2006 Toyota Corolla Starter Motor Parts Q&A

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

  A: The starter motor overhaul begins with detachments of the magnet switch body undergoing lead wire separation and screw removal before extracting the starter drive housing's magnet switch and return spring and plunger. Start by detaching through bolts and using force to pull out the yoke with its attached starter commutator end frame until the components separate. You should first remove the starter armature plate from the starter yoke before using a screwdriver to detach the starter commutator end frame cover. Snap ring pliers will extract the snap ring from the end frame while the starter armature assembly also requires removal of the washer before extraction from the end frame. You should obtain the starter center bearing clutch after removing its three planetary gears from the starter drive housing. Then extract the starter drive housing along with the drive lever set pin and the center bearing clutch unit. The starter drive lever set pin should be removed from the clutch. The magnet switch body needs inspection to check operation and electric resistance until it reaches the required standards; terminal 50 with C should show less than 1 Ohm while terminal 50 with the switch body must show less than 2 Ohms; replace the switch body if necessary. The starter's armature commutator must have resistances of 1 Ohm or lower between each segment which must be verified separately or highest resistance must exceed 10 kOhm between commutator and coil core then replacement is needed. Use vernier calipers to measure the commutator depth then smooth the surface with sandpaper if needed to check for dirt or burn before replacement if the measurement exceeds maximum standards between 3.1 mm and 3.8 mm. A Starter commutator end frame assembly requires brush length measurement should be between 4.0 mm and 9.0 mm while the resistance between positive and negative brushes must be 10 kOhm or higher, if any other values are found replace the brush holder. Assess the starter center bearing clutch sub-assembly for operation by verifying that the clutch pinion gear turns freely clockwise along with locking counterclockwise motion; replace if needed. Insert the starter drive lever set pin into the starter center bearing clutch and fit the clutch inside the starter drive housing. Apply grease to both planetary gears and their shaft pins prior to mounting the three planetary gears onto the starter center bearing clutch. According to operating procedures, place grease on both the starter armature shaft and washer followed by armature and washer installation onto the starter commutator end frame. Utilize snap ring pliers to install a new snap ring before checking its length to prevent exceeding 5.0 mm since replacement may be needed. First install the starter commutator end frame cover to the end frame after which you should align the starter armature plate to the starter yoke. Fit the rubber part within the starter yoke cutout before mounting the starter commutator end frame onto the yoke. The final step involves placing the key of the starter yoke into the starter drive housing keyway before attaching the yoke and tightening its through bolts to 6.0 N.m torque. The magnet switch body requires insulation grease on both its plunger and hook elements followed by plunger hook placement on the starter drive lever set pin while inserting plunger with spring then fastening screw bolts to 7.5 N.m for secure terminal C lead wire connection using a 10 N.m nut.
