dirtrunner0519 Posted November 4, 2020 Report Share Posted November 4, 2020 Good Morning Everyone, I have a Kenworth T2000 that will not currently build air. I know that the compressor is working but there is a leak on a valve towards the middle of the frame just before the axles. I cannot read the info on the valve. Does anyone know what this is? In addition, does anyone have a parts manual or service manual for this beast, just to help me identify parts so I can order new ones? I have attached some updated photos of the build progress it is not longer ugly red it is now monster lined grey with a 14' box that will soon be converted into more of a living quarters.

Darryl&Rita Posted November 4, 2020 Report Share Posted November 4, 2020 (edited) Nice pic, doesn't help identify the part, though. That location sounds like either air suspension, or brakes.

Thats one heck of a moose bumper. Is it easy to open the hood for pre-ride inspections? Quote Link to comment Share on other sites More sharing options...

Even a better description of the lines going to/from said valve will help. Does the leakage start immediately, or does the pressure build some, before leaking starts? Brake leaks will begin as soon as pressure starts to build, but suspension leaks will only begin after 40-60 psi builds up in the system. 9 minutes ago, spindrift said: Leveling valve?? Very possible. See last sentence, above.

dirtrunner0519 Posted November 4, 2020 Author Report Share Posted November 4, 2020 It pretty much straight away starts starts to leak at the valve and will not start building. Quote Link to comment Share on other sites More sharing options...
Parrformance Posted November 4, 2020 Report Share Posted November 4, 2020 Do the two outbound lines go to brake chambers, or air bags?

dirtrunner0519 Posted November 4, 2020 Author Report Share Posted November 4, 2020 (edited) I believe it goes to the brakes. Wow guys thank you for all the help. Curios to how you find these parts so I don't bug you guys. Also, What does this do. Is this an ABS valve or something similar?

Takes the air signal from 1 line to 4 brake pots. Don't worry about bugging people, we're here to help you enjoy your ride, safely. If you were bugging us, there'd only be crickets responding. That valve is available at any truck dealership, a lot of NAPA stores, Amazon, and a handful of online retailers. It's crazy common.

dirtrunner0519 Posted November 4, 2020 Author Report Share Posted November 4, 2020 Found it at a local dist. "Six States Dist." Appreciate the help. Next question, anyone recommend a HDT mechanic or shop in the Salt Lake City, Utah area? Quote Link to comment Share on other sites More sharing options...

beemergary Posted November 16, 2020 Report Share Posted November 16, 2020 Relay valve-Will it come apart? Most things air just need a cleaning and new O-rings. Mud dobbers can plug the exhaust hole and you'll think brakes are sticking. Quote Link to comment Share on other sites More sharing options...
