The Miller 206421 Tune-Up and Filter Kit is an essential maintenance package designed specifically for Miller engine-driven welders equipped with the Kubota D722FB-25 diesel engine. Regular maintenance is the key to longevity for industrial equipment, and this kit simplifies the process by gathering all the necessary filtration components into one convenient box. Whether you are operating a Bobcat 250 Diesel or a Trailblazer series machine, this kit ensures your power source remains reliable, efficient, and ready for the toughest jobsites.

Genuine OEM Quality

Using genuine Miller and Kubota parts is critical for maintaining the factory performance of your equipment. The 206421 kit includes OEM filters that are engineered to meet the precise flow rates and filtration specifications of the D722FB-25 engine. Aftermarket filters may not provide the same level of protection against dust, debris, and fuel contaminants, which can lead to costly engine repairs down the line. By choosing this genuine kit, you are investing in the long-term health of your welder.

What's Inside the Box?

This comprehensive kit covers the primary fluid and air circuits of your diesel engine. It includes:

• Oil Filter (187443): Captures metal shavings and carbon deposits to keep your engine oil clean and lubricating effectively.
• Air Filter (187441): A high-efficiency filter designed to trap airborne particulates common in welding and construction environments, preventing cylinder wear.
• Fuel Filters (187442 & 213858): Two distinct filters to ensure that only clean, water-free diesel reaches your injectors, maintaining optimal combustion and power output.

Maximize Uptime

Downtime on a jobsite costs money. By keeping a Miller 206421 Tune-Up Kit on hand or in your maintenance truck, you can perform scheduled services quickly and efficiently without waiting for individual parts to arrive. This kit is tailored for the specific needs of the Bobcat 250 D NT, Bobcat 250 Diesel, and the Trailblazer 300/301/302 D series, making it a versatile solution for fleets running multiple Miller diesel machines.
