2.5 OIL RESERVOIR MAINTENANCE
(OPTIONS OP1 THROUGH OP4)
2.5.1 General. Maintenance tips, disassembly, and as-
sembly procedures for oil reservoirs are discussed in Para-
graphs 2.5.2, 2.5.3 and 2.5.4. An exploded view of a typical oil
reservoir is shown in Figure 2-2 and should be referred to
during the discussion.
2.5.2 Oil Reservoir Maintenance.
2.5.2.1 Maintenance on the oil reservoir consists of the
following:
a. Visually check for oil leakage between reservoir tube (6,
Figure 2-2) and base (8). Leakage may indicate that the
gasket (7) is defective or that nuts (9) are not tight.
Torque nuts (9) to 5 ft lbs. If leakage continues, replace
gasket (7). Check for cracks and nicks on tube (6).
Replace the tube as required.
b. Visually check screen (2) in fill cup (3) to make sure it is
not clogged. If necessary, remove the screen for clean-
ing.
c. Check reservoir bottom for debris. Clean as required.
WARNING
Disconnect and lock out power before opening
electrical enclosures or conduit connections.
Serious injury may result from electrical shock.
2.5.3 Disassembly of Oil Reservoir. Figure 2-2 shows a
typical oil reservoir but does not include other Modu-Flo
components which may be mounted to the reservoir. These
components include the manifold, pump, level switches and
high-pressure blowout switches. Disassembly of the reser-
voir may require that some of these components be re-
moved. The manifold and pump do not normally require
removal, but may be removed if desired. The level and blow-
out switches may or may not require removal, depending on
the level of disassembly required. The electrical connections
to the switches should be disconnected in order to remove
various parts without restriction of movement by the electrical
cord. The removal of these components is explained in other
sections of the manual. Refer to the table of contents to find
where the components are discussed.
2.5.3.1 The disassembly procedure may be performed with
the reservoir mounted to the mounting surface. However,
some mounting locations may be too restrictive to provide
access to all components. If your particular installation re-
quires dismounting of the reservoir, make sure the reservoir
is drained of lubricant before removing the attaching hard-
ware. This will reduce the weight of the reservoir and reduce
the chance of spillage. The disassembly procedure is as
follows:
a. Remove pipe plug (4, Figure 2-2) from base (8) and
allow oil to drain from reservoir into bucket or similar
container. Properly dispose of emptied oil.
b. Remove three hex nuts (9) and three lockwashers (10)
from tie rods (1). Remove tie rods (1) from reservoir cap
(5).
c. Remove reservoir cap (5) from reservoir tube (6).
d. Remove fill screen (2) from fill cup (3) and clean screen.
e. Remove reservoir tube (6) from base (8).
f. Remove and discard gasket (7) from reservoir tube (6).
2.5.4 Assembly of Oil Reservoir.
NOTE
Before assembly, lubricate followers and tube
inner diameter with the lubricant which is used
in the system.
2.5.4.1 Assemble the oil reservoir according to the follow-
ing procedure:
a. Install screen (2, Figure 2-2) in fill cup (3).
b. Install new gasket (7) on reservoir tube (6).
c. Position reservoir tube (6) on base (8) and position
reservoir cap (5) on tube.
d. Rotate reservoir cap (5) until tie rods (1) can be installed
through holes in cap and in base (8). The heads of tie
rods (1) must fit into the hexagon depressions on the
upper surface of the reservoir cap (5).
e. Install lockwashers (10) and hex nuts (9) on tie rods (1).
Torque nuts to 5 ft lbs.
f. Install pipe plug (4) in base (8).
2.5.4.2 When the assembly steps listed in the above para-
graph have been completed, any Modu-Flo components
which were removed to ease disassembly should be rein-
stalled on the reservoir.
2.5.5 Oil Reservoir Parts Lists. Table 2-3 identifies the
parts indexed in Figure 2-2.
