Product Number: 12579N
The WAI 12579N is a brand-new 12V 120A alternator. It is built to Bosch IR/IF specification, replacing Bosch original-equipment reference 0 124 515 120. It also crosses to Case references 2855914 and Case LH 2855914, as well as New Holland 47129299, AD Kuhner 301894, and Farcom 112724, making it a direct OE-equivalent replacement for plant and agricultural equipment running Bosch-designed charging systems.
Constructed to IR/IF (internal regulator, internally fan-cooled) design, the unit delivers a regulated 120-amp output at 12 volts — providing the charging capacity demanded by equipment with high electrical loads. The groove pulley is fitted as standard, matching the belt drive configuration of the original Bosch unit it replaces.
As a brand-new alternator — not remanufactured — the 12579N offers consistent out-of-box performance without the variability that can accompany exchange units. WAI is a recognised manufacturer in the rotating electrics sector, supplying to both trade and independent workshops.
