286616 - Miller 286616 Replacement Kohler CH730 Engine with E-Choke

Genuine Miller Replacement Engine: Kohler Command PRO CH730-3338

The Miller 286616 is a complete replacement engine assembly featuring the Kohler Command PRO CH730-3338, specifically configured for Miller Electric industrial welder generators. This unit is an OEM (Original Equipment Manufacturer) component, ensuring seamless integration with compatible Miller equipment such as Bobcat and Trailblazer series machines. The CH730 is a horizontal-shaft, V-twin, air-cooled gasoline engine designed to deliver consistent power and torque required for the demanding load cycles of welding and power generation.

A standout feature of this model is the integrated E-Choke™ technology. This system automatically manages the choke function during starting, eliminating the need for manual choke adjustments and ensuring reliable ignition in various temperature conditions. This is particularly critical in industrial environments where equipment must perform immediately upon demand. The engine block features cast iron cylinder liners, which provide superior wear resistance and longevity compared to aluminum-only designs.

Maintenance and durability are core to the Command PRO series. The engine utilizes hydraulic valve lifters, which negate the need for periodic valve lash adjustments, reducing downtime and maintenance costs. A full-pressure lubrication system with a spin-on oil filter ensures critical components are continuously protected, even during continuous operation. The large-capacity air intake system is engineered to filter out heavy particulate matter common in construction and fabrication sites, preventing premature engine wear.
