You really earn your name, B K G, on these hoses especially those hard plastic def coolant lines. I saw the soft line off the compressor full of carbon before. It had a pencil eraser size hole in middle causing slow air build if I remember right. You got a neat way of explaining your work. Great channel!
Why don’t you like me bro? Hahahahha. Love your videos. I’m in the same boat as you but I’m fleet. I like to see how you fix things and how we do it. Your a boss. Cheers
Thanks for the positive feedback man. We want that $$ we gotta learn somehow right. Infact you have been chosen to be the new cameraman. Drop that fleet and move to Az. Also it only pays free sodas.
great video. with your experience how often should my air dryer purge?. at idle with the cruise control on my airdryer is purging every 5 minutes. even when i go down the road without using my brakes it's still purges every 5 minutes. im pretty sure that is not normal.
Thanks for watching and reaching out. This would be a tough one. Wabco the air drier manufacturer would say it’s normal. But, I would say if your cruising along it shouldn’t purge unless ur losing air from somewhere. You have an air leak, slow enough to cause a long delay between purges. Best thing to do is use soapy water and find all your leaks.
Thanks for reaching out. UTI is where I went but I’m sure you can do it without the school and just do on the job training. Fleet shops are great for that.
I replaced my air compressor and it started leaking oil and air leak from the hard discharge line . I replaced the hardline and the soft line and it still doing it again air leak and oil do you know what can it be maybe a bad air dryer? Thank you for the videos 🙏!!
Thanks for reaching out. If you just replaced your air comp and it’s leaking both air and oil your best bet is to pull it back off and check your seals. One is probably not seated right. As for air leak it usually the small signal line. Just get some soapy water and find the source.
That’s exactly why I needed both. If you want heat it up with a torch and while using a back up wrench it should get free. In rare cases I have to cut them off and replace the line and fitting. But not often at all.
@@bustedknucklebydieseldr3228 thanks it took me 2 days of trying to turn it and a lot of wd 40 but the second day it came off with no issue just rusted/dirt stopping it from turning
Hey bro sorry to bother you gain I have a question that Ive been loosing sleep over. Hopefully you can get to my question.. Ok quick explanation. I just replaced the new air compressor on my 2012 cascade dd15, everything went smooth for about a week after, but one morning my "new" compressor just wouldn't build pressure past 50-55 psi. Finally after 20-25 minutes of reving the engine I finally got to build pressure. I push both parking knobs(red and yellow)and I let the air stabilize before taking off, well now the freakin compressor won't build air or maintain air to get me going. I already replaced air compressor(aftermarket but new) changed the air governor, changed the check valves on tanks, and still having the same problem. I honestly don't know what to do at this point. I compared the compressor air pressure with my brothers dd15 and they both feel identical to me. I hope im being clear enough so that you can kinda point me in a direction. BTW, I don't hear any extremely noticeable air leaks. PLEASE HELP!!!! God bless bro!!
@@alexkalinin9188 I did fix it bro. Even though it was a brand new compressor, and with out any more options I decided to replace the UNLOADER VALVE as my last option and booom. That was the fix. Brand new compressor with a bad Unloader valve, happy damn!!!
I had a grill to rear end rebuild last year at detroit. I wanted the warranty as im old now and hope this is my last one. I'm on my 3rd bendix compressor under warranty. First 2 putting out oil like a big dog. Number 3 was good for 7 months. Slow building secondary air. Then no secondary air at all. I put a dryer on. Then governor cuts compressor out,purge valve leaks till compressor cuts in again. Long story,loaders bad in 7 month old compressor. New parts are crap. Oem or aftermarket.
bro i had international Prostar, when i dive 30 minutes air is losing when i push brake air is build back again all shops including dealer cannot find issue, where is you're location thanks for you're information
Sooo. Like a dumb a** I fought everything in the way and didn’t take off the mudguard for three days. I wish I would’ve watched this before hand. This fix was NOT fun. Glad I did it myself but wish I did it smart.
Hey how you doing I got an issue with my secondary air pausing around 60 psi for a few seconds, for some reason it's longer in the colder weather. I have a video wish i could send it to you. Any advice on my issue, I already changed the air compressor. TIA.
Thanks for reaching out. For issues with air pressure build up I’d go right to the wet tank. The check valve in there often gets plugged up and causes this very issue. Air compressor won’t help this concern but don’t for get to do regular air drier cartridge maintenance.
@Busted knuckle by diesel dr Thank you that is the next step I've been researching about. Saw one video that showed the check valve getting stuck due to moisture and corrosion. Thanks alot I just needed someone with your knowledge to make sure that was the next step to take. Thank you 👍🙏
I really appreciate your your videos bro. Question. If I start having oil in the dryer, and on that discharge line? Does that mean it’s time for a new compressor? Or is it a matter of chafing gaskets etc etc?? Thanx again chief!!!
Thanks for reaching out. If you have oil coming out the air drier than Deff it’s time for a air compressor replacement. If it’s just moisture coming out and your discharge line looks oily than it’s still good. Although I’d replace your drier cartridge if it hasent been done in a year. Fills up fast. And the line will look that way as it’s super heated air that cools off the carbon build up inside sweats and cools through the hose to mimick oil. Hope that helps clear some things up.
@@bustedknucklebydieseldr3228 Thank you for your prompt response brotha!! Im getting close to 1M on the factory compressor. I think im just going swap it before it leaves me stranded in the middle of nowhere, worst yet In the middle of the freakin city with all that traffic. Appreciate ya brotha....
Great question man. Technically Yes, the wetness is from super heated air going through the discharge line and turning to carbon when cooled causeing a sweating effect on the outside of the line. Thanks for watching man

Looking good boss. Great work there. I am having problems with high air pressure on the gauges. I did put new air dryer, new break chambers and new couple houses but still the air on the gauges are too high…150psi and above. I did not check those lines connected to the compressor and also didn’t check the unloader kit/valve. Need your help or shop… where and when? Thanks.
Thanks for watching and reaching out. Today is your lucky day. Knowledge that is completely free. Like a cereal box with a toy inside. With air pressure gauges going to high past 125 psi. I would recommend replacing the part that controls the cut out pressure. Which is a air governor located on your air drier. Unless your truck is very old pre 2014 than it’ll be on d/s of eng block by the engine ecm. There’s a lot of tests you can do but 99% of the time it leads to air governor replacement. Good luck and give it a try yourself. You’ll save so much $$ than taking it in anywhere. Stay safe out there.
@@bustedknucklebydieseldr3228 thanks. I end up finding a cracked outline. Fixed it. After two days, now I keep losing air while driving. I have to pull over, stop and rebuild air again and again. Found out the purge valve on the air dryer is broken and it leaks. 2014 freight liner.
I noticed the forward soft line is wet with oil. Mine is the same, is this an issue? I was told that is just bypass oil. Should I be planning to replace the compressor soon? Are they rebuildable? Thanks for the video!
Thanks for watching and reaching out. Can’t do without you guys. As for that air compressor discharge line it is super heated air coming from the compressor cooling off and sweating the carbon that’s been built up in the line. Giving it the presence of oil leaking. There is only cause for concern when the air dryer is purging out oil then you know your compressor is bad. Hope that helps

Thanks for the positive feedback man. You watching my videos is much appreciated. Stay motivated and stay safe out there
Thank you so for this video bro i really change it myself yesterday I didn't know what to do until I saw your video
Glad this vid came in handy for you. Hopefully more vids on this channel prove to be useful and save you $$. Stay safe out there.
Very educational bro. You build my confidence. Thnx for the channel.
This guy saved me a lot of money as owner op
Glad I could help. It’s all about saving that money and trying it yourself. Hopefully more vids on this channel prove useful.
Have the same problem I thought it was diesel line 😅 thanks my brother it's only air right,, thanks mr dr diesel.

I had this same issue and two shops tried to say I needed an air compressor. Long story short I ended up changing it myself
Thanks for adding the pricing.
Every shop has the same songs on I swear😂😂😂
You are a big help thank you
Thanks great video help me get to my problem without paying in V Clinton SC 🎉
Thank you
Man you need to do more videos lol I be waiting for you to drop a video lol
I know when you was pointing you wanted to do 2 in the pink and one in the stink. I can read your mind! Hahahhahah
How do you get the first unscrewed by the front engine I can’t get in there?
If this line is leaking can it cause low power issues
Great Video, my Kind of style. What do you use to edit final product?
Thanks for the positive feedback pic play post for the most part.
This was the exact issue with my truck.

Did you need to use the 2 wrenches so it would hold the pipe side still? Mine won’t budge and i don’t want to snap the pipe side

Check your parking and emergency lines that connect to the trailer, they might be leaking.
Hi where can I find air governor on the 2020 cascadia dd15
2020s have them mounted to the air drier itself.

How much for labor
If you’re doing just the line at the compressor expect to pay about 3 hrs of the shop rate.
I sure do miss Diesel Doctor. I hope he’s ok. Come back to TH-cam

Is the wetness on the hose oil? Does it come from the air compressor?
Great question man. Technically Yes, the wetness is from super heated air going through the discharge line and turning to carbon when cooled causeing a sweating effect on the outside of the line.
Thanks for watching man
@@bustedknucklebydieseldr3228
Thank you.
Hello! Do you have a part number by any chance?
I would say contact your local dealer for the vin specific part number. Depending on what year you have the line changes size and part number.
How long does it normally take to change?
If it’s just the soft line than it should only be about 1.5 hrs. Now what it pays is about 3.5 depending on application.
Thy..good clip..
Can this be one of the things causing my air to build slowly?
Great question and yes this can be one contributing factor for slow building air.
Im going thru this now. Found out last night where its leaking from
Hope this video helps some now.
Could you hear the leak ?
Could you hear the leak ?
Thanks for watching and reaching out. Majority of the time you can hear this type of leak. Tell tale sign is hard to build air.
Bro why soft line is wet near air dryer?
Great question man. Technically Yes, the wetness is from super heated air going through the discharge line and turning to carbon when cooled causeing a sweating effect on the outside of the line.
