The 24V 50A 270402220A/102110430 DENSO car alternator for TOYOTA DYNA DUTE JO5C SO5D ENGINE is a precision-engineered replacement part tailored for the TOYOTA DYNA DUTE models equipped with the JO5C and SO5D engine series. Designed to meet original equipment specifications, it delivers a reliable 24V DC output and a continuous 50A current, ensuring consistent power supply for the vehicle’s electrical systems—from lighting and ignition to auxiliary components.
Featuring an internal voltage regulator, this alternator automatically stabilizes output to prevent overcharging, safeguarding the battery and sensitive electronics. Its mechanical specifications are optimized for seamless integration: a 17mm diameter shaft ensures proper alignment with the engine’s drive system, while the 77mm twin-groove pulley (3/8” type) guarantees efficient power transfer, matching the original equipment’s rotational characteristics.
Installation is simplified by its pivoting/adjustable mount, designed for a 165mm spacing. The adjustment hole accepts an M8 fastener, and the pivot hole has a 10.5mm diameter, allowing for precise tensioning of the drive belt—critical for long-term performance and reducing wear on associated components. The +B output terminal uses an M6 fastener, ensuring secure electrical connection to the vehicle’s battery and wiring harness.
As a DENSO-manufactured component, it adheres to strict quality standards, offering durability in various operating conditions—from urban commutes to heavy-duty commercial use. Whether replacing a worn-out alternator or performing preventative maintenance, this unit ensures the TOYOTA DYNA DUTE’s electrical system operates reliably, minimizing downtime and maintaining vehicle performance.
