Scion xB Parts Questions & Answers

• Tire Pressure Sensor, Driver Side
  84746-AE010
  Q: How should the TPMS Sensor and transmitter be disposed of correctly on Scion xB?

  A: Correct disposal of the tire pressure warning valve and transmitter requires a lithium battery. Begin the disposal process for the tire pressure warning valve and transmitter by separating the back cover with a screwdriver tip until you reveal its battery along with the base board resin layer. During battery removal you need to cut the two terminals that join the base board.

  Q: How to install the No. 2 back door name plate and symbol emblem on Scion xB?

  A: The first step to install the No. 2 back door name plate requires using an infrared light to heat the double-sided adhesive tape on the back door panel until it reaches 40 to 60 degrees Celsius (104 to 140 degrees Fahrenheit) for 1 to 2 minutes followed by immediate removal of the tape with a shop rag before cleaning the surface. The installation process of No.2 back door name plates requires total removal of double-sided tape followed by cleaning the surface with a non-residue solvent. The installation environment for the new No. 2 back door name plate must maintain temperatures above 20 degrees Celsius (68 degrees Fahrenheit) but the installation should be delayed if the temperature falls below this threshold since back door panel and name plate heating to 20 to 30 degrees Celsius (68 to 86 degrees Fahrenheit) temperatures is required. When installing the symbol emblem duplicate the cleaning protocol by warming the last bits of double-sided adhesive tape on the back door panel and removing it during its hot stage while cleaning the surface with a non-residue solvent. Place the 2 bosses onto the back door panel to install the symbol emblem under conditions where ambient temperature stays above 20 degrees Celsius (68 degrees Fahrenheit) or warm up both elements to 20 to 30 degrees Celsius (68 to 86 degrees Fahrenheit).
• Alternator

  Q: How to overhaul the alternator assembly on Scion xB?

  A: Begin generator assembly overhaul by using Special Service Tool 09820-63010 (or its alternatives 09820-06010 and 09820-06020) to remove the pulley by attaching the tool to the rotor shaft so it can reach a torque force of 39 Nm (400 kgf.cm, 29 ft.lbf). Tighten the pulley nut counterclockwise for less than half a turn until you detach the generator from the adapter before pulling out the pulley nut and pulley. The procedure begins by disconnecting the rear end cover through the removal sequence of nut and terminal insulator and then bolt and plate terminal and three nuts. Start the procedure by taking off the generator brush holder cover then unscrewing its two screws before removing the three screws holding the regulator in place. Special Service Tool 09286-46011 helps users remove the generator rectifier end frame by first unfastening the four screws holding the generator holder with rectifier then taking away its four rubber insulators, seal plate and four nuts, and clip code. You must first detach the generator washer before extracting the rotor out of the drive end frame accurately. Terminal F to B and F to E should show a specific level of continuity in the regulator assembly so you should replace the regulator in case this condition is not met. Open circuits and grounds of the generator rotor assembly should be checked while verifying the slip rings have correct continuity and ensuring the slip rings do not touch the rotor. Replace the rotor as needed. Use vernier calipers to measure the slip ring diameter which must stay within standard limits while checking the bearing condition for wear. Examine both the positive and negative rectifiers of the generator holder with rectifier for continuity until you need to replace the rectifier holder when the continuity is not as specified. The stator coil should be inspected for open circuits along with grounds while missing continuity points to the generator assembly for replacement and a bearing wear check must be performed. Rephrase the brush holder assembly replacement rule when the exposed brush length falls under the minimum acceptable standard. The installation of the generator rotor assembly requires putting the rotor along with the washer in their original positions. The 19 mm socket wrench allows users to press in the end frame of the generator rectifier before securing it with four nuts and clip code at specified torque values. Then users install seal plate and rubber insulators. Connect the generator holder with its rectifier parts by installing four screws at the appropriate torque levels and then connect generator regulator parts by installing three screws followed by the generator brush holder assembly connection with two screws while maintaining correct installation orientation. The final step includes attaching the rear end cover through bolt and three nut torque specifications before securing the terminal insulator with a nut and installing a generator pulley by hand. After this apply the pulley nut torque settings with a holding tool to 39 Nm (400 kgf.cm, 29 ft.lbf) then continue to 111 Nm (1,125 kgf.cm, 81 ft.lbf) to get smooth pulley movement.
• Exhaust Manifold

  Q: How to install the Catalytic Converter sub-assembly on Scion xB?

  A: Install the No. 2 exhaust manifold heat insulator first using 2 bolts that should attain 12 Nm (122 kgf-cm, 9 ft-lbf) of torque. After mounding the 4 bolts of the No. 1 manifold converter insulator it should be torqued to 12 Nm (122 kgf-cm, 9 ft-lbf). The exhaust manifold installation requires the use of new gaskets for nuts which must be tightened in the given sequence with a torquing value of 37 Nm (377 kgf-cm, 27 ft-lbf). After bolting the manifold stay using a nut and torquing it to 44 Nm (449 kgf-cm, 33 ft-lbf) you must install the No. 2 manifold stay using the same bolt and nut procedure and torquing force of 44 Nm (449 kgf-cm, 33 ft-lbf). Mount the front exhaust pipe by applying 4 bolts and installing two required compression springs. The procedure begins with sensor installation for the air fuel ratio followed by application of the No. 1 exhaust manifold insulator followed by exhaust gas leak inspection before the No. 1 engine under cover installation.
