| Can someone identify if this clutch pivot position indicates that the clutch is stuck (Page 1/2) |

Title pretty well says it, I took this pic earlier today. I just installed Dickman's rear line repair kit so I've no idea if this is the engaged or disengaged position for the fork or not. If someone could chime in, it'd be much appreciated. This is an 88 gt 5spd. Thankyou.

Yeah thats stuck out for sure. Loosen the slave and the lever should come back. See if the pushrod got sideways in the slave bore and check for leaks.

Is the piston corroded/stuck in the slave bore?

Negative to both, there is no pressure on the end of the brand new slave piston. It's almost as if the pivot arm is stuck engaged

I just replaced it, the odd thing is it appears stuck disengaged but stuck. The pivot arm I'm able to get maybe a 1/4" movement in either direction and that's it

So... it wasn't just the "rear line repair kit" that you installed?
Diagnosing from a distance is made all the more challenging when we're not being made aware of all the details. What all was replaced? Does the slave piston move smoothly all the way from the bottom of the bore to the top and back again (and/or vice versa)? And what was the position of the clutch arm prior to replacement of whatever slave components?[This message has been edited by Patrick (edited 12-31-2024).]

I installed the new slave after the rear line replacement yesterday after I posted the initial question. The piston wasn't even contacting the pivot arm, there's no pressure against the piston to have any stroke in the slave because there's nothing pushing it in. That goes for the first slave also, but given it's age a replacement should have been done. The clutch pedal is stiff because there's no pressure pushing back against it from the pivot point. That pivot has to come towards that slave piston. The only idea I have is that somehow it's either gone, or laminated to the flywheel at this point. Not sure how that could happen if the car was just sitting, which it obviously had been at the time of purchase.
The clutch arm pivot is in the same exact place as it was when I purchased it.
I was hoping someone would notice the distance off the arm was either clutch in or clutch out. It appears to be stuck engaged. Looks like now I get to find out if that's an engine out service or if there's access through the drivers wheel well.
Thanks for the reply.

Look/stick a camera down to see the pivot for the clutch release arm, I don't know how common it is on what appears to be the later/cast arm, but on mine (85 stamped steel arm) cracked and rotated freely on the pivot, clutch fully engaged, but the arm rotated to the disengaged position

The pressure plate should be pushing that arm back to the engaged position. Maybe someone did a clutch job and didnt line up the disc or pressure plate right and its all jammed together. Or the lever has slipped or was moved or broken.

I have a getrag sitting here for a swap and I took some pics for you
I found if I move the lever too far back, the TO bearing gets crooked in the shift arm lever thingie and doesnt want to retract
Dunno if that helps but now you know what the innards look like
