CAUTION
Never reuse an old stem (key 7) with a new valve plug. Using an old stem with a new plug requires drilling a new pin hole in
the stem. This weakens the stem and may cause it to fail in service. However, a used valve plug may be reused with a new
stem.
4. To replace the valve stem (key 7), drill out the pin (key 8) and unscrew the stem from the valve plug.
