278028 - Miller Bobcat/Trailblazer LP Engine Maintenance Kit (Kohler PCH740)

Keep Your Miller Welder Running Like New

Don't let a dirty filter shut down your job site. The Miller 278028 Tune-Up & Filter Kit is the easiest way to protect your investment and ensure your Miller Bobcat or Trailblazer stays ready for action. Designed specifically for machines equipped with the Kohler PCH740 LP engine, this all-in-one kit takes the guesswork out of routine maintenance. Instead of hunting down individual part numbers and hoping they fit, you get everything you need in one convenient box, direct from the manufacturer.

Why is a tune-up important?
Your engine-driven welder works hard. Over time, dust, dirt, and combustion byproducts clog your filters, robbing your engine of power and potentially causing costly damage. A clogged air filter can cause the engine to run rich and lose power, while dirty oil accelerates wear on critical internal components. By swapping out these consumables regularly with the Miller 278028 kit, you ensure your machine starts easier, runs smoother, and lasts longer.

What's inside the box?
This kit is packed with genuine OEM quality parts, including a heavy-duty oil filter, a specialized LP gas fuel filter, and a two-stage air filtration system (filter plus pre-cleaner) to handle the dustiest construction sites. It also includes the correct spark plug to keep your firing order precise. Whether you are a professional welder relying on your rig for your livelihood or a fleet manager responsible for multiple machines, this tune-up kit is a smart, cost-effective way to prevent downtime and keep your Miller equipment performing at its peak.
