EA Falcon bearing noise?

I was wondering if anyone could help me with a noise from my EA Falcon around the gearbox. When in neutral with the clutch pedal down everything is fine, but when I lift my foot off the pedal (still in neutral) it makes a reasonably loud 'wirring' noise, like a bearing or something. It's hard to describe but it's been there for a while and it's getting a little louder.

I suspect it may be the input shaft bearing, but I sincerely hope not because I am an extremely poor student!

Any ideas? Do you think it's ok if I let the noise continue? I really odnt have any money to spend fixing it at the moment, but obviously will find some if it's an urgent problem, although it's been going for a good 3 months and I havent tended to it yet.

Probably the clutch carrier, about $20. Trouble is, Ford engineers, in their often-sneered at wisdom, failed to have the intelligence to put an inspection plate in the bellhousing, meaning you're going to have to pull the box to fix it.

Clutch carrier? Is that the throwout bearing?
Sorry I've never heard of a clutch carrier

I did think it might be the throwout bearing, but I only put new one in about 4 months ago, however I did notice when I was doing my clutch that there was a strange weld on the clutch fork, as though it had broken and been welded back up, maybe this is what put the throwout bearing out?

Cheers mongrelEB.

I'm also unsure what a clutch carrier is, but I think you may be right about the input shaft bearing as this is the only bearing turning when the foot is off the clutch.

Re: EA Falcon bearing noise?

Clutch carrier = bearing on the clutch fork. Noise with the foot off is usually either that or the spigot bearing in the back of the cranksfat.

Re: EA Falcon bearing noise?

um...if the clutch pedal is out it means that the input shaft and crankshaft are rotating at the same speed, therefore the spigot bush/bearing would not be moving at all, and therefore unable to make a noise.

i think its the input shaft bearing, but dont dispair - my car has been making this noise since i bought it, and 40+ passes down the drag strip plus general flogging the crap out of it and the box is still good :s6:

if the noise changes suddenly then i would be worried, but if its just a grumbling like e bearing noise i think you might be right to just ignore it, unless it really upsets you.

Re: EA Falcon bearing noise?

yeh true spigot bearing would be doing the same revs. Leaves the carrier then I guess - Rollin, having rebuilt a couple of these things I can guarantee you your problem is not the input shaft bearing. Input shaft has it's own cone-type bearing and then between the input shaft and mainshaft are a bunch of needle rollers. The mainshaft flogs out over time due to poor oiling and must be machined and resleeved. If the input shaft bearing was knackered, it'd put a lot of pressure on the needle bearings and I doubt it'd have survived that long with 133 rwkw plus regular drag runs
