Packing Ring Replacement
Maintenance
• Unfasten hardware holding packing gland in place and
slide back on shaft to expose packing rings. A split
packing gland with threaded studs is shown.
• Remove packing rings from stuffing box using two
commercially available packing hooks as shown.
• Clean shaft sleeve and packing gland.
• Inspect shaft sleeve for wear; replace if needed
(requires disassembly of pump).
• Install new packing rings in stuffing box by placing
over shaft sleeve and pushing them in as far as they
will go.
• Rotate ring joint 90 degrees when installing each ring.
• Slide packing gland into position (gland must enter
stuffing box bore) then gently and evenly tighten nuts
to force rings into place and seat. Loosen nuts to hand
tight.
• Start primed pump and allow packing to leak liberally.
• While pump is running, evenly tighten gland nuts one
complete turn at a time until leakage is reduced to
droplet form (40 to 60 drops per minute).
