ok here is the deal i replaced the clutch, pilot bearing, throw out bearing, and all the hydraulics. adjusted the clutch pedal but i still have nothing for engagement it seems now. it was working the first day then it quit just revs up. has a light weight flywheel i did re-install the spacers.
now i can sit in the drive engine running no clutch pedal pushed in at all shift through all the gears no grinds or anything. anyone have any ideas as to what the issue is? i can physically see the slave moving.

at this point i'm ready to take it to the shop and let them deal with it.

So if I translate this correctly, you can't shift when the engine is running. But when the engine is off you can shift just fine?

That usually means the pilot bearing is bad. You can easily destroy it when you reinstall the transmission if you use a bolt to pull the transmission on.

i can shift it fine its just not engaging at all. no movement or stalling from the car no grinding from the trans.

what i'm saying is to shift while its running i don't even need to push the clutch pedal.

Okay, so that could be clutch disk installed backwards, a badly out of adjustment pedal, or whatever this 'spacer' thing is that you say you reinstalled.

clutch disc is installed correctly as i made sure of this when putting it in. pedal was adjusted to spec already. i called centerforce about the flywheel they even said use the spacers and so did mazdatrix. it has to do with light weight flywheels being a single step and the stock ones being a 2 step.

Are you TII or N/A? It sounds to me like you are saying you put in a N/A flywheel and a TII clutch

n/a and its an na clutch otherwise the alignment tool would not have worked and the transmission would have not slid back together.

So what do you mean by this, do you have pics of your lightweight flywheel?

That flywheel.... It has a giant step. This is probably why your clutch isn't engaging. You most likely will have to machine the step down or get another flywheel. I bet if you remove your transmission, you will be able to free-spin your clutch disc.

A different clutch should also solve the problem. My friend's Espirt required machining for the centeforce clutch.

Edit: Just noticed. You used spacers? It already is spaced out, look at that step! That is most likely your problem. It's creating the same symptom of having too large of a step if your spacing out the pressure plate. Clutch is never going to engage.

here is the issue though this wasn't just installed this was installed with the prior clutch and worked fine. had a bad throw out bearing so i went to change that and found out the prior owner had installed two pilot bearings and a seal. this destroyed that clutch disc and flywheel needed to be resurfaced. it was all working fine then. according to centeforce i should be using the spacers still. they are the manufacture of the flywheel.

Either you have your clutch disc installed backwards or you have too much space in between the pressure plate and clutch disc. I had to use no spacer when installing my centerforce.

Did you have the spacers installed before when everything worked fine? If so, and you just machined the flywheel, the machining probably caused there to be too much space between the PP and clutch disc. You will need to remove the spacers to close the gap. This is all assuming you have the disc in the right orientation in the first place.

What clutch are you using specifically?

they were installed before and the parts of the metal that were embedded into the clutch disc as well as fraying at the edges of the disc.

There really isn't much that is going wrong besides the two things I listed. All your hydraulics are working properly. Problem is with clutch and PP, clutch is backwards or PP has too large gap causing it to not apply any pressure to clutch disc.

when you installed a centerforce flywheel was it on the rx7 or another vehicle?

jjcobm

It was on my FC. No spacer required and it was the dual friction surface one they sell (dual frction II? Something along those lines.)

i don't know what the prior owner had bought casue it was already installed and i found part of a centerforce sticker on the back called them with the numbers to confirm it was there product.

Ok, after our conversation. The N/A centerforce clutches use a spacer, the TII do not (thats what I used), so I take that back about not having to use the spacer. The OP doesn't have a centerforce clutch, he said he is using an exedy. If the excedy is built like the O.E. pressure plate, it won't require a spacer. If he added a spacer it will cause the issue. Now it's up to him to find out whether the clutch kit he has requires the spacer.
