Product Number: 8721N-150A
The WAI 8721N-150A is a brand-new 12V, 150A alternator. It is built to the Delco 11SI Series IR/IF specification, designed as a direct replacement for Powerite Automotive reference 8721. It is compatible with Case and New Holland Industrial plant machinery, making it a practical choice for operators running compact track loaders and skid steers across these fleets.
Constructed to the internally regulated, internally field-excited (IR/IF) Delco 11SI design standard, this alternator delivers a robust 150-amp output at 12 volts, with clockwise rotation and a groove pulley configuration. Being supplied brand new rather than remanufactured means there are no worn brushes, degraded diode packs, or unknown service history to factor into your rebuild planning.
The unit is verified against 17 machine applications across the Case and New Holland Industrial ranges, including the Case 420CT, 430, 435, 440, 440CT, 445, 445CT, and 450 (model years 2004–2012). Use the vehicle selection tool or search by OEM number to confirm fit against your specific machine and engine variant.
