Product Number: 12485N
The WAI 12485N is a brand-new 12V 40A alternator. It is built to Hitachi IR/IF specification, replacing Hitachi original-equipment units referenced as LR140-708, LR140-708C, LR140-708CN and their variants, as well as Honda OE numbers including 31100-MT2-005, 31100-MT2-015 and 31100-MT2-0150, and the Remy equivalent RA00118. Thirteen OE cross-references are held against this part in total.
The IR/IF (internal regulator/internal fan) design keeps the unit self-contained and straightforward to install, with clockwise rotation matching the original Hitachi specification. Being supplied brand new rather than remanufactured means there are no worn brushes, degraded bearings, or reconditioned windings to contend with — the unit arrives ready to fit without any core exchange requirement.
With a 40-amp output at 12 volts, the 12485N is suited to applications where Hitachi originally specified this alternator family. Cross-reference your OE number against the 13 verified references held for this part to confirm suitability before ordering.
