The coldest i experienced was in Rangley Maine back in early 90's was -45 degrees. I could not get into my car because the doors were frozen shut. When it warmed up to -20 a few days later, I was able to drive my sled in to town. I would cut across Rangley lake to get there. Looking back.... I would like to do that again... but I have been in N.C. 20 years, so Im probably a wimp now...

It was probably a lot colder in upper Vermont>> And Maine and upstate New York!!

Because, they know we just gave away any moral high ground, we didn't loose it, we gave it away. They are thrilled.

For some reason I’ve got this feeling that Trump Putin and Xi have a 3 way territorial deal. USA takes control of Venezuela. USA cuts off Ukraine support and Russia takes control of Ukraine. And finally China invades and takes control of Taiwan and USA looks the other way. Iran and Greenland are just distractions. i don’t know why I have that thought but it just seems like Russia and China were way too quite when we took control of the Venezuelan government. dunno.

“I may do that for Greenland too,” Trump said. “I may put a tariff on countries if they don’t go along with Greenland, because we need Greenland for national security. So I may do that.” I honestly can’t believe this Greenland thing is going down. It’s actually quite embarrassing in my opinion. The rest of the world has to be looking at this in total disbelief as well. Trump casually tried this back in 2019 and Denmark told him to kick rocks. Sounds to me like ownership is not even up for discussion. If he wants to make some other kind of security or minerals deal I don’t think this threatening demeanor is going to get us very far. This country is using up whatever good will it had left with the rest of the world at a very rapid clip.

During his first term, Trump formed an Arctic working group that deepened his understanding of Greenland's geo-strategic importance—and highlighted concerns about Canada's Arctic vulnerabilities. https://www.dailymail.co.uk/news/article-15471249/Trump-Greenland-Canada-Donroe-Doctrine.html

Right under the front of injection pump, has two fuel lines on the bottom of it, with two capscrews with copper washers on the top of it, take the nuts off and there is a plastic check valve under each one. You can see the top of it on the last pic. terry also a small spring on each one

Ah grasshopper, special air drier made for Mack mechanic, not for IHC man!😄

I see the AD-IS.. thats like the one I was suggesting. The one I called an AD-6. I dont think I made up that unit number, however..... who knows ? 😄

Turns out desiccant for the AD-2 is available: AD-2 desiccant

🤔

not exactly sure where that is. I am not a heavy truck mechanic and still learning my truck all beit it is older

Never heard of one, and the internet doesn't return any hits. is a AD-IS? that take a spin-on cartridge. there is AD-SP which is Bendix version of the Meritor spin-on and requires purge air from the secondary air tank. The early air driers have internal purge volume, so don't need extra tanks or a SC-PR valve (a check valve that allow a set amount of air back to purge the drier. With air start trucks, I wanted to make sure my air was dry. The AD-4 did that for me and didn't need a lot of baby sitting. I had 2 AD-9's fail, and I swore I wouldn't have another. One the threads in the base failed, the other the outlet check failed.

I forgot to add that those are chunks of chicken in there, picked off the boiled trimmings. I also skim the fat off the top when it cools, and use it to fry some of my meals, like burritos for example..

The AD-6 is a spin on. I use my Cat oil filter tool to replace them. To me, very easy to maintain.. all good..

I doubt the AD-2 is the problem. I have one that is still going fine. I'd put my money into replacing hoses before I touched the air drier. When I scrap the Fleetstar with the AD-2, it is going on my K-7, only drier that will fit behind the cab under the body. I took off all newer driers (AD-9 and Rockwell/Meritor) and installed AD-4's. Even converted some AD-9's into AD-4's with the addition of a plate and base. The older driers are a pain to service compared to a "spin on" or single bolt (AD-9) but will out last them hands down. If you take care of the air system, so it is not popping off all the time, an air drier will go years perhaps decades without being serviced (yes, I know decades is not recommended). When you start to see moisture out of the wet tank, then look at the air drier, if the rest of the system is up to snuff.

GW ? What do you think about ditching that old one and installing either an AD-6 or an ADIP model. I prefer the AD-6..

lately I haven't been getting anything out of the purge valve when the system reaches 120. I agree that the line between compressor and dryer should be replaced. It is definitely on the list of things to do with this truck. Right now I am also fight a fuel problem which I am hoping is old/bad fuel lines. The truck was never maintained as it should of been when my dad was operating the business and then sat for 20 yrs before I opted to put it back into service

So.... Heres a twist. something my wife and I have been doing for years. When I trim chicken parts, I make stock.. Then add in frozen pee's, carrots, green beans, broccoli, and cauliflower, or combinations of them. this time its pee's and carrots... We mix this into our Pup's dry food..... They go nut's over it..

The vast majority of the time when a vehicle has trouble "building" air, the problem is it is having trouble holding on to the air that has been compressed into the system. A system that has a true "building air" problem, will hold the air just fine after the cut-out pressure is reached, it will hold at 120 psi with the compressor unloaded for a long time. Much more common is for the system to rapidly loose pressure, start compressing again, then loose it once the compressor unloads. Check for air leaking out of the purge valve on the bottom of the drier when the compressor is active. You should get a burst of air followed by a slow release of air out the purge valve when the compressor unloads. A leaky air line between compressor and drier will act the same. A leak after the drier will cause rapid cycling of the compressor.

i am working on replacing most of the lines one by one on this truck being it is a 1979. I know rubber breaks down just from age (not alot of miles but 47 yrs old) and this truck has seen alot of road salt. The problem I am having is that once it got cold the truck had a hard time building air. I replaced the governor which seemed to help a bit. Air pump was replaced about 5 or 6 years ago. Being a garbage truck it does alot of start and stopping.
