Leak Test

If welds on the torque converter indicate leakage, remove the torque converter and make the following check:
1. Clean the outer surface of the torque converter.





2. Install the Rotunda Check Tool and Gasket 014-R1075 or equivalent into the torque converter hub.





3. Install the torque converter into a press with flywheel studs facing up.
4. Apply enough pressure from the press to seal the tool into the hub of the torque converter.





5. Connect air hose to the tool, apply maximum 80 psi.





6. With air pressure applied to the torque converter, inspect for leaks at the seams, studs and pilot hub. A soapy water solution may be used in these areas to aid in diagnosis. If leaks are present in these areas, replacement of the torque converter is necessary.





7. Remove air hose and release air pressure from tool by pulling on release valve ring.





8. Release pressure from the press, and rotate the torque converter so the tool is facing up. Apply pressure from the press to seal the tool into the torque converter.





9. Connect air hose to the tool, apply maximum 80 psi.
10. With air pressure applied to the torque converter inspect for leaks at the seams and impeller hub. A soapy water solution may be used in these areas to aid in diagnosis. If leaks are present in these areas, replacement of the torque converter is necessary.





11. Remove air hose and release air pressure from tool by pulling on release valve ring.
