Detailed Description

FAG SS4672 is engineered as a rear engine crankshaft seal for vehicles that require a tightly controlled sealing interface. The Viton sealing material is selected for durability in engine environments, while the spring-loaded rubber design and auxiliary lip help maintain sealing contact at the crankshaft. With its specified bore, outside diameter, and width, this seal is intended to match the application dimensions used on listed Ford and Lincoln models. This part cross-references National 710896 for the same application.

What This Part Helps Address

• Oil leakage at the rear crankshaft seal area
• Contamination entering the sealed engine interface
• Loss of sealing contact from worn or hardened seal material
• Fitment issues caused by incorrect seal dimensions
• Service replacement needs on rear-seal Ford and Lincoln applications

Installation Notes and Tips

Verify the vehicle year, make, model, and rear-position application before installation. Match the seal dimensions to the original part and inspect the crankshaft sealing surface for wear, scoring, or contamination before fitting the new seal. Clean the housing thoroughly and install the seal squarely to avoid distortion of the sealing lip.

Quality Assurance

FAG designs seals to meet vehicle manufacturer specifications and works with suppliers to maintain its quality standards. The seal is built to protect the wheel-end style sealing interface from dirt, dust, and moisture intrusion while helping retain grease or oil at the bearing or crankshaft area over the service life of the component.
