Assembly
Visually inspect Plug/Stem & Bonnet packing box for cleanliness
and proper surface finish. Consult Figures 16 & 17 for the proper
number of packing rings and their arrangement. Assemble the
packing box parts (Packing Rings, Packing Follower/Flange,
and Packing Nuts). The skive cuts should be staggered between
consecutive pieces of Packing Rings (approx. 120 degrees). The
Packing Nuts should only be finger tight at this time.
