Symptoms of a bad clutch slave?

[Barney Paull-Edwards]

Try the coke method, it clears crap off the plate a treat but does not contaminate it.

we just did a tranny in kyles tcd turbo'd 535 and the rear main was puking all over the puck clutch, degreased it and scuffed the carbon off the buttons with a rolllock, t'was good ta go and hooking up like it's supposed to

I will order a new slave, and i think i will just slip the **** out of the clutch to burn the **** off.



"The solid hub metallic button discs are capable of withstanding the highest possible loads that can be transmitted through a disc of its size."

So its a metallic ceramic puck. I bet I can just roast the crap off once i get it to stop leaking.

Thats the beauty of ceramic puck clutches.

In fact, tonight on the way home I was just pissed so I floored it in 4th and built boost and watched the tach slip upward. After about 1 second of slipping, then a baby momentary slip again, the clutch cleared up and pulled hard.

Jon, I was out all day today just reading the thread.

So it was the brake fluid spraying onto the clutch as I thought. You are a lucky guy, I have hardly ever seen them do that

Guess it was spraying onto the clutch, knew it was possible but very rarely happens.

Have fun pulling the tranny

That shouldn't be necessary. The ceramic pucks don't absorb the fluid like an organic. I was able to do a 4th gear pull with slip at 5,000 rpm, but after maybe 1 full second of slip, the fluid must have momentarily burned off and i was pulling to redline full-force. Once I get a new slave cylinder, I'll be able to burn the fluid off the clutch combined with spraying brake clean up in the housing. If it doesn't resolve itself, which I am very convinced it will, I will just wait until I have the motor out in a month or so and drop another $120 6 puck (maybe 4 puck) disc in.

Oh you have a ceramic 6 puck clutch, I was just read your reply about seeing the cylinder spewing fluid onto the clutch. Wow nice that you were able to burn it off and get the car pulling all strong again

Seeing that you are using this clutch, what's your impression? I have to make a decision sometime soon as to which direction to go regarding this. I have the much sought after lighter flywheel from an e28 for my e34 m30 b35 engine and do not want to wear the flywheel prematurely.

I will be turbocharging the e30 once I get the m30 broken in and running well NA before going FI. I will be concerned about both clutch bite and at the same time longevity of the flywheel. I know one compromises the other, but need your input.

Thanks.

Flywheel should be ok. The clutch is great in terms of price and function. Its a little jolty (when brake fluid isn't all over it) due to my choice of unsprung and 6 puck. But, it grabs positively - supposed to be good for over 650 ft lb of torque with the "3x" pressure plate - its a bit on/off but I am used to that in all the cars I drive.

I wouldn't worry about the flywheel honestly.

Thanks for the input Jon, I will definitely look at this clutch. I can understand the on/off feel, how but does it affect launching from standing still? More prone to stalling? Guess you have to keep the revs up a lil bit higher from that of an OEM clutch to launch.

Whose clutch kit is that BTW?

Thanks

You know better than to do that don't you? Just wash it down with solvent/brakleen if it's oily.
