Detailed Description

This Timken manual transmission shift shaft seal is engineered to retain lubricant at the shift shaft while keeping contaminants out of the transmission housing. The seal’s precision design, reinforced case, and ribbed sealing surface support consistent seating on the shaft, while vent holes help circulate lubricant around the lip to manage heat.

This part cross-references AMS Automotive 6426 and SKF 6913 for the same application.

What It Helps Address

• Transmission oil seepage at the shift shaft
• Grease or lubricant loss from the seal area
• Contamination entering the manual transmission housing
• Seal wear caused by minor shaft surface imperfections
• Heat-related seal deterioration around the lip area

Installation Notes and Tips

Verify shaft diameter, housing bore, and width before installation to confirm proper fitment. Clean the bore and shaft surface thoroughly, and inspect for scoring or burrs that could affect sealing. Press the seal in evenly to avoid case distortion and ensure the lip seats squarely on the shaft.
