c) Assemble the line bearing cover [3260] over the
shaft and squarely into the bearing frame bore.
Fasten to the bearing frame with capscrews,
washers and hex nuts. Tighten firmly, but not
excessively.
d) Assemble the deflector [2540] loosely over the shaft
but do not tighten the set screws.
e) Install the coupling key [6700] and tape to the shaft.
f) Rotate the shaft and check that runout does not
exceed 0.002 inch [0.050 mm).
6.10.5.2 Frames 5 & 6
a) Install the lip seal [4300] into the line bearing
cover [3260].
b) Assemble the gasket [4590.4] onto the face of the
line bearing cover [3260].
c) Assemble the line bearing cover [3260] over the
shaft and squarely into the bearing frame bore.
Fasten to the bearing frame with capscrews,
washers and hex nuts. Tighten firmly but not
excessively.
d) Assemble the deflector [2540] with a slight gap
(0.06") to the line bearing cover [3260].
e) Install the coupling key [6700] and tape to the
shaft.
f) Rotate the shaft and check that run-out does not
exceed 0.002 inch (0.050 mm).
6.10.6 Stuffing box
6.10.6.1 All
a) Install the gland studs [6572] using Loctite grade A
or equivalent. Install the square head plugs [6569] in
the stuffing box as required using pipe sealant.
b)
Install the shaft sleeve onto the shaft. The hock
type sleeve must be seated against the shaft
shoulder. Application of Loctite is not necessary
as impeller tightening torque during operation is
sufficient to ensure sleeve rotation.
6.10.6.2 Standard packing
a) Install the protector plate [4132] in the stuffing box
head [4100]. Heavy grease may be applied to
mating faces to help hold it in position while
assembling the stuffing box head to the gland side
wear plate [1915].
b) With gland side wear plates facing up, lift the
stuffing box head [4100] and lower onto the wear
plate.
c) Place the seal washers [4590] over the studs
followed by the steel washers. Apply Loctite 242
or equivalent to nut threads and fasten wear plate
in position. Torque nuts per table.
d) Assemble the stuffing box head [4100] over the
shaft sleeve [2445] and orientate the lantern ring
connections to suit auxiliary pipe These
connections are normally placed on the vertical
centerline for proper venting and draining as well
as providing optimum gland stud access.
e) Push the stuffing box head [4100] back against
the pedestal support flange face and clamp into
position. Back off the thrust bearing housing jack
screw and tighten the thrust bearing housing hold
down capscrews to slide the rotor assembly
forward such that the end face of the shaft sleeve
[2445] protrudes beyond the face of stuffing box
head (standard packed pumps only).
f)
Install the shaft sleeve gasket [4590] on the shaft,
ensuring that the outside diameter is no larger
than the sleeve.
6.10.6.3 Optional expeller seal-frame 1, 2, 3 & 4
a) Assemble the stuffing box [4100] over the sleeve
[2445] and into the bearing frame [3122] register.
Orient the grease fitting to suit the installation. Note
that if the optional solid gland with lip seal design is
used, it must be installed first.
b) Install O-ring onto the expeller stuffing box (corner
for frames 1 & 2, groove for frames 3 & 4). Install
expeller wearplate [1915.3] onto the stuffing box.
Some units may be built with a 1 pc stuffing
box/wearplate. In this cause this step will be
eliminated.
c) Install the expeller [2250] over the shaft sleeve.
Expeller should seat against the sleeve shoulder
but be clear of the expeller wearplate [1915.3].
Adjust the shaft [2100] forward to ensure that the
expeller [250] when installed will not bind against the
stuffing box head [4100].
d) Install gasket [4590.4] over expeller to face of
stuffing box [4100].
e) Install expeller housing [4110] to stuffing box
[4100], clamp in place.
6.10.6.4 Optional expeller seal-frame 5
a) Install the gland studs [6572] into the loose
stuffing box [4100] using Loctite grade A or
equivalent. Install the square head plug [6569]
and grease nipple [6569] in the stuffing box as
required using pipe sealant. For further
information see sections on packing earlier in this
manual.
b) Install studs in expeller wearplate [1915.3], secure
using Loctite #242.
c) Mount gasket [4590.3] onto wearplate [1915.3]
and install loose stuffing box [4100]. Note location
of grease nipple relative to any lifting facility.
d) Assemble the expeller wearplate/stuffing box over
the sleeve [2445] and into the adaptor support
[3120] register. Orientate the grease fitting to suit
the installation. Clamp in position for safety.
e) Adjust the shaft [2100] forward to ensure that the
expeller [2250] when installed will not bind against
the expeller wearplate [1915.3].
