      2. Mask the areas of the cover not to be plated.

      3. Do the nickel plating.

      2. Plate to a sufficient thickness to permit the machining to the last dimensions.

      3. Plating not in the piloting diameter area is permitted but must be removed.

    4. Remove the mask.

      5. Clean and dry the cover.

      1. Flush with cold water.

      2. Flush with hot water.
