Dual Tire Installation Procedures

1. On dual-wheel installations, ensure valve stems are clocked 180° from each other. If valve stems are clocked incorrectly, remove lug nuts, re-clock wheels, and reinstall lug nuts. See Figure 1.
   A diagram illustrates dual tire valve stem orientation, showing stems positioned 180 degrees apart on the inside and outside wheels. A note indicates that on wheels with 5-hole cutouts, valve stems may not be exactly 180 degrees apart but should be as close as possible, referencing a second image showing a 5-hole wheel example.
   Torque lug nuts to factory specifications.
2. Remove tire valve cap from drive tire. Ensure tire valve threads are clean and free of any debris. Connect straight hose to inside wheel valve stem. Connect hose with 180° bend union to outside wheel valve stem. Hand-tighten plus an additional 1/2 turn using a 7/16" wrench. See Figure 3.
   An image shows hands connecting hoses to the inside and outside wheel valve stems.
   ! CAUTION: Do not overtighten the hose connections. This could damage the hose seal and cause the tire to deflate. Damage to components can occur.
3. After sensor programming, install valve cap sensors on fittings labeled "I" for inside and "O" for outside on the back side of the bracket. Hand-tighten the cap sensors until they bottom out, and then slightly twist the cap sensors to fully seat them. See Figure 4.
   An image shows hands installing cap sensors onto the Flow-Thru Brackets.
   NOTE: Sensors can be installed on bracket before or after bracket is installed to vehicle.
   ! CAUTION: Do not overtighten the sensor caps. Damage to the sensor cap and threads can occur.
4. Connect hose to bracket using knurled fitting, matching "I" to inside hose and “O” to outside hose. Leave knurled fittings slightly loose. See Figure 5.
   A schematic shows how the CP hoses connect to the bracket, with labels "I" for inside and "O" for outside, and the location of the cap sensor.
   ! CAUTION: The knurled ends on the CP hoses are to be hand-tightened only. Do not use tools to tighten. Damage to the knurled ends can occur.
5. Hold bracket up to wheel end or hubcap to determine what mounting bolts will be used to ensure best fitment. Remove corresponding bolts or studs on wheel end or hubcap. See Figure 6.
   An image shows a hand holding a bracket against a wheel hub to determine mounting bolt locations.
   ! CAUTION: Do not twist or kink the hoses during installation. Hoses should not contact wheel.
6. Mount brackets to wheel ends:
   ! WARNING: Refer to specific vehicle manufacturer torque specifications for drive axle cap nuts and hub cap bolts before installing.
   6a. Drive axles: slide bracket over existing axle cap studs, and install provided Nylock half nuts onto studs, or re-use existing axle cap nuts or bolts. See Figure 7.
   An image shows a bracket being installed onto a wheel end, either on axle studs or hub cap bolts.
   Torque drive axle cap nuts or bolts to manufacturers specifications.
   6b. Trailer axles: align flow-thru bracket and reinstall hub cap bolts through bracket mounting holes and hub cap.
   Torque hub cap bolts to hub cap manufacturer specifications (typically 12-16 ft-lbs.).
   NOTE: Some vehicles may be equipped with chrome or other cosmetic hub cap wheel coverings. These wheel coverings must be removed and discarded to enable Flow-Thru Bracket installation. See Figure 8.
   An image shows a before-and-after comparison of cosmetic wheel coverings being removed.
7. Finish hand-tightening knurled hose fittings into bracket. Verify hose is properly seated into the bulkhead by grabbing the check port and turning it back and forth, left to right. If hose turns freely inside bulkhead, continue to tighten the knurled fitting by hand until resistance is felt and hose stops rotating. See Figure 9.
   An image shows hands hand-tightening a knurled hose fitting into the bracket.
   ! CAUTION: The knurled ends on the hoses are to be hand-tightened only. Do not use tools to tighten. Damage to the knurled ends can occur.
8. Note orientation of the Check Ports on the CP hoses. Check ports should face outward, pointing away from the wheel to enable air check and add air. See Figure 10.
   An image shows a close-up of a bracket with check ports, illustrating the preferred orientation pointing outward, away from the wheel.
   NOTE: Do not to force check ports to face outward if it causes the hose to rub on the wheel.
9. Verify double-seal valve caps are tight on check ports. Depress check port cap and listen for air escaping to verify pressure is getting to hose and sensors.
10. Spray all connection points between valve stem, hose, and sensors with soapy water to ensure no leaks. Tighten hose if necessary. See Figure 11.
    An image shows a hand spraying soapy water on a connection point to check for air leaks.
