Caution, severe damage can occur to
the shaft and stuffing box if you wrap the packing
around and around without cutting individual rings.
Wrap the new packing around a clean
section of the shaft before cutting, making sure
there are no twists as you wrap. If you don't have
enough room to work on the shaft, use a wooden dowel
the same size as your shaft, and cut the rings on
the dowel.
Cut the rings from the spiral wrap at
a 45-degree angle. The rings should completely
circle the shaft, leaving no gaps between cut ends.
Cut and replace the same amount of rings as you
removed. Apply a small amount of waterproof grease
to the shaft. This will prevent wear and excessive
heating until the water can reach the packing to
provide cooling and lubrication. Place each ring on
the shaft, pushing them into the stuffing box.
Stagger them at a 90-degree angle to the preceding
ring. Use a lightweight oil or an antiseize compound
on the gland nut before
