Product Number: 12770N
The WAI 12770N is a brand-new 24V 95A brushless alternator. It is built to Denso IR/EF specification, supplied without pulley and designed to replace original-equipment units across 108 Caterpillar agricultural and industrial applications. It is the direct replacement for Denso part numbers including 101211-8400, 101211-8401 and 101211-8460, as well as Delco Remy DRA0687, Caterpillar 2267683 and 2357133, and Perkins 2871A703 — 18 cross-references in total.
Brushless IR/EF (internally regulated, externally fused) construction eliminates the brush gear that causes wear in conventional designs, reducing maintenance requirements and extending service life in demanding plant and agricultural environments. Clockwise rotation matches the original Denso specification, and the unit ships without pulley so the existing pulley assembly is retained during fitment — keeping the job straightforward.
Confirmed fitment covers Caterpillar Ag. & Ind. machines including the 140H (1996–2011), 143H (1998–2007), 14H (2005–2008), 160H (1996–2006), 163H (1997–2006), 16H (1998–2007), 2384C (2012–2014) and 2470C (2006–2011), among 108 applications catalogued in total.

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 12770N is a 24V, 95A unit with clockwise (CW) rotation. It is a brushless IR/EF (internally regulated, externally fused) design and is supplied without pulley, so you reuse the existing pulley assembly during installation.
A. The WAI 12770N is listed as supplied without pulley (w/o Pulley). This means your existing pulley is transferred across at fitment, which is standard practice for direct-replacement Denso-type alternators of this specification. Check that your current pulley is serviceable before installation.
A. A brushless IR/EF alternator has no carbon brush gear to wear down, which reduces maintenance intervals and improves reliability in demanding plant and agricultural environments where the alternator may be subject to vibration, dust and extended running hours. Internal regulation (IR) and external fusing (EF) are standard features of the original Denso specification this unit is built to match.
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.
