Connecting air lines to control box
After the hubcap is tightened down, push the rubber grommet on the air line down against the
body of the fitting and tighten the nut. Take the tubing from each spindle end and insert them into
the air line tee fitting over the center of the axle. It may be necessary to trim off excess tubing
going to the center of the axle. Repeat this step on all axles.
Insert end of tubing into tee fitting on rear axle and run tubing to the front axle tee fitting and insert
into front axle tee fitting. Make sure to leave enough airline tubing from rear axle to the front axle
for axles that move Independent of each other to distribute load weight. Use tie-wraps to attach
tubing to stationary areas to keep tubing from dragging or getting hooked on anything while truck
is moving.
On the front axle you will need to insert another tee fitting into the airline to connect the air supply
to outlet side on the control box. All airlines connected to the hubcap from each axle will be
hooked up to the outlet side of the control box mounted under the trailer. See Figure 20, 21 and
22
Recommended to route and tie wrap airlines coming off the axles to existing wiring or tubing going
towards the location where the control box is mounted making sure airlines won’t be rubbing
against any sharp edges that may damage airlines.
Center vent lines should be tied up under trailer where duck bill vent is vertical and where duck bill
won’t risk being under water if trailer is parked in a loading bay that may hold water. Make sure to
tie wrap center vent line to the trailer in an area that isnt a moving component which could risk it
being pulled on. Vent line may be wrapped around axle if needed, just make sure duck bill is
facing vertically and then tie wrap vent line to fitting coming of the axle to hold it in place.
