Product Number: 12337N
The WAI 12337N is a brand-new 12V 40A alternator. It is built to replace Denso original-equipment units — most notably Denso 101211-1100 and Denso OEM 1012111100 — across a wide range of Bobcat compact excavators and skid-steer machines. Supplied as a direct OE-replacement for Bobcat reference 6669618, this unit covers 29 Bobcat applications including the 319, 320, 321, 322, 322C, 322D, 323 and 324.
The 12337N follows the Denso IR/IF design — internal regulator, internally fanned — keeping the unit compact and well-protected within the machine's engine bay. Clockwise rotation and a groove pulley configuration ensure correct belt engagement without modification.
Being brand new rather than remanufactured, this alternator carries no core-return requirement and offers the full service life expected of a fresh unit. Universal cross-reference UNA143 is also listed, confirming broad sourcing pedigree.

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...
