What It Helps Address

• Oil seepage at the oil pump seal area
• Loss of sealing integrity from worn or hardened seal material
• Contamination entering the oil pump sealing interface
• Incorrect seal sizing during engine service
• Repeat repairs caused by poor-quality replacement seals

Installation Notes and Tips

Confirm shaft diameter, outside diameter, and width before installation to match the engine oil pump bore and shaft interface. Clean the sealing surfaces thoroughly and inspect the pump housing for wear, scoring, or debris that could affect seal life. Use proper installation practices to avoid damaging the nitrile sealing lip during assembly. Verify vehicle application against the Toyota Paseo and Toyota Tercel fitment listed for SKF 7918 before final installation.
