help please! clutch slipping badly after new clutch install
 

i have an s14 that was swapped to manual and they used an s13 tranny so i needed to pull it out to drill the crank sensor hole and since the tranny was getting pulled out, then might as well change the clutch too. so i got a duralast clutch kit from autozone and replace everything and now my clutch slips super badly. and my pedal feels kind of tight like the clutch is too tight in there and doesnt let it engage all the way. i dont know what it could be. any advice would be great! thanks guys

Adjust pedal play ...

re-surface flywheel?

Adjust the clutch pedal. There's a rod above it that is connected to the master cylinder.

Like said, adjust the pedal and break the clutch in a few hundred miles before you start wanging on it.

ya i got the flywheel resurfaced

i will adjust the pedal and probably flush out the system too and re bleed it.

i havent adjusted the pedal yet, i'll give that a try tomorrow.
the pedal feels super stiff when i let go of it though like it doesnt want to come up.
but i will adjust the pedal and probably flush out the system too and re bleed it.
thanks guys

ok, well i bled my system again and i adjusted the rod/pedal a few times and tried it out repeatedly but my clutch still slips badly. the pedal adjustment seems to only move my pedal up higher or down lower, it didnt make any difference on when my clutch engages.
i dont know what else is wrong guys :(

Crawl under the car, pop the dust boot off the clutch fork and see the carrier moves some in there when you move the fork by hand. If it doesnt move, you got the wrong carrier/TOB and its preloading the clutch.

thanks, i will give that a try next. so if the bearing doesnt move at all? then that could be why my clutch feels like its not engaging all the way? how much play is it suppose to have?
i'll keep you guys updated, thanks for all the helpful responses.

If you dont see the carrier move, then it could be too tall and the transmission is pushing it against the clutch.

When you changed the clutch, did the tranny slid all the way in or did you have to pull it in all the way by bolting it in?

i had to force the tranny back in by bolting the screws in the bell housing. but i thought it was because the pilot bushing because it was really really hard to get the alignment tool all the way in, and when i did, it was really hard to pull back out. but ya, i bolted it in to get the tranny to slide all the way in completely flush.

Were you certain that you had the input shaft splined with the clutch disk? How much of a gap was there when you decided to "pull" them together?

ok well i went under my car and i tried moving the clutch fork and there was absolutely no play in it. it just stiff.

there was prolly like half of an inch gap, the splines went in correctly, the bell housing just didnt sit completely flush so i started screwing it in. but i think it was because of the pilot bushing because the clutch tool was hard to get in because when i put the pilot bushing in, i tapped it in with a socket that was the same size and i think that flattened the lip a bit, but i eventually got the tool in and aligned everything and torqued it down right.

i dont know what it could be :(
so the clutch fork is suppose to have some play back and forth?

Marginal, if the Hydro system is strong and in place.



Does the car actually drive, or does it continusously slip? Or does it not go into gear (grind). It almost sounds like you're describing a grind more than a slip.


I'd have a friend watch slave cylinder movement myself (or setup your camera to record it to see it move while you push the pedeal). If it's not moving, then rebleed the system (you did remove the damper block correct?). If it is moving, and shifts gears fine, yet slips under power, I'd suspect a crappy clutch,or a uncleane pressure plate/flywheel.

Hey man I need a day where we can just rip her apart and go thru her 1 step at a time cuz my clutch works perfectly after the first install ,, hope u kept all of the parts ,, btw this is Eric add me fool

Ya the car drives, it goes into gear and doesn't grind. I can barely drive it though because it just keeps slipping, like there is no way I can drive this thing on the freeway because the more gas I give it, the more it just revs up. I can only drive it if I barely feather the gas pedal. And also,I only have to push the clutch in about an inch and im able to change gears

For sure man. Which clutch kit did u buy?

I got the Exedy OEM replacement Exedy 06054 OEM Clutch Kit 91-98 Nissan 240sx KA24DE .. It works like a charm

nice, it's pretty cheap too.
but i still dont think my clutch kit should be that shitty that i can't even drive my car =/
something has to be wrong. im gona order a new kit cause i can swap them out for free cause i already had a warranty on it from 5 years ago and just do the job again i guess.
fml :(

You did clean off the pressure plate before install and make sure the flywheel was clean/good too right? Technically you're supposed to resurface them, but I can tell you from first hand experience that that doesn't always happen, and cars drive just fine for years on the same flywheel surface (again, so long as it looks good)

If you got a really cheap kit, it could just be a weak pressure plate too. It does happen. Heck even with good kits you get a bad egg once in a while.

ya i got a cheap autozone duralast clutch kit but that's because it was free and i dont have any mods on my s14. just daily driving it.
i got the flywheel resurfaced before install too.
i guess im just going to do the job again and see what happens.

If there is no play in the carrier/TOB, I think you got the wrong setup in there. Just out of curiousity, what clutch was in there and what clutch are you running now?

ya, everything is installed and i climb under my car and try to wiggle the fork and its just super stiff. so that makes me believe that the clutch is being partly engaged or something, that's why it's slipping.
i dont know what clutch was in there cause i bought it that way.
but now im just using a duralast clutch kit from autozone.

So is the problem still there?

just get the exedy kit and call it a day.. lmk so I can make it out there to help you
