• Q: How to overhaul the starter motor on 2004 Toyota Camry?

  A: Start the starter motor overhaul by removing the magnetic switch assembly through wire detachment and screw removal which secures it to the starter drive housing before separating the magnetic switch and its return spring along with the plunger. Start the procedure by removing two through-bolts which enables separation of the field frame assembly holding the commutator end frame. Finally extract the field frame from the commutator end frame. Use a screwdriver to remove the starter armature plate from the field frame followed by the removal of the commutator end frame cover. To remove the starter armature assembly the snap ring and plate washer should be extracted using snap ring pliers followed by removing the armature at the commutator end frame. Extract the three planetary gears which are present inside the starter drive housing assembly. Check plunger speed returning during inspection as well as measure the resistance between pull-in coil terminals 50 and C (standard: below 1 Ohm) and measure the hold-in coil resistance between terminal 50 and the switch body (standard resistance: below 2 Ohm). Examine the starter armature assembly by verifying the commutator has open circuits (less than 1 Ohm standard) and lacks ground connection (minimum 10 k Ohm) while you should clean any discolorations or contaminants with sandpaper (grade No.400) or a lathe machine. Also confirm the commutator extends the exact length of 3.1 to 3.8 mm. To inspect the starter commutator end frame cover, verify that the brushes extend 4.0 to 9.0 mm in length along with meeting the standard of 10 k Ohm or higher insulation. Check the starter clutch function through counterclockwise clutch pinion gear rotation followed by a verification of its locking ability when turning the gear clockwise. Apply grease to the planetary gears together with their corresponding pin parts of the planetary shaft before adding the three planetary gears. After applying grease to the plate washer and armature shaft you should install the starter armature into the commutator end frame while using a new snap ring to secure it after measuring its length which should be no more than 5.0 mm. First attach the end frame cover to the commutator end frame structure then insert the armature plate into the starter field frame while aligning the keyway with the key inside before placing the starter plate streaking. Fasten the end frame rubber to its matching cutout of the field frame followed by end frame installation while the starter drive housing cutout matches with the protruding part of the field frame through two through bolts with 6.0 Nm torque limit. The concluding steps involve applying grease to the plunger and hook of the magnetic switch and hanging the plunger hook on the drive lever before installing the plunger with its return spring and securing the magnetic switch with screws torqued to 7.5 Nm then connecting the lead wire to the magnetic switch through the nut which will be torqued to 10 Nm.
