Fast air leak to 60 psi, then slow

Just read this and went out to the truck. Drivers side tractor bags are really soft, I think you guys may have hit it. Gonna fill with air and shoot with soapy water later today. Will report back.

 

Yeah I’m just trying to find stuff to do since rates are bad. Haha, been sitting for almost 2 months now.

 

Hey thanks SmallPackage! Very interesting! I have a manual 10-speed Meritor-Rockwell trans where the “Selector switch/slave valve on trans” is leaking. So basically I must flip the Hi—Lo selector on the stick before getting on the road, OR ELSE it won’t allow me to shift into High side for approx 30 seconds (until it fills up with air). Runs fine the rest of the day. Gonna try your test and cutoff air to see if it stops the leak. Big Thanks Buddy!

 

That’s a really good idea using the garden sprayer and removing the leveling valve pin. I noticed a tiny leak on the airtank valve, and another tiny leak on the filter-regulator. Gonna install tomorrow and test.

 

So wanted to report back on what I found. It looks like the pressure relief valve on the top of the tank was damaged barely leaking. After I fixed that, the filter regulator before the splitter slave valve started leaking a lot. Still a tiny leak, but stays above 60 psi for almost 24 hours. Thanks for all the ideas guys!
