2004 Toyota Land Cruiser Alternator Parts Q&A

• Q: How to service and repair the alternator on 2004 Toyota Land Cruiser?

  A: The alternator disassembly process begins by removing 3 screws then the rear end cover before taking off the 3 nuts with end cover before finally detached terminal insulator. You should start by removing the rear seal plate from the brush holder after which you detach the 2 screws and brush holder followed by removal of the front seal plate from the coil assembly. Secure the tool by tightening the socket which uses Special Service Tool 09820-63010 with a torque wrench to 39 Nm (400 kgf.cm, 29 ft.lbf) on the rotor shaft. When mounting the adapter into a vise position and inserting the socket fixture and pulley nut aligns with the adapter you can twist the tool counterclockwise but avoid turning more than a half revolution to protect the rotor shaft. Detach the generator from the adapter while manipulating the socket to discard both tool and socket before uninstalling the pulley nut and pulley. Use Special Service Tool 09950-40011 (with renaming parts as 09951-04020, 09952-04010, 09953-04020, 09954-04010, 09955-04071, 09958-04011) to remove the 4 bolts to extract the coil assembly followed by removing the generator washer. The procedure for changing the front bearing begins by removing four screws and both the bearing retainer and bearing and completing the bearing removal with Special Service Tools 09950-60010 (09951-00250) and 09950-70010 (09951-07100). Place the new bearing inside the pressing machine using required tools before installing the bearing retainer using 4 screws at 2.6 N.m torque settings (27 kgf.cm, 23 in.lbf). Succeeding the bearing cover removal with Special Service Tool 09820-00021 (protecting the fan from damage), the technician will push in a new bearing using Special Service Tool 09820-00031 before using Special Service Tool 09285-76010 to correctly insert the bearing cover. Reassembly starts by installing the rotor to the drive end frame but first putting the generator washer on it before using Special Service Tool 09285-76010 to insert the coil assembly then securing it with 4 bolts at 5.8 N.m (59 kgf.cm, 51 in.lbf). The installer should use the pulley holding tool (Special Service Tool 09820-63011) for attaching the pulley to the rotor shaft before applying 39 Nm (400 kgf.cm, 29 ft.lbf) torque onto the pulley nut then final torqueing at 110.3 Nm (1,125 kgf-cm, 81 ft-lbf). The installation of the front seal plate on the coil assembly requires proper alignment of the pins with the rear seal plate before you attach it. Install 2 screws to secure the brush holder at 1.8 N.m (18 kgf.cm, 16 in.lbf). After installing the terminal insulator you need to apply end cover nuts using 4.6 N.m (47 kgf.cm, 41 in.lbf) before adding the rear end cover with 3 screws also tightened to this torque to enable the rotor to rotate properly.
