Open the stuffing box. |
|
Remove the old packing completely. |
|
Check to make sure the new packing
is the correct diameter size. (Stuffing
box gland inside diameter minus shaft
diameter divided by 2 should be the size
of the packing material being used) |
|
Check the condition of the shaft.
Any burrs or sharp areas must be
repaired prior to installation. |
|
Make one wrap GFO fiber packing
around the shaft, wherever it's easily
accessible, and cut each ring (Or use a
mandrel the same size as your shaft to
cut rings). |
|
Install GFO fiber packing in the
stuffing box one ring at a time making
sure that you stagger the joints
approximately 90o. It is
essential that the ends of the rings
meet cleanly at the joint. (Do not
add grease or other lubricants - these
can hinder performance.) |
|
Tighten the packing gland until it
is snug. Do not over tighten. |
|
After about one or two hours of
running time, check the stuffing box
for leakage, and make a final adjustment
to attain minimum leakage. (There
should be virtually no leakage.) |
