Drop Box Shaft Seal for Ford New Holland 40 Series 4WD and Early TS Series Tractors

Description

If you’ve been finding puddles of gear oil under your 4WD tractor, there’s a good chance this little seal is the culprit. The precision-engineered seal prevents costly oil leakage from the front drive axle drop box, maintaining proper lubrication levels that extend component life and ensure reliable 4WD operation. When that front drive is working overtime in muddy fields or on steep ground, the last thing you need is a leaky drop box leaving your gears running dry.

What You’re Getting

• Exact 35x50x10mm dimensions for perfect fit in your drop box assembly
• High-quality seal material withstands the harsh operating environment of agricultural applications, including exposure to dirt, moisture, and temperature variations
• Proper sealing prevents contamination that could cause premature wear of expensive drive components while maintaining optimal lubrication for smooth, efficient power transfer to the front wheels
• Direct replacement—no modifications or special tools required

Built for Real Farm Work

This drop box seal is essential for Ford New Holland 4WD tractors used in demanding agricultural operations where front wheel drive engagement is critical for traction and productivity. The 40 series and early TS series tractors are commonly employed for heavy tillage work, muddy field conditions, steep terrain operations, and loader applications where maximum traction is required. Whether you’re pulling a chisel plow through tough ground or maneuvering a loader in tight spots, these tractors earn their keep by putting power to all four wheels.

Made to Last

This seal is built to handle the constant rotation and pressure changes that come with real farm work. The seal material stays flexible through temperature swings while resisting the chemicals in modern gear oils. It’s designed to keep doing its job season after season, even when your tractor’s working in less-than-ideal conditions.

Good to Know

Verify your tractor model and drop box configuration before ordering, as later TS series models require seal part number 4907. During installation, ensure the seal housing is clean and free of debris, and install the seal with proper orientation to prevent leakage. Use appropriate installation tools to avoid seal damage and follow manufacturer torque specifications for reassembly. While you’ve got the drop box open, it’s a good time to check your gear oil level and condition too.
