Product Number: 12581N
The WAI 12581N is a brand-new 12V 65A alternator. It is built to Magneti Marelli IR/EF specification, replacing Delco Remy DRA1147 and Magneti Marelli references including 63320124 and 63321458. It is matched to Ford and New Holland Industrial tractors — covering six confirmed applications including the Ford 4835, New Holland TL70, TL80, TL90, TL100, and New Holland Industrial 4835 — and carries cross-references from Hella, DRI, and New Holland OE.
Constructed to internal-regulator, external-fan (IR/EF) design, the unit delivers a clockwise-rotation output through a groove pulley, making it a direct-fit replacement for worn or failed original-equipment alternators on these platforms. Being brand new rather than remanufactured means there are no worn internals, no exchange surcharges, and no core to return.
The seven OE cross-references on record — spanning Delco Remy, Magneti Marelli, Hella, DRI, and New Holland — allow straightforward confirmation against an existing part number before ordering.

A. Yes. The WAI 12581N carries a confirmed cross-reference to Delco Remy DRA1147, as well as Magneti Marelli 63320124, Magneti Marelli 63321458, Hella 8EL749556001, DRI 519133652, New Holland 99478834, and New Holland R013240 — seven OE references in total. If you have one of these numbers on your old unit, this is the replacement. Use the selection widget or search our cross-referenced catalogue by OEM number to confirm your match, or ask Simon. Every fitment shown is backed by our Fit Guarantee.
A. This alternator fits six confirmed applications across Ford and New Holland Industrial: Ford 4835 (1995–1998), New Holland Industrial 4835 (1995–1998), New Holland Industrial TL70 (1998), New Holland Industrial TL80 (1998–2004), New Holland Industrial TL90 (1998–2004), and New Holland Industrial TL100 (1998–2000). Use the selection widget to match your exact model and year, or search by OEM number, and ask Simon if your machine is not listed. Fitment is backed by our Fit Guarantee.
A. IR/EF stands for Internal Regulator / External Fan. The voltage regulator is housed inside the alternator body rather than mounted separately on the machine, and the cooling fan sits on the outside of the unit. The WAI 12581N is built to this specification to match the original Marelli design used across the Ford and New Holland Industrial applications listed.
A. The WAI 12581N is brand new — not remanufactured or reconditioned. There are no worn internals, no exchange core to return, and no surcharge. It is supplied ready to fit.
A. The 12581N uses a groove pulley and runs clockwise rotation (CW). Confirm your existing alternator matches both the pulley type and the rotation direction before fitting, as these must correspond to your drive belt arrangement.
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.
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.
