• Q: How to overhaul the starter motor on 2006 Toyota Matrix?

  A: The overhauling process begins with disconnection of the lead wire followed by screw removal to release the magnet switch body from the motor. The continued operation involves extracting both the switch and return spring alongside plunger from the drive housing. Start by extracting the through bolts and then pull out the yoke with its associated starter commutator end frame before splitting them apart. To access the starter commutator end frame cover you must first separate the starter armature plate from the starter yoke after which you can use a screwdriver to carry out the removal process. A snap ring plier removes the snap ring while the washer and starter armature need to be taken out from the end frame. Extract first the three planetary gears from the starter center bearing clutch and next extract the starter center bearing clutch together with the starter drive lever set pin from the starter drive housing. The clutch requires removal of its starter drive lever set pin. Testing the magnet switch's body should confirm its operational status and resistance levels between terminals 50 and C at 1 Ohm or less and 50 to switch body at 2.0 Ohm or below. Replace the switch if standards are not met. Measure starter armature assembly resistance in three ways: the commutator segments must be under 1 Ohm while maintaining 10 kOhms or higher between the commutator and armature coil core; the components need replacement if these standards are not achieved. Use vernier calipers to measure the commutator depth between 3.1 mm and 3.8 mm after sanding off any burned areas with 400-grit sandpaper. Replace the component if the measurement exceeds the maximum value. The starter commutator end frame assembly must be checked for brush length which should be 9.0 mm but never less than 4.0 mm and the brush resistance should exceed 10 kOhms; any necessary repairs or replacements must be performed. Check the starter center bearing clutch sub-assembly for operation quality by observing the clutch pinion gear which should rotate freely clockwise and lock counterclockwise; replace if the parts exhibit wear or damage. The starter drive lever set pin must go into the starter center bearing clutch before installing the clutch into the starter drive housing. You should apply grease onto planetary gears before placing them inside the starter center bearing clutch. When assembling the starter armature piece apply grease to the washer and shaft then mount them into the starter commutator end frame before attaching a new snap ring and checking that the length stays below 5.0 mm. Install the starter commutator end frame cover afterward to put the starter armature plate together with the starter commutator end frame inside the starter yoke. To complete installation, physicians should first align the starter yoke properly with the starter drive housing then tighten the through bolts to 6.0 N.m. Afterward they must install the magnet switch body by applying grease to the plunger and hook before hanging the plunger hook onto the starter drive lever set pin. The plunger requires installation with the return spring before securing the magnet switch with screws to 7.5 N.m and connecting the lead wire to terminal C with a nut tightened to 10 N.m.
