OS Giken twin-plate post-installation questions

[johnnyballs180]

hello all,

this will be my first time ever posting on nico. i've read a lot of threads, but never got around to registering so i could start a thread of my own.

SO, as the topic suggests, i have a couple questions some of you guys might be able to shed some light on.

just to catch up (so this makes sense), i installed an OS Giken twin-plate clutch on my 93 180sx, sr20det. the clutch kit came with flywheel, discs, and pressure plate.towards the end of the install, i noticed a chunk of rubber barely hanging on to the engine mount. and of course as soon as i touched it, the damn thing practically turned to dust and fell out.other than a pain in the *** (not enough tools and bench pressing the transmission for hours), it was a pretty straight-foward install. i have about 40km on the new clutch, and since the instal i noticed the entire car shook violently when going from stop to 1st. after some research, thanks to

the motor mounts (or lack thereof) makes perfect sense. that's all well and good, but after the 30km mark, i noticed a horrible sound. i can't tell if it's from the f'ed up mount, or if it's the clutch itself.

okay, a long intro, i know, but now for the fun questions:

if it were the motor mounts gone bad, should i be able to feel the "knocking" in the actual clutch pedal? of course if the car shakes as bad as it does because of the mounts i'll feel it just about everywhere, but it's the clutch pedal almost feels like there's a hardline going directly to the bellhousing. everything else just feels like "fall-out" vibrations. the clutch pedal almost feels like there's something near the imput shaft, banging around as the pressure plate spins. as soon as the rpms get a little past 1100, it stops.

::EDIT::in addition to the above paragraph, when i BARELY depress the clutch pedal while idling, the sound dampens, almost subsiding. the engine knocking, of course, does not.

question TWO!: when shifting while rpms are at about 3000, i hear this sound which almost resembles the head of a philips screw being horrorifically stripped by a dril.any ideas?

i know twin plate clutches are going to be a lot louder, but is that normal? i was imagining maybe the clutch discs were just pinning on the plate/flywheel while inbetween gears.

this thing is pretty long, i know; sorry for making you read all of that. i wanted to make sure anyone who might have a clue gets all the info i can give.

i really appreciate any thoughts.

I've got the Blitz clutch which is made by ogura....it is very loud at times.....sounds like jingling 2 medal plate together....clutch functions just find though. The engagement is a bit harsh and jerks some as well.

i bought some new nismo motor mounts and a transmission mount. i just finished taking the right motor mount off, and i must say, it's times like these i wish i had a moped.chunks off of the old motor mount were missing, and with almost no turning effort, the top and bottom of the mount, between the two studs, fell to pieces.safe to say it was F***ED to begin with.it's strange, but i'm actually a little relieved to see it in such bad shape; maybe this whole clutch chatter, engine wanting to rip out of the car noise will cease. knowing my luck though, i'm sure after all of this, my windshield will somehow implode while backing out of my driveway.

i'm also praying that the sound i hear between shifting gears is simply the release of pressure on the two discs. it kind of sounds cool.... i guess.... but high schoolers like to poke holes in their mufflers to sound cool too.. and that's not good AND lame.

i'll keep this updated.

I once heard a guy refer to the noise as "baller noise"......if you can afford a multiplate clutch then your a "baller".....lol

If people around you make fun of you for the noise.....they just don't know a good sound from a bad sound.

a million things could have made it easier, but that's just not how i roll.loli ended up taking out my t28 turbo to get to the LH mount. it made perfect sense, because it clearly exposed every bolt i had to reach. taking out the turbo, manifold, and all lines plus all the intake crap took about two hours.i went this route because i had a nice new stainless exhaust manifold sitting on my shelf that i had been putting off installing, and this was a great opportunity. killing two birds with about fifty stones, i guess.all that's left to do is raise the steering rack, do an oil change, add coolant, reinstal the starter, and then put the turbo crap back on.this surely didn't have to be so much of a pain in the ***, but it's rare i have all these things out at the same time; good excuse to bust out the scrub brush and waste a carton of smokes. once i'm finished and tested, i'll post results.hopefully this will eliminate the clutch chatter.

i noted that both engine mounts were completely rotted through; each one had came in half.

update:

i want to cut out the area that would be the center console area in the car.. the area that surrounds the transmission, clutch side, while it's installed onto the car. life would be about 4 hours easier if i could; a friend said it's actually ILLEGAL here in japan (i didn't ask about elsewhere), because if the clutch should explode, that double-re-enforced one-piece metal doo-dad is the only thing keeping it from shredding me to pieces.

in all reality.. i'd much rather take my chances. i would have new pieces welded in its' place.

i want to do all of this because taking out the transmission is way too fu**ing lame and i doubt this'll be the last time i'll pull it off. i might be more inclined to keep up maintainence if everything were easier to get to.

enough ranting.

the flywheel is loose.

DURRR...

when tightening down all the bolts that hold it up to the engine, apparently the bolts BOTTOMED OUT. by the time there was no more thread for it to screw in to, the flywheel had a little bit of wiggle. at 1 in the morning, using a 150W lamp, tired, pissed off, laying down in a puddle of gear oil with the engine not 6 inches above my head, i'm positive the flywheel seemed perfect.

what did we learn here?

the only substitute for a lift and a transmission jack is LOTS of friends. i did the transmission drop today, alone, and it was lame. kind of fun.. i guess.. but i would have really liked to have had a friend who i could say,"i need (insert tool type here)"

i'm thinking some really nice stainless washers that fit perfectly around the bolts will work well. it's only off a hair on all the bolts, but that's enough to cause the sound of DEATH in the transmission. at least stainless ones won't warp too bad on me.

retard explaination:

i THINK the horrible sound i was hearing ceased when i depressed the clutch because there was pressure on the pressure plate once again, which of course is directly connected to the flywheel; the flywheel was forced back into it's ideal position, where it was supposed to be in the first place.

transmission and motor mounts needed replacing anyway, and it's night-and-day.

thanks all for reading. i'll be posting a lot more run-on explainations and wannabe-mechanic-type stuff in the future.

At least you found the problem and it didn't cost you a ton of cash......good job!
