Industrial 1319N Alternator

The Bosch 1319N alternator is a belt-driven charging system component designed to convert engine power into electrical energy for charging the battery and running the tractor’s onboard electrical systems. This 12 VDC unit uses an internal electronic regulator and internal fan cooling, features clockwise rotation, a V-Belt pulley, and a saddle/ear mounting style for straightforward installation. It is commonly installed in John Deere 1020, 1030, 1040, 1133, and 1530 tractors equipped with Bosch charging systems, supplying power to the battery, lighting, gauges, and accessories while the engine runs. As a Bosch aftermarket equivalent, the 1319N is used for charging-system repairs, replacement of failed alternators, preventive maintenance, and restoration of vintage farm equipment; common replacements include Bosch AL393X, John Deere AR85250, and Bosch 0 120 489 747.
