Product Number: 7186-3N
The WAI 7186-3N is a brand-new 12V 72A alternator. It is built to the Delco 10SI/116 Series IR/EF specification, replacing original-equipment Delco and Remy units across a wide range of agricultural, construction, and industrial machines. It is a direct-fit solution for operators needing a reliable, specification-matched replacement without compromising on electrical output.
Constructed to the internally regulated, externally fanned (IR/EF) 10SI/116 design that Delco established as a workhorse standard across decades of heavy-duty plant and agricultural equipment, this alternator delivers a steady 72A output at 12V. It is supplied with a groove pulley and arrives ready to fit straight from the box — no modification required.
With 49 OE cross-references spanning Delco and Remy part numbers, this unit covers an extensive range of applications. Fitment extends across more than 390 recorded vehicle applications, including machines from International, Clark, Allis Chalmers, Case, White Industrial, Baker, Massey Ferguson, John Deere, Bobcat, Ford, and many others. Sample applications include the Allis Chalmers 6060, 6070, and 6080 series (1980–1986), along with the Allis Chalmers 2800 Mark I and 2900 Mark II.

A. The WAI 7186-3N is a 12-volt alternator with a 72-amp output, built to the Delco 10SI/116 Series IR/EF design — internally regulated and externally fanned. It is fitted with a groove pulley and is supplied brand new.
A. The 10SI/116 Series is a Delco alternator platform widely used across agricultural and construction equipment over many decades. IR stands for internally regulated, meaning the voltage regulator is built into the alternator body rather than mounted separately on the machine. EF stands for externally fanned, referring to the cooling fan arrangement on the pulley end of the unit. Together, these design features define the mounting, connector, and wiring configuration — so matching the correct series is essential for a direct-fit replacement.
A. The WAI 7186-3N is supplied brand new — not remanufactured, reconditioned, or exchange.
