Quality-Built 140-14104 HD Heavy Duty Remanufactured Alternator

The Quality-Built 140-14104 is a heavy-duty remanufactured alternator engineered to deliver dependable charging performance for demanding applications. Manufactured by Motor Car Parts of America (MPA), one of the world's largest remanufacturers of import and domestic starters and alternators, this HD unit is built to exceed OEM specifications — not just meet them.

Key Features:

• Heavy-Duty (HD) Construction: Upgraded internal components designed to handle higher electrical loads and harsh operating conditions beyond standard-duty applications
• 100% Electronically Tested Rotor: Coated with high-dielectric insulation for maximum durability and reliable charging output
• New Brushes & Springs: Premium lead-free brushes and new springs installed to ensure long service life and consistent performance
• Load-Tested Rectifier: Heavy-duty rectifier diodes verified under load to ensure sustained alternator output and longevity
• Electronically Tested Stator: Verified for maximum insulation quality and proper phase balance
• Inspected or New Bearings: Packed with high-temperature grease to reduce heat buildup and minimize friction
• OE-Quality Terminals: High-temperature insulators ensure secure, reliable electrical connections
• Cleaned & Re-Tapped Housing: 100% blast-cleaned housings with inspected and re-tapped mounting threads for proper torque and easy installation
• Corrosion-Resistant Pulley: Plated or powder-coated pulley provides maximum protection against rust and corrosion
• Precision-Polished Slip Rings: Optimized for maximum output efficiency
• QS-9000 Quality Standards: Manufactured under the highest quality guidelines required by major OEM automotive suppliers

Quality-Built HD alternators are re-engineered — not simply rebuilt — to withstand the rigors of heavy-duty use, including extreme temperatures and high variable electrical loads from modern vehicle accessories and upfitted equipment. Each unit undergoes individual end-of-line load testing to verify performance across a full range of operating conditions before leaving the facility.
