I recently bought a MY2000 with 45K. As far as I am aware everything is stock. It had the buzzing/ rattling at deceleration that was diagnosed as a bad clutch disc which I had replaced at a Honda dealership. At the same time I had the pressure plate and bearings replaced. This corrected that problem. Unfortunately, after the work was done I am getting new noises. When the clutch is catching I hear a faint to moderate buzzing sound. This does not happen when the car is cold or after I have done highway driving but only seems to occur when I have used the clutch often. It also does not happen if I let out the clutch without giving the car gas. I can slightly prolong the sound if I ride the clutch a bit. Honda can't seem to diagnose the problem and says it is the way I'm using the clutch. That doesn't make sense to me since it only happens when the clutch heats up, and it didn't happen before the original work to correct the deceleration buzz. Can anyone help figure this out?

 

I am not familiar with a "buzz" when engaging the clutch, but it is quite common for people to report a rattly sound when the clutch is disengaged. Some (myself included) can even feel the rattle in the clutch pedal. I think the concensus is that it is just a noisy throwout bearing. Mine hasn't gotten any better or worse in the last 32K miles.

 

I started to notice this "rattly" sound when my clutch is disengaged and my vehicle is an 03 with 700 miles.

I also have a Honda Civic that I replaced the clutch with 192k miles for the first time about 2 years ago because the disc was worn out. I replaced the disc, pressure plate, and release bearing. After installation I started to notice a slight "racing" / buzzing noise when the clutch pedal was disengaged and partially engaged. It got louder over time. I diagnosed it with the help of the Helm manual as a faulty transmission main input shaft bearing. I took it to a Honda dealer and they confirmed my thought. At 256k the transmission was replaced with a used one because the bearing noise was very loud. I asked my mechanic if he thought I installed the transmission incorrectly or if I crushed the pilot bearing when I put the transmission back in place, but he said everything looked fine ? I don't know if this helps you emm12, but maybe someone reading this with more insight could let us know if it is possible to damage transmission bearings or other parts with a faulty installation or misaligned clutch ?

Good Luck.

 

This is the second recent reference to a misaligned clutch. What would that mean? I have installed a number of clutches and there is no alignment to it I have seen. You do have to align the FD in order to insert the main shaft but that is just an installation step. What are people talking about with this alignment stuff?

 

The misalignment reference comes from the installation step where you would use the alignment tool to center up the disc on the pressure plate and then torque down the pressure plate. I was thinking that if it were not centered correctly before the pressure plate was secured it may cause problems when the input shaft was forced through ? Is that possible ?

I agree that if the alignment tool fits correctly, you can't misalign the clutch.

*HOWEVER*, it would be possible to start the transmission input shaft through the disk and into the pilot bearing, then mess up and let the transmission hang from the shaft. This would bend the input shaft, which should wreck havoc with its bearings sometime later.

I just wrestled a '94 Integra transmission back into place with just a floor jack (operated by my wife while I was under the car) and can definitely understand how this could happen.

More likely damage to a bearing.

 

When you bolt the flywheel to the pressure plate, is it possible the pins that center the pressure plate are out?
