Car = 91 Si
Trans = 89 DX
Axels = 91 Si
Flywheel = 90/91 Si?
Clutch/PP/TO = 90/91 DX

This is the second I've completely dropped the motor and trans to replace this clutch. I even replaced all the clutch components such as TO bearing,Input Shaft Bearing, pressure plate, and disk. Flywheel was resurfaced and everything was put together out of the car and went together fine. Put the car all back together and the car wont' engage. For the life of me I cannot figure this out.

Gears are easy to move into, weather the car be on or off. I start the car, put it into gear and let the clutch out. Nothing happens, in Reverse/5th/4th it almost sounds like its gonna engage. I can feel pressure changes in the peddle when moving to those gears. Also, I can change into 1-4 without using the clutch.

Only problem I can see is the passenger side axel is not fully entering the differential. Could this be the problem? I didn't think the axels were diff from a 89 DX Trans and 91 Si Hubs. Can anyone please shed some more light on this subject, I've poured my last 3 checks into this car and even got a payday advance I was so desperate *Cries* - Darrell

 

The axles aren't the problem right now. You shouldn't be able to shift thru those gears without the clutch with the car running. I know different year crx's have different number of splines on the input shaft. The flywheel goes right onto the input shaft? The 90-91 have a bigger flywheel than the 88-89 too. It sounds like your clutch isn't even getting close to the flywheel.

 

When you shift gears, can you hear the gears clunking in the tranny?

 

So then most likely the flywheel is diff? The problem is the car came with this fly and it was already swapped. No clue what year it is, I assume I would have to measure it? But this is more than likely the problem? Any other ideas? Just don't wanna drop this tranny 3 times and find out I need something else.. - Darrell

Only in 4th/5th/Rev.

Yeah thanks, I tried tightend the cable to hell and it seemed to make a difference, but still will not spin those hubs. I think sporkcrx might be right and that goddamn flywheel is the incorrect one. Man I am so deep in the hole on this car its hilarious. - Darrell

 

No I'm not sure if it's the flywheel, I mean it might be...but I dont see how the clutch wouldn't be grabbing it. Did you replace the input shaft bearing yourself? Did you have to crack open the tranny to do it?

 

I have an idea.

Put it in the air, put it in gear (try a few of em, 1st, 2nd, 4th, etc.) and see if you can spin the axle or the wheel in reverse. This will let us know if the tranny is going into gear. If it is, then it narrows it down to the clutch area.

edit: make sure the wheels spin freely in neutral too...just for the hell of it.

 

Hmmm my post went byebye i guess. Here is my 1st post:

Yeah if the flywheel and clutch are not engaging then there is no way of transferring power obviously. I guess you may have to drop the trans again for the fourth time and measure the flywheel.

Now this is strange because the first time the tranny was put back together it did spin the hubs but the tran and engine were'nt flush and it destroyed the clutch disk. This time, everything is flush and its not spinning the hubs at all. If you lift the bar that controls the TO bearing[can't remember the name atm] you can feel the TO bearing pushing against the Pressure plate fingers and spinning. - Darrell

BTW thanks for the fast replies and ideas, helping me alot, for honda-tech.com

 

ah hah, I think I got it.

I bet the splines on the input shaft are going past the splines on the flywheel.

OMFG, I told this mechanic I asked about that that sounds like the problem. He said its possible but VERY unlikely. Well I always have been one to override statistics. Now, to fix this problem, what am I going to have to do? Its gotta be that damn flywheel right??? lol, this is like an intense game of clue :D - Darrell

 

But, how could it pass them? Isn't the flywheel differences in the surface area, not the width? Argh, so confused t_t. - Darrell

 

That's the only thing I can think of is the flywheel being too thick. I'm not sure if that pp will bolt to the older flywheel though.

 

Does anyone know if the 89-91 Clutchs are the same part #? How about the 89-91 Flywheels? Is the difference in the flywheels between years only the outter diameter (200 vs 212) or is the width? There is a reason this clutch will not engage, and damned if I won't find out. - Darrell

 

if you put the car in gear can you push it? could you have over tightened the clutch cable?

Push it for what reason? And yes I have checked the cable, that was my first guess. I had thought the cable was too tight. I now think the difference in the fly and trans is my problem. But now I need to know if an 90-91 clutch [ all models = the same ] will bolt to an 89 [ DX ] flywheel. Thanks for the reply, - Darrell

 

The problem is probably in the axles seating in the dif i EXPERIENCED almost all of this fun **** whin i got my 1st 88 crs dx 3 years ago later swapped d16z6 went 12.63 117 mph on 175/75/13s at rockingham nc which it then became BDASD16Z6X but thats besides the point when i first got the car it had a slipping clutch so i replaced it the car pulled off just fine went down the road then all of a sudden stopped woulfnt pull could shift through the gears without pressing the clutch ( this is because no load is on the tranny without the axels properly seated) pulled the car home at the driveway the diff locked up burning the hell out the clutch the last 30 feet had to change clutch disc the diff had locked to the axle it hadnt been destroyed yet seated the axle **** worked still had to replace diff and tranny housing **** kept leaking but it worked yours was destroyed by your motor tho dont know the extent of your damage the flywheel is not ur problem unless you have no pilot bearing right now I have an 88 flywheel 88 act heavy duty pressure plate 89 organic disc 4puc unsprung and sintered kevlar that comes right to the fu@k$%G edge but it works why I love this block I cant get that stupid 88 flywheel off had to haul *** 89 tranny (replacement) had to haul *** 11's in april

Billy Madisons' Principal = At no point in your rambling, did you even come close to an intelligent thought. I award you no points, may God have mercy on your soul.

But really, wtf are you talking about? The only good idea I got from that was making sure the axels were seating because they are what puts a load on the trans. Hopefully that was all you were trying to convey. It is helpful, thank you. BTW - I was just pokin fun, no harm intended - Darrell

 

Morning Bump.

 

thats funny . good luck with the problem. wish i could help

 

I had the same problem with my passenger side axel popping out of the trans.. If thats not your problem it could be in the clutch/flywheel. I'm not saying thats your definite problem, but there is a difference in the clutchs/flywheels. since your using a DX clutch I would try to get a DX flywheel. I'd match all your components, to the same year if you could.

what were you in an all wheel drive skyline with 4 gears?
that math doesnt add up

 

**UPDATE**

Well, I broke down and bought an 89 Flywheel and 89 Clutch. Well, from now on, I will buy the fly/clutch to match the trans. Because none of the combos I tried worked. To all those swapping in diff year parts and mixing and matching, if you are not DEFINITELY sure your combo will work, just do it right the first time and buy the right stuff. Take it from someone who pulled a motor 4 times in one week while working 8 hours and school for 4.

Now my problem is my driverside axle is popping out, I've checked the ring clip on the end and made sure its large enough to grab onto the diff groove and small enough to stay on the axle. But it pops out after driving a while, infact the axel seems short. I've used the same axels for the last 2 trans, but they were 88 Si trans. Anyone have any insight into this problem? Search is yeilding unsatisfactory result. Thanks all for your help and replies, - Darrell

 

So that fixed the past problem though?
