By Now you know I am kind of new at this, I have been reading as much as I can on the Air Bag system
I have talked to Jim K and he was also very helpful. I have a Question on the Height Control Valve and Travel Mode.
I rebuilt the Control Values using one of JimK Kits, and that worked great, and has 0 leaks. Best $19 I ever spent .
I having issues with Travel Mode, I was thinking that you guys could shed some lite on the subject.
How do you determine correct height for travel mode? Jimk Said to locate the Oval hole on the frame on the passenger side 2 feet behind the wheels. The height should be 11 11/16. So I found the Oval Hole, but is the 11 11/16 from Ground to Bottom of Frame, or Ground to Bottom of Oval Hole? My Friend Barry said that he measures 31 ½ inches between the wheels from ground to the line that separates the Wheel Well and the Center Shirt. How do you tell what the correct Travel height should be?
So, I might Have two bad Height Control Valve’s. For my example I am going to use the Skirt Measurements.
If I raise the Coach up to 35 inches, (about as far as go at 100 psi) then put it into travel, it will drop to about 32 inches in about 5 min. If I lower it to the frame then put it to travel it will rise to about 29 ½ inches in about 15 min. Is it normal to have a 3 inch of play in the value?
The return air flow rate from the Height Control Valve to the Rotary Height Valve is VERY slow, I would say extremely slow. So maybe I have a blockage in the Valve? The Air Feeding the Height Control Valve (Red Tubes) is good, about the max you would expect from ¼ tube.
