Detailed Description

FAG SS5025 is an engine crankshaft seal engineered around exact fit dimensions and a Viton sealing element to help maintain a stable seal at the crankshaft. The rubber spring auxiliary-lip construction supports consistent contact at the sealing surface, while the listed bore, outside diameter, and width help confirm application match during engine repair or rebuild work. This part number, SS5025, is a practical choice when replacing a worn crankshaft seal on vehicles such as Honda Civic and Toyota Corolla applications that require this specific size and seal profile.

This part cross-references National 712449 and SKF 48046 for the same application.

What It Helps Fix

• Engine oil leaking from the crankshaft seal area
• Oil residue collecting near the front or rear of the engine seal location
• Seal wear caused by age, heat, and crankshaft movement
• Contamination entering the sealed engine interface
• Loss of sealing integrity during engine service or rebuild

Installation Notes and Tips

Verify bore diameter, outside diameter, and seal width before installation to confirm SS5025 matches the engine application. Inspect the crankshaft sealing surface for scoring, grooves, or contamination before pressing in the new seal. Clean the housing thoroughly and install the seal squarely to avoid distortion of the auxiliary lip or spring-loaded sealing edge. Use the vehicle service procedure for the correct installation depth and orientation.

Quality Assurance

FAG sources sealing components to meet vehicle manufacturer specifications and works with suppliers to maintain its quality standards. The Viton sealing material and multi-lip design support demanding engine sealing requirements where dimensional accuracy and material compatibility matter.
