FAQ

Q: Is this alternator a direct replacement for my Yuchai YC6J125Z engine?
A: Yes, the JFZ2902T (A3008-3701100) is the standard OEM alternator for the YC6J125Z-T20 engine. It matches the original mounting points, pulley alignment, and electrical connector, allowing for a direct bolt-on installation.

Q: What is the recommended installation procedure?
A: Always disconnect the negative battery terminal before starting. Remove the old alternator, transfer the pulley if necessary (ensure correct torque), and install the new unit in reverse order. Check belt tension and ensure all electrical connections are clean and tight. We recommend a professional mechanic perform the installation.

Q: How can I maintain this alternator for a longer service life?
A: Regularly inspect the drive belt for wear and proper tension. Keep the alternator clean and free of debris, oil, and moisture. Periodically check all wiring connections for corrosion or looseness. If the battery warning light flickers, have the charging system tested immediately to prevent premature failure.
