What It Helps Address

• Oil leakage at the crankshaft seal area
• Contamination entering the engine sealing zone
• Loss of sealing integrity from worn or hardened seal material
• Noise or drivability concerns related to crankcase sealing issues
• Service replacement needs on high-mileage engine assemblies

Installation Notes and Tips

Verify bore diameter, seal outside diameter, and seal width before installation to confirm correct engine fitment. Inspect the crankshaft sealing surface for wear, scoring, or contamination before pressing in the new seal. Clean the housing thoroughly and install the seal squarely to avoid distortion of the lip or spring. For fitment-specific service, confirm the exact vehicle application, since SS3770 is used across multiple model years and engine platforms.

Quality Assurance

FAG seals are produced to meet vehicle manufacturer specifications using high-quality materials and application-specific engineering. The seal design is intended to protect engine components by maintaining a reliable barrier at the crankshaft sealing point. FAG SS3770 is built to the dimensional and material requirements listed above for consistent service replacement.
