What is the correct way to purge moisture from the lines? Run the pump with the line disconnected?

My mechanic used compressed air thru the disconnected lines. Seems to have done the trick.

Good to know. I'm a little concerned, because my water separate is too small for my compressor. It might just replace the old water with new...

Most of the moisture trapped in the Air Dryer (Integrated in the Compressor) And some in the valves block. The compressor can be dismantled and dry the air dryer. The valves block also can be dried, You need special tools and understanding the electrical system to do it. If you have no more air leaks It is enough to dries the compressor in time eventually go dry. (Maybe will need more time to dry the compressor)

Great description and diagram.

Should you have really excessive moisture and feel the need there is a supplier on eBay that sells a compressor rebuild kit with replacement filters and drying media as well as the piston ring, new bolts and the wiring ties called LandyAir out of the UK.

I used a kit from Bagpipping Andy and it worked like a charm and was about $30 cheaper and arrived in a few days (using his North American supplier) vs the 1-2 weeks to get the other kit from Britain.

I was able to get rid of the majority of the moisture by clearing the lines and wiping the compressor bore dry prior to reassembly. Also as the temperature was about -10 degrees I decided to fix the absolute minimum needed to get back on the road.

Great diagram, thanks! I assume, and this is an over simplification, that the valve block works something like an ABS controller? It receives information from the leveler at each corner, and actuates the solenoid to open the line for the corresponding corner?

The valve block contains 5 air valves and pressure gauge. And it receives instructions from the height level control computer. The valves work open\ Close.

MrKid

Thanks for another great diagram! So, in theory, you could disconnect each line, open the valve while the compressor is running, and blow the lines out.

amiram

Yes, You disconnect all hoses And the electric plug. Connect an external air pressure source, Connect an external plug (From e Bay) With DC 7 V You open each valve in turn. The plan of the electrical plug Exists

Thanks for the info!
