Tacoma 2WD V6-4.0L (1GR-FE) (2006)
Starter Motor: Testing and Inspection
INSPECTION
1. INSPECT STARTER ARMATURE ASSEMBLY
a. Check the commutator for an open circuit.
1. Using an ohmmeter, measure the resistance between the segments of the commutator.
Standard: 1 Ohm or lower
If the result is not as specified, replace the starter armature.
b. Check the commutator for ground.
1. Using an ohmmeter, measure the resistance between the commutator and armature coil core.
Standard: 10 k Ohm or higher
If the result is not as specified, replace the starter armature.
c. Check whether the commutator surface is dirty or burnt. If necessary, clean it with sandpaper (No. 400) or a lathe.
d. Check the commutator for runout.
1. Place the commutator on V-blocks.
2. Using a dial gauge, measure the runout.
Maximum runout: 0.05 mm (0.0020 in.)
If the runout is greater than the maximum, correct it on a lathe.
