Product Number: 66031003
The Highway Automotive 66031003 is a 24-volt, 80-amp alternator designed as a direct replacement for MAN commercial vehicle applications. Supplied without belt pulley, it is suited to workshop fitting where the original pulley is being retained or transferred from the outgoing unit. Rated at 24 V and 80 A, the 66031003 meets the charging demands of heavy-duty MAN truck platforms. The absence of a belt pulley keeps the unit true to OE specification when the existing pulley is serviceable, avoiding unnecessary hardware changes during a straightforward alternator swap. This alternator covers 23 applications across the MAN TGA, TGL, TGM, TGS I, and TGX I ranges, spanning engine variants including the D0834, D0836, D20, D26, D28, D2868, D1556, D2676, and D3876. The breadth of coverage makes it a practical stock item for fleets and workshops servicing the MAN heavy truck lineup. In the box: one Highway Automotive 66031003 alternator (no belt pulley). Manufactured to Highway Automotive standards; see platform technical specifications for further detail.
