Product Number: 3974N
The WAI 3974N is a brand-new 12-volt starter motor. It is built to the Delco 40MT DD specification, replacing Ford and Bosch original-equipment units across a wide range of heavy plant, agricultural, and construction machines. With 225 confirmed OE cross-references — including Ford C3TZ-11001-A, Ford C5TF-11000-A, and Bosch USA SR961X — it is a well-evidenced aftermarket replacement for demanding worksites.
Constructed to the Delco 40MT direct-drive design, the 3974N runs clockwise rotation with an 11-tooth drive pinion, the geometry that the 40MT platform demands for correct mesh and reliable cranking. It is supplied brand new, not remanufactured.
This unit covers 253 applications across 26 makes, including Steiger, Hyster, Euclid, Versatile, International, Case, John Deere, Massey Ferguson, Allis Chalmers, Clark, and Terex. Machines range from heavy construction and grading equipment — Austin Western, Galion, Le Tourneau-Westinghouse, Grove Mfg. — through to large agricultural tractors and material-handling equipment.

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...
