Clutch liner removal made easy Converter clutch liner removal can be time consuming and sometimes a health and ecological concern. At best it may involve hazardous chemicals used to chemically strip the adhesive that bonds the clutch liner to the steel piston or converter cover. The other more common practice is machining on an engine lathe to cut both liner and steel away for surface preparation. Both require disposal of consumed chemicals and/or machine tooling such as carbide inserts, sandpaper, wire wheels and more.
Let’s look at a very effective way to remove these clutch liners without conventional machining or use of harsh chemicals. Water jet machining is not new. It has been used in industry for more than 20 years. Midwest Converters, Inc. of Rockford, IL, would like to share its information and success with a very specialized process to remove clutch liners using water jet technology.
Find yourself a used 40,000 PSI low water flow water jet metal cutting machine. Shop around and make sure it is a low water flow machine. Low flow high pressure will lessen deflection than a high flow lower pressure machine. You do not need a CNC version to accomplish speedy and perfect results. A manually operated machine with a fixed jet arm can be used. Simply install a power rotating indexing table or an equivalent fixture to rotate the clutch piston with a variable speed control. Mount the water jet above the rotating piston. Around 60 seconds is all that is required to remove the clutch liner. You can control rotation speed and jet pressure to “peel” the liner off cleanly. No chemicals or environmental concerns. Even an unskilled laborer can remove 30 to 50 liners an hour.
The water jet will not affect the metal if used with a small degree of caution and an hour of practice. This will make rebuilding converters a little more efficient and even help save the environment.
