• Q: How to service and repair an alternator on 2000 Toyota Corolla?

  A: The disassembly process starts with removing the rear end cover by unfastening its terminal insulator and tightening the nut and bolt before proceeding to unlink the three nuts and plate terminal and end cover. The brush holder along with the voltage regulator can be detached through the removal of the brush holder cover and 5 screws. Unscrew the four screws of the rectifier holder before extracting it together with the four rubber insulators and seal plate. When working with the pulley use Special Service Tool: 09820-63010 through a torque wrench to hold the tool with a socket that needs tightening clockwise to 39 Nm (400 kg.cm, 29 ft.lb) while keeping it secure to the rotor shaft. Set the pulley nut in the vise adapter while inserting the socket then attach it before loosening counterclockwise only up to half a turn to protect the rotor shaft from damage. Begin by eliminating the generator from the adapter followed by removal of the socket and pulley holding tool and finally taking out the pulley nut and pulley. The next step involves disconnecting the rectifier end frame through 4 nut and cord clip removal while using Special Service Tool 09286-46011 to detach the frame and extract the generator washer. The procedure for replacing the front bearing requires you to begin by removing 4 screws as well as the bearing retainer and bearing. Then press out the bearing with a socket wrench and press before installing a new bearing using Special Service Tool 09950-60010 (09951-00500) and securing the bearing retainer with 4 screws at 3.0 Nm (31 kg.cm, 27 in.lb). You can replace rear bearing components using Special Service Tool 09820-00021 to disconnect the outer bearing cover and bearing with fan protection in mind before taking out the inner cover for rotor installation followed by bearing insertion with Special Service Tool 09820-00030. Fitting the outer bearing cover requires Special Service Tool 09285-76010 for proper insertion. The procedure for reassembly requires attachment of the rotor to the drive end frame by first positioning the rectifier end frame on the pulley and then setting the rotor onto the frame. Follow this step by installing the generator washer onto the rotor before tightening the rectifier end frame using a 29 mm socket wrench while securing the cord clip with 4 Nut A at 4.5 Nm (46 kg.cm, 40 in.lb) and 4 Nut B at 5.4 Nm (55 kg.cm, 48 in.lb). Complete the installation by hand-tightening the pulley nut before using the pulley holding tool with a torque wrench to achieve 39 N.m (400 kgf.cm, 29 ft.lbf) clockwise torque to the pulley shaft. Inspect the tool's The generator removal from the adapter requires a pulley nut torque of 133 N.m (1,356 kgf.cm, 98 ft.lbf). Secure the rectifier holder by setting the seal plate onto the rectifier end frame before adding the 4 rubber insulators to the lead wires and torquing the holder screws to 2.9 Nm (30 kg.cm, 26 in.lb). Install the voltage regulator together with the brush holder on the rectifier end frame while orienting them correctly and fasten with 2.0 Nm (20 kg.cm, 18 in.lb) prior to adding the brush holder cover. The installation procedure concludes with 3 nut screws 3.9 Nm (39 kg.cm, 35 in.lb) and one screw 3.9 Nm (39 kg.cm, 35 in.lb) along with the 4.4 Nm (45 kg.cm, 39 in.lb) fastening of the nut. Then the terminal insulator is added with the nut at 4.1 Nm (42 kg.cm, 36 in.lb) and a rotor smooth rotation must be checked afterward.
