Product Number: 12272N
The WAI 12272N is a brand-new 12V 80A alternator. It is built to replace Hitachi original-equipment units including LR180-03, LR180-03A and LR180-03B, as well as Yanmar OE references 119573-77200, 119573-77201 and 129470-77200. It covers 17 cross-references in total, spanning Hitachi, Yanmar, Remy, Prestolite Electric and DRI fitments — making it a well-supported direct-replacement choice for plant and agricultural machinery.
The 12272N is manufactured to an IR/EF (internal regulator, end-frame) design, which integrates the voltage regulator within the alternator body for a clean, self-contained installation. Clockwise rotation and a groove pulley configuration match the original Hitachi drive-belt arrangement, so no modification to the belt path or tensioner is required on a like-for-like swap. At 80 amperes output the unit delivers the charging capacity of the OE part it replaces.
Supplied brand new — not remanufactured — the 12272N is ready to fit straight from the box without the uncertainty of a reconditioned unit.

A. The 12272N is a direct replacement for the following Hitachi OE references: LR180-03, LR180-03A, LR180-03B, LR180-03C, LR18003, LR18003A, LR18003B and LR18003C — eight Hitachi numbers in total. To confirm it is correct for your machine, search our cross-referenced catalogue by OE number or ask Simon.
A. Yes. The WAI 12272N covers six Yanmar OE references: YANMAR 119573-77200, YANMAR 119573-77201, YANMAR 129470-77200, Yanmar 11957377200, Yanmar 11957377201 and Yanmar 12947077200. Search our catalogue by your Yanmar part number to verify the match, or ask Simon if you need help cross-referencing your machine.
A. In addition to Hitachi and Yanmar, the 12272N covers Remy RA00119, Prestolite Electric 20150112 and DRI 582112802, bringing the total to 17 cross-references across five brands. Search our catalogue by any of these numbers to confirm suitability for your application.
A. The WAI 12272N is rated at 12V and 80A output, matching the specification of the original Hitachi IR/EF unit it replaces. It uses a clockwise rotation and a groove pulley, consistent with the OE drive-belt layout.
A. IR/EF stands for Internal Regulator / End-Frame mounting. The voltage regulator is built inside the alternator body rather than fitted externally, and the unit mounts at the end frame. This matches the original Hitachi design, so installation is a straightforward like-for-like swap.
A. The WAI 12272N is supplied brand new — not remanufactured or reconditioned — so it arrives ready to fit without any concerns about prior wear or unknown service history.
A. The 12272N uses clockwise (CW) rotation and a groove pulley, which replicates the original Hitachi configuration. No modifications to the belt path or tensioner should be needed on a direct like-for-like replacement.
A. Warranty details are shown in the product tech specs or datasheet where available. Contact us if warranty is not stated on the listing.
