Product Number: 12474N
The WAI 12474N is a brand-new 12V 90A Denso-design alternator. It is built to replace Denso original-equipment units including reference 102211-1180 and John Deere units referenced as RE500227 and SE501836. It is a direct aftermarket replacement for Denso IR/IF (internally regulated, internally fused) alternators and is suited to John Deere agricultural equipment that specifies this unit.
Constructed to IR/IF specification, the alternator integrates its voltage regulator and field circuit internally, which simplifies installation and eliminates the need for an external regulator. It produces a clockwise rotation and is fitted with a groove pulley to match the belt drive arrangement of the original application. The 90-amp output delivers ample charge capacity for vehicles and machines with moderate electrical demand.
As a brand-new unit — not remanufactured — it carries full component integrity with no hours of prior service. WAI is a recognised manufacturer of rotating electrics, and this alternator is produced to meet the design parameters of the Denso original it replaces.

Exploring the WAI Starter Motor and Alternator at Partsformachines.com Introduction: In the Plant and Agriculture sector, a starter motor and alternator are parts that ensure a machine runs smoothly. At Partsformachines.com we have partnered with WAI, a global manufacturer of auto and plant machinery parts to off...
The best way to find the correct starter motor is to combine the machine and engine details with the OEM or original starter reference, then confirm voltage, rotation, pinion teeth, mounting and terminal position. Do not choose a replacement from appearance alone.
A starter motor usually clicks without cranking because the battery cannot deliver enough current, resistance is present in the battery cables or engine ground, or the starter control circuit and solenoid are not operating correctly. A click does not automatically mean the...

A. The WAI 12474N is cross-referenced to four OE references: Denso 102211-1180, Denso OEM 1022111180, John Deere RE500227, and John Deere SE501836. All four references are covered. To confirm fitment to your specific machine, search our cross-referenced catalogue by OEM number or machine model, or ask Simon.
A. Fitment is defined by the OE cross-references: this unit replaces Denso and John Deere original-equipment alternators carrying references 102211-1180, 1022111180, RE500227, and SE501836. Specific machine model listings are not published for this part. Search our catalogue by your OEM number or machine model to verify fit, or ask Simon. Fitment shown is backed by our Fit Guarantee.
A. The WAI 12474N is brand new — not remanufactured or reconditioned. It carries no prior service hours and is built to meet the design parameters of the Denso original-equipment unit it replaces.
A. It is a 12-volt, 90-amp unit built to Denso IR/IF (internally regulated, internally fused) specification. Rotation is clockwise and the pulley is a groove-type to match the original belt drive arrangement. No external voltage regulator is required.
A. IR/IF stands for Internally Regulated / Internally Fused. This means the voltage regulator is built into the alternator body rather than mounted separately, and the field circuit is fused internally. It simplifies the installation compared with externally regulated designs and is a direct match for the Denso original-equipment configuration this unit replaces.
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.
