Revive Your Diesel Welder

When your trusty engine-driven welder gives up the ghost, you need a serious solution to get back to work. The Miller 258073 is the factory-original replacement Kubota D722 diesel engine for your Miller equipment.

Whether you are running a Bobcat or a Trailblazer diesel, this engine is designed to drop right in and bolt up without headaches.

The Kubota D722 is legendary in the welding world for a reason. It sips fuel, runs quiet, and lasts for thousands of hours with proper maintenance. This 3-cylinder diesel beast provides the steady RPMs needed to produce the smooth welding arc you rely on. It handles the sudden load spikes of striking an arc or running a grinder off the generator power without bogging down. This replacement unit comes as a complete block assembly, ready to be dressed with your machine's specific external components.

Investing in a new OEM engine is often more cost-effective than buying a whole new welder. It breathes new life into your existing rig, giving you another decade of service life. This engine features liquid cooling to handle hot summer days on the job site and robust internal components designed for the rigors of mobile welding. Get your rig back in the field and making money with the reliability of a brand-new Kubota diesel heart.
