Warnings & Safety Statements

NOTE

The air suspension system is not consid-ered to be user-serviceable.

It is recommended that service and re-pairs be performed by a Monroe Truck Equipment facility or other truck equip-ment repair shop.

WARNING

Danger of electrical shock. High current potential at compressor power connec-tion.

Disconnect the vehicle battery or remove the primary power fuse before removing the compressor enclosure cover.

WARNING

Danger of injury from release of com-pressed air.

The compressed air system normally op-erates at 120 psig. Sudden release of air pressure can cause eye injuries and loss of sight.

Wear eye protection when working on the air system components. Disconnect power from the compressor and release all air pressure before working on the air system.

CAUTION

Possible wiring damage or vehicle fire from improper fusing.

Do not bypass the supplied fuses in the electrical circuits. Do not install fuses with a higher current rating than those supplied.

If a fuse burns out, investigate and repair the cause.

Product Description & Specifications

Product Description The MTE air suspension system replaces the OEM leaf spring suspension with swing arms and air springs (inflatable air bags). An air-spring system provides a smoother ride and is self-leveling during all driving and normal loading conditions. Adjustable-dampening shock absorbers are standard with all suspension kits.

A rear sway bar is standard.

The air suspension system requires an MTE air compressor unit and air reservoir.

Operating Parameters and Specifications

Required operating voltage (air compressor): +11 to 15 VDC

Operating air pressure (compressor shut-off) setpoint: 120 psig, + 5 psig

Operating temperature range: -40 to 130o F

CAUTION

The air suspension system is a load-leveling system designed to maintain a specified ride height.

The specified ride height sets the inflat-able air bags at their mid-point of travel when the suspension is at rest.

Operation of the vehicle with the ride height set too high or too low may per-manently damage the air bags.

Ride Height (Measurement “H” shown at right)

4 x 2 wheel drive 11.125”

4 x 4 wheel drive 12.0”

So-Low 4 x 2 wheel drive 8.625”

Normal Operation

Normal Operation of the Air System

For normal operation, keep the Dump (Kneel) switch off.

Start the vehicle engine. If the air pressure in the system is low, the compressor will start immediately. When the

pressure reaches the normal operating pressure, the compressor will stop automatically.

Normal maximum operating pressure is 120 psig. The compressor will start whenever the pressure drops to about

100 psig.

Whenever the vehicle is running, you will hear the compressor start and stop occasionally. The frequency of com-

pressor cycling depends on the amount of movement at the rear suspension. As the suspension moves, it consumes and releases air pressure to keep the chassis level. The more the suspension moves up and down, the more fre-quently the compressor will have to run.

To lower the rear of the vehicle when connecting a trailer, activate the Dump (Kneel) switch. The suspension will

immediately deflate. When the trailer is connected, shut off the Dump switch and verify that the suspension returns to the normal ride height. Never drive the vehicle with the suspension in the Kneel position.

It is normal for the compressor to start when the Dump function is shut off and the suspension begins to inflate.

Emergency Operation

System Operation During Compressor Failure

If the compressor or other component in the enclosure fails and the compressor will not run, air pressure can still be maintained in the suspension system until repairs can be made. Use a compressed air source and a standard tire valve chuck to add air at the Schrader valve in the end of the air tank.

Do not exceed 120 psig when adding air to the tank manually.

If the vehicle must be operated for an extended period in the failure mode, air will have to be added occasionally to

compensate for losses due to movement of the suspension.

If there is an air leak in the system, manual filling of the tank may not be effective except for moving the vehicle a

short distance.

Do not use the Dump (Kneel) function if the system is operating in the failure mode.

CAUTION

Never drive the vehicle with the air bags deflated. Permanent damage to the air bags may occur.

If the compressor system fails, add air manually to the air tank to allow the vehi-cle to be moved to a repair location.

Repair the cause of the compressor sys-tem failure as soon as possible.

Routine Maintenance

Notes

1. Pull cable attached to drain valve at bottom of tank.

2. If the air tank is equipped with the optional automatic drain valve, the valve should open briefly each time the com-pressor runs.

Task Frequency

Weekly Monthly Annually Other

Blow down moisture in air tank 1, 2 X

Activate Dump (Kneel) function X

Observe/check ride height X

Inspect wiring harnesses & air tubing X

Inspect shock absorbers X Replace at 50,000

miles.

Inspect suspension components and bushings X Initial inspection after

first 1,000 miles.

Inspect condition of air bags X

Tighten suspension component fasteners X

Initial check after first 1,000 miles.

Tighten every 25,000

CAUTION

The vehicle owner is responsible for inspection after first 1,000 miles of operation, periodic inspections, maintenance, and proper use of the system.

Suspension components must be inspected and all fasteners and U-bolts retightened after the first 1,000 miles of operation.

Failure to retighten all suspension fasteners at 1,000 miles may result in damage to suspension compo-nents or the axle.

NOTE

Refer to the Air Compressor Owner’s manual for maintenance information on the air system.
