• Q: How to reassemble the alternator on 2008 Toyota 4Runner?

  A: The alternator reassembly requires starting with the drive end frame placement onto the pulley followed by installation of the rotor to this frame. Use Special Service Tool: 09285-76010 and a press to gradually push in the coil assembly with generator washer attached to the rotor through its 4 bolting points that need to be torqued at 5.8 Nm (59 kgf-cm, 51 in-lbf). Begin by hand-tightening the pulley nut before using a torque wrench and pulley holding tool to tighten the socket with a clockwise force of 39 Nm (400 kgf-cm, 29 ft-lbf). During this procedure make sure the tool stays attached to the pulley shaft. Secure both the adapter to a vise then place the socket inside the adapter before attaching the pulley nut to the adapter. Use the indicated method to turn the pulley holding tool to attain a 111 Nm (1,125 kgf-cm, 81 ft-lbf) torque and remove the generator from the adapter while detaching Special Service Tools: 09820-63011, 09820-06010, and 09820-06021. The generator brush holder assembly requires installation of two screws with 1.8 Nm (18 kgf-cm, 16 in-lbf) torque while keeping the brush holder pins aligned with the rear seal plate holes. Apply the terminal insulator by installing it correctly and fasten the end cover using 3 nuts torqued to 4.6 Nm (47 kgf-cm, 41 in-lbf).
