No longer Stranded in Kansas with Air Brake Issue

[thesledge]

We have made it about 100 miles with no issues but just started loosing brake pressure. We got stopped and bled the system however, it will not fill all the way back up... Help!!! Thoughts!!! Give me a call if you could walk me through some troubleshooting...

It's an M923A2

Check your air dryer see if it leaks as the pressure builds up the other possibility is the compressor governer may be going bad.

Where exactly are you? 100 miles should put you near Glen, and any parts you might need.

 

[camoyj7]

If you hear air leaking from air dryer it's most likely froze

 

[doghead]

Did you air up and drain everything before heading out?

Did you bring an air dryer service kit?

The last time I was in a convoy to a MV event the 932 I was with went down for a clogged air dryer. He lost pressure and it would not build until he paid a mobile mech to bypass it.

 

[FMJ]

Are there any updates?

 

[thesledge]

Guys, I think we got it figured out thanks to a call from another SS member!!! Thanks Paul! We were able to track down a air governor. After talking with Paul, it made sense that this is the issue. On the way back to the truck which is 20 miles west of Hays, Kansas. Will update again hopefully with good news. Thanks for all your help guys.

... On the way back to the truck which is 20 miles west of Hays, Kansas. ...

Hayes, KS!!! That's where the transmission, for which you are hauling the replacement, started going out. That's also where my deuce skidded off the road in the rain when I picked it up at Riley 7 years ago.

We're anxiously awaiting news.

I told you wrong, there's weather coming your way. You will probably see light snow by noon.

 

[thesledge]

Well, we are back on the road and I can't wait to take a picture in the morning of what we did to get her back up and going. Lets just start with saying it involved 2 trips back and forth to Hays, Kansas and a $700 trip to Home Depot for a generator (decided last minute to leave mine at home) and an air compressor (once again, left mine at home). Oh well, we are closer to home now than we were. So, please pray that we make it home safely tonight with no further complications.

Made it home! Off to bed.

I am very curious as to why you had to resort to a generator running an electric air compressor. Glad you made it home safe, update us when you can. Curious minds want to know...

I have also experienced the air drier issue. A bunch of spray kroil and repeated cycling got it working right.

 

[doghead]

I'm guessing it was not the air governor.

I'm guessing he did not bring an air dryer service kit.

I'm guessing...

 

[KaiserM109]

I'm guessing he had a generator and an air compressor running in the back patched in into the truck's air.

Hey Guys. Well, yes, we ended up using the generator and compressor to supply air to the brake system right at the air dryer. This kept the system around 80psi and we had brakes for the remaining 300 mile trip home. However, as we got about 50 miles from home suddenly my windshield wipers cycled and the system went up to 110 psi. This was certainly perplexing to me at 4am this morning after having been up for 24 hours. The hose where we disconnected the dryer was obviously still disconnected and and yet it was still keeping 110 psi. However, all of the lower pressure items were working properly (horn, wipers). Anyways, I am not so sure that I am glad that it is working because I dont know what the problem was... Maybe something just had to get worked out of the system. Maybe some rust was in the lines, etc... We did drive through a terrible blizzard for about 100 miles and most everything under the truck was frozen, so that could have had some effect on helping break something free. Just a thought though. So, I am going to hook up the main supply line later today and see if it builds pressure normally. We had also changed the air governor before going the route of the generator/compressor and it did not resolve the issue. Anyways, it was a successful trip as we got home safely.

 

[ranchhopper]

Those governers have to be adjusted you can raise or lower the air pressure by turning a screw on the top.

Glad you made it home safe despite the issue and the freak horizontal snow storm. Hope to see the truck around town some time.

 

[KaiserM109]

You get the Farmer's Association's Golden Bailing Wire Award for that work! I'm impressed and glad you're back home with all your equipment in your own yard.

This tells me that I need to get a lot more familiar with how the air system works on my truck.

I’m real glad you’re home and all your equipment is in your own yard. I’ll talk to you later about that transmission and the two tires you’re hauling from Glen’s place. I was sure impressed with dealing with Glen (91W350) at BFR Metals. He PM’d me this morning asking about you.

follow that

Made it home! Off to bed.

Well done..that was nailbiting(!) followinmg your exploit. Looks like you could (now) adopt my motto "we are the kiddies,we HAVE the techno, we can NOT be beat". Well done. Now you can start and enjoy your new aquisition.
