AIR BAGS
As a vehicle is loaded, the steel suspension springs are pushed down. Your vehicle’s suspension system is
designed to give optimum performance and handling at one specific weight. Often, with an RV or truck
you lose some of the performance when the unit is too heavily loaded. As the springs deflect, the ride may
become “mushy” and you may encounter sway and handling problems. Air helper springs become an active
part of the suspension as weight is added to the vehicle. The more air pressure in your air springs, the more
weight they support. Air helper springs utilize this principle to keep your vehicle level and aid in reducing
the sway and handling problems found in a heavily loaded vehicle.
Rear:
✔
Minimum operating pressure: 20 p.s.i.
Maximum operating pressure: 100 p.s.i.
Recommended range: 60-80 p.s.i. depending on load.
✔
Check inflation pressure weekly. Air bags will normally lose 3-4 p.s.i. per week. A higher rate
indicates leakage. Allow 1 p.s.i. of air pressure for every 40 lbs.of weight
(i.e. 50 p.s.i. to support 2000 lbs).
✔
Periodically check bags for any cracking. If cracking is noticed contact your Coachmen dealer for
repair or replacement of the bag if necessary.
CAUTION:
Be sure the wheels are blocked before
crawling underneath the unit to inspect the bags.
Front:
✔
Class A Motorhomes built on the Workhorse chassis have a coil spring / air bag front suspension.
Air bags should be inflated to 80-90 p.s.i. under load.
DO NOT
allow air pressure to fall below
10 p.s.i.
✔
Routinely inspect brackets for loose bolts or damage.
