Product Number: 12112N
The WAI 12112N is a brand-new 12V 50A alternator. It is built to replace Hitachi original-equipment units, including Hitachi LR140-714, Hitachi LR140-721, and Hitachi GD001927E, across a catalogue of 78 OE and aftermarket cross-references. Designed to the IR/IF (internal regulator, internal fan) specification, it is a direct-fit replacement for John Deere compact and skid-steer models, Takeuchi machinery, and Samsung construction equipment.
Constructed to Hitachi's original design parameters, the 12112N features internal regulation for simplified installation and a groove pulley matched to factory drive belt arrangements. Clockwise rotation is confirmed at the drive end, ensuring correct fitment without modification. The internal fan design keeps the unit self-contained and reduces external contamination risk — an important consideration in the dusty and damp conditions typical of agricultural and plant environments.
With 50 amps of output at 12 volts, this alternator is suited to the electrical demands of the John Deere 3012, 3015, 4020, 4475, 5575, 6675, and 7775 platforms (spanning model years 1992 to 1998), the Samsung SE50-3, and compatible Takeuchi machines — 9 confirmed applications in total. Cross-references also cover Bosch Exchange 0986035451, Bosch USA AL5045N, and Delco Remy DRA3218 among the 78 verified references.

John Deere applications include the 3012, 3015, 4020, 4475 (1994–1998), 5575 (1995–1998), 6675 (1994–1998), and 7775 (1994–1998). Samsung SE50-3 (1992–1998) and one Takeuchi model are also covered.

A. Yes. Beyond the Hitachi references, the 78-ref catalogue includes Bosch Exchange 0986035451 and Bosch USA AL5045N, as well as Delco Remy DRA3218. If your existing unit carries one of these numbers, the WAI 12112N is the confirmed cross-reference. Search our catalogue by OEM number or ask Simon to verify any reference not listed here.
A. This is a brand-new 12V, 50-amp alternator built to the IR/IF (internal regulator, internal fan) design. Rotation is clockwise (CW) at the drive end and the unit uses a groove pulley. The IR/IF design means the voltage regulator is fully internal, simplifying installation with no external regulator wiring required.
A. IR/IF stands for Internal Regulator / Internal Fan. The internal regulator means the voltage regulation circuit is built inside the alternator casing — there is no separate external regulator to wire or mount. The internal fan keeps the unit self-contained and reduces exposure to external debris. Provided the application match is confirmed, the WAI 12112N installs as a straightforward like-for-like swap for any IR/IF Hitachi unit it replaces.
A. The WAI 12112N is supplied brand new — not remanufactured, reconditioned, or exchange. No core return or surcharge applies.
A. The confirmed John Deere applications for this alternator are the 3012, 3015, 4020, 4475, 5575, 6675, and 7775 models. Fitment to a specific engine variant such as the 6068 is not confirmed in the published data for this part. Use the selection widget to match your engine variant, search by your existing OE part number, or ask Simon to check compatibility before ordering.
A. Yes. Every vehicle and OE cross-reference shown for this part is checked against manufacturer data and backed by our Fit Guarantee. If it is not right, our Fit Guarantee or hassle-free returns have you covered.
A. Use the selection widget to match your make, model and engine, or search our cross-referenced catalogue by OEM number, machine model or equivalent part across brands. If your vehicle is not listed, ask Simon. Every fitment shown is backed by our Fit Guarantee.
