Well I finally got my new clutch in, 465/205 reattached, and the linkage hooked up, YAY:laugh:. Push in the clutch pedal and it stays on the floor,,Ok,,back under truck,,,everything looks fine.
I pull the pedal back and notice its tilted to the left and is difficult to push in and pull out plus it's squealing in the process.:frown1: Now what:confused:

Sooo,,What am I looking forward to now,,anyone had or done this before??

Sometimes this is depressing, I wanted to be driving this today

Hydraulic or mechanical?

If its tilted sounds like the bushings in the clutch pedal pivot may be shot or not seated properly.

I'd still look at the pivot point of the clutch pedal first. There are some plastic/nylon type bushings that the pedal is supposed to pivot on. Kinda the way a leaf spring is set up. Your tilting and squeaking would take me there first. If its binding up badly enough, it could certainly keep it from coming back up off the floor.
 
I disconnected it from the bell crank(z bar) earlier to test it. it's the pedal inside for sure.
 
I'm going to remove the pedal to see how it all works and replace what is broken. Anyone do this before? That return spring looks big and MEAN!:eek1:
The instructions I found:

CAUTION: Maintain pressure on lower arm. When lower attaching bolt is removed upper section will snap forward.

"SNAP'?:eek:

I'm kinda scared of snaps,,,Well, gotta get done. Then again,,that big spring sure is big,,,,Does it need to be that big???? I'm not liking this much....
 
OOPs,, read it wrong, "Snap upward".
Well,,nothing snapped at all! It's really bound up, and I don't know which way to pry to try to get that hugh spring off. Forward or backard? I'm worried about pulling the pivot shaft out with that evil spring attached.
ANY IDEAS??:confused:
 
I can turn the pivot shaft with a wrench, but its bound up and not coming out. I'm worried about the return spring being attached.

I'm really hoping Someone has replaced these bushings before and will offer advice, especially on disconnecting the return spring,,,Anyone?:confused:
 
Man, seriously? I have got to see this spring. Can you post a pic? But, lets face it, how bad can it be? You can overcome it with your leg, so its not like its a airbrake cylinder spring.
Now those will kill you if they get away, but this thing can't be that bad.
If it was, Mike Rowe would be featuring clutch pedal mechanics right along side the Time Bandit.

I'm guessing it hooks to something on the frame. Grab a pair of vice grips, and clamp down on a straight part and see if you can stretch it enough to unhook it.

I have changed leaf springs, coil springs on trucks, drum brake springs, air cylinder springs, watch springs, and the solenoid return spring on a Vendo Slant Shelf without pulling the stack.
Now that last one will hurt you if you aren't careful.

And other than the Vendo, the worst I have gotten hurt was when a bra strap caught me in the eye.

So, post a pic, grab a pair of vice grips, move the pedal all the way to the top to minimize the strain, and go for it.
 
For whatever reason, I don't remember any by nasty spring.:dunno:
 
I can't say that I have ever seen that spring before. Granted, all my clutches are hydraulic and its been a while since I worked on a mechanical.

It would appear that the side that the spring is on, is the same direction that the pedal is being pulled. Do you have a return spring down below on the "Z" bar? Seems like that spring may be causing your problems.

Someone else will chime in as to whether or not they are familiar with that one under the dash.

Can you disconnect everything underneath the truck and pull the pedal up to you closer to disconnect the spring in question?
 
There is a return spring on the zbar too, all thats disconnected now.
I can pull the arm up to a point, but it catches I think because the pressure the spring is putting on the crushed bushing and shaft, its tilted to the left. The shaft is also bound by the pressure and won't slide out.
I have tapped on it, but nervous about pounding on it.

I think the spring also is designed somehow to work both directions, so it works as a return to a point then kinda rolls and works to assist,,,if that makes sense.
 
Without being there and looking at it, I can't make much more for suggestions other than getting a screwdriver or small pry bar of sorts up in there and knucklin' up and getting it off teh ends. You can get pretty rough with the pedal and spring without worring about things. The items around the pedal are what ya got to be a little gentle with.
 
First of all, great pictures. We can see exactly whats going on.
In the first pic, it looks like there is some tension on the spring, but in the rest, it looks like the coils are either touching or almost touching.

I'm guessing that the pedal was in a different position for those. Remember, when those coils are touching, that spring is dead. Not enough power to do much of anything.

In the first picture, it seems to be hooked into a link, which is hooked over a mushroom headed stud.
It also looks like there is enough room for that link to slip over the head. If you can get to it, grab a big pair of Vice-Grips, clamp down on that link next to the spring hook, and pull the spring towards that stud and slip the link off.

If you can't get too it, or its still too strong, do this.
Find yourself some thin wooden wedges. If you have a miter saw, just cut a few. Wood will work best if its nice strong wood like Oak.
Or aluminum. You need something a little softer than the steel spring.

Get someone to press or pull on the pedal in whichever direction stretches the spring.
Then, press or tap in the wedges between the coils. If they are soft, the coils will bite into them and they will hold and not try to slip out.
Remember, you want a real gradual taper on the wedge. You don't want to use the wedge to drive the coils apart, they will already be apart, you just want them to fill the spaces between the coils.
Keeping a little pressure on the wedges with your hand, have them let off the pressure.
If that hole in the link is big enough, the spring should fall off. Otherwise, use the slack to unhook the hook.
 
I remember that spring. It's all bark and no bite. It hardly does anything at all... IIRC, you don't hardly notice a difference with it removed.
 
Well, I'm starting to worry......Did the spring get you????:eek1:
 
that spring is just plane and nasty... my father had to put it on for me.. he is alot bigger than me... that spring is veeeeeeery strong... that is why the mech clutch setups hurt your leg in traffic... now im hydraulic and never took that spring out... :popcorn:
