bmulvenna@hotmail.com Posted Wednesday at 09:53 PM Share Posted Wednesday at 09:53 PM All air has been drained and coach is blocked and supported on Jack stands. Does anyone have a picture of where the three orings are located in each hwh 6 pack solenoid? I have removed one solenoid and see 1 oring, but old eyes cant see the other 2. I think I read that access to one might require some disassembly. If so, is there any documentation as to how to do this? Also should a lube be applied to the new orings? Thanks in advance.

vito.a Posted Wednesday at 10:08 PM Share Posted Wednesday at 10:08 PM Mike Canter suggests you use Dupont Viton orings. The internal oring is a -019 size, the large one on the bottom is a -028 and the small one on the bottom is a -015. Then remove the 6-pack valves in both front and rear and rebuild them. Label all wires and air lines. It will help to have a special "pin wrench" tool and cannon plug pliers to get the valves apart. You can rebuild them in place but it's a long reach. Here are some links: Air leak in chassis leveling system Leaking HWH Solenoid: These are from Mike Canter. Hope this helps. Link to comment Share on other sites More sharing options...
Solution Ivan K Posted Wednesday at 10:15 PM Solution Share Posted Wednesday at 10:15 PM These are air seal rings, no chemicals, nothing special. Here is a pic I took back when. And I used hvac sealing oring grease just because I had it handy. 1 Link to comment Share on other sites More sharing options...
