There is not ample room in this stuffing box area, and to negate this practice, would lead to running out of room for the entire packing set.

Proper packing configuration is extremely important to allow seal water to cool shaft.

MT DATE CAUTION:
Monitor the stuffing boxes temperature to determine if seal water is keeping the shaft cool. Scoring of the shaft will occur is excessive temperatures of the stuffing boxes are reached, resulting from the packing being of the improper configuration or over-tightening.
This type packing is not meant to be leak tight. A small amount of leakage is needed at al times to lubricate and cool the packing. If adjustment is required, be sure that all packing gland nuts are tightened evenly and gradually.

HOUSE KEEPING 12.
13.
Monitor stuffing box temperatures, I.B. and O.B. and adjust packing by taking a flat at a time and evenly across the two gland nuts, until the desired packing leakage is achieved.
-t Remove all debris, tools, and materials from the area. Ensure all work areas meet PBNP housekeeping expectations.
