03 Peterbilt 379 Fifth wheel slide solenoid

Not to hijack your post, But...I don't even use mine anymore. Just seemed to take longer than just manually pulling it. It's not like I have to get out to do that one thing. I'm already there disconnecting lines and dropping the landing gear...

 

An 03 pete i don't think there is a solenoid. It's just the switch on the dash. Assume it's an air switch?

 

Do you need to move it, or just want to? Is weight a concern? As nasty as that slider plate looks, it's all probably rusted together anyway.

I'd clean that off and spray some penetrating oil around the locking pins.

Then figure out your air issue.

 

You can disconnect the air line by the cylinder and connect an air line there bypassing everything else. Your pins should retract then allowing you to manually put it where you want.
Once you disconnect the temporary air the pins will retract and you should be good to go.
That’s what I did when I couldn’t find the lack of air problem.

 

Ooops...I misread the topic. I thought you meant the air release for the jaws.
