The water pump suitable for the MF399 tractor, often paired with the Perkins A6‑354 or AT6‑354 engine, plays a vital role in the cooling system. This component, precisely designed with a standard-sized impeller and a durable body, is responsible for the uniform circulation of the coolant. Structurally, the water pump is designed to be compatible with various pulleys, including single-belt, double-belt, or even without a pulley, providing adaptability with different tractor power transmission systems.
