I have a SBC single disk organic. Has been working great! Today down by Columbus, OH while bobtailing in rush hour traffic, I missed a shift. The clutch got worse as I got closer to home, 2 hours away. The last 10 minutes of the drive I was without a clutch. I even had to drive around the block a few times waiting on a train.

I think I just need to bleed the hydraulic clutch. Does anyone have a good method for doing this.

Any other ideas also would be helpful.

Thanks HandShakers.

It does

Thank you!

Now to find a Mity Vac and the adapter on a Saturday will be the trick. If I can find the pump I think I can Jerry Rig an adapter.

the only thing that bugs me is I have been driving 20,000 miles since I replaced the clutch and all. Why now?

When it went out it went slowly like a leak. The reservoir is still 3/4 full. I am assuming bleeding will corect it.

well i know if dad's pu get warm pulling a hill with a load on behind when you go to push the clutch pedal down there is nothing to compress , and the pedal just goes to the floor. we have the same clutch set up i believe. i think it is the fluid in the slave cylinder boiling. try it after it cools off overnite and see how it feels. make sure and use the dot 4 fluid. dot 3 is compatible but brings the boiling point down.

I had that

with my stock clutch setup. I have never had a stiff pedal with the SBC. That and I didn't have a load so I don't think that is it but thanks.

BTW, Chevy replaced my fluid with DOT 4 back at 35,900 it was slipping and heating up and they had a tech bulletin to do so. I have ran it since.

Here in 20 minutes my parts store opens I'll get the vacuum pump and see what is up.

let us know how it works out for you. i went in to my local chev dealer and he kept pushing dot 3 and i kept telling him he was wrong and they said that is what they used when servicing . i nicely told them they were incorrect and showed them the owners manual and the lid off the clutch master cylinder res. and they looked at me like i was from mars. never heard of such a thing. have the dealership show you the dot 4 container. the parts people told me it wasn't availible either. bought mine right here online.

You said originally that you missed a shift. Did it do anything else? I wouldn't have bet that it would have come apart...

Nope

I wasn't even loaded or even really hammering on it. Suprised me when I got it apart. I was expecting a bad throwout bearing, concentric or what ever it is called now days.

Dogface,

Sorry to hear of your troubles, but thanks for posting this. What are your next steps? Are you going to stay w/ an SBC unit?

Missing a shift sure as h3ll didn't cause this...

I will work with SBC

and the dealer that I purchased it through.

From all that I have read and heard SBC backs their stuff.

Hopefully I can get it back together tomorrow

Got it back together yesterday

I went to SBC, met Peter and he squared me away.

Replaced the clutch and the pressure plate and gave me a deal I couldn't refuse on a dual disk setup.

I bought and installed the dual disk so now I have a "new" single disk setup for sale any interest?

Good news. Peter give any opinions/insight as to the cause of the failure?

Is the new clutch the sprung hub DD?

You know the drill: you have to post your experiences with the new clutch. :)

Not really, he did say he had one other do the same thing. The only thing I can figure is possibly slipped on ice then grabbed a bite.

Yes it is the new style.

So far it is what I expected. A little "grabby" and my biggest problem that Peter and I spoke of, reverse. I have a 2WD, no 4 LOW to reverse in. Empty is not a problem, loaded with a trailer is like no slip, let it out and go!!!! Better have lots of room and react fast.

I have been considering building a gearbox for my truck for some time. I like the gear vendor but it is hard to justify the $$$$$ That and I don't need to split gears while shifting. I want to make a gearbox that is engaged while you are sitting still in neutral that will have a 3 range selection, 25% increase, 1 to 1, and a 25% decrease. This way when hauling use 1 to 1, when backing a trailer 25% decrease (or depending on how you are looking at it could also be called an increase, basically slower) and 25% increase when bobtailing. I have a decent idea of how to do it in my mind from machinery I have been around. My biggest concern would be how much heat it will generate. I know how to make it sturdy enough, and think I could mount it where the carrier barring is. Just gotta get some time and do it.
