VHA engineering staff posted a major revision to the CSS-500-WC-6TG-10 Bearing Installation guide in March 2019. Revision D of this customer support specification includes revised procedures for the removal, installation, and inspection of the WC-6TG-10 bearings used in VHA’s 206 tail rotor blades.
The new field installation procedures allow the bearings to be installed from either side of the blade; Rev C specified the WC-6TG-10 bearings be installed from the top side only. The removal instructions have also been revised in Rev. D to account for the bearing being installed from either side.
