Product Number: 12270N
The WAI 12270N is a brand-new 12V 40A alternator. It is built to Denso IR/IF specification, replacing original-equipment units from Denso (including 100211-4440 and 101211-1310) and Bosch (0986037271) across seven Massey Ferguson compact tractor models from the 1990s and early 2000s. It is a direct-fit solution for buyers sourcing a dependable replacement without resorting to a reconditioned unit.
Constructed to IR/IF (internal regulator, internally fan-cooled) design, the 12270N delivers a rated 40-amp output and is fitted with a groove pulley to match the original drive configuration. Being brand new rather than exchange or remanufactured, there is no core return requirement and no uncertainty over the condition of internal components such as the rectifier, regulator, or windings.
The unit covers all seven Massey Ferguson applications in the fitment data, including the MF-1205, MF-1210, MF-1215, MF-1225, MF-1240, MF-1250, and MF-1260 — compact utility tractors produced between 1992 and 2000. Fifteen OE and aftermarket cross-references are catalogued for this part, spanning Denso, Bosch, Iseki, Hella, DRI, Farcom, and Unipoint.

Exploring the WAI Starter Motor and Alternator at Partsformachines.com Introduction: In the Plant and Agriculture sector, a starter motor and alternator are parts that ensure a machine runs smoothly. At Partsformachines.com we have partnered with WAI, a global manufacturer of auto and plant machinery parts to off...
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...
