Hey guys, did a mantic 9000 twin disc clutch this spring on my own. Been driving the car like this as i havent had time to wrench on it.

Heres a video of the noise.


The noise goes away by either pressing down on clutch pedal or just pushing the shifter forward/pulling backward(without depressing the clutch or engaging gear) just some forward or backward pressure.

So im wondering what it could be. And also, i still havent gotten around to installing the Tick Master.

Thanks everyone

That's normal that how mine sounds. Just broke it in. 600 miles. So far good

Georgies

Normal??

Honestly, it sounds broken lol. Its louder than my exhaust. Its very annoying and makes my vette sound like a **** box..

sounds like a twin disc... does it go away as rpms rise?... mine sounds similar but not quite as loud as yours, after about 1500rpm it's smooth

Georgies

Yes it does go away as rpm's rise. My car isnt running smooth tho. Rpms are set at 700. Heres another vid showing how the rattle goes away when i put pressure on the shifter.

Georgies

Anyone??

We told you that's just how twin disks sound normally. If you don't like it, I have some special clutch oil that I can sell you, but it will cost you 99.99$ per oz. It will last approximately 30,000 miles and your clutch will be as quiet as a library.

Right....


Why would putting pressure on the shifter stop the rattle??

freddyvette

Because you're forcing your synchros to produce friction (read BURNING THEM UP) trying to stop the turning force of the engine to get into gear. The torque tube shaft is what's actually making all the noise.

700rpm idle sound way too low on that cam and cant get smooth idle. I would rise it atleast to 900rpm, that would also make car shake less and clutch not rattle so much.

Georgies

My exact thoughts...no good dyno shops around here...
