, so Iv\'e ordered an Exedy hyper single from Lisa @ shy auto. My question is - knowing that the OS Giken is a push type clutch do I need anything else to make the Exedy single plate fit??

Any advice would be greatly appreciated :)
Thanks in advance,
Chris :guinness :guinness

you will needed the Exedy Flywheel as well?, have you bought this as well as the OS Giken has a specific flywheel which incorporates the Clutch plates basket. The OS Giken rebuild kits are approx 440 inc vat from RB Motorsport and vastly superior to the Exedy single plate stuff

I\'ve ordered the clutch flywheel combo. It\'s more of a time scale thing for not rebuilding the OS Giken clutch. I need to fit the Rex clutch so I can sell my 300ZX which I\'m using as a daily driver until the Rex is fixed. Also not sure which OS clutch is in it :Hammer
 
So, do I need anything else or will the Exedy single plate go in??

I.E do I need a pull type fork to make the new clutch fit??

Any advice would be greatly appreciated :)

Yes, if your new clutch is pull type you\'ll need to change the release mech bolted to the box back to the stock setup.

Thanks mate, so what parts would that involve, would you know??

I\'ve just pulled the giken mech from my box, but i can\'t quite remember what a stock one looks like. I think you\'ll need the collar that sits around the input shaft and the release bearing moves on, and the release fork with pivot mech. Don\'t have one tho, I\'m afraid.

RB usually have the rebuild kits in stock, then its a case of just swapping old bits for new bits...

It does sound like a plan but I dont know what grade/model OS Giken Ive got in the Rex :2Confused

To swap from an OS giken twin plate to a pull type exedy single you need to remove the push converter from the gearbox and get a standard pull type mechanism from a stock gearbox, the job is fairly simple, so don\' worry too much

I spoke to RB and they were very helpful. You can work out what you\'ve got just by looking at it, measuring a few things, then ringing them - that\'s all I had to do.

Nice one, not sure wot to do now tho coz the exedy unit is paid for & on its way. Think i\'m commited to going the single plate route now but thanks for the advice
Cheers, Chris.

Hi Chris,

Clutch was completely fine when i had the car so very sorry to hear of your woes buddy, i only sold the car as wanted a change nothing was wrong with it that i knew of.

As for the clutch make sure the Single plated one can handle the power output, does it have a guideline as to power capability as you dont want a weaker clutch as wont last as long. On the good side though at least it will be better at pulling off than the twin plate version,

Gurj :cool

Hey Gurj,
It\'s just one of those things. The car is still amazing even sitting on my drive, just want to make sure I get it back on the road in time for Rotorstock. I think the Hyper single should be fine for that kind of power as from reading other threads it seems a few guys are running 400+ horses with the same unit. By the way I\'ve also ordered a Scoot carbon bonnet from Lisa as well so it should look awesome come August :Thumbsup!
Cheers, Chris

Hi Chris,

I actually placed a carbon bonnet on the car a while ago but the carbon colouring didn\'t suit the paintwork as far as me and the wife could tell, if you match the paint up and get it resprayed it would look better mate ??


Here you go have a look and see what you think Chris, found my very old thread about the bonnet : http://www.mazdarotaryclub.com/forums/showthread.php?t=24874&highlight=carbon+bonnet
