Long story short... I have two '84 duke Fieros here. The one I'm trying to fix (car A) I bought years ago for a "good" price because the previous owner couldn't get the clutch to disengage after he had installed the clutch and tranny. The other '84 (car B) has a cracked block, but at least I can use it as a "guide" while trying to trouble-shoot the one I hope to get running. When the clutch pedal on car A is pressed nothing seems to happen. It's as if the clutch lever won't move. It's not a "mushy" pedal. The previous owner thought something was installed incorrectly inside the bell housing. Anyway, I've got some pictures here comparing the relative position of the clutch levers on both of these cars. I'm hoping it's easy to see that the clutch lever sits differently on car A than it does on car B. The red line shows the angle of the clutch lever mounting bolt with the clutch fork pressed against whatever it presses against. The green line simply identifies two bolt heads in each picture that can be used to locate the relative position of the clutch lever in the matching pictures. The right hand pictures are simply tighter shots. It's the pictures above and below each other that need to be compared. If this makes sense to anyone, could I please get some feedback on whether or not car A has the top of the clutch lever postioned too far over towards the passenger side of the car. What would cause this? Could the clutch fork not be properly engaged with the throwout bearing or what?

With the slave off, you can always flop the release lever back and forth a bit. Are both the A&B shots with the lever pushed towards the passenger side? If so... ummm... that's just not right.
With the slave rod off, your clutch pedal should be rock hard when pushed with hand pressure. No movement at all. Any movement means you have air in the system. DON'T push too hard! You'll blow the piston out of the slave. |

Yes, all shots were with the clutch (release) lever pushed towards the passenger side of the car. There's about a half inch or so of play back and forth with both levers. So it does look weird, doesn't it? Right now I have the banjo disconnected form the clutch pedal as the pedal assembly is pretty bent up. I suspect the previous owner was pressing pretty hard to try and disengage the clutch before he realized it was probably an internal issue.

Yeah, something's foobared it LOOKS like.
It's possible that someone put the release fork in the wrong spot on the bearing (like, not in the groove but behind it, etc etc). So... just take a hammer, knock an inspection hole in the bellhousing... ![]() |

I feel like creating a few "inspection holes" in this car about now.

It's ok - it's an '84. Nobody will mind.

Ah, but this one is different. Except for having a rear deck rack instead of a wing, it has all the body panels from a notchback GT, which includes the aero trim and an aero nose/rear bumper with dual exhaust cutouts. It's much prettier than a regular '84.

No one hates the 84's due to there looks, they look the same as an 85 coupe or 85SM6. Its the changes in wiring and engine tech that makes them less desirable.

Yeah, like the average noob who buys a Fiero for the first time knows anything about that. Most people just want a car that looks nice and runs nice. If they know where to stick the gas at the self-serve station they're doing well. Not a helluva lot of people are going to be concerned whether they have flat tappets or roller-lifters in their duke.

Just an update for this thread. I've reported Here what the problem turned out to be. Yep, something was messed up with the clutch fork all right.
