We have recently been receiving from Borg & Beck clutch driven plates of which the rivets have not been countersunk sufficiently deeply to accomodate reasonable wear of the facings. Borg & Beck have agreed that in the future the depth of the rivet head below the surface should be .040 ± 5, and plates should be inspected for this dimension.
