Product Number: 12875N
The WAI 12875N is a brand-new 12V 110A Denso-design IR/IF alternator. It is replacing Denso original-equipment number 102211-3030 and Caterpillar reference 2035492 across six Caterpillar agricultural and industrial machine applications. It is engineered as a direct OE replacement, delivering the same electrical output as the unit it supersedes.
The IR/IF (internally regulated, internally fan-cooled) design keeps the regulator housed within the unit for a clean, self-contained installation. A clockwise rotation and groove pulley configuration match the drive setup of the machines it serves, ensuring a straightforward swap with no ancillary modifications.
The 12875N covers six Caterpillar Ag. & Ind. applications, including the D3G (2002–2006), D4G (2004–2006), D4G LGP (2002–2007), D4G XL (2002–2008), D5G (2002–2007), and D5G LGP (2002–2007). Cross-references span seven OE and aftermarket numbers across Denso, Caterpillar, CAT, and AD Kuhner — confirming broad catalogue coverage for this application.

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...
