        BE CARFUL NOT TO DAMAGE THE SURFACE OF VANE AND RING WHEN REMOVING MOULDING RUBBER.

        Remove molding rubber to break the connection between vane and inner ring. Remove the identified vane from the inner ring.

      1. Use a clean plastic chisel type tool.

      3. Remove rubber from Area A and Area B.

      1. Use a clean, plastic chisel type tool.

      4. NOTE

        If abradable seal silicone rubber on inner ring is to be replaced, remove rubber after vanes are removed. New rubber should be installed and cured after new vanes are installed and bonded. Refer to VRS1395 (TASK 72-32-83-300-012) (REPAIR-012). If the rubber is serviceable then it should be protected from possible damage during this repair by installing a protective shield.

        Remove remaining molding rubber from the removed vane if it is serviceable.

      1. Use a clean plastic chisel type tool.

    2. SUBTASK 72-32-83-120-051 Clean the Surfaces which are to be Applied the Silicone Rubber Compound

    1. Refer to Figure, Figure and Figure.

      2. Apply masking tape to the areas which do not require the molding compound.

    4. Remove remaining abrasive by vacuuming or clean air blow.

      5. Wipe and clean the surfaces of vane and inner ring.

      1. Refer to the SPM TASK 70-36-04-360-501.

      6. NOTE

        After cleaning the component must not be touched by hand and must be covered by craft paper to prevent contamination.
