9. Install each ring of packing by inserting it into the stuffing
box and, using the packing gland, pushing it in as far as
the packing gland will allow.
10. Stagger all ring joints 90°, at a minimum.
11. Use a Chesterton 176 tamping tool to firmly seat each ring
in the bottom of the stuffing box.
12. Repeat steps 9 through 11 until all rings are installed or
stuffing box is filled.
13. Install packing gland and gland follower; tighten gland bolts
to a snug load.
14. Back off on gland load and loosen gland bolts until gland
moves freely.
15. Finger-tighten bolts until gland is snug against packing.
16. Use a feeler gage to make sure that the gland is not touch-
ing the shaft (gland/shaft contact will generate excess heat
and cause equipment wear and/or damage).
17. Take-up gland nuts finger tight. Break in slowly. 100 to 200
drops per minute leakage at start, adjust (
see note
) until
leakage is approximately 20 to 60 drops per minute. Lower
leakage may be achieved depending on the application and
condition of the stuffing box.
NOTE: Adjust packing gland gradually one flat at a time, no
more than one adjustment every 15 minutes. Never permit
box to heat up. Be sure gland adjustments are applied
evenly.
