Product Number: 7331N
The WAI 7331N is a brand-new 24V 22A alternator. It is built to Prestolite ANB Series IR/IF specification, designed to replace original-equipment units across a broad range of Caterpillar agricultural and industrial machinery and Case construction equipment. It cross-references directly against Delco Remy DRZ0118, Remy 53013, Prestolite 51-153 and 51-153A, Caterpillar 2P1204, 2P1698 and 2P5113, and Case A34730, A44440 and A44794, among 33 verified OE references in total — making it a confident like-for-like replacement wherever the original Prestolite ANB unit was fitted.
Supplied without pulley, the 7331N fits the existing drive arrangement on the target machines without modification, using the vehicle's existing pulley assembly. The internal regulator/internal field (IR/IF) design eliminates the need for an external voltage regulator, keeping the installation straightforward and reducing the number of additional components required on older plant and agricultural platforms.
With 73 confirmed applications across Caterpillar Ag. & Ind. models — including the 112F, 120, 120B, 120G, 12F and 12G graders — and 2 Case applications covering the 1150B dozer and 1450 loader, the 7331N addresses a wide service base of classic heavy plant built predominantly from the late 1960s through the late 1970s.
