• Q: How to reassemble the alternator on 2008 Toyota Corolla?

  A: The alternator reassembly process starts with positioning the generator drive end frame on the generator pulley before setting the generator rotor onto the frame followed by the generator washer installation. The installation process requires a 29 mm socket wrench and a press to gradually insert the generator rectifier end frame before adding the generator cord clip and 4 nuts which must achieve 4.5 Nm (46 kgf-cm, 40 in-lbf) torque for Nut A while Nut B needs 5.4 Nm (55 kgf-cm, 48 in-lbf). Fasten 4 terminal insulators to the rectifier end frame before attaching the generator holder with rectifier by torquing 4 screws to 2.9 Nm (30 kgf-cm, 26 in-lbf). After securing the 3 generator regulator assembly screws to 2.0 Nm (20 kgf-cm, 18 in-lbf), position the generator brush holder properly before attaching the generator plate seal and brush cover with rear end cover fastened with 2 nuts torqued to 4.4 Nm (45 kgf-cm, 39 in-lbf). The terminal plate installation requires a bolt with 3.9 Nm (40 kgf-cm, 35 in-lbf) torque along with 4.4 Nm (45 kgf-cm, 39 in-lbf) torque on the nut before adding the terminal insulator secured with a 4.1 Nm (42 kgf-cm, 36 in-lbf) torque. Use the combination of Special Service Tools 09820-63010, 09820-06010 and 09820-06020 to fasten the pulley nut securely while holding Special Service Tool1-A so that the torque wrench can tighten Special Service Tool1-B counterclockwise until it reaches 39 Nm (400 kgf-cm, 29 ft-lbf). Place Special Service Tool2 into a vise then attach Special Service Tool1-A and B to it by adding the pulley nut followed by slowly tight the tool using the indicated direction to 133 Nm (1351 kgf-cm, 97 ft-lbf). Complete this process by taking off the generator from Special Service Tool2 then turning Special Service Tool1-B while removing Special Service Tool1-A and B making certain the generator pulley operates effortlessly.
