installation instructions and follow the recommen-

Step 3:
Lubricate all metallic packings (foil type,
lead core, etc.) with the lubricant recommended by
the manufacturer. Generally swabbing the I.D. of
the packing with SAE No. 30 non-detergent oil pro-
vides sufficient lubrication.
Lubricate the new packing rings with non-deterg-
ent oil before installation. For best performance, do
not stretch or separate packing braids. Push each
packing ring through the backhead into the seal
bore and compress it using a blunt ended sleeve
(split in half, same diameter as the split glands) and
mallet. Each successive layer must be com-
pressed and rotated by 90
_
to prevent excessive
leakage.
Be sure
the lantern ring is aligned with
the lubrication port when the packing is fully com-
pressed. Add enough packing to fill the backhead
to within 3/8-inch (9,5 mm) of the end.
Position the split gland halves (07G) on the shaft
and install the gland retainers (07H) over the ends
of the split gland. Install the hardware (B and D)
and tighten in an alternating pattern until the gland
nuts begin to compress the packing.
Do not overtighten the gland nuts. If the
packing rings are compressed too tightly,
they may cause the shaft to overheat and
damage the pump.
Run the pump until it reaches its normal operating
temperature before adjusting the gland nuts. Do
not over-tighten the nuts. Tighten the nuts only
tight enough to reduce excessive leakage.
