d) Assembly skid is bolted tightly against
baseplate making track completely
immobile.
7) Lubricate top of track so that cartridge
assembly will slide easily.
8) Remove the case stud nuts [6580.2] and
washers [2905].
9) Install an eyebolt at the top of the casing cover
[1221] and attach soft cables and a hoist.
Tension the cables to support the weight of
the head.
When a pump has been in service a long
time, especially in high temperature service, it may
be necessary to drive a steel wedge between the
head and the end of the case at three evenly
spaced places around the circumference of the
head before separation can be accomplished. But,
when possible, push the head loose from the case
with the jack screws.
The head fits closely with a clearance of 0.001 to
0.004 inch (0.03 to 0.10 millimeters) between the
head and bore of the case. Hence, you must take
care to pull the head straight out of the case after
breaking it loose with jack screws.
10) Install jack screws in the casing cover [1221]
and break the casing cover away from the
casing [1100]. If necessary, drive steel
wedges in between the casing cover and
casing at three evenly spaced locations
around casing cover to break it loose.
11) Use pry bars and a winch to pull the cartridge
assembly out of casing. Pull the cartridge
assembly out far enough to install a nylon
lifting strap around its center of gravity, but do
not pull assembly completely out of the case.
12) Place wooden blocks under casing cover
[1221] to support the assembly. Remove the
hoist from the eyebolt in the head and attach it
to a nylon lifting strap located at the center of
gravity of the assembly.
13) Carefully lift cartridge assembly off of blocks
and remove it from the case. Remove the
case end plate gasket [4590.4] from the case
and/or case end plate and discard.
14) Install the cartridge assembly in the alignment
tool (
Figure 6-7
) for transport as follows:
a) Insert the coupling end of the cartridge
assembly into the alignment tool.
b) When the nylon strap binds, place wooden
blocks under casing cover [1221] to
support the assembly. Remove the hoist
from the nylon lifting strap and attach it to
an eyebolt in the head, and tension the
cable to support the weight of the
cartridge assembly.
c) Continue to push the cartridge assembly
into the alignment tool, using a hydraulic
ram if necessary.
d) Install the studs provided with alignment
tool through casing cover [1221]], then
secure the cartridge assembly with the
spacer and nuts provided.
e) Loosen but do not remove the tension
flange jack screws.
f) Install and tighten either the suction end
plate cap screws [6570.3] or O-ring
retainer cap screw [6570.3] which is
applicable.
Figure 6- 7 : Typical Alignment Tool
15) Further disassembly of the cartridge assembly
should be accomplished in a suitable area
such as a workshop. The cartridge assembly
may also be placed into storage in the
alignment tool at this time until it may be
serviced or reinstalled.
16) Prior to disassembly of the cartridge element,
the cartridge element should be removed from
the alignment tool (
Figure 6-7
) as follows:
a) Remove either the suction end plate cap
screws [6570.3] or O-ring retainer cap
screw [6570.3] which is applicable.
b) Tighten the jack screws in the tension
flange against the bearing housing until
snug.
c) Install an eyebolt in the top of the casing
cover [1221] and attach soft cables and a
hoist. Tension the cables to support the
weight of the head.
d) Remove the studs, nuts & spacer provided
with the alignment tool. Then use pry bars
and a winch to pull the cartridge assembly
out of the alignment tool. Pull the cartridge
assembly out far enough to install a nylon
lifting strap around its center of gravity, but
do not pull cartridge assembly completely
out of the alignment tool.
e) Place wooden blocks under casing cover
[1221] to support the assembly. Remove
the hoist from the eyebolt in the head and
