mcratchet1 Posted May 4, 2020 Share Posted May 4, 2020 2006 mr688s just replaced d2 because not building air on idle at startup its constantly leaking air out of ehaust port. So i have to idle up to build air but once air is built up it stops also getting alot of water in tanks at the end of the day. Is this signs of air compressor failing i replaced it 2 years ago with bendix reman Any insight i would be grateful!! Quote Link to comment Share on other sites More sharing options...
j hancock Posted May 6, 2020 Share Posted May 6, 2020 Compressor could be failing. Just water or some coolant when it is drained? Are you running an air dryer? Quote JimIt doesn't cost anything to pay attention. Link to comment Share on other sites More sharing options...

j hancock Posted May 7, 2020 Share Posted May 7, 2020 FLA is a little humid so that isn't helping with the water. Sort of surprised that the purge on the dryer isn't keeping up. Could inspect the air inlet to the compressor and the discharge for any damage, kink or restrictions to help with slow air build. If there is carbon buildup in the discharge line, the line should be replaced. 1 Quote JimIt doesn't cost anything to pay attention. Link to comment Share on other sites More sharing options...

Joey Mack Posted May 21, 2020 Share Posted May 21, 2020 If you have ruled out air leaks and excessive usage. try bypassing the air dryer by hooking the 2 big lines together, then checking operation. it pressure goes up correctly, repair the air dryer. just a thougt..

Mack Technician Posted May 24, 2020 Share Posted May 24, 2020 Got a bad D2 from Mack not long ago, out of the box. Wuda pain. You need to gauge the system and figure out if the Governor is lying or if you have a leak somewhere. You don’t know what the Governor is sensing coming from the wet tank because you have no normal gauge there, it’s isolated from primary and secondary by check valves. Wet tank is the third unmonitored tank your Governor uses. It a septum tank usually. Quote Link to comment Share on other sites More sharing options...
