249784 - Miller Replacement Engine Kohler CH730 Gas with E-GOV

Genuine Miller 249784 Replacement Kohler Engine

The Miller 249784 is a complete replacement engine assembly featuring the Kohler Command PRO CH730-3267 specification. Designed specifically for Miller industrial engine-driven welders, this unit is engineered to meet the rigorous demands of field fabrication and MRO applications. The engine is a 4-cycle, V-Twin, air-cooled gasoline power plant known for its high torque output and long service life.

A defining feature of this specific spec number (3267) is the Electronic Governor (E-GOV) system. Unlike traditional mechanical governors that rely on flyweights and springs, the E-GOV uses electronic sensors and a throttle actuator to monitor and adjust engine speed. This technology allows the engine to respond near-instantaneously to the sudden load spikes characteristic of welding operations, ensuring that the generator frequency and voltage remain within tight tolerances. This is essential for protecting sensitive electronics on the welder and providing a stable arc.

This OEM part ensures seamless integration with your existing Miller equipment, matching all mounting points, wiring harnesses, and coupling interfaces. It features a full-pressure lubrication system with a spin-on oil filter, hydraulic valve lifters for maintenance-free valve trains, and a heavy-duty air filtration system designed to withstand the dust and debris of construction sites and workshops.
