Hi Monte

From what you describe i would be sure something is in the wrong way as it sounds exactly like the issue i had when i did exactly that. I know you said you checked it but thats where i would look if all the hydraulics are working

pdtaylor18 · February 14, 2011, 08:54:53 PM

Totally agree and sounds like a classic plate in the wrong way around, its really worth that double check...........gearbox off I guess!!

Sounds like the parts for your clutch are in wrong,
All parts of you clutch should have a paint mark or scribed line to ensure correct alinement. One part or more not in the correct line will cause the problem you describe. Been there lol.

i havent been able to find any good info from os giken that shows what way they plates go in. we could only find others pics or builds: someone installed one on a fd and said the spline area on the clutchs stick out one way and not the other. install clutch discs with splines pointing towards the rear. so thats how i have them. but before i installed the clutch we tried rearranging the plates and floater. i have it arranged the only way it seemed to make sense.

every time i used a clutch alignment tool so that splines are aligned. since i havent been able to find any other info on how to arrange the discs ive left them where they sit. dont really want to start swapn stuff around and chance breaking something permanently, with my luck.

but i too agree that something isnt right. ive been searching and havent found much anything else. this is really doing my head in, so thats why i finally came to everyone here. dont suppose anyone has any hints as to how or where to find install info

thanks again for all the help

Give RB motor sport a ring, I\'m sure they will help you out.

on some clutches, they actually have \'flywheel\' stamped on the plates and that side goes towards the flywheel, not sure if OS stuff has it on.

called rb motor sport today. very very helpful steve was. i asked steve if he could help me figure out the correct arrangement of the clutch discs and he did just that. he was nice enough to email me the install instructions and since they are not that clear, he also took a pic of the correct order of discs and floater.

by that pic, i have 1 disc wrong. hoping i can get to the shop after work tomorrow and hopefully drive the 7 home. ill let everyone know what happens

thanks again for all the help in troubleshooting this issue

i reckon your slave cylinder seals are kaput still

pdtaylor18 · February 17, 2011, 06:31:56 PM

Is this the White RX you have? That has been sat rather a long time.

Either way with the clutch fitted correctly whether the slave is working or not it still should not grind like it is. Is it still grinding? When you took it apart did you spot where the grinding was taking place?
You sure this is the correct clutch for the car.

yep sure is the white fc pete. had it on the road for maybe 5 wks before i started this twin plate mess. yeah she still is grinding. we didnt notice anything that caught our eye. last time we dropped the gearbox i did a quick look around then swapped the disc and put it all back to together. the clutch was in a running fc in the states. got it from a friend in idaho.he swapped it out just to go a diff route.

so i found my old flywheel and bought a clutch from jimmy z\'s, just the exedy single plate with pressure plate and release bearing. should have that tomorrow and will be putting it in on sat. so will find out if its the twins or not. i know everything worked with a stock configuration but doesnt with the twins. so will see what happens when i put stock stuff back in...........

will let everyone know whats going on hopefully saturday

May be a silly question, is it a pull type. Or a push type. Just a thought.

Keith

monterx7 · February 17, 2011, 10:34:36 PM

the twins are a push type...for fc\'s

Quote from: monterx7;743440so i found my old flywheel and bought a clutch from jimmy z\'s,

Ah, so the flywheel didn\'t come with the clutch - are you sure they are compatible? The flywheel only need be a few thou too thick for you to get the problems you describe.
