    A005T75

    Note

    • Repair the seat while checking the seating position.

    • Keep the lip free from foreign matter.

    1. Using a 45° cutter, resurface the valve seat so that the valve seat width is more than the specification.

    2. Using 30° to 75° cutters, correct the valve seat so that the valve contacts the entire circumference of the seat. The contact should be in the center of the valve seat, and the valve seat width should be maintained within the specified range around the entire circumference of the seat.
