Installation Notes and Tips

Confirm the transmission application and position before installation, especially on Corolla and Matrix models that use left or right side fitment. Inspect the shaft surface, seal bore, and surrounding components for wear or damage before pressing in Timken 320603. Clean the sealing surface thoroughly so the ribbed inner diameter can seat properly and maintain a consistent seal.

Quality Assurance

Timken designs oil and grease seals with reinforced construction and contamination control features to support reliable sealing performance in drivetrain service. This part cross-references National 320603 for the same application.
