Hey,
I was moving snow in Colorado tonight, and one time when I pushed the clutch in, the pedal went straight to the floor, there was a ping from under the truck and it stayed in gear. I just pulled it out of gear and found the piece that came off in the snow. It was the strange looking tip of number 14 in the diagram below.

I did the clutch on this truck 1.5 years ago and everything has been fine, but now there is not enough tension between the clutch fork and the release rod to hold the pedal out away from the floor board. Spring #18 and the spring that connects to the clutch fork are there and intact.

I am at a bit of a loss and I am praying that it is not the actual springs in the clutch. Maybe these external ones are worn out?

Thoughts anyone? Do you think there is any significant risk to using those adjustment bolts to try to remove the slop?

 

I just had a similar issue happen yesterday on my 77 f250, yet i still have just enough return to let the pedal all the way out, i can get the truck to drive but if i try climbing a hill or accelerating hard the engine revs as if it is in neutral. When i pushed the clutch in to take it out of gear to start it, i heard a pop and the pedal is now very very soft.. Everything external is intact and operating fine.. I do not have an inspection plate though to see inside the bellhousing.. Any more info on this problem would be greatly appreciated..

 

Loyadable not sure what you have going wrong. Might try to adjust it?

Cody when it revs up do you smell burnt clutch? If so, your clutch is worn out or WAY out of adjustment. You might get away with making an adjustment?

 

Here is how mine looks mud, grease, rust and all.

 

I'll try to adjust it this morning. Thanks for all the info. It could be the spring on the clutch fork, but I think If I back those bolts about an inch forward, I might be able to finish the work and wait for better weather. 7 degrees right now and a pile of snow under the truck. Fun fun! In fact, I got all confused seeing that green grass under your truck

 

A 4x8 sheet pf plywood will let your wheely creeper still roll like a BOSS under there. lol

 

These are notorious for flopping out without notice.. It should be a regular maintenance item to check. I had one come off in the driveway, thankfully I wasn't at a red light behind someone

 

You can always take some wire and make a loop around one threaded end of the clutch adjustment rod and then twist it up and tie it off on the other side of the threaded arm....Safety wire it in place so to speak.

Or put a self locking nut on the end?

 

Thanks for all of the advice and help everyone! It ended up being that the linkage between the pedal and the clutch assembly, the "clutch rod" had gotten week on the pedal side and the 90 degree medal piece tore off the rest of the rod. A little weld and I had it going again. Just didn't notice it hanging there at night.

 

Actually there is NO clutch adjustment on these old trucks. The only thing you do is move the throw-out bearing in, riding on the pressure plate fingers and possibly cause the clutch to slip, or moving it out and keeping the clutch from disengaging. If your clutch starts slipping and you havent moved the rod through any adjustments you can turn it to your hearts content and it wont solve a thing. Might make you feel better but wont stop a clutch from slipping.

 

I have had the same thing happen before. I usually cut the end off square and then thread the end of the rod. Then you can use an appropriately sized swivel rod end on it. It won't wear as quick as the end with the 90 degree bend and cotter pin. Have done it on dents as well as older Jeeps. Works great.

 

77&79F250.......Are your brake lines rubbing on the "Z" bar in your pics?? I can't tell for sure but may be something to take a look at..........Just an observation......
