r600 Posted January 3, 2011 Share Posted January 3, 2011 hey i have r685rst and want to put an air fitting in so i can pump the air up without running the engine can anyone help,cheers adrian Quote Link to comment Share on other sites More sharing options...
Lmackattack Posted January 3, 2011 Share Posted January 3, 2011 well considering that the air compressor is bolted to the engine. the engine needs to run to make air.?put the fitting on the wet air tank so that as air press drops the gov kicks in and puts the compressor back to work. You will need to run a hose from the wet tank up to the deck plate as its a PITA to get under the truck every time you need to get air. or just use the red trailer hose with a glad hand and hose to a air fitting.push the red park knob in when you want to get air from it Quote Link to comment Share on other sites More sharing options...

leversole Posted January 3, 2011 Share Posted January 3, 2011 hey i have r685rst and want to put an air fitting in so i can pump the air up without running the engine can anyone help,cheers adrianMine and most I have seen use one of the main air tank bungs...just screw in a male air hose quick connect (the same style as your shop air comressor uses) where it is easily accessible and you can use it to fill the tank without the engine running and it doubles as a way to hook up a hose to air up tires etc with the truck air supply...

Lmackattack Posted January 4, 2011 Share Posted January 4, 2011 Oh.... sorry, I miss read what you wanted to do... anyways. find the air tank that the air compressor feeds into. Just follow the copper line from the compressor to the first air tank. thats your "wet tank". Put a air fitting onto that tank and it will feed air to the whole system just as if the truck was running. you will have parking and service air press as soon as you start filling it.Trent Quote Link to comment Share on other sites More sharing options...

MACKS Posted January 4, 2011 Share Posted January 4, 2011 Try to find a spot on the top side of the tank so you don't end up with an oily mess when you hook up your air hose. Quote Link to comment Share on other sites More sharing options...
r600 Posted January 9, 2011 Author Share Posted January 9, 2011 is this the wet tank or is it one of the ones inside the chassis????? Quote Link to comment Share on other sites More sharing options...
Rob Posted January 9, 2011 Share Posted January 9, 2011 is this the wet tank or is it one of the ones inside the chassis?????Really hard to tell from any photo. If you follow the copper line from the discharge port of the compressor, (usually 3/4" copper) to the first tank it comes to, that will be your wet tank.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

RowdyRebel Posted January 9, 2011 Share Posted January 9, 2011 Mine and most I have seen use one of the main air tank bungs...just screw in a male air hose quick connect (the same style as your shop air comressor uses) where it is easily accessible and you can use it to fill the tank without the engine running and it doubles as a way to hook up a hose to air up tires etc with the truck air supply...Don't you mean a female quick-connect? The male ends do not restrict airflow when uncoupled, so it would drain the air tank the moment the shop air was disconnected.On my truck, there are two tanks in front of the passenger side fuel tank. The top one is the one that has the most oil/water to drain if/when necessary...so that's the one I put a female quick-connect on.Then, I took 2 male ends and a simple valve in between and use that adapter to hook up to shop air (or to service truck air if necessary). I carry various male ends in my tool box, because it seems like you can go to 3 or 4 different shops and find 'em using 3 or 4 different styles of quick-connects....easy enough to swap out for the one you need on your adapter IF you have it.
