Refer to Figure.
NOTE
If it is necessary to replace the abradable seal rubber on the inner ring, remove the rubber after the vanes have been removed. The new rubber should be put back and cured after the new vanes have been attached and bonded.Refer to VRS1437 (TASK 72-32-91-300-008) (REPAIR-008).NOTE
If it is not necessary to repair the rubber, put on a shield to prevent damage to the rubber during this repair.Remove the remaining molding rubber from the removed vane if the vane is serviceable.
SUBTASK 72-32-91-350-063 Remove the Damaged Vane
Refer to Figure.
SUBTASK 72-32-91-120-055 Abrasive Blast for the Bonding Area
Refer to Figure.
SUBTASK 72-32-91-110-060 Clean the Blasted Area
Refer to Figure.
The primer must be applied to the metal surface only.
Refer to the SPM TASK 70-36-04-360-501.
Use CoMat 08-032 PRIMER.

CAUTION
THE PRIMER MUST NOT BE APPLIED TO THE SILICONE RUBBER.NOTE
Let the primer dry at a room temperature of 77 deg F (25 deg C) for 2 hours minimum, 24 hours maximum at a moisture level equivalent to 50 percent minimum relative humidity.NOTE
Parts must have the silicone rubber compound applied within 24 hours of completion of primer application.Apply the primer to the bonding area.
SUBTASK 72-32-91-360-073 Apply the Primer to the Bonding Area
Use CoMat 08-042 SILICONE RUBBER COMPOUND, a clean spatula and a mass weighing scale.
