shaft, whichever is applicable (see assembly
drawing).
3) Keep half-coupling on lube oil pump shaft
aligned with spider so that half-coupling on lube
oil pump shaft will mesh with spider and flanges
of lube oil pump and bearing end cover [3266]
will butt together solidly. Run cap screws
through holes in lube oil pump and evenly and
tightly screw cap screws into bearing end cover
[3266], securing lube oil pump to cover.
4) Insure that conduit for vibration probe wires, key
phasor, or pipe plug is installed in largest
diameter hole in top of bearing end cover [3266].
5) Connect piping to lube oil pump.
6) Connect drain pipe to outboard bearing end
cover [3266].
7) Install drain plug in outboard thrust bearing
housing [3230].
6.9.7 Cartridge Assembly Install
To install the cartridge assembly in the pump case
[1100], proceed as follows:
1) Remove the cartridge assembly from the
alignment tool (
Figure 6-7
) as follows:
a) Remove either the 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 stud, 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 casing cover
[1221] and attach it to a nylon lifting strap
located at the center of gravity of the
assembly.
f) Carefully lift cartridge assembly off of blocks
and remove it from the alignment tool.
2) Secure assembly skid (see
Figure 6-6
) or
equivalent device to end of baseplate. To avoid
subjecting cartridge assembly to binding or
twisting stresses or having it roll off of the track,
ensure:
a) Assembly skid is aligned and leveled with
bore of casing [1100]
b) Flange of assembly skid presses solidly
against the baseplate.
c) Feet press against a solid surface across
their entire area
d) Assembly skid is bolted tightly against
baseplate making track completely immobile.
3) Lubricate top of track so that cartridge assembly
will slide easily.
4) Install a new head gasket [4590.3] and a new
suction end plate gasket [4590.4] (if applicable)
on the cartridge assembly. Ensure that the
gaskets remain in their proper positions while
inserting the cartridge assembly into the case
[1100].
5) Insert the coupling end of the assembly into the
case. Carefully align the cartridge assembly rail
[9363] with the casing guide rail key [6700.7].
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
casing cover [1221], and tension the cable to
support the weight of the casing cover. Continue
to push the cartridge assembly into the case
[1100], using a hydraulic ram if necessary.
6) Install the case stud washers [2905] and case
stud nuts [6572.2]. Torque the nuts using the
procedure specified in section 10.3 Operating
Specifications.
7) Remove assembly skid if installed.
8) Loosen the jack screws on the cartridge
assembly tension flange (see
Figure 6-5
), then
remove the coupling lock nut [7411] and the
tension flange.
9) Install either, the suction end cover cap screws
[6570.3] if applicable or O-ring [4610.2], O-ring
retainer [2530.1], and O-ring retainer cap screws
[6570.3], then tighten them firmly and evenly.
10) Install any interfering piping, wiring, or
instrumentation that was removed to permit
disassembly.
6.9.8 Coupling Installation
The procedures outlined in this
subsection do not apply to keyless hydraulic fit
couplings. For installation or removal of such
couplings, refer to the applicable drawings in the
back of this manual.
Ensure that any shipping bolts or packaging material
are removed from the coupling prior to operation of
the pump. (See coupling drawing in the back of this
manual.)
Use of odd size bolts and nuts in the spacer will
cause imbalance; use only bolts and nuts specified
by the coupling manufacturer. Lubrication of the
coupling (see section 10 for manufacturer's
