Timken 320564 Automatic Transmission Torque Converter Seal - Front

Timken 320564 Torque Converter Seal

The Timken 320564 automatic transmission torque converter seal is built for front-position applications on select Toyota vehicles from 1965-1980. It uses a V-fluoro-elastomer sealing material and a reinforced outer case to help maintain a secure seal at the transmission interface.

• V-fluoro-elastomer construction for sealing performance in transmission service
• Reinforced outer case helps resist installation damage
• Ribbed rubber inner diameter helps seal minor spindle imperfections and improve seating
• Internal contamination exclusion system helps block debris that can lead to leakage
• Vent holes promote lubricant flow around the seal lip to reduce heat build-up
• Clockwise helix type, Seal Type 32, with 2.688 in. outside diameter, 1.772 in. shaft diameter, and 0.472 in. width

Detailed Application Coverage

Compatible With Toyota Pickup front applications from 1970-1980, Toyota Celica front applications from 1972-1979, Toyota Corona front applications from 1969-1979, Toyota Cressida front applications from 1978-1979, and Toyota Land Cruiser front applications from 1965-1979. It also covers Toyota Celica, Corolla, and Corona front/N/A listings shown in the fitment data for select years. This Timken 320564 seal is a direct-fit service part for restoring transmission sealing at the torque converter area on these Toyota platforms.

This part cross-references Dynomax 17758 and Remy 17767 for the same application.

What This Seal Helps Address

• Transmission fluid leakage at the torque converter seal area
• Contamination entering the transmission through a worn seal
• Seal damage caused during installation
• Poor sealing on shafts with minor surface imperfections
• Heat-related seal wear from restricted lubricant flow

Installation Notes and Tips

Inspect the shaft and housing bore before installation to confirm the sealing surfaces are clean and within specification. The reinforced case and ribbed inner diameter are designed to support proper seating, but the seal should still be installed squarely to avoid distortion. Verify the clockwise helix orientation and confirm the listed dimensions match the transmission service requirements before assembly.

Quality Assurance

Timken oil and grease seals are engineered with precision sealing designs to help prevent lubricant escape and keep contaminants out of the assembly. The 320564 follows Timken’s sealing design approach for durable transmission service in Toyota front applications.
