Clutch chirp - constant

So I had a bad clutch pedal assembly and a leaky clutch master - today was the day that I finished replacing it all - new clutch-line-slave, reinforcement plate (also a new radio antenna, cluster LEDs, repainted the needles, resealed the under-cowl area with all the brittle seam sealer).

Anyhow, the truck is shifting better than I have ever had it - the pedal assembly has been bad since I bought the truck and I was none-the-wiser. (Background on that)

Problem now is that there is a constant chirp, speed relative to RPM, unless I have the clutch depressed the slightest amount. Pretty sure I could force this situation by adjusting the master to always be effectively placing some pressure on the clutch (which I know means im wearing out the clutch faster).

The thing I'm wondering is, will this eventually just "wear away"?

The clutch needs replaced, I know this. Not because it doesn't work, but because it rattles at idle when in neutral and pedal not depressed. I can live with that. The chirping will drive me crazy.

You don't have what the transmission is in your signature, but does it happen to be a ZF5? I ask because they have a rattle in neutral with the clutch not depressed.

As for the chirp, it may go away with wear. (In "Are You Being Served" speak, it'll ride up with wear.

) I'd give it a while before worrying about it.

Anyway, if you did all of that in one day you really had a good day.

Haha, It's a t-19.

I really did all this on 3-ish days over the course of a month. When the clutch became an issue, I started disassembly and have been working only when it was okay-ish outside. It was a March project, really.

If you put info like that in a signature we wouldn't have to ask, and our answers would be more accurate.

Anyway, I'm glad to see you didn't do it in one day. I was feeling really old and slow.

I'm free!

No, you couldn't make that show today. And probably shouldn't.

But I'm not sure I want to identify with Captain Peacock. Maybe Mr. Grainger? Or Jug Ears? (Mr Cuthbert Rumbold.) Perhaps Mr. Lucas?

Hard to believe that the last episode of the regular series was filmed in '85 and we moved there in '87. No wonder that it seemed so real to us, especially since my office was literally across the mews from Selfridge's, and I saw a lot of AYBS in there.

That chirping noise would concern me. It can't be a belt so it must be something doing more damage than just making noise (or about to). If it were me, and I had just repaired all of the clutch hydraulics, I'd go ahead and put in a new friction disc, pilot bearing, and resurface the flywheel. While I'm in there I'd check the input shaft and realign the clutch. None of the parts are that expensive and I'm guessing they need to be replaced anyway.

I think that sound could be coming from a worn or misaligned clutch, or it could be from uneven wear on the flywheel. To be honest, though, I don't know much.

Re: Clutch chirp - constant

throw out bearings have been known to give a squeal. rattle and sometimes a chirp. worth investigating for sure. if it is the throwout bearing then it will not heal and as far as "riding up with wear'. its wearing out not breaking in.
