ADJUSTABLE ANGLE TPMS SENSOR MANUAL MOUNTING GUIDELINES Hyundai/Kia design 1 Date : 06 March 30 th TPMS SENSOR SERVICE GUIDELINES ADJUSTABLE ANGLE TPMS SENSOR MANUAL MOUNTING GUIDELINES Hyundai/Kia design 2 Date : 06 March 30 th TPMS SENSOR SERVICE GUIDELINES SCOPE AND SUMMARY: This document outlines the guidelines for the manual mounting on the rim of EnTire/TRW adjustable angle TPM sensors. This document does not cover any other TPM sensors. -Sensor & valve components – Step 1 Insert and check screw – Step 2 Assemble valve and sensor – Step 3 Start fitting the valve unit on the rim – Step 4 Break the flange inside the nut – Step 5 Tighten the nut – Step 6 Check the assembly sensor  valve  rim 3 Date : 06 March 30 th TPMS SENSOR SERVICE GUIDELINES Sensor & valve components Screw Pressure sensor Valve stem Rubber grommet nut Plastic washer Valve cap Break away flangeinside the nut 4 Date : 06 March 30 th TPMS SENSOR SERVICE GUIDELINES Step 1 : Insert and check screw The square part of the screw is designed to fit into the slot of the sensor housing. Installed in the slot, the screw will not be allowed to turn making the use of a tool unnecessary. Insert the screw into the slotted hole of the sensor. Check that the flats of the square on the screw fit inside the edges of the hole. Not properly fitted Fitted in the slot YES NO 5 Date : 06 March 30 th TPMS SENSOR SERVICE GUIDELINES Step 2 : Assemble valve and sensor The sensor housing has a hemispherical metallic insert while the valve stem presents a corresponding hemispherical shaped head. This will make the valve stem fit precisely and smoothly into the sensor at an adjustable angle. Sensor housing Valve stem head While holding the screw in the slotted hole with a finger, assemble the valve to the screw, and turn the valve 3 to 4 full rotations. Check that the square part of the screw is well seated in the sensor’s slotted hole. Check that the valve stem is still loose.It must be free to move up and down the full length of the slot as shown in this drawing. 6 Date : 06 March 30 th TPMS SENSOR SERVICE GUIDELINES On this cross section of the nut we can see a flange. The role of this break away flange is to tighten the valve on the sensor. Step 3 : Start fitting the valve unit on the rim Drop center Sealing surface Slide the loosely assembled valve unit through the valve hole of the rim. Hold the sensor’s feet against the rim and the rubber grommet against the sealing surface. Insert the nut over the valve stem. Start tightening the nut using a deep 11 mm socket. More about the nut : The tightening of the nut will bring the break-away flange in contact with the valve stem’s shoulder. Turning the nut will now turn the valve stem too. Sensor foot 7 Date : 06 March 30 th TPMS SENSOR SERVICE GUIDELINES Step 4 : Break the flange inside the nut ! At this point the attachment of the valve stem to the sensor is finished and configured to the rim.Proceed to step 5 to tighten the nut. The head of the screw will soon have tight contact with the sensor housing. Note : Speed tightening must be > 15RPM to break the flange properly. (Each quarter turn must take less than one second) Continue to tighten the nut using the torque wrench until the thin flange breaks at approximately 2.2 Nm (20 lbf.in). The operator will feel an initial resistance before the break. 8 Date : 06 March 30 th TPMS SENSOR SERVICE GUIDELINES Step 5 : Tighten the nut Continue to tighten the nut until the recommended 4.0 Nm (35 lbf.in) is reached. A recommended 4.0 Nm (35 lbf.in) torque setting allows the final torque to be between 3.5 to 4.5 Nm (30 to 40 lbf.in) if a +/- 12 % tolerance torque wrench is used. Note: it is recommended to use a class B tool or a class C tool. Below, the standard recommended torque range is given by the ETRTO, TRA for a rubber corner joint valve. Important :Tighten slowly with quarter turn steps until the final torque is reached. Dispersion with +/- 12% tolerance (example)Standards recommended rangeOut of range 4.5 3.5 4.0 5.0 3.0 (Nm) 0 Nut manual tightening Torque 40 30 35 45 25 (lbf.in) 0 9 Date : 06 March 30 th TPMS SENSOR SERVICE GUIDELINES Step 6 : Check the assembly sensor- valve- rim Check that the valve is firmly attached to the rim and that the sensor is firmly attached to the valve. Final positioning of the sensor feet is dependent on the wheel dimensions and may not be uniform.Possibilities are neither foot, one foot or both feet may contact the wheel drop center. WARNING : Risk of damage during the tire mounting / dismounting if the sensor is not firmly attached to the valve.
