Product Number: 12653N
The WAI 12653N is a brand-new 12V 35A alternator. It is engineered to replace Denso original-equipment units, including references 101211-1240 and 101211-1242, across a range of compact plant machinery. Built to the Denso IR/IF design specification with an internal regulator and internal fan, it is a direct-fit replacement for six John Deere ZTS compact excavator models — covering the 27C ZTS, 27ZTS, 35C ZTS, 35ZTS, 50 ZTS and 50C ZTS — restoring reliable charging performance without modification.
The unit features a groove pulley and conforms to the Denso IR/IF architecture, meaning the voltage regulator is integrated within the alternator housing rather than mounted externally. This design simplifies installation and reduces the number of external components that can fail. Cross-references on file include Denso 101211-1240, Denso 101211-1242, Delco Remy DRA1345, Isuzu 8970489681, Isuzu 8972251170, John Deere AT195649, John Deere AT254905 and Universal UNA2561, among others — eleven OE references in total, making it straightforward to verify against your existing part number.
Supplied brand new, the 12653N offers a cost-effective, specification-matched alternative to dealer-sourced alternators for John Deere ZTS excavator operators and workshop technicians.

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...

A. The WAI 12653N is a brand-new 12V, 35A alternator built to the Denso IR/IF design — meaning it incorporates an internal regulator and internal fan. It is fitted with a groove pulley. These specifications make it a direct replacement for the Denso OE units listed against John Deere ZTS excavators.
A. IR/IF stands for Internal Regulator / Internal Fan. The voltage regulator is built into the alternator body rather than mounted separately on the machine, and the cooling fan is housed inside the unit. This is the standard Denso architecture for the original-equipment alternators fitted to the John Deere ZTS excavator range this part replaces.
