Product Number: 12189N
The WAI 12189N is a brand-new 12V 40A alternator. It is built to Denso IR/IF specification, replacing original-equipment Denso, Bosch, and Delco Remy units across a range of compact agricultural and industrial machines. With 104 verified OE cross-references, it is a well-catalogued replacement for anyone working on Ford, Kubota, Massey Ferguson, New Holland Industrial, Agco, Thermo King, and Ishikawajima equipment.
The unit features an internally regulated, internally field-excited (IR/IF) design, clockwise rotation, and a groove pulley — characteristics that must match the original unit before fitting. At 40 amperes output, it suits the modest electrical loads typical of compact utility tractors and small industrial engines.
Fitment spans nine confirmed applications including the Ford 1220 (1995–1999), Kubota Various (1986–2007), Massey Ferguson MF-1220 (1993–1999), New Holland Industrial 1220 and TC21D/TC24D, Agco ST45, and Thermo King units. Cross-references include Denso numbers such as 021080-0760, 100211-1610, and 100211-1611, Bosch Exchange numbers 0986037270, 0986037271, and 0986603727, and Delco Remy DRA7271, among 104 references in total.
Supplied brand new.

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.
