To be accomplished not later than the first engine change after March 1, 1948, but in any event not later than June 1, 1948.
To prevent failure in the engine supercharger control actuator when shifting from low to high blower and vice versa, it is necessary to provide overtravel in the engine supercharger control linkage by installing a new Geneva-Loc supercharger actuator lever, a new Bendix link-supercharger actuating link and a new four-hole mounting support bracket.
