Detailed Description

Timken 222743 is an engine camshaft seal designed around precision sealing geometry to keep lubricant where it belongs and help prevent contaminants from entering the engine. The seal’s reinforced outer case adds support during installation, while the ribbed rubber inner diameter helps create a positive seal against minor shaft imperfections. Its vented design allows lubricant circulation around the seal lip, which helps manage heat at the sealing surface. This makes it a practical choice for Acura Integra front camshaft seal replacement, Honda CR-V front camshaft seal service, and other listed applications.

This part cross-references National 222743 for the same application.

What It Helps Address

• Oil seepage at the camshaft seal area
• Contamination entering the engine through a worn seal
• Heat-related seal wear at the lip surface
• Improper sealing from minor shaft surface imperfections
• Damage during seal installation on the housing edge

Installation Notes and Tips

Verify shaft diameter, housing bore, width, and helix direction before installation. Clean the sealing surface thoroughly and inspect the camshaft for wear, scoring, or burrs that could affect sealing. Install the seal squarely to avoid distortion of the outer case or sealing lip. Confirm the vehicle application by year, make, model, and position before service.
