That means I gotta buy those huge fucking allen wrenches, lest the Getrag takes like a 1/4in square? Anybody know which size socket/wrench to get?

My 92 Getrag 260 takes a 17 mm Allen wrench

My 325i chatters in neutral with the clutch out. It was my understanding that the dual mass flywheel was the culprit.

And for those that will say that the 'i' didn't come with a dual mass flywheel, view this thread http://www.r3vlimited.com/board/show...ight=dual+mass

ok heres how to test the tob
in neurtral let the clutch out hear the noise
now if the noise goes away from just lightly pressing the pedal ie not going past the engagement point, its your TOB

if the noise goes away only after you pass the engagement point then its the input shaft bearing/normal gear noise

and im gonna say this again, the noise from the input shaft bearing is normal in transmissions this old and you shouldnt worry about it.

What are you talking about? I think you may have misread this my original post. I mean, my car has always made the input shaft noise, that never bothered me. I'm talking about after I push the clutch in, no matter what gear. The clutch is on the floor now, and the input shaft noise goes away. Then I wait about 1.5/2 seconds and this awful sound starts coming from the clutch area, like I am grinding gears; however, I am not touching the gear lever and the car is at idle. When the gears start to catch, like when I am starting to actually drive and letting the clutch out, the noise goes away, although it varies in pitch according to RPM. In fact, there is a pre-emptive noise as the clutch is in, like a very high pitched squeaky sound that I can barely hear, right before the grindy noise starts.

...You gave me hope that it wasn't my TOB... I wish I could drive my car and not have to worry about the TOB seizing. I had to drive to work today and my car sounded like it had straight-cuts in 3rd... Another problem??

It's definately the dual mass flywheel my eta and both of my i's have done it. mostly when you first turn the car off. i looked it up on all data once and it said something along the lines of "the benefits of the dual mass flywheel are much greater then it's defects (the rattle) so deal with it". it only did it at idle when i had a vacuum leak and my idle was fucked up though

Did you ever get this diagnosed and fixed?
I can tell you only this: driveline noise can travel all over the place...

That means, what you're hearing from the gearbox could actually be coming from the diff. At least, the noise you're describing, and where you're placing it, was my exact problem...and that was diff noise.

I'm not saying yours is diff noise, necessarily. Just that it's difficult to locate noise until you lift that car and grab an auto stethoscope.

OK, so we have eliminated the "Getrag rattle". It's there, but you know to eliminate it as a problem. (BTW, I think it's the aft layshaft bearing, not the input bearing, but that's not important here.)

OK, first eliminiate the possibility of the clutch hydraulics leaking down. Hold the clutch pedal to the floor for a minute. If it returns on its own, the clutch hydraulics are working.

There are two bearings under load when the clutch is disengaged. The throw-out bearing has already been mentioned. The clutch fork always has a rotation relative to a spinning pressure plate on a running engine, so you would hear a bad bearing immediately.

The other is the pilot bearing. My guess is that you are hearing a toasted pilot bearing. You don't hear it initially because the transmission input shaft is spinning at the same speed as the crankshaft. Only as the two change relative speeds does the bearing let out its death scream.

Does this match your symptoms?
What happens when you put the engine RPMs at 5K and disengage the clutch?
