clutch problems

"bent clutch pedal" is that a frase or could the foot pedal litteraly be bent.
 >> Stay informed about: clutch problems 

Literally bent.

Is your clutch pedal pad above, the same as, or below the level of your
brake pedal pad?

it is the same.

Contact the fiero store. Get a new clutch pedal. That's your starting
point anyhow.

Taking the pedal out is fairly straightforward. There is a
long bolt that goes through both the brake and clutch pedal
pivot, you pull the bolt out far enough to allow removing
the clutch pedal. When you look at the pedal you will see
that there is the main arm of the pedal and a smaller
secondary arm that's riveted to the main arm. The small
arm and main arm should be parallel when viewe from the
side. Commonly the small arm will slowly bend toward the
driver, reducing the travel at the clutch master cylinder.

Why does the arm bend? No one really knows, but likely it's
fatigue from cyclic loading.

As an engineer, I'll venture that it is not fatigue, but simple overload.

Fatigue normally requires load reversal and results in a crack, often too small to see until the
break happens. You'll see what are called beach marks at the break - they look almost exactly like
the way sand does when the tide goes out, each wave unable to reach as far as the previous ones. And
the crack will be relatively smooth. I've seen breaks that look like they were done with the
thinnest jeweler's saw.

Overload just deforms the part, possibly a little each time, depending on how close the load is to
what was required. Pound a nail halfway in. Then give the side a tap. If you tap it just hard enough
it will bend a little. A few hundred taps later and the nail will be bent pretty far. One thing that
will slow the bending can be 'work hardening.' You'll have to consult a metalurgist on the specifics
of work hardening, particularly if the part is non-ferrous.

Perhaps GM forgot to multiply by the clutch pedal factor of safety or used a 1.

Even so, I'm going to look at just that feature on my clutch pedal, Jazzman. Seriously, I wouldn't
know what it was supposed to look like otherwise.

Your experience in the field trumps my theoretical bent. Although, if the theoretical part had been
done correctly, the clutch pedal wouldn't fail.

Yeah, I'm nit-picking, but 25 years in aerospace -could- count for something.

i had my the clutch looked at by a friend who is a retired mechanic and he said that the pedal was not bent yet so now i am confused i also bled the clutch still nothiing. i did take the transmision out once but had to put it right back in without looking at the clutch i was thinking that mabey somthing happend that i didn't realize or mabey this guy dosen't know what he is talking about how would i know if the pedal is bent.

any one want a fiero

i can shift gears when it is not running.there is play in the push rod.about three inches
when i recieved the fiero the pedal was the same i got it broken so i don't know if the pedal was any diferant but it feels way to easy when i push it it. but it feels like the clutch pedal is doing nothing untill the last 1 inch or so of when i push it down, like the clutch is jamed with only about 1 inch of room to move... is this making sense?

How about the push rod when the pedal is pushed how far does the push
rod move ?<!-- ~MESSAGE_AFTER~ -->

about three inches

When I say the push rod I am talking about the pushrod that is moving
the shaft arm on the transaxle it should move about 1and a half
inches.
The shaft arm pushes the throwout bearing into the clutch plate when
released it should spring back into place.
If this appears to be working correctly then most likely there is a
problem with the clutch or clutch plate. You wont know until you open
it or it could be a bent fork against the throwout bearing.<!-- ~MESSAGE_AFTER~ -->
 >> Stay informed about: clutch problems 

What the problem turned out to be for me is that the bushing on the
tranny case for the throw-out fork was SO BOUND UP, that it was making
the hydraulics push to the max... I removed the tranny, took out the
bushing (which took a LONG TIME) and cleaned everything up, filed it out
a little, lubed it up, and the problem was completely gone... I have had
no more problems with it since... Clutch works just like a new car...

If you need more information, or pictures let me know..
