alright i have a 90 si hatch, stock. i replaced the clutch 20k ago with an exedy clutch kit and for awhile everything was fine. recently ive noticed a grinding noise when my car is in gear or in nuetral with the clutch released. when i push the clutch in the noise stops. the reason i think it might be the pilot bearing is because i found the new pilot bearing a few days after the clutch installation and realized that i just used the old one. some others tell me its the throwout bearing, some say just add more fluid to the tranny. any ideas?

 

no throwout bearing....would make noise when you pushed down the peddle

 

ok, besides i replaced the t/o bearing.

 

Either pilot bearing or mainshaft input bearing are my guess..

me too, hopefully we can both benefit from this thread

 

mine did that, clutch in no noise, clutch out noise...it was my main shaft bearing! new trans sloved my problem

 

so main shaft bearing isnt worth replacing? this is already my second tranny since i got the car last year should i be on the search for another?

 

im not sure exactly how much it costs to fix it, but around 400 im sure atleast, im gettin a imported tranny with 40-50,000 miles for 270...i would look around for another one

 

so would i just bout my si cable tranny for $200 from a guy just north of tampa in tarpon springs... hopefully i can get it in next weekend

i wanna keep the fith gear out of my dx tranny taht i got now because i do alot of driving on teh inner state and everyone cruises at like 80

 

its the main input bearing. mine was easy to replace just have to take the tranny apart.

 

its not a throw out bearing if it makes noise with clutch peddle out...i need to know what gear it makes it in.. if it makes it in neutral.. when your moving in neutral....all of the internal transaxle bearings can be diagnosed with a road test. make a log of when it growls when it doesnt and then i can help you furhter.....But a throwout bearing is engaged when you push the peddle down.... when the peddle is up it just free wheels....send me a pm when you have the results of the road test..... and 400 dollars to replace a bearing... dys and it will be 20 bucks including tranny fluid.... 400 bucks would be what i would charg someone to do it for them....

Yeah, $400 if you were crazy enough to take it to a shop! Do it yourself! I've rebuilt many Honda transmissions, and the ISB is one of the easiest things to replace. Get a Helm, your toolbox, and a beer and have at it!

Don't bother, the gears are the same in the Si and DX trannies, the only difference is the final drive. If you want to have a tall 5th, find an HF, but good luck with that. With the Si final you still aren't going to get the amazing HF milage, but it will be an improvment (~1000 RPM drop at highway speed). This link can show you what to expect with tranny hybrids.

 

so what is it guys? my clutch pedal makes a really loud squeaking noise when im releasing the clutch slowy like i would be going into first gear happens & just releasing it period. even when im in neutral also( anyone know the answer to this problem? hopefully i dont have to spend a lot on it..& hopefully it needs some WD-40 or something!

 

i know this is covered all over the place but does anyone have suggestions on what fluid i should run and how much in my tranny after i replace this bearing?

 

bump

does anyone know what bearing/part number for an mainshaft input bearing for my 90 si tranny? i cant find it on majestic honda.

 

ive seen over 5 cars with that stupid noise. keep driving it, nothing bad will happen.

its not worth your time imo to replace it.


i rode on that **** bearing for over 70 000 kms with no problems.

 

just to let you know si and dx trannys are very different than just final drive
the zc tranny and the si share all the same gearing exept as follows
us civic si 1.894 1st 3.250 2nd 1.259 3rd 1.107 4th 0.771 5th 4.25 final
jdm zc 19.44 1st 3.250 2nd 1.346 3rd 1.107 4th 0.878 5th 3.88 final

 

almost forgot check bad balancer shaft and ive got a tranny for 150.00
or the whole car for parts stripped though,.

what happened when it died? tow ride home? mine is making this same stupid noise, shop said $300 to take apart the transmission and however much the bearings cost...my car is stock...so i think i will just leave it in and learn how to swap a transmission then.

 

did u ever find the problem man mine doing the same thing and its driving me crazy
