General

This TASK gives the procedure for repair by replacement of the rear attrition linings. Attrition lining panel sections can be replaced individually. Partial replacement of a panel section by the cutting is not permitted. If an area of a panel section is damaged beyond limits then the whole section must be replaced.

Throughout this repair cleanliness must be maintained. Dirt or grease on bonding surfaces will result in poor adhesion and unsatisfactory bonds. Clean cotton or polythene gloves must be worn by all personnel handling parts to be bonded. Handling must be kept to a minimum and components must not be handled on prepared surfaces.

Adhesive curing is accomplished at ambient temperature or above using mechanical clamping or a vacuum bag to secure the replacement linings.

To get good bonding, care must be taken on preparing properly abraded surfaces and proper use of adhesive.
