A: The first step to remove an alternator starts with disconnecting the negative battery cable. The first step is to remove the rear engine under cover on the right-hand side and the fan and generator V belt. The first step requires the generator connector to be disconnected followed by nut removal to disconnect terminal B wire harness and lastly the separation of clamps on the wire harness. The generator assembly requires removal of two securing bolts before removing the bolt holding the wire harness clamp bracket.
Q: How to service and repair the alternator on Scion xA?
A: The first step to work on an alternator requires complete disassembly. The generator pulley can be removed using Special Service Tool 09820-63010 (09820-06010, 09820-06020) as you tighten the pulley holding tool's socket clockwise to 39 Nm (400 kgf.cm, 29 ft.lbf) until it secures to the rotor shaft. Attach the pulley nut to the adapter after inserting the socket into the adapter which is securely fixed in a vise. Rotate the pulley holding tool counterclockwise while paying attention to prevent the rotor shaft damage by loosening the pulley nut only up to half a turn. Remove the generator from the adapter and carefully eliminate the socket and pulley holding tool before removing the pulley nut and pulley one after the other. Start by unattaching the rear end cover through the sequential removal of the nut followed by terminal insulator followed by bolt and then three nuts and plate terminal and end cover. The generator brush holder assembly requires removal after you detach the brush holder cover and use two screws to disassemble it before proceeding to remove the generator regulator assembly with its three screws. To replace the generator holder with rectifier dismantle the four screws first while the generator rectifier end frame requires removal of four rubber insulators together with seal plate and four nuts and cord clip by using Special Service Tool 09286-46011 for disassembly of this frame component. The rotor generator washer should be removed first followed by removing the rotor from the drive end frame but make sure the rotor does not drop. First install the generator rotor along with its washer before using a 19 mm socket wrench and press to deliberate pressure insertion of the rectifier end frame through four nut and cord clip assembly where torques apply 4.5 N.m (46 kgf.cm, 40 in.lbf) to nut A and 5.4 N.m (55 kgf.cm, 48 in.lbf) to nut B. Mount the seal plate after placing four rubber insulators properly. The generator holder with rectifier should be installed through four screws while torqueing them to 2.9 N.m (30 kgf.cm, 26 in.lbf). Install the generator regulator assembly by torquing three screws to 2.0 N.m (20 kgf.cm, 18 in.lbf) and install the generator brush holder assembly with two screws torqued to the same value, 2.0 N.m (20 kgf.cm, 18 in.lbf), then install the brush holder cover. Put the rear end cover and plate terminal in position with the bolt along with three nuts and apply 3.9 N.m (40 kgf.cm, 34 in.lbf) torque on the bolt while the nuts need 4.4 N.m (45 kgf.cm, 39 in.lbf) torque. Then install the terminal insulator using a nut that should get tightened to 4.1 N.m (42 kgf.cm, 36 in.lbf). The generator pulley installation began with hand-tightening the pulley nut before applying Special Service Tool 09820-63010 (09820-06010, 09820-06020) for turning the torque wrench to tighten the socket clockwise to 39 Nm (400 kgf.cm, 29 ft.lbf) while the tool remained fixed to the pulley shaft. Position the adapter within a vise and put the socket inside the adapter followed by the pulley nut application. Then tighten the pulley nut with the pulley holding tool through clockwise rotation to achieve 133 Nm (1,356 kgf.cm, 98 ft.lbf). First detach the generator from the adapter after which the socket holding tool should be removed by turning the socket and finally the pulley should be checked for smooth movement.
A: Start the alternator removal process by disconnecting the wire from the car's negative battery terminal then wait for 90 seconds to avoid kicking on the Air Bag pretensioners. Begin by removing the front fender apron seal from its right-hand point through 3 clip and 2 screw extraction. The following step involves taking out the fan and generator V belt. Change the process by detaching the generator connector and removing the terminal cap before removing the generator wire nut. Moving on with the procedure include 2 wire harness clamps before replacing the 2 generator bolts and after that unfasten the wire harness clamp bracket bolt.
