Option #2: Replacing Pack-

ing Components

Because the stainless steel packing housing

components are very durable, it may be more

cost effective to change only those packing

components that will wear over time. Using

this method, you will need DUX Part Number

#310130—the Wearable Packing Component

Kit.

To replace the components, first follow steps

1-4 on the previous page to remove the pack-

ing cartridge. Then follow these steps:

Removing the packing components

Unthread the knurled Spring Cap by hand

until it releases from the cartridge housing.

2. Remove the Sleeve B Spring and Sleeve B

to expose the brass Fluid Seal Nut on the inside

of the packing cartridge housing.

Use a flat bladed screwdriver or the

packing replacement tool to remove the nut by

turning counterclockwise (be careful as there is

a spring beneath the cap).

Turn the housing upside down to re-

move the nut and spring. Note that the spring

is sized for an interference fit inside the base

of the nut, so they should come out as a single

unit.

Use the pointed end of the packing

replacement tool to push/pick the PTFE fluid

seal and black o-ring out of the base of the

housing. It may be easiest to access these

pieces from the outside of the housing. Clean

the inside of housing thoroughly before insert-

ing new packing components.

Important: Be careful when removing the

Spring Cap & Packing Nut-Content are under

spring pressure and may pop loose

Figure 14: Packing on tool

Using the packing replacement tool,

line up the replacement components as shown

in Figure14. Be sure the slot on the brass nut

lines up with the cross piece on the tool so the

tool can be used as a screwdriver to turn the

nut.

Push the components into the canal

on the inside of the housing as shown in Figure

15. When the brass nut seats at the base of the

housing, begin turning clockwise to thread the

nut.

Thread the nut as far as it will go and

keep turning until hand tight.

Insert the new Sleeve B and then the

new Sleeve B Spring (included in the kit) back

into the packing cartridge housing in the order

shown in Figure 15.

Use the Spring Cap to compress the

Spring until you are able to thread the cap back

onto the housing.

Follow steps 6-7 on the previous

page to re-install the cartridge.
