I just bought a 88 crx with a DOHC ZC swap in it. Soon after i bought it, i had to replace the clutch because it was pretty much gone. first i got a 88 crx si clutch kit, the pressure plate bolted up fine but we soon realized that the disc was too big for the transmission, we ordered a 94 disc for the 94 transmission which is bolted to the zc block. Well first we tried using the new pressure plate, since it bolted up just fine and we put it all back together, tried to start it and all it did was make a really loud cranking noise for a sec. we were told its probably the press plate, so we took it all apart again and put the old pressure plate on with the 94 clutch disc. we put it back together and tried to start it up again, it still made a not so loud of a cranking noise. we noticed when we took it off to change the plates that the disc had been nicked as well as the plate being scratched. we think now that the clutch disc isn't right. DOES ANYONE KNOW WHAT KIND OF CLUTCH DISC I NEED?

 

sounds like it may not have the 88 transmission - i don't think it has a 94 transmission as the EG transmissions won't work in the EF car - if the 88 pressure plate bolted up, then it must have the 88-89 flywheel - count the splines on the transmission input shaft - if it has 21 splines, then the transmission is 88 and you need the 88 Si clutch disc - if it has 20 splines, then the transmission is 89-91 and you need the 89 Si clutch disc - the 90-00 clutch will only work if it has 90-00 flywheel - the 88-89 pressure plate will not bolt to the 90-00 flywheel

 

its not the standard EF engine or tranny, it has a JDM ZC DOHC swap in it and when i bought the car the previous owner was taking out the tranny in it, which he said the syncros had gone out, he said he was bolting up a tranny from a 94 civic which bolted up to the 1.6 modeled ZC blcok just fine. he didnt tell me what the old tranny was or what flywheel clutch disc press plate was from either.

 

again, it is not a 94 transmission, as 94 transmissions will not bolt into the EF chassis and also have a hydraulic actuated clutch (the EF has a cable actuated clutch), but, even if it was a 94, it would still have a 20 spline input shaft, which is the only thing that matters, as far as the transmission is concerned - the type of engine does not matter as long as it is D-series - since your 88 pressure plate bolted to the flywheel, <U>the flywheel has to be 88 or 89</U> - since the flywheel is 88-89, then the only thing that controls which disc you need is the number of splines on the transmission input shaft where it goes into the clutch disc - 21 splines=88 clutch - 20 splines=89 clutch

 

well i know the 88 clutch disc doesn't work but the only way i knew that was becuase the disc was too big for the shaft to fit properly, would the 89 be smaller because of the difference in splines? if the 89 diameter of the trans. shaft is the same size just different number of splines as the 88 then i dont think the clutch disc for the 89 would work either. the disc for a 94 fits on my tranny but i believe the outer diameter of the disc is too big around, it rubs really badly and is the only reason i cant start my car. also the 88 pressure plate rubbed the inside of the tranny and made the overall sound of the car trying to crank up worse than it is now with the old plate that was on it to begin with.

 

Match the clutch/pressure plate with the transmission. Think about it logically, they both have to go on the input shaft of the transmission. If you have an 88 trans, buy a kit for an 88. If its a 89-91 buy it for a 89-91. If you're unsure count the splines. I think 88's have less I can't remember. You can find that out if you search.

 

I have an 89 CRX SI with the ZC, used the SI tranny... I believe it has 20 splines on it (can't remember, haven't had to change the clutch or tranny in over 3 years)

Just get yourself an 89 SI transmission

 

My old disc has 20, which means its an 89? and the kit that i first bought was an 88 and it has 21 so i need an 89 disc rather than the 88 kit that i bought, should the 88 pressure plate work with a 89 clutch disc? i don't believe so because it had scratches on it from trying to start with it but i need to make sure.

DOES ANY BODY HAVE OR KNOW WHERE I CAN GET AN 89 CLUTCH DISC AND POSSIBLY A PRESS. PLATE????

 

anybody?

 

ya i had a 91 si with a zc in it and we just used the si trans and it worked fine.

</TD></TR></TABLE>88 and 89 used 2 different size clutches based on the model of the car - some had 190mm diameter clutch and some had 200mm diameter clutch - they both used the same flywheel - your clutch disc diameter needs to match the pressure plate diameter

 

i appreciate all the help, i gotta get to the garage and measure the old one to make sure cause i found a good site where i can get a clutch and they have the measurements for theirs and i can make sure it matches before i buy this time.

 

Ok now i have another problem, the nut on the passenger side axle, holding it completly to the hub is stripped both ways. Its an 88 crx HF model with an 89 tranny bolted to a DOHC ZC, I tried the 88 1.6 L axle but the spline shaft didn't fit, should i try a 1.5 L axle or is there even a difference? any suggestions?

bump

 

its the pressure plate hitting an alan key kinda bolt in the inner housing of the tranny. i had that happen, if you look carefully you should be able to see where it contacts. its only a few mm's i carefully ground down the head of the bolt in the tranny housing (NOT TOO MUCH) til it cleared, and when i swapped for a new tranny i forgot to grind it down again, it knicked just a bit and i was too lazy to take it off again, so i just drove it carefully for a while and let it wear down. now it's fine (that's only because i am swapping it all out soon and just needed it to run for now) i wouldnt recommend letting it wear down on it's own if that's your good setup.

hope i helped

if u would read it all you would see its the clutch itself i was having a problem with, i have now fixed the problem i was having, my clutch disc was too big in diameter, it was a 94 and i had an 88-89 flywheel and an 89 pressure plate and the clutch rubbed the press. plate and the flywheel. now i got an 89 clutch kit that i just put it and it runs fine, but my problem now is that my passenger side axel nut and shaft are stripped out and i need a new one, (i tried a new nut and the axel just stripped it out too). i have an 89 si tranny with most likely hf hubs in an 88 hf body. the axel i bought was for a 1.6 L, do i need one for a 1.5 L ?
