Product Number: 12558N
The WAI 12558N is a brand-new 12V 50A alternator. It is built to the Mitsubishi IR/IF design specification, replacing original-equipment numbers including Mitsubishi A7T02071C, Mitsubishi 31A68-00400, and Mitsubishi A007T02071 — 25 OE cross-references in total, spanning Mitsubishi, Delco Remy, Remy, AD Kuhner, Farcom, Sando, and others. It is a purpose-built replacement for compact plant equipment, fitting Cub Cadet and Caterpillar Ag. & Ind. models across 12 verified applications.
The unit delivers 50 amps of charging output at 12 volts, uses an internally regulated, internally excited (IR/IF) circuit architecture, and mounts with a clockwise-rotation groove pulley — key details to cross-check against the original alternator before ordering.
As a brand-new unit, the 12558N avoids the unknowns that come with a remanufactured or reconditioned part. The groove pulley is ready to accept a standard serpentine or V-belt drive without adaptation.

A. The WAI 12558N replaces 25 OE cross-references across multiple brands. Mitsubishi numbers on this part include A7T02071C, 31A68-00400, 31A68-00401, 31A68-00402, A007T02071, A007T02071A, A007T02071C, A007TA1472AM, A7T02071, A7T02071A, A7T02071C, A7TA1472AM, 31A6800400, 31A6800401, and 31A6800402 — among others. To search the full list by OEM number or machine model, use our cross-referenced catalogue or ask Simon. Every OE reference shown is backed by our Fit Guarantee.
A. Yes. The WAI 12558N cross-references to Delco Remy DRA0408 and Remy 19091008. If your machine currently carries either of those part numbers, the 12558N is the confirmed replacement. Use the cross-reference search or ask Simon to verify against your specific application.
A. It fits Cub Cadet and Caterpillar Ag. & Ind. models — 12 verified applications in total. Cub Cadet applications include the 7000, 7200, 7205, and 7260 (1998–2003). Caterpillar Ag. & Ind. applications include the 302.5C, 303, 304CR, and 305CR Mini Excavators. Use the selection widget to match your exact make, model, and engine variant, or search by OEM number. Every fitment shown is backed by our Fit Guarantee.
A. The WAI 12558N is a 12-volt, 50-amp alternator with an IR/IF (internally regulated, internally excited) design. Rotation is clockwise (CW) and the unit is fitted with a groove pulley. It is supplied brand new — not remanufactured or reconditioned.
A. IR/IF stands for Internal Regulator / Internal Field — meaning the voltage regulator and field excitation circuit are both housed within the alternator body rather than mounted externally. This design must match your original unit; fitting an alternator with a different regulation architecture to your machine's wiring will cause charging faults. Always confirm your original alternator is also IR/IF before ordering.
A. The WAI 12558N is supplied complete with a groove pulley fitted as standard. No pulley transfer from your old unit is required, but confirm that the groove profile matches your drive belt before installation.
A. Yes — ask Simon, or WhatsApp our team on 07754 288583 with any questions about specifications, suitability, or compatibility.
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.
