354 • SECTION 10 --- CHASSIS INFORMATION
NEPTUNE 2004
Listed below are items that can be checked when the motorhome is in for
periodic maintenance.
NOTE: Never attempt to service the air suspension on a
motorhome with the air bags inflated.
•
Inspect
the outside diameter of the air springs. Check for signs of
irregular wear or heat cracking.
•
Inspect
the air lines to make sure contact does not exist between the
air line and the outside diameter of the air springs. Air lines can rub a
hole in an air spring very quickly.
• Check to see that there is sufficient clearance around the complete
circumference of the air spring while at its maximum diameter.
•
Inspect
the outside diameter of piston for buildup of foreign materials.
(On a reversible sleeve style air spring, the piston is the bottom
component of the air spring.)
• The correct ride height should be maintained. All motorhomes with air
springs have a specified ride height established by the manufacturer.
This height should be maintained within ¼ inch. This dimension can
be checked with the motorhome loaded or empty.
• The leveling valves (or height control valves) play a large part in
ensuring that the total air spring system works as required. Clean,
inspect
and replace if necessary.
• Make sure to check shock absorbers for leaking hydraulic oil and
worn or broken end connectors. If a broken shock is found, replace it
immediately. The shock absorber will normally limit the rebound of
an air spring and keep it from over extending.
• Check the tightness of all mounting hardware (nuts and bolts). If
loose, tighten. Do not over-tighten.
Cleaning:
The approved cleaning method is to use soap and water, methyl alcohol, ethyl
alcohol and isopropyl alcohol. Unapproved cleaning methods include all organic
solvents, open flames, abrasives and direct pressurized steam cleaning.
