Product Number: 12109N
The WAI 12109N is a brand-new 12V 35A alternator. It is built to an IR/EF (internally regulated, externally fan-cooled) design and manufactured as a direct replacement for Hitachi original-equipment units. With 30 OE cross-references spanning Hitachi, Bosch, Yanmar, Remy, Valeo, Prestolite, Hella, and DRI, it covers a wide spread of original fitments from a single, ready-to-fit unit.
The alternator runs a clockwise rotation and is fitted with a groove pulley, matching the belt-drive arrangement of the original Hitachi applications it replaces. Brand-new construction — not remanufactured — means every internal component is fresh from manufacture, so there is no question of inherited wear from a previous service life.
At 35 amperes output the unit is well matched to the lighter electrical loads typical of the agricultural and plant machinery for which Hitachi IR/EF alternators were widely specified. The IR/EF design keeps the regulator internal and the cooling fan external, giving a compact package that fits into the original mounting envelope without modification.
