The tag axle is optional equipment on all motorhomes which
are 40 foot. The tag axle design allows for more carry weight,
thus making it possible to create a wider variety and range of
floor plans.
While the tire should be off the ground there is no specific
height requirement for the tag axle in the up position. If the tag
axle requires being raised higher, adjustments can be made by
taking up one chain link on the tag axle.
The tag axle switch is located on the left hand shifter panel.
There are two lights on this switch: One to be lit when the
headlights are turned to the on position. The other to be lit
when the tag axle switch is turned on. The tag axle should only
be in the raised position when severe maneuvering in your
motorhome is performed under 5 mph.
If the tag axle switch is in the raised position while you start your coach a
beeping alarm will sound. You will need to flip the switch to lower the tag
axle. Once the tag is lowered it will require a few minutes with the engine
running to build up enough air pressure before it will be ready to travel.
When a tag axle switch is turned on in a motorhome with air leveling the
following will take place: The 12 Volt power will be in the 14 gauge yellow
with green stripe wire, which will go all the way to the rear mac valve for
the tag axle located on the roadside rear. Once the rear mac valve has been
activated the air pressure will go through the orange air line to both tag axle
brake chambers to lift the tag. The air in the air bags will be released to the
outside air. The tag axle will remain in the raised position until the switch is
turned to the off position.
The amount of weight carried by the tag axle may be adjusted by chang-
ing the amount of downward force applied to the tag axle. Changing the
amount of weight carried by the tag axle affects how the weight is distrib-
uted between the tag, drive and steering axles. The amount of down force
applied to the tag axle is controlled by the amount of air pressure in the tag
axle air bags. The amount of air pressure in the tag axle air bags is set by an
adjustable pressure regulator located in the engine compartment. The tag
axle regulator pressure is preset at the factory and may require adjustment to
obtain the proper weight distribution on all axles. To determine the correct
setting of the pressure regulator the motorhome will need weighed after it
has been loaded for travel.
All tag axles will use the oil bath hubs on the tag axle only. The tag axle
has a chrome hub cap that will need to be removed before the inspection can
take place. You can locate the full and add mark on the outside of the plastic
see-through cover. You will be able to see the oil level. You should inspect
the oil level before every trip or every 5,000 miles.
