Fig. 18. Torque packing nut (202) down onto adjust-
ment spacer (228) 140 +/--10 in-lb (15.82 +/-- 1.13
N•m).
Remove throat adjustment spacer (228) when pump
packings begin to leak after much use. Then tighten
packing nut down until leakage stops or lessens. This
allows approximately 100 gallons of additional opera-
tion before a repacking is required.
