Technical Heard a bang, pedal sunk!

Hey everyone. Just went for a glorious first drive of the year and after parking, started it up once more. It's a 1954 Chevy 3100.

Gave a little gas.... and BANG! - then the throttle pedal sunk to the floor with no resistance. When I look in the engine bay, it appears (I'm a total newbie) that something has broken where the rod meets the throttle linkage. Ie: no matter what I do with the pedal now, I'm getting no action in the mechanism.

Any ideas - has this happened to anyone else? Replacement parts I might need?

 

I hope this works out OK. But surely you realize that you just have to crawl in there, figure it out, and then fix it.

 

Picture of the linkage? I don’t have a 54 Chevy here to look at.

Look on the side of the block down and back of the carburetor, there is a pivot point there, one rod goes up to the carburetor and the other goes to the foot feed.

 

I would be curious as to what the BANG was.

 

Call a mechanic .throttle work is not for the newbie ,it can kill you or anyone nearby.

 

Pedal return spring broke.

 

Thanks everyone. Yeah got in there and discovered it was indeed pretty grimey (first pic) after cleaning it up, and working the mechanism by hand, it's suddenly returned to a nice fluid motion. I will say the image with the yellow circle... Should that be a little more snug? There's a quite a bit of side-to-side movement in it. Thanks for the help.

 

That slop is typical, and probably is not hurting anything.

Does the car have a Powerglide transmission?

 

The slop can be taken out by installing a flat washer or 2 behind the split pin on the other side. Don't forget to grease it up.

 

Hydromatic transmission. That's all I know :/

 

Thanks so much!
