If the existing valve plug is reused and the adaptor is in good condition it may be reused also However never reuse an old adaptor with a new valve plug Using an old adaptor with a new valve plug requires drilling a new pin hole in the adaptor This drilling weakens the adaptor and may cause failure in service However a used valve plug may be reused with a new adaptor 3 Inspect the existing valve plug and adaptor If they are in good condition they can be reused with the new stem bellows assembly and they do not need to be separated CAUTION When removing installing a valve plug on the ENVIRO SEAL stem bellows assembly the valve stem must not be rotated Damage to the bellows may result Do not grip the bellows shroud or other parts of the stem bellows assembly Grip only the flat areas on the stem where it extends out of the top of the bellows shroud Note The ENVIRO SEAL stem bellows assembly has a one piece stem 4 If the valve plug and adaptor are not in good condition and must be replaced the valve plug adaptor assembly must first be removed from the stem bellows assembly and then the valve plug removed from the adaptor First place the stem bellows assembly and valve plug in a soft jaw chuck or other type of vise so that the jaws grip a portion of the valve plug that is not a seating surface Drive out or drill out the pin key 8 Drive out the pin key 36 figure 21 Then reverse the stem bellows and plug adaptor assem
