Detailed Description

SKF 19966 is a transmission sealing component used at the oil pump area to help retain automatic transmission fluid and keep external contaminants out. The seal dimensions are specified for proper fit at the pump interface, and the silicone sealing surface supports reliable contact where the seal rides on the shaft. SKF has a long history in seal engineering, and this part reflects that focus on precise design and material selection for demanding drivetrain environments. It is a direct-fit style solution for many Ford and Lincoln front transmission applications, including Ford F-150, F-250 Super Duty, F-350 Super Duty, Expedition, Excursion, Bronco, and Lincoln Navigator.

What It Helps Address

• Transmission fluid leakage at the oil pump seal area
• Fluid loss that can affect transmission operation
• Contamination entering the pump sealing interface
• Wear-related sealing issues during transmission service
• Leak concerns on Ford and Lincoln front transmission applications

Installation Notes and Tips

Confirm shaft diameter, outside diameter, and width before installation to match the transmission pump bore and shaft interface. Inspect the pump surface and shaft for scoring, burrs, or contamination before fitting the seal. Clean all sealing surfaces thoroughly and install the seal squarely to avoid distortion. Verify vehicle application by year, make, model, and front position before service.
