• Q: How to service and repair the alternator on 2000 Toyota Echo?

  A: Disassembly of the alternator starts with the removal of rear end cover components which include the nut and terminal insulator followed by the bolt and three nuts and plate terminal and end cover. Start by taking off the seal plate from the rectifier end frame after removing the brush holder and voltage regulator through a process which includes the brush holder cover followed by 5 screws and brush holder and voltage regulator. The rectifier holder requires disassembly through removal of 4 screws and holder and then 4 rubber insulators. Use Special Service Tool 09820-63010 while holding the tool with a torque wrench to tighten its socket clockwise until it reaches 39 Nm (400 kgf.cm, 29 ft.lbf) while making sure the tool remains secured to the rotor shaft. Place the adapter into a mounted vise while sliding in the socket and attaching the pulley nut and carefully loosen the nut in the counterclockwise direction just over half a turn to prevent rotor shaft damage. Conclude the generator adapter procedure by detaching the socket and pulley holding tool through socket rotation and discarding the pulley nut and pulley. First remove the four nuts while you unfasten the wire clip on the rectifier end frame then employ Special Service Tool 09286 - 46011 to detach the frame before taking out the generator washer from the rotor. The first step for reassembly requires the placement of the rectifier end frame onto the pulley before installing the rotor onto the drive end frame. Use the 29 mm socket wrench and press to install the rectifier end frame cautiously until it reaches proper torque values where Nut A requires 4.5 Nm (46 kg.cm, 40 in.lb) and Nut B needs 5.4 Nm (55 kg.cm, 48 in.lb). Apply hand power to the nut before using the pulley holding tool with a torque wrench to turn the socket clockwise to 39 N.m (400 kg.cm, 29 ft.lb) while maintaining secure attachment to the pulley shaft. First secure the adapter in a vise after inserting the socket then fasten the pulley nut but do it in a clockwise direction to 111 N.m (1,132 kg.cm, 82 ft.lb). Finally remove the generator from the adapter when completed. Secure the rectifier holder by placing rubber insulators onto the wires then fitting it by screwing 4 times with 2.9Nm (30kg.cm, 26in.lb) torque. First place the seal plate on the rectifier end frame before positioning the voltage regulator and brush holder in the correct orientation and installing 5 screws with 2.0 Nm (20 kg.cm, 18 in.lb) torque followed by applying the brush holder cover on the holder. You will finish the installation by attaching the end cover and plate terminal using the bolt and 3 nuts while tightening Nut 4.4 Nm (45 kg.cm, 39 in.lb) and Bolt 3.9 Nm (39 kg.cm, 35 in.lb). Afterward, install the terminal insulator by tightening the nut to 4.1 Nm (42 kg.cm, 36 in.lb). Test the rotor for normal movement without any obstruction.
