Description
When the heat stops blowing or you’re getting weak airflow in your cab, there’s a good chance your blower wheel has had enough. This little fan is what moves the air through your heater and A/C system, and after years of spinning away through dusty harvest days and frozen winter mornings, the blades can crack or come loose. You’ll know it’s time for a replacement when you hear rattling from behind the dash or feel like you’re barely getting any air movement, no matter what speed you set.
What You’re Getting
- Counter-clockwise rotation design that fits your tractor’s heater system perfectly
- 4-1/4 inch diameter wheel with 3/8 inch shaft for proper fit and balance
- Durable construction that handles the constant spinning and temperature changes
- Direct replacement for your worn or damaged original wheel
Built for Real Farm Work
This blower wheel is designed to fit a wide range of International Harvester and Case tractors – from utility models like the IH 786 and 886 up through the bigger row-crop machines like the 1586 and 3688. It also works in various combine models where good cab ventilation keeps you comfortable during those long harvest days. Whether you’re running a smaller utility tractor for chores or operating a high-horsepower field machine, this wheel keeps your climate control system working like it should.
Made to Last
Farm cabs see temperature swings from below zero to over 100 degrees, plus all the dust and vibration that comes with the territory. This blower wheel is built to handle those conditions with materials that won’t crack from heat cycling or come apart from constant use. The balanced design reduces vibration and keeps things running smoothly.
Installation Notes
Getting to the blower wheel usually means removing some dash panels to access the heater housing. The wheel typically pulls off the motor shaft once you get the housing apart – just be careful not to damage the squirrel cage design. While you’re in there, it’s a good time to clean out any dust buildup and check that the motor shaft isn’t worn. The new wheel should slide on snugly and spin freely without wobbling.
