i just picked up my 90 240 sohc ka 5speed. when i start the car up and have it in neutral with the clutch pedal up the car makes a whining sound like its really low on power steering fluid. but when i depress the clutch pedal the whining goes away.

i have a feeling that my throw out bearing is bad but am not certain.would this be my throwout thats bad?

that was the next thing i was going to turn my attention to since i have a leak from the rear seal, and 1-3 gears are a little sticky

If your tranny is going to whine, take it to another website. We don't like whiners on Zilvia.


:rofl: :rofl: :rofl:

Good luck with the fix. Definitely check the fluid.

it's probably the throwout bearing. check your fluid first though.

good luck.

If the noise goes away when you depress the clutch then it is DEFINITELY not the throw out bearing, that would make noise when you depress the clutch (throwout bearing should not quite make contact with the clutch unless your foot is on the pedal). The pilot bushing would only make noise when you are stopped, in gear, with the clutch pedal depressed (flywheel is moving, input shaft is not). What it probably is is the input bearing in the transmission because with the clutch pedal released in neutral that's the only bearing of the three that should be turning. Definitely check your fluid.

my car is a cry baby it whines so much. i was able to drain the fluid today, but by the time i was done the auto parts store was closed.

what kind of fluid should i be using for my trans? the dripping oil from the tail shaft looks red. i thought i was supposed to use 80w gear oil or that lbn or nbl4 or something?

remember gears clack and clunk
those gears are cracked and junk

bearings whine.
so it could be ur throwout or input shaft bearing
jus make sure u got the correct level of tranny fluid
check OEM specs.

i have the same model 240sx but im lazy to check
i hope this helps. :hsdance:

alright so heres what i did today, i drained the fluid which was total crap, added 2.5 qts of 80w90 fluid and changed the trans mount to a nismo one since mines was dead. and still the whining persists. i have a feeling it is the throw out bearing since it gets louder with the rpms.

on a better note i found 2 vaccume leaks, tightened my valve cover, changed my plugs and oil, reset my comp and now the car runs like a champ, but it still whines like a cry baby.

my next task is to swap out transmissions since my gears are still sticky, swap out the clutch to an act, and change throw out and pilot bushing.should be done in the next week or so

Most likely the TOB.

Mostly likely you're TOB not releasing properly. I have the same problem. I adjusted the clutch release point and it seems to help a bit.

hmm when you adjusted the clutch point did u adjust the clutch so that it engages higher or lower? because mines is releasing nearly at the top, but of course i havent tried to look at how its adjusted yet.

on another note, does anyone know how to install a tach?

i got an autogauge tach and theres 4 wires: red, white, green, black. i have a feeling that red is accessory, white is ignition, green is goes to your dizzy wire and black is ground. someone correct me if im wrong. and also does anyone know where to locate or what the stock tach wire looks like?

i say 99% sure its the throw out bearing... might as well get a new tranny like you said tho cause your gears are screwed and the tob is lame... good choice!

i was able to source one locally for 40 bucks with 85k miles so i couldnt go wrong. my ex gf works at nissan so i can get killer deals, and i got a friend that can hook it up cheap with a stage 1 clutch

If it's already near the top then it's your TOB.

Apparently you people don't read very well.

Internal bearing whine

There is a couple of bearings inside, not only the input shaft bearing

it is almost certainly NOT the throw out bearing. like racepar1 said its most likely your imput shaft bearing or one of the other bearings inside the trans. this is most logical because you mentioned that it gets louder with rpms. your tob is not turning when the clutch is engaged and you are in gear. i have the same exact issue with my trans right now and am planing on tearing in to it within a month. hope this helps.

yes it certainly did help me out a bunch. but i am planning on swapping my trans out for a dohc 80something thousand mile one in good shape, so hopefully that will solve my problem, i will change the clutch along with that too. i will keep you guys updated in a bit
