Product Number: 12471N
The WAI 12471N is a brand-new 12V 90A alternator. It is built to Denso IR/IF specification, replacing original-equipment Denso units — including reference 102211-1820 — fitted to Caterpillar agricultural and industrial machines. It is designed as a direct replacement for the Denso and Caterpillar OE alternators listed below, covering two confirmed Caterpillar Ag. & Ind. applications: the 902 (1998–2005) and the 906 (1998–2008).
The IR/IF (internal regulator, internal fan) design keeps all regulation electronics self-contained within the unit, eliminating the need for an external regulator and simplifying installation. The groove pulley is compatible with the standard belt drive arrangement on these machines, and the brand-new condition means no remanufactured wear or residual service hours.

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...
