Fig. 20. Torque seal and packing nut (202) down onto throat adjustment spacer (228) to 100 +/--10 in-lb (75 +/--5 in-lb for 246257) (140+/--10 in--lb for 287814, 287815).

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.
