Pop Quiz Question

I have a pop quiz question for those studying and or in school.

My neighbor is a o/o and has 3 trucks. He started up one of his trucks and it has been sitting here idling for 20 minutes. I noticed it makes a "psssh" sound every 2 to 3 minutes.

What is happening and is it correct?

Your, "psssh" may vary but based on your description it sounds like a release valve releasing air once the air tanks are at full pressure. This is normal.

They are air system pressure tank farts.

I don't think he was asking because he didn't know.

This is normal.

Not every "two to three minutes." If this is normal for you, you need a better maintenance program.

Banks, good point.

That’s why I like these “pop quizzes” because someone is trying to be an educator.

Keep ‘em coming!

You picked up on what I was getting at. I was hoping someone in school or just out of it would be able to pick up on it. But oh well

Yeah, sorry, the thread immediately ran off the rails, so was trying to bring it back to what you were looking for without actually giving away the answer.

Judge: The jury will disregard the witnesses answer. Lol

I'm in trucking school right now and this is what out training tractor does. Makes that sound every few minutes.

Then again our tractor is all ****ed up so it probably shouldn't do that.
