Description
That puddle of oil under your tractor isn’t just a nuisance—it’s your engine warning you about a failing crankshaft seal. When this critical seal starts letting oil seep out, you’re looking at more than just messy shop floors. You’re not just losing oil—you’re looking at potential bearing damage and costly repairs down the road. Whether you’re running a Fiat G240 through tough tillage work or pushing your 8970 through long harvest days, keeping this seal tight is what protects that expensive engine.
What You’re Getting
- Precise 66.7 x 89 x 24.8mm dimensions that fit exactly like the original seal
- Heavy-duty materials built to handle the heat, pressure, and vibration these big engines dish out
- Quality construction that maintains its seal even after thousands of hours of crankshaft rotation
- Direct replacement part that works on both Fiat G-series and Ford New Holland 70-series tractors
Built for Heavy-Duty Work
These aren’t your everyday farm tractors—the Fiat G170 through G240 and Ford New Holland 8670 through 8970 series are serious horsepower machines designed for the biggest jobs on the farm. From pulling wide tillage equipment across hundreds of acres to powering through harvest season with heavy grain carts, these engines work hard and run hot. Agricultural engines face unique challenges that automotive seals simply can’t handle—constant vibration from field work, thermal cycling from varying loads, and exposure to dust, moisture, and chemicals.
Made to Last
This seal uses materials specifically designed for agricultural conditions. It stays flexible in cold weather and resistant to breakdown from hot engine oil and hydraulic fluid exposure. The construction handles the constant expansion and contraction that comes with these big engines heating up and cooling down, day after day, season after season.
Installation Notes
This is definitely a job for someone with experience—replacing a rear crankshaft seal means splitting the tractor and removing major components like the transmission and flywheel. Plan for significant downtime and make sure you have the right tools for the job. Always clean the seal bore thoroughly and check the shaft for wear or damage before installing the new seal.
