Chester,

The numbers you referenced are for king of the road valves. You only have three, one in front and two in back.   Call me if this doesn't make sense to you. 817 223 2056

Rob at Dayton Air Controls told us that you may have a detailed procedure on how to change these valves out. We received the new valves and realized that they are a different style. We hope to have you help us to figure out the best way to adapt them to what we currently have. Please e-mail us back or call at 605-484-9122. Thanks Rick and Cindy Freeman

I don't know if you would call it a detailed procedure.

If you ordered the valves from Rob he would have directed you to the ones made to replace the Ridewell valves. The reason this is important is the Ridewell mounting holes are horizontal and the KOR holes are vertical. Or vice versa. Anyhoo, if you bought the Ridewell replacements, the holes will mount up with the existing holes. If you can get the rear tires off, this will be much easier. If not, it can be done but the installer needs to be sort of little like me.

There are two bolts that hold the valve to the frame rail. The valves should have come to you with push on air fittings. The only thing to be careful of is to keep the supply line from coach air, and the line going to the six pack going to the right port on the valve.

Keep in mind you will need to exhaust all the supply air to make the change. In theory, and in practice the six pack should keep the air bags inflated and the coach up. However, it would be insane to do this work with out blocking the frame of the coach to keep it from crushing the installer.

Adjust the linkage to obtain the correct ride height. You can do this much easier, if you will let the coach down to below ride height and then put in travel mode before taking a measurement. If you let it settle from above ride height the hysteresis in the valve can trick you.

If this doesn't compute with you call me at 817 223 2056

Ok we have our new drive axle air bags replaced and have replaced the two rear HCVs. We tried lifting the coach with the raise button on the control panel and the rear air bags appear to get some air in them but they are not lifting to the normal 2 to 3 inches above the drive wheels. We are not sure what could be hooked up wrong but any direction on what to check next would be great. If the air lines were put on the HCV valves incorrectly would that cause this type of problem? The blue Ridewell valves didn't have any writing on them what each port was. We put the air line that had a constant supply of air when we disconnected it from the Ridewell valve on to the port next to the black exhaust tubing and we put the other air line that had no air pressure when disconnected on the Air Spring Port. Is this correct?? Thanks for any help.

Any HWH control panel setting other than "Travel" should isolate the HCV's from the air bags. Those setting will isolate the air bags from all inputs unless "Raise", "lower" or one of the "up" or Down buttons is being actively pushed.

If you can get the rear raised at all, does it stay up? If not, then (when the control panel light "Travel" is off) if the rear drops you most likely have air leaks related to the bag installation.

When we have the HWH button for raise we have no air going to the new air drive bags we just installed. When it is on raise mode does it get the air through the HCV or directly from the 6 pack??
How does the 1/4 inch air line from the air supply tank get routed into the large air line that goes into the air bag?

Ok we think we have it fixed now. The HCVs were installed upside down. 1st issue. Then the pass side lifted but the drivers side not but was able locate an air leak on that side. Hopefully should work now. Thanks to everyone that helped us!!
