How can you lell from the drivers seat if your mirrors are tight and secure. You have to grab them from the outside of the vehicle to make sure the mounting bolts are grabbing. Looking in the mirror from the drivers seat does not tell you that
Its my opinion your a crook. All my comments have been deleted. Im sorry im a licensed mechamic but learn what i tell you and teach it. Delete this one too if you want
Wet tank is the tank the gets fed off your comprrssor or air dryer. Primary and seconday can be a bit confussing as some are combined into one with a double check valve in between the too but depending on the number of brake chambers that dictates the total air volume that needs to be stored and hence the total number of air tanks
I'm a licensed mechanic. Your cut out and cut in pressures are dictated by the mechanical design of the governor on the compressor. It's mechanically set to 25 psi from your cut out pressure. Only the cut out pressure is adjustable. If you set the cut out pressure to 150 psi which is standard for coaches and 120 psi for trucks... the cut in pressures will be 125 for coaches and 95 for trucks. Anything else is bad.
❤❤thanks jazz you help me here in Ottawa. I watched this video 4yrs ago and it REALLY helped me on the test. I appreciate the well done work you guys produced here
As a Certified Evaluator and Instructor with almost 50 years of trucking, what I can tell you based on what I have seen, is you get the gist of it. Would you fail, No. Failure is a lesson to be learned and an opportunity to understand what you're missing, or may not have known, or, your complacency, has allowed you to miss a step, without thinking of the repercussions down the road,. Personally, I'd offer a 1-hour course to refresh your memory. With no airbags on your truck, you did good on height, when dropping the trailer, but what would you have done if a driver before you dropped that trailer loaded and it was just below the transom. I would rate this video a 7/10--- good job
When you "Uncouple" or "Couple" to a trailer, you DO NOT remove the air/electrical lines until "AFTER" the power unit clears the trailer, and is still able to support the trailer after disconnection. Your 3-point Contact is terrible. The grease on that 5th Wheel is terrible. The overflow is hanging over the 5th wheel, which is way too much for the 5th wheel and its purpose. The area to the front of the 5th wheel shows rust from improper lack of placement of the grease. I should place a timer on the areas that are not good. But bringing the power unit to the trailer is good, and making sure everything is safe to back under is good, BUT, it is from that time, that you need to hook up the lines. Once that is done, you can go back into the cab, apply the brakes, release the trailer brakes and watch your "Secondary Air Gauge" which will tell you if the trailer is charging. Once you have done that, re-apply the trailer brakes, listen for the exhaust. Once you hear that very audible release of air, that is your indicator that the trailer spring brakes are charged and ready for hookup. Then you may go under and hook up. Don't worry about the shift of the trailer, you normally never hit the kingpin straight on. Once you hear the clank of the Locking Bar, you then give 2 good tugs to be sure you are hooked up. And don't be tender-footed, pull and hold for a second on both tugs. There is no better time for separation than at that point.
My question is, what do you do, "IF" you don't have wheel chalks or block, available? If you're running a day-cab, you have no place to safely secure, what can you do? Talking to an examiner is for when you are getting into trucking. What should you do, when you have a Class A and you are "Coupling and Uncoupling", forget the examiner. If you are "unable" to unlock or pull the locking arm out, it has nothing to do with friction. And has everything to do with the position of the 5th wheel. Your best route when you're about to uncouple is to take the pressure "AWAY" from the jaws or locking arm. Just get back into the cab put it in reverse and take the pressure away from the jaws. On that catwalk, ( mind you what you do in your yard is your business, but as soon as you drive on that road, it is yours and theirs) bungee cords are illegal and placement of the line is not allowed. It is why truck manufacturers, have a Lines Holder on the back of the cab. I know that this is all for "How To", but if you're going to show how it is done, please make sure, they understand the rules.
