Electric Starter Maintenance for 2011 Yamaha Raptor 125 ATVs
Ensure your 2011 Yamaha Raptor 125 ATV's electric starter motor is in optimal condition with these maintenance steps:
- Inspect the Commutator: Clean any dirt from the commutator using 600 grit sandpaper. Measure the commutator diameter and check for continuity using a digital circuit tester. If out of specification, replace the starter motor.
- Check Armature Assembly: Measure the armature assembly resistances using a digital circuit tester. If any resistance is out of specification, replace the starter motor.
- Verify Mica Undercut: Measure the mica undercut and scrape it to the proper measurement with a grounded hacksaw blade if out of specification.
- Inspect Brush Length: Measure the brush length and replace the brushes as a set if out of specification.
Remember, maintaining the commutator's mica undercut is crucial for proper operation. If any component is out of specification during inspection, it's best to replace the starter motor to ensure reliable performance.
