Hi. Lately I've noticed a very audible "squeal" (don't know how else to put it) when letting out the clutch in 1st gear. Pickup is smooth and it only does it when starting from a dead stop. There's no slippage. It doesn't do it every time (about 60% of the time to make a guess).

Clutch is an old (original) Textralia OZ700 with the original flywheel (they didnt have the aftermarket one available when I installed the clutch in 2005) + a McCloud adjustable master cylinder. Clutch has about 30000 miles on it, mostly street driving + about 75 drag passes (no powershifts). It began to squeal on engagement about 5K miles ago.

Thinking it's just an aging thing with a high-pro clutch on an iron flywheel...... but....... Any $0.02 appreciated.

With that type of clutch, I would expect it.

yeah, sounds normal. My monster stg 3 does it. But after a couple track passes it goes away for awhile

I can't speak for Textralia, but, this sounds just like the clutch is either being glazed, or, because the mileage it's hitting the rivets from the disc. More than likely it's a glazed disc that needs to be "cleaned" by beating on the unit a bit and adjusting your driving habits to not slip the unit as much.

Call the guys at Textralia and go over it with them.

Appreciate the input. I'll give her a couple good "drops" to clean the disc. That makes sense, as I have a lot of stop/gop where I need to slip the clutch when going onto military bases (which is when I notice it the most).

Thanks

ya my monster stage 3 squeals when going from a dead stop in first also. i am driving alot of stop and go and have not beat on it in awhile so thats probably why

My SPEC 3 has almost always done that, it started after about 100 miles it would make the noise when the clutch was cold, but after a few normal take off's it seems to go away till the next morning or after work when it was cold again. If yours just started doing this after 30,000 miles and it's doing it all the time then I'd think the clutch is almost done.

I know it's not "almost done". I beat the hell out of it fo 10K miles and the pressure-plate bolts backed off. Basically stuck the car in 3rd gear ad I had to remove the trans/ re-torque the bolts. Even with massive slippage to get the car home from the track, the clutch looked brand new. The Textralia Reps from Australia wee cool as hell and offered customer service the entire process. After that abuse and seeing the clutch surface, I know it's not toast now. I definetly believe that "puss" driving glazed it though. I've been rough on it the past 24 hours and the "squeak" has diminished.

Thanks for the help to all.......

LOL Well it's always a good thing when a little bag'n fixed the problem, maby that's all mine realy needs, my 10 bolt diff...not so much LOL

Mine sounds just like the video. I need to beat on it a bit and stop slipping it so much.

SimRacer1

Wow mine sounds IDENTICAL to the video, seems to mostly do it when it's cold and back out of the garage, I also don't drive it hard enough and probably Slip it to much aswell, I also have a Tex oz700, seems we got all these points in common

I've got the exact same clutch and flywheel & have the exact same squeal, letting out in 1st gear as you described!

Unforunetly, Its the nature of this clutch...Like posted, it glazes up some and makes that noise, slip it a few times cleans it off nicely and is quite for a while, but doesnt take long for it to start squealing again.

my new gm clutch make same noise today, just finish break it in too.

The greatest cause of squealing during take-off is in fact glazing. This is especially notable in higher-performance compounds with a metallic component. As mentioned, if the sound is relative to glazing then go out and get on it a bit and see if the sound diminishes. If it is glazing related it will get better.

Temperature can also lead to sound with discs using this type of disc compund. For instance, in the winter you are more likely to hear this noise than you would in the summer. This is normal and doesn't indicate any issue. That being said...get out there and drive that thing and let us know if you have any further questions. Thanks!!
