Country Coach Motorcoach Questions



Answers to some Country Coach Questions
….a blast from the past …some information shared years ago by Brian Keys a former CC Product Expert

2002 Magna Problem:
I am experiencing difficulty with the roof a/cs on my 2002 Magna. Fan works fine, but they intermittently refuse to blow cold air. So far, techs have been unable to reproduce the problem, let alone correct it.

Answer:
This symptom is sometimes caused by excessive electrical noise or interference in the low voltage electrical system. The noise defies detection when trying to measure it using regular test equipment such as digital multi-meters. Another symptom you may experience is erratic operation of the Fantastic Fan on late model coaches. The culprit is likely a worn “ballast” in one of your fluorescent ceiling lights. Try operating the roof air conditioner when all the fluorescent lights are turned off. Does it now blow cold air? Keep listening to the faint hum of your roof air conditioner’s compressor as you gradually turn on fluorescent lights throughout the coach. Did the compressor stop as you turned on a particular light? If so, then this light fixture needs to be replaced even if it is visibly working fine. Thin-Line has a superior “RFI” ballast available for most of their light fixtures (805-987-5021), email: thinlitesales@thinlite.com.


Inspire Air System Problem:
When using the air system in my Inspire to put air in my tires I cannot seem to inflate them higher than about 95 PSI. The air pressure gauge on my dash reads 120 PSI. Why?

Answer: The air pressure gauge on your dash reads the air pressure in your primary and secondary brake tanks, not the pressure of the auxiliary system that you are using to inflate your tires. The gauge may indicate 120 PSI, but your auxiliary air system pressure could be anywhere from the compressor’s governor’s “cut in” pressure (about 95 PSI) to its cut-out pressure at 120 PSI, assuming the engine is running. Notice how the cut in pressure of 95 PSI is similar to the pressure boundary that you are having difficulty surpassing when inflating your tires?

There are several pneumatic components between the auxiliary air tank on your coach and the tire inflator including a series of fittings, the air inflator itself, and pressure protection valves that cut off the auxiliary air supply in case of a major leak thus leaving some air pressure for continued operation of the brakes. These combine to restrict the air flow that you have available to inflate your tires so when you have about 95 PSI in your tires, the auxiliary air tank will be at about 120 PSI which is the cut-out pressure for the compressor. The compressor stops pumping air into the system, and does not restart because you are still above the 95 PSI cut in pressure.

To get more pressure in your tires, listen for the whooshing sound from the purge valve as the compressor “unloads”. Force the compressor to cycle again by releasing some air from the inflator after it has been removed from the tire. A brief subdued hiss will indicate that the compressor is once again producing air, at which point you should continue to inflate your tire. You will have to repeat these steps several times to inflate your tires over say 110 PSI, but it is possible. Inflating your tires at a truck stop is a lot easier and quicker!


…..and a couple livability answers by Debbie Hollembaek, former VP of Design at the Country Coach LLC company (now owner of DLH Design)


2004 Model Coach Privacy Drape Question:
How do I clean my 2004 Country Coach privacy drapes and maintain my tie backs?

Answer: 04 model coach privacy drapes are black out fabric and need to be dry cleaned. Older model years than 2004 have washable fabric so it can be machine washed or dry cleaned.  What is NOT recommended is “spot cleaning” as the fabric is flame treated and when spot cleaned, halo marks are left on the fabric. If you machine wash privacy drapes it is important to note you’ll be removing the flame retardant.

If your tie backs “distress,” an alternative fix is a drapery rope tie (available at fabric stores and in ready-made drapes department of major stores).

Cabinetry/Wood Furniture Question:
I bought a 2005 Country Coach and I am wondering why the dining chairs and the end table wood does not match exactly to my cabinetry?

Answer:  The cabinetry was made at the CC Factory in the cabinet shop. Chairs and side tables were hand crafted by a local craftperson. Because the items were made outside the CC plant, they did not match exactly, but do exhibit the same exceptional quality craftsmanship.

Troubleshooting the Country Coach DynoMax Chassis Suspension Air Springs – Part 3

Two other installments of Problems/Possible Causes/Remedies for Air Spring issues published earlier. These handy tips are found withing the User's Guide of the Country Coach Motorcoach. These in particular come from the Affinity C-12 DynoMax chassis User's Guide

Problem: Air Spring Failure Due to Fatigue
Possible Causes: Continual or repeated over extension of the air spring.
Remedy: Inspect the shock absorber mountings and bracket. Reconnect loose parts and replace any defective parts. Check the adjustment of the height control valves according to the Ride Height Adjustment procedures in your Owner's Guide.

Problem: Air Spring fails to fully deflate when all weight is removed.
Possible Causes: Restricted air line between the height control valve and the air spring.
Remedy: Disconnect the eight Control Valve linkage and rotate the actuating lever to the 45 degrees down position. If the air spring remains inflated, check for pinced or blocked lines. Clean or replace blocked lines and replace defective valves. (Again, check the Ride Height Adjustment section in the Owner's Guide.)

Problem: Shock Absorber failures.
Possible Cause: Over extension / compression.
Remedy 1: Check to see if perhaps the shock brackets were reinstalled in the wrong location.
Remedy 2: Is is at the proper ride height? Check the Ride Height Adjustment section of the owner's guide.
Remedy 3: Improper replacement brakes may have been installed.

Problem: Excessive Tire Wear.
Possible Cause: Axles or steering improperly aligned.
Remedy 1: Realign wheels
Remedy 2: Worn Pivot Connection. Install new bushing and bolt.

Problem: Front pivot connection worn prematurely.
Possible Cause: Loose/preloaded pivot connection.
Remedy 1: Pivot connection rod bolt improperly torqued. Inspect bushing sleeve for wear. Replace bushings and bolt. Torque to specified foot pounds at ride height.

For light reading (translation: very instructive reading), I always recommend your Country Coach User's Manual is always the first go to source of info when you're needing to deal with a particular coach issue, be it air springs related or otherwise.

Country Coach did a wonderful job of providing support documents, schematics, manuals etc in the "Black Box" of key information that shipped with every coach that rolled onto First Avenue in Junction City, OR to a dealer location or to a new owner.

Today a new Country Coach--Country Coach Corporation--exists on some of the acreage of the original Country Coach Inc campus. Country Coach Corporation is a full service center, preowned coach dealership, and in the future intends to again build a motorhome with the Country Coach moniker gracing its exterior.
