• 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 it 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. See Figure 23-
SmartSense for SmartSense installation.
• 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 so that duck bill vent is vertical and so that 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 isn’t 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.
