(1) Measure the resistance according to the value(s) in the table below. Standard Resistance: TESTER CONNECTION CONDITION SPECIFIED CONDITION Segment - Segment Always Below 1 Ω If the result is not as specified, replace the starter armature assembly. (c) Inspect the commutator for a short circuit. (1) Measure the resistance according to the value(s) in the table below. Standard Resistance: TESTER CONNECTION CONDITION SPECIFIED CONDITION Segment - Coil core Always 10 kΩ or higher If the result is not as specified, replace the starter armature assembly. (d) Using a vernier caliper, measure the commutator diameter. Standard diameter: 29.0 mm (1.14 in.) Minimum diameter: 28.0 mm (1.10 in.) HINT: Be sure to measure the commutator diameter at the ridges. If the diameter is less than the minimum, replace the starter armature assembly. (e) Check the commutator runout. (1) Place the armature shaft on V-blocks. (2) Using a dial indicator, measure the circle runout. Maximum commutator runout: 0.05 mm (0.00197 in.) If the commutator runout is more than the maximum, replace the starter armature assembly. 1UR-FE STARTING: STARTER (for 2.0 kW Type): INSPECTION; 20... |
