• Q: How to reassemble the alternator on 2009 Toyota Corolla?

  A: The alternator should be assembled by installing the generator drive end frame bearing using Special Service Tool 09950-60010 and 09951-00470 and 09950-70010 and 09951-07100 with a press. Secure the retainer plate between its tabs and the drive end frame cutouts by installing 4 screws which need a torque of 2.3 Nm (23 kgf-cm or 20 in-lbf). The generator rotor assembly goes next after installing the drive end frame on the clutch pulley. Then apply the generator washer to the rotor. Special Service Tools 09612-70100 and 09612-07240 with a press method allow for gradual installation of the generator coil assembly before tightening four bolts to 5.8 Nm (59 kgf-cm, 51 in-lbf). Position two brushes into the holder followed by a 1.0 mm (0.0394 in.)(pin which should be inserted into the brush holder hole before securing the assembly to the generator coil with 2 screws torqued to 1.8 Nm (18 kgf-cm, 16 in-lbf). Remove the pin afterward and repeat the process for the remaining components. The installation of the terminal insulator should be done correctly on the generator coil. A generator rear end cover should be installed to the generator coil by tightening 3 nuts to 4.6 Nm (47 kgf-cm, 41 in-lbf). Place the generator clutch pulley on the rotor shaft before positioning the Rotor Shaft Holding Tool and Clutch Pulley Wrench (SST: 09820-63021). Clamp the tool in a vise. To accomplish the clockwise torque of 111 Nm (1127 kgf-cm, 82 ft-lbf) (84 Nm (857 kgf-cm, 62 ft-lbf while using the Special Service Tool), employ a torque wrench with a fulcrum length of 318 mm (12.52 in.) that ensures an effective torque when parallel to the wrench. End the operation by taking out the generator assembly from the SST then verify smooth clutch pulley motion while installing a fresh clutch pulley cap.
