i just completed it 96' T56 w new 4th gen hyd. and pedals. new PP/clutch and FW
when i started car first time no problems-untill---

i pushed in the clutch pedal close to bottom there was a scrapping sound from bellhousing area-release clutch pedal no noise- only when pedal is close to 3/4 travel or greater...

wow i thought this would be a LOT easier to do.

any help.
thanks
mike

OK so it seems my 2 problems are related..starter issues and clutch noise .

when i depress clutch fully the pedal stops do to something internal to bellhouseing--pedal stops JUST enough to allow the clutch start switch to engauge but not enough to start.. when i depress switch fully with my hand -car starts no problem..
and i can see that the pedal is not on the stop.

when running when u depress clutch to the floor it hits(grinds)on something internal to BH.

so i think there must be a problem at the slave/arm/throwout bearing interface???

if i remove slave I THINK it will spring apart and be a pain at best to put together/bleed..


any EASY way to tell?? ...cause if i have to pull trans-it might not happen.

need motivation--this swap was easy on paper.. Smile

advice please
thanks
Mike

The slave shouldn't "spring apart" unless you actuate the master while it is unloaded.

I agree with you that the problem is probably that the fork is not over the throwout bearing correctly, or that the throwout is somehow not engaged correctly with the pressure plate tangs.

If you pull off the slave spacer off the bellhousing you can take a look along the fork, but I am not sure if you would be able to spot anything.

Is the fork backwards?

the issue is with the fork
the spring steel clip held to fork with rivit.

its bend up badly and looose-it has been in contact with PP...and limits travel

when i got the trans, the guy said he had a hard time seperating trans from motor,
said he had to force it apart from engiine----
he forgot to disengauge the fork and broke the spring steel clip removing trans....

I did not ever remove fork from trans, so i transferred that issue to me...

well -new fork, pivot and bolt on the way..

i will install 4-5" long bolts to slide trans back just enough to remove and install arm/bolt but still keep trans lined up to engine for easier re-install..
sounds good on paper...lol...

You can install the pivot bolt completely before putting the trans in place. Once the trans in up and in slide the fork in place from the hole where the slave bolts on.

I would leave the pivot alone unless it is obviously damaged. I suspect the fork clip took the brunt of it.

i have ordered the fork,pivot block and bolt--so i might just as well use them..
unless
is there something about changing that pivot block ???

Just take off the old bolt-install new block-arm and bolt..

seems easy-so what am i missing???

thanks for the help

You're not missing anything, it's just going to be a pain with the trans partially installed.

Usually you do what Ian said and set it all up outside the car, then slide the fork onto the pivot. Not having done it upside down in the trans tunnel I can't say how much harder it will be. Laughing

That's because the LT1 has the world's stupidest clutch setup. Laughing The throwout bearing clips into the pressure plate tangs so you have to slide the fork onto the throwout bearing after the trans goes in.

The issue is that IIRC you can't entirely remove the fork through the access cover on the bellhousing, just slide it on and off the pivot, so Mike will be disengaging the trans at best, and possibly removing it entirely.

I will call it a success
got the new parts and they are installed...

car starts as normal, no noise from clutch at any time

and my pedal pressure is normal-it was very very heavy before....

now on to see if car actually go's in gears and moves....

1 step at a time..

thanks for the support and help
