Packing Installation
1.
Before installing the new packing, be sure that all of
the old packing is removed from the seal housing.
2.
Be sure that the seal housing and the shaft are clean
and free of any packing residue.
3.
Lightly lubricate the packing ring I.D. and O.D. with
mineral oil, automotive grease or engine oil for install‐
ation purposes.
4.
Make sure packing is clean.
5.
Carefully install one ring of packing. With the aid of
packing glands, push the packing into the seal housing
as far as possible. Repeat this operation with each ring,
staggering the joints at least 90
_
apart. Install the pack‐
ing rings until the top of the last ring is about 1/4 inch
from the end of the seal housing (at least 1/8 inch is
required for the packing gland nose entrance into the
stuffing box).
NOTE: Be sure that the packing joints are
staggered at least 90
_
apart.
6.
Install packing glands, nuts and washers. Tighten
gland nuts one flat beyond finger tight.
NOTE: The milled slot on the nut should face the
gland.
