please I need your help :)

@AModelCat- wake up!

 

They go in your truck’s sleeper.

Not sure what the top one is, the 2nd is for the soda fountain in your sleeper, not sure the 3rd one, the 4th is a toilet plunger, bottom one is a tv dinner.

 

#1 Unknown. Just a shot in the dark as I havent held one. Parking brake controller for the dash?
#2 appears to be a airbrake valve. Yet I have only seen them on older alcoa diesel locomotives. It could be for a older Mack Model B?
#3 appears to be a slack adjuster for the brakes yet usuallly slack adjusters dont have bearings inside as they clamp to the S cam for the brakes.
#4 is an air brake cannister. The long part with the plastic wrapping pointing to the left is what attaches to the slack adjuster.
#5 is pressed steel for a Mercedes, but with out more pictures I cant say what it is, perhaps a rocker cover for a Mercedes engine?

Maybe @rank or @wore out could help better with mechanical parts

 

Hello,
Many questions, please respond.
Are these parts bad on your truck now?
How did you determine this?
Where did these new parts come from?
3 and 4 are brake components.
Is your truck Mercedes?

 

I am thinking it is part of a quiz somewhere and the person is to show their intelligence of truck knowledge.

 

number 1 part has a Wabco part tag.
What is the number stamped on it?
All these parts have a number on them.
Pictures without these numbers is guessing.
Please supply P/N's.

 

Probably that is part of the quiz. to give best educated guess
