f438921 Report post Posted August 26, 2018 My front air suspension will drop right down overnight, so I lifted it up as high as it will go and then sprayed down the airbags, lines, fittings and I found the solenoid 6 pack bubbling from between the solenoid and the base it mounts to. I ordered the o-ring seal kit for it and will be replacing them as soon as the parts arrive and I need to know if anyone here has had the same problem and is there any tips, tricks or problems you have ran into while changing them? I plan on lifting it as high as it goes, put the safety stands under it and lower it down onto them and drain all the air out of the system and take it apart. I have included a short video of the leak as well. IMG_7181.m4v Share this post Link to post Share on other sites
hermanmullins Report post Posted August 26, 2018 Grant That was a good video of the leak. Let us know how it turns out. While waiting on the seal kit to arrive, you might give the whole assembly a good spraying of WD-40 to clean the valve bodies.If your Monaco is like mine the assembly is wide open to every bit of dirt that can be thrown at it. Good luck, Herman Share this post Link to post Share on other sites
wolfe10 Report post Posted August 26, 2018 Either label each air line and wire or "service them" one at a time so all connections remain where they should. Share this post Link to post Share on other sites

Good luck, Herman Herman are you saying to spray the entire outside of it down before taking it apart to clean it? Share this post Link to post Share on other sites
hermanmullins Report post Posted August 26, 2018 Yes WD 40 is a pretty good cleaner. However it may take a lot. When I was building elevators we kept it in 5 gallon cans to clean equipment with. I would suggest a dropcloth under it. Herman Share this post Link to post Share on other sites
dickandlois Report post Posted August 27, 2018 F438921, I use a degreaser - if you keep Simple Green Extreme in stock to clean your radiator and CAC, that will work very well to clean off the dirt and grime. Then rinse things off with water. Much less expensive then WD-40. The air manifolds are usually not that bad to get to and with all the air discharged. I do not think you will need to use jack stands? Bretts, thought on doing one at a time makes it hard to mix up the connection sequence. Other wise label the lines and take some good pictures. Much easier to keep the lines in there proper location.. When installing, use plane vegetable oil to make installing the new "O" rings - it will not harm them. Rich.

Well if I don't use jack stands to hold the Coach up then how would you get under it? Share this post Link to post Share on other sites
dickandlois Report post Posted August 27, 2018 I'm Slender enough to slide under the coach if needed. My air control valves are in locations that are not to bad to get to once I'm under the coach. If I need a little more room - using some 2 x 12 by 18 to 24 in. blocks to park on can make a big difference. Jack stands that will hold up under the weight of the coach are bulky and heavy. Wood parking blocks pack better and are much lighter. The hydraulic leveling pump and manifold are in one of the rear bays and one can work on them setting down on a stool. I did replace 2 hydraulic lines in Alaska using just blocks and a good sized piece of cardboard to slide on. Took a few hrs., but the labor rate was good ! Rich.

kaypsmith Report post Posted August 27, 2018 Wow, I haven't been that thin since 5th grade in school. Currently 52 suit coat size, and 38 waist, so I still can't make, this coach after air bags settling, no air leaks is only 6 inches off the ground. Share this post Link to post Share on other sites

spooky Report post Posted May 27, 2022 Hi! I have a 2001 Monaco dynasty 40 foot and I cut six-by-six and wedged them. I can drive up on them and work on everything with no air in the system. Share this post Link to post Share on other sites
