View Full Version : clutch disc direction

October 22nd, 2005, 01:04 PM
the side that stick out goes into the flywheel? I'm using a 6 puck so it's kinda hard to tell. plus it protrudes really far so I just want to make sure

aye mate

What kind of disc is it? It should have a sticker on it saying which side is the FW side.

IIRC the "snout" or goes towards the tranny so the splines can grab it.

MDC is correct. The snout goes towards the tranny side. It won't fit properly on the flywheel side. Won't work either, and would make someone very grumbly. :D

shit........ shit shit shit shit shit.... shit, the stocker had a "snout" facing the F/W so I figgered...... shit

lol.... ^ that sucks! yea... wont work that way ;)

yeah like everyone else has stated, the snout goed towards the tranny. the funny part, it will work to an extent if put in backwards. I had a guy about a year ago bring me a built up turbo that he had a SPEC (forgot what stage) clutch put in by a local Toyota dealer. After a short break-in period of easy driving, he started to get on it and it held fine up to 6psi then would totally let go. I pulled it apart and sure enough, it was in backwards. The sad pard here is that it was a Toyota dealer that put it in in the first place. (just another reason why I do all of my own work)

Bringin' this thread, back from the dead... I had the same question, since I've lost track of how it came assembled with the kit. Too expensive and will be a PITA to re-do, if I get it wrong.

So the raised section (top pic) goes towards the tranny, not the engine...right?

The flat/smooth side (bottom pic) goes to the flywheel/engine, right?

read people!

What's this reading business!?!?!? :biglaugh:

September 4th, 2007, 10:04 AM
what? research information for myself?!?!?! NEVER!

^^ Ha... Been looking at the TRSM for all of the tranny stuff this whole weekend and still kinda not sure. That's why I dragged this thread from the crypts (researching)...

I even put the throwout bearing hub together yesterday... which was new for me. I always thought it was a single piece :biglaugh:

Too risky of an item to guess at, by looking at the diagrams in the TRSM. I did not see anything in the TRSM which told me what to do with the 6-puck or give details about the orientation of the disk itself. Just wanting to be sure is all...:1zhelp:

Just not thge usual scenarios when using aftermarket stuff... for instance, there is a spacer plate between the stock flywheel and crank. It looks like it needs to be removed so that the new flywheel's teeth are located at the same spot as the stock one. Is that plate just a spacer and am I okay removing it? I looked in the TRSM, but could not find the answer ;-)

What symptons would you have if the clutch disc was installed backwards? (stock disc)

September 19th, 2007, 06:17 PM
clutch wouldn't disengage.

September 19th, 2007, 08:53 PM
Ok well mine won't disengage.

Stock flywheel, dual diaphragm pressure plate (local shop), with stock clutch disc for now (dont want to tune with a good disc).

Car off: can switch gears no problem so trans is good.

Car on: Can't go into any gear from Neutral. The clutch pedal has lots of pressure, travels to the floor smoothly. I can see the diaphragm flexing when the pedal is pressed. It wants to go into gear as when you try the car slightly rocks forward and a noise can be heard which sound like the clutch disengaging from the F/W. All the symptons of a reversed disc...

I was possitive the disc was in correctly but I unbolted the PP from the F/W and slid it forward to check the disc, sure enough it IS in correctly. (Sprung hub is facing the transmission).

OEM master/slave from an 1987 with a one piece SS braided line from master to slave (from Driftmotion).

Tomorrow I will try starting the car while in gear already to see what happens but after that I am lost.

too much clutch pedal freeplay?

improperly assembled throwout bearing assembly?

September 20th, 2007, 03:57 AM
entirely possible your clutch shop "overbent" the PP....making it impossible for it to disengage. i had one like that straight from SPEC....

September 20th, 2007, 07:02 AM
Should be alright, it was used with no issues on a 2JZ/R154 combo previously.
All I had them do was align the fingers of the diaphragm as they had shifted slightly from eachother.

Throwout bearing has been installed as per TSRM.

So I put the car into 1st gear with the engine off and turned the engine on. With the clutch pedal held down nothing out of the ordinary. If I start to release the pedal the car wants to move forward and if I take it out of gear I can't put it back in.

The problem was to much freeplay in the clutch pedal.
I adjusted to remove all free-play and it shifts now...
