You have leaks, fix them. Speed of fill makes no difference. You just couldn't hear them over the engine before
Did not use the red side. Wheel chocks are now on the list, thank you for that.You have leaks, fix them. Speed of fill makes no difference. You just couldn't hear them over the engine before
did you add air thru the front red glad-hand? If so, be careful, that also releases the park brakes, so chock the wheels…
So where exactly did you connect the air to?
I have it hooked up to the blue side.
Wade into your rebuild of your truck slowly. Ask lots of questions. The diaphragms in the air brake cans can be replaced, BUT doing them without working knowledge can kill you. The springs inside are so powerful they can easily crush a face. Better to replace. There are miles of air lines on these trucks. The lines get brittle, especially when the plastic is exposed to compressed air oil. Replace whenever possible. Label your lines as you go. Label the valves too. Use industrial dymo tape or a paint pen NOT perm markers. Markers fade. If you break down, those labels will be a blessing. Use soapy water to find leaks. I used of few field replaceable brass connectors when I rebuilt mine. I have used a smoke machine on some lines too. The cab air ride bags leak at lot. They wear at their fold at the rubber bladder at the bottom. Replace with Power Pack components or new modded version.
Soapy water. Freaking genius! I’m working on things I can see, fixing what looks old (everything looks old). This truck is so cool but man was it neglected. And after yesterday, hearing the air leaks, it’s shined a light onto what I can’t see, or hear.
I don’t know a ton about the air system but I did this on my truck and you are supposed to connect to the red glad hand. That should fill the tanks quick but also will remove the parking brake. I could be wrong but I feel like your tanks filling up off the blue side would indicate failing check valves. My understanding is those are commonly corroded.
To all of you. Thanks. I had no idea about check valves. And procedure for releasing air breaks. I have the operation manual. And all the PDF files. But most of this stuff I am not finding in a book. It’s all from the people that drive them.
Eco Hubs! Cut your driveline speed in half. Greatly reduce noise. Increase fuel efficiency. I know sounds like a sales pitch!
Ok, you were applying the brakes. If the tanks filled, you have a bad check somewhere backfeeding the tanks...
I start with my ears first, so you need outside air and quiet, without the kitty purring. then I feel along every line, over every fitting with fingertips. Then I bubble the fittings/unions. Of course you need to create the specific conditions where the particular lines are actually carrying air...
The only issue with putting the female end on the truck is that it fills with road grime and also pretty quickly corrodes, Mine sure has(not meant to be out in the weather).Throw an air chuck quick connect on the wet tank and make an appropriate adapter to connect to your compressor. This also allows you to run air tools when the motor is running.
Random example of internet:
Super easy mod and a very handy and practical feature! Just wrench the two male connectors together to make an adapter to allow the standard hose to attach to the tank. My adapter rides in the battery box for if it's ever needed. Otherwise, a standard air hose now connects up easily.
