Description
When your Massey Ferguson 300 series alternator starts running hot or you notice the battery isn’t holding a charge like it should, that little cooling fan behind the alternator might be the culprit. The alternator works hand-in-hand with the cooling fan to keep electrical output steady and prevent overheating, especially during those long summer days when you’re running lights, air conditioning, or hydraulic systems. This replacement fan gets air moving across the alternator windings where it needs to be.
What You’re Getting
- Heavy-duty construction that handles the constant duty cycle and harsh conditions of farm equipment
- Precision-balanced blades that move maximum air with minimal vibration
- Direct replacement design that bolts right onto your existing alternator
- Temperature-resistant materials that maintain performance through seasonal extremes while preventing belt slippage
Built for Real Farm Work
The Massey Ferguson 300 series tractors are versatile utility machines designed for diverse agricultural operations including crop cultivation, livestock farming, and general farm maintenance with their robust Perkins diesel engines. Whether you’re running a 365, 375, 390, or 399, these tractors work hard in demanding conditions where reliable electrical systems matter.
Made to Last
This cooling fan features heavy-duty bearings rated for agricultural use and sealed against dust and moisture. Farm equipment takes abuse from vibration, temperature swings, and debris, but this fan keeps your alternator cool and charging properly season after season.
Good to Know
Installation is straightforward – just unbolt the old fan and mount the new one using the existing hardware. Before you start, make sure your alternator belt is in good shape and properly tensioned, as a slipping belt can cause alternator overheating. While you’re at it, clean any debris from around the alternator housing to help airflow.
