mechanical clutch questions
i have a 1983 F-100 with a mechanical clutch. recently I've noticed the clutch wont return to the "top" of where it normal sits rather staying just above where the clutch will be fully engaged with the transmission. I've removed said assembly and have found no damage to the assembly as is. As far as I can tell the system has 2 spring - one on the pedal assembly and the other down by the clutch fork. nothing is bent or missing that I can tell of the rods, clutch fork and adjustment screw. I was going to replace the return spring but am confused to as which spring controls the full return of the clutch pedal. I haven't quite figured out how to add pictures but once I do I will add those. Any help is greatly appreciated.

To add pictures, click the "Go Advanced" button next to the post quick reply button, you'll see a "paper clip" in the tool bar in the post box. click on the paper clip. it should take you to another page where you can view your pictures. Just noticed, when you edit your post that paper clip is there too.

I would get under there with a flashlight, and work the pedal up and down the amount you want it to raise up, and see what could possibly be causing it. If the spring is obviously broke, I would replace it. But it's not a common problem with these trucks.
P.S. Check the other spring underneath also. Get someone to work the pedal while you are underneath the truck with the light.

Welcome to my world and because I am lazy I just pull it up with my toe and yes I know my linkage is good as I rebuilt it.
Now that top spring #7534? is called over center spring and from what I have found on other makes & models it is to bring the pedal back up but in all of mine it dose not
Now if you look at the lower spring #7523 that Dave said is to take the play out look at where it is hooked to at both ends.
1 end is to the clutch fork pulling it to the adjuster and keeping it from falling out and apart.
The other end is to the frame and pulls the linkage and pedal back up to top.
I did not know this when I put mine together so the spring I have goes from the fork to the cross bar #7528 to keep the adjuster from falling out.
For you if it is not to the frame then hook it to the frame and if it is then I am thinking the spring got weak and may need to be changed out.
Heck I did not even think of looking at it when I greased the truck 2 weeks ago as I was right there greasing the over drive shifter

I think you will find that if you lengthen the push-rod adjuster slightly (7A504 in the parts diagram), your pedal will return to the upper stop.....assuming your pedal springs are intact.
My experience is that if the push-rod is too short, the pedal will lift but not pop up fully.

I have my dash apart currently and noticed that there's a wiring harness laying on top of the spring in the pedal cluster. When I re-assemble the dash, I'm going to make sure that harness is pulled up and away from the spring (by using a zip tie or safety wire). Be careful with adjusting the push-rod under the truck. Lengthening it too much can cause premature clutch disc wear (because the clutch is now slipping, slightly).

I dont want to adjust the clutch because of that and I like were it grabs.
When I was working, truck driver, I hated when the truck went in for service and they would adjust the clutch.
It would take a while to get use to it as you only used the clutch for starting and stopping all the gear changes are with out a clutch, 10 sp truck transmission.
