What This Seal Helps Address

• Transmission fluid leakage at the torque converter seal area
• Contamination entering the seal lip and causing wear
• Heat-related seal deterioration from poor lubricant circulation
• Sealing issues caused by minor shaft surface imperfections
• Damage during installation when the old seal is removed or the new seal is pressed in

Installation Notes

Confirm shaft diameter, housing bore, and width before installation. Clean the sealing surface, inspect the converter hub and bore for wear, and install the seal squarely to avoid lip distortion. For A4LD-equipped Ford Ranger, Explorer, and Aerostar applications, verify transmission identification before ordering. Timken 2658 is also referenced by Anchor 2658 and Carlson 16119.

Quality Assurance

Timken oil and grease seals use precision sealing designs to control lubricant loss and keep contaminants out of the transmission. The reinforced case, contamination exclusion features, and vented lip design support consistent sealing performance in demanding drivetrain service.
