Car is a 1996 civic lxi,D15B, 5 speed. So I bought a used stock flywheel from the salvage yard. I also bought an exedy oem clutch kit from amazon. When I tried attaching the pressure plate to the flywheel, only one dowel pin would line up on the pressure plate. Any rotation I make doesnt line up all three dowels. And even if I could line them up, the 6 bolts that hold them together doesnt line up either. Also the new clutch disk is about 2mm bigger in diameter compared to the wear marks on the flywheel.

Could it be a wrong flywheel or wrong clutch?

The seller could have sent the wrong clutch or the salvage yard sold me the wrong flywheel. The flywheel was previously removed from a 97 civic,d15z4 according to the seller, but cant be sure until I see whats on my motor. I could not verify the flywheel until next week when I do my rear main seal and clutch.

Where's your old flywheel? Compare them? Could you have just resurfaced one that you already had?

As far as the pressure plate, keep turning it until it slips on?

The old flywheel is still on the car. Me and a friend will replace the rear main seal next week. Only then will I be able to compare the old flywheel. I needed to buy the flywheel earlier so that the job will be faster> I needed to remove some weight on the flywheel that I will swap in. Got the flywheel for 13$. I have already turned the pressure plate in every possible way and they just wont line up.

Something about that flywheel doesn't look right.

My guess is it's an '88 - '89 Civic flywheel. 1990 - 2011 are all the same for D-series and R-series, at least in terms of how the pressure plate bolts up. '06 - '11 might be different otherwise, but I'm pretty sure even those are exactly the same.

So the other day I went back to the salvage yard to get another flywheel thinking the flywheel was at fault. I found another EK with a d15b on it and flywheel was still attached. The flywheel was exactly the same as mine and the ek's pressure plate fits exactly on my flywheel. Now its 99% sure the cluth kit I got is not the correct one or 1% chance that D15B's have a different flywheel.

Has anybody have made a comparison before? How about those of you who ordered exedy clutch kits, is the part number the same as the one I ordered?

i never thought d15's ever came in any ek. i thought it was just the y5,y7 and y8 and those are all d16's. something isnt adding up only d series that was different was in 88 as noted above. you could always pull the dowel pins and bolt it on.

Around here, stock engine for 6th gen lxi is the D15Z4,5th gen is D15B2, 7th gen is D15Y2. My 96 lxi already had a swapped D15B. Only the VTI's or EX has a D16. Even if I remove all dowels, the 6 bolt holes doesn't match on flywheel and pressure plate.

08022 is for a d16 block. A simple check on exedy's website shows the manufacturers part number. All clutches and flywheels assembles for d16 blocks are the same. d15's use a different flywheel. Either find a USMD d16 block, or a d15 flywheel. They will not mate.

Oh and IIRC, a pressure plate can only mate to the flywheeel one way.

Uh, no. Not true at all. All '90+ D-series engines use the same clutch and flywheel. D15/D16/D17

'88 - '89 Civics used a smaller clutch and flywheel. '88 specifically uses a different transmission with a different spline count on the input shaft and consequently a different clutch disc. '89 is also a small disc, but transmission uses the same spline count as the newer larger style clutches.

There you have it. I was way off.

After more research and reading and visual inspection of my actual clutch, I have come to a conclusion.

1. Some Civic models from 1992 to 2005 have a flywheel that can only accept a 200mm clutch disc with 20 splines. The disc is almost identical to discs from 88-89 models with 21 splines. The pressure plate can be machined to accept a 210mm disc but the pressure plate doesn't have room for a bigger disc. There are bigger pressure plate that can accommodate 210mm discs but the bolt holes doesnt match the flywheel holes.

2. Flywheel and clutch kits for 92-05 D-series engines are interchangeable but not fully identical.

3. If somebody needs to fit a clutch kit from exedy or other clutches with the same specifications, a matching flywheel must be used.
