Remove the spring(s) from the valve stem.
Figure 9
– Cover Spring Removal
Remove the stem assembly from the valve body. On the underside of the stem, note
that the stem may have a flat machined surface. This flat surface is dependent on
valve size. Some valve sizes have a nut where this flat would be (Figures 10 and 11).
Secure this flat surface or the lower stem nut in a vice as shown in Figure 12.
