Product Number: 12066N
The WAI 12066N is a brand-new 12V 120A alternator. It is built to the Denso IR/IF design, replacing original-equipment Denso units — including Denso 100211-6030, 100211-6031 and 100211-6050 — across 17 John Deere agricultural tractor applications. It is a direct replacement for Remy references 10459495 and 50904, and for John Deere OE numbers including RE36246, RE37201 and RE42123, making it a straightforward fit for workshops sourcing by any of those references.
The unit features a clockwise rotation and a groove pulley, matching the specification of the original Denso alternator it replaces. The IR/IF (internal regulator / internal fan) design keeps the regulator and cooling fan within the unit, which simplifies installation and ensures compatibility with the original wiring circuit without adaptation.
John Deere models covered include the 4055, 4255, 4455, 4555, 4560, 4755, 4760 and 4955, spanning model years 1989 to 1993. The full application list of 17 John Deere fitments is available via the selection widget.

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...
