CHASSIS INFORMATION
DIPLOMAT 2004
Air ride springs are available in single, double and triple convolution types plus
reversible sleeve models for virtually every conceivable heavy-duty vehicle
suspension application.
1. STUD:
Manufactured as a permanent part of bead plate
assembly for maximum strength and durability. Used to attach
spring to the vehicle's suspension.
2. BEAD PLATE:
Crimped onto bellows at the factory for a
durable design and maximum quality control. Allows 100% leak
proof testing prior to shipment.
3. BELLOWS:
"Air bag" includes four plies of material: an inner
layer, two plies of cord-reinforced fabric and an outer cover.
Natural rubber construction provides functional properties up to -
65º F.
4. BUMPERS:
A solid rubber or engineered plastic device designed
to prevent significant damage to the vehicle or its suspension in
event of a sudden loss of air pressure in spring.
5. PISTON:
Provides a lower mounting arrangement for air spring.
Controls characteristics of spring under changing pressure loads.
6. PISTON BOLT:
Attaches piston to bellows. Sometimes
extended as a means of attaching spring to vehicle suspension.
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 O.D. 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 O.D. 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 O.D. 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 in. This
dimension can be checked with the vehicle loaded or empty.
