1. Loosen the exhaust pipe elbow and bellows.
2. Grind down the upper edge of the exhaust pipe so that it becomes even.
3. Check that sleeve can be installed all the way down on the upper edge of the exhaust pipe. In certain cases, a notch must be made in the sleeve so that it can be installed all the way down against the upper edge.
4. Clean the oxide off the surface of the exhaust pipe. Roughen the surface with a coarse emery cloth both inside and out. Wash the sleeve and the exhaust pipe with oil-free acetone.
5. Coat the inside of the sleeve and the exhaust pipe with lengths of silicone. Press the sleeve onto the exhaust pipe with a rotating motion.
6. Allow the silicone to dry for around 4 hours. To facilitate installing the bellows, the sleeve should be coated with soapy water before the bellows is installed. Kit 3851115 includes 4 pcs hose clamps; use them during installation. Install the exhaust pipe elbow.
