Product Number: 7186-12N-105A
The WAI 7186-12N-105A is a brand-new 12V 105A alternator. It is built to the Delco 10SI/116 Series IR/EF design, covering an exceptionally wide range of agricultural, construction, and industrial machines. With 141 OE cross-references on record — including Bosch USA AL5007X, Delco 1102920, Delco 1102921, Delco 1102925, and Hyster 344235 — this unit is a direct OE replacement for machines across Case, Caterpillar, John Deere, Clark, Allis Chalmers, International, Bobcat, Massey Ferguson, Hyster, and many other makes, spanning 550+ verified applications in total.
Clockwise rotation and a groove pulley configuration match the original Delco specification precisely, so the alternator drops into place without modification. As a brand-new unit rather than a remanufactured exchange, there are no core charges and no concerns about the condition of internal components — what you receive is a fresh-built alternator ready to install.
The 10SI/116 Series IR/EF (internal regulator, external fan) architecture is one of the most widely deployed alternator platforms in heavy-equipment history, making this WAI replacement an authoritative fit for a broad cross-section of older fleet machines that remain in daily service.

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. This is a brand-new 12V, 105A alternator built to the Delco 10SI/116 Series IR/EF specification — internal regulator, external fan. Rotation is clockwise (CW) and the pulley is a groove type. These are the original Delco design parameters, so no adaption is required when replacing a like-for-like unit.
A. The WAI 7186-12N-105A is supplied brand new. It is not a remanufactured or reconditioned exchange unit, so there are no core return requirements and no uncertainty about the condition of internal components.
A. 10SI refers to the Delco Remy series designation — one of the most widely used alternator platforms in agricultural and construction equipment. IR stands for internal regulator (the voltage regulator is built into the alternator body) and EF stands for external fan (the cooling fan sits outside the case). The 116 denotes the frame size. Together these define the mounting, wiring, and mechanical interface of the unit, confirming direct interchangeability with any original 10SI/116 IR/EF-specification alternator.
