  Q: How to replace the starter motor on Chevrolet Metro?

  A:

  The first step to change the Starter motor is to disconnect the negative (-) word from the battery. Next, you should take the retaining nut and the positive Battery Cable and take them away from the Starter Solenoid and then proceed to disconnected the solenoid electrical connector. Trade the two mounting bolts off and pull out the Starter motor assembly from the automobile. Par for installation, fasten the Starter motor assembly back to the vehicle using two mounting bolts and tighten them to 23 n.m (17 lb ft). Connect the solenoid electrical connector and introduce the battery positive terminal cable into the solenoid with a retaining nut at 10 n.m (89 lb in). Lastly, attach the negative (-) battery cable and tighten the negative (-) battery cable-to-negative (-) battery terminal retainer to a torque of 15 n.m (11 lb ft).

  Q: What tools are required to service and repair the starter motor on Chevrolet Metro?

  A:

  The required tools for fixing Starter motors consist of tension scale (J 544-01), dial indicator (J 8001), magnetic base (J 26900-13), vernier caliper (J 26900-5), and digital multimeter (J 39200). First clean all Starter motor components while sanding away burn marks and clearing dirt from the commutator end of the Armature by using #300 or #400 grit sandpaper followed by wiping with a clean cloth. Set the Armature on v-blocks then use the dial indicator (J 8001) along with the magnetic base (J 26900-13) to determine commutator run-out; discard the Armature if it exceeds 0.40 mm (0.016 in). Use the vernier caliper (J 26900-5) to check the commutator outside diameter then replace the Armature if the measurement falls below the specified minimum diameter for automatic or manual transaxle requirements. The Armature needs replacement when commutator insulation depth falls below 0.2 mm (0.008 in). The digital multimeter (J 39200) should be used to check the core to commutator resistance which must be below 5.0 ohms for the Armature to remain in service. Test the commutator segment-to-segment resistance levels until reaching 5.0 ohms and replace the Armature when this value is exceeded. The test for manual transaxle field coils requires measuring resistance between lead wires and the yoke component; replace the yoke if resistance is at 5 ohms or below. The brush requires replacement through vernier caliper (J 26900-5) measurements when its length falls below specification. The digital multimeter (J 39200) should be used to measure resistance between positive and negative brush holders. Replace the brush holder whenever the measured resistance falls below 5.0 ohms. The brush spring tension needs to be checked with j 544-01 tension scale to replace the spring when maintained tension goes below the minimum level. Use the digital multimeter (J 39200) to check the pull-in and hold-in coils resistance of the Starter Solenoid. Replace the solenoid when either resistance passes 5.0 ohms. Check and replace all components of pinion drive lever, overrunning clutch, Armature bushing and bearings when signs of wear or damage emerge. The maintenance process concludes with an evaluation of the internal gear assembly, idle gears, brush springs, brush holder and positive plate insulation before changing all affected components displaying signs of wear or damage.
