Procedure to Install Torque Converter Lip Seal
Transmission assembly must be completed up to the torque converter housing in order to use the input shaft as a pilot for the lip seal installation. Refer to Disassembly and Assembly, KENR5091 for the correct procedure.
Use Tooling (A) to install 363-2112 Lip Type Seal (1) .
Inspect Tooling (A) to ensure that the seal installation tool is in good condition and free of defects (rust, nicks, dings, contamination and so on). Wipe the seal installation tool clean and make sure that the seal installation tool has been dried completely and is free of oil.Note: Cleanliness is an important factor. Before assembly, thoroughly clean tools in cleaning fluid. Allow the tools to air dry. Wiping cloths or rags should not be used to dry parts. Lint may be deposited on the parts which may cause later trouble. Inspect all parts. If any parts are worn or damaged, use new parts for replacement.
