239897 - Miller 13-Inch 6-Blade Pusher Fan for Bobcat and Trailblazer Diesel Welders

Reliable Engine Cooling for Miller Diesel Welders

The Miller 239897 Engine Cooling Fan is a critical replacement component designed to maintain optimal operating temperatures for your heavy-duty industrial welding equipment. Specifically engineered for the Bobcat™ 250 Diesel and Trailblazer® 325 Diesel engine-driven welder/generators, this fan ensures your machine runs efficiently even during long duty cycles in hot environments. Overheating is a primary cause of engine failure and downtime; replacing a damaged or worn fan blade is a cost-effective maintenance step that protects your valuable investment.

This genuine Miller Electric part features a 13-inch diameter with a 6-blade pusher design. The "pusher" configuration is essential for the specific airflow dynamics required by these diesel units, forcing cool air through the radiator to dissipate heat effectively. Unlike generic universal fans, this OEM part guarantees the correct pitch, bore size, and balance, eliminating vibration that could damage water pumps or bearings. With a shipping weight of just over 1 lb, it is a lightweight yet durable solution constructed to withstand the rigors of job site use.

Genuine OEM Quality

When it comes to engine components, fitment is everything. The Miller 239897 is manufactured to the exact specifications of the original equipment. This ensures that the fan sits perfectly within the shroud, maximizing static pressure and airflow. Using non-OEM fans can lead to insufficient cooling, increased noise, or physical interference with hoses and belts. Trusting genuine Miller parts means trusting the engineering that built your welder.

Signs You Need a Replacement

Inspect your cooling fan regularly. Cracks in the plastic blades, chipped edges from debris, or excessive wobbling are clear indicators that replacement is needed. A compromised fan not only reduces cooling efficiency but can also shatter under high RPMs, causing extensive damage to the radiator and surrounding components. Keeping a spare Miller 239897 on hand is a smart strategy for fleet managers and independent welders alike to minimize unexpected downtime.
