Miller Fan Spacer for Kubota D902 Diesel Engine

Keep Your Engine-Drive Running Cool

Your engine-driven welder is the heart of your mobile operation, and keeping that diesel engine cool is vital for all-day performance. The Miller 258335 Fan Spacer is the genuine replacement part you need if you are repairing the cooling system on your Kubota D902-equipped machine. Over time, during maintenance or repairs, small components like spacers can be misplaced or damaged. Installing the fan without the correct spacer—or with the wrong one—can result in poor airflow, causing your machine to overheat right when you are in the middle of a critical job.

This spacer is designed specifically to fit the Kubota D902 engine used in popular Miller welders. It pushes the fan out to the correct distance from the engine, ensuring the blades pull enough air through the radiator to keep temperatures down. It fits perfectly without modification, making your repair job smoother and faster. Don't take chances with aftermarket parts that might not line up correctly; a wobbling fan can destroy your water pump or radiator.

Trust in genuine Miller parts to maintain the reliability of your equipment. This spacer is built to handle the vibration and heat of a job site environment. By restoring your cooling system to factory specifications, you protect your engine's longevity and ensure consistent welding output without thermal shutdowns.
