Installing New Rings
• Clean shaft sleeve and packing gland.
• Inspect shaft sleeve for wear, replace if needed.
• 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 as
shown.
• Slide packing gland into position (gland must enter stuffing
box bore) then gently and evenly tighten nuts to force rings
into place and seat (do not over tighten). Loosen nuts again
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).
