2000 Toyota Land Cruiser Alternator Parts Q&A

• Q: How to disassemble and reassemble the Alternator, including the steps for replacing the front and rear bearings on 2000 Toyota Land Cruiser?

  A: Disassembly of the generator begins with removing the 100 A model generator cover and cord clip using bolt and nut tools while models without Canada specifications require only bolt and cord clip removal. The next step requires removing the rear end cover through this sequence: First separate the nut and terminal insulator and three nuts followed by unfastening the two nuts and bolt and plate terminal. The brush holder cover requires removal first before subsequent removal of five screws, brush holder and voltage regulator followed by extraction of the seal plate from the rectifier end frame. The four screws allow removal of the rectifier holder along with its attached four rubber insulators. Use Special Service Tool 09820-63010 with a torque wrench and tighten the socket clockwise to 39 Nm (400 kgf.cm, 29 ft.lbf) while securing the tool to the rotor shaft and mount the adapter into a vise before installing the generator to the adapter. The pulley nut can be loosened through counter-clockwise tool rotation yet careful not to exceed a half turn since it might damage the rotor shaft. Following this step, remove the generator together with the tool from the adapter. Special Service Tool 09286-46011 removes the rectifier end frame along with the generator washer after disconnecting nuts and cord clip fittings on the 80 A model while leaving only the nuts exposed for the 100 A model. The drive end frame should be placed on the pulley followed by the rotor installation before setting the rectifier end frame and applying the generator washer on the rotor followed by frame press-in using a 29 mm socket wrench. When installing the cord plug together with four nuts on the 80 A model maintain a torque of 4.5 Nm (46 kg.cm, 40 in.lb) yet install these four nuts only for the 100 A model with the same torque value. Use the pulley holding tool to fasten the nut after manual tightening and verify its security at 39 N.m (400 kgf.cm, 29 ft.lbf). Move the generator to the adapter once you tighten the pulley nut to 110.5 N.m (1,128 kgf.cm, 81 ft.lbf). Fasten the rectifier holder to its place using four rubber insulators while tightening the four screws to 2.94 Nm (30 kg.cm, 26 in.lb). Screw the seal plate onto the rectifier end frame afterwards add the voltage regulator and brush holder in the correct position using five 2.0 Nm (20 kg.cm, 17 in.lb) torques. The rear end cover requires two nuts and one bolt for assembly while the bolt gets torqued at 3.8 Nm (39 kg.cm, 34 in.lb) and the nuts reach 4.4 Nm (45 kg.cm, 39 in.lb) before installing the terminal insulator with a nut at 4.1 Nm (42 kg.cm, 36 in.lb). The 100 A model requires users to fasten the generator cover with cord clip through a bolt and nut at 16.6 Nm (170 kg.cm, 12 ft.lb) for Canada and without the bolt for non-Canada versions. Verify the rotor moves without resistance during its rotation. A new front bearing requires removal of four screws and bearing retainer before expulsion through Special Service Tool O9950-60010 (09951-00260, 09952-06010). Insert the new bearing with Special Service Tool 09950-60010 (09951-00500) and fasten the bearing retainer with four screws at 3.0 Nm (31 kg.cm, 27 in.lb). The correct substitution method for the rear bearing starts with disassembly of bearing cover and bearing using Special Service Tool 09820-00021 followed by applying the inside bearing cover to the rotor before using Special Service Tool 09820-00030 to insert the new bearing and finally using Special Service Tool 09285-76010 to install the outer bearing cover.
