Oil Reservoirs
Refer to F
IG
. 14 for reference numbers used in the
following instructions.
Disassembly
The disassembly procedure may be performed with the
reservoir mounted on the pump. However, some mount-
ing locations may be too restrictive to provide access to
all components.
If installation requires dismounting of the reservoir,
make sure the reservoir is drained of lubricant before
removing the attaching hardware. This will reduce the
weight of the reservoir and reduce the chance of spill-
age.
1. Drain oil (see Preparing for Maintenance on page
17). Allow oil to drain into bucket or similar container
and properly dispose of emptied oil.
2. Remove three hex nuts (1) and lock washers (5)
from tie rods (3).
3. Remove tie rods (3) from reservoir cover (9).
4. Remove reservoir cover (9) from reservoir (11).
5. Remove fill screen (30) from fill cap (31) and clean
screen.
6. Remove reservoir (11) from pump.
7. Remove and discard gasket (8) from pump.
Assembly
1. Install fill screen (30) in fill cap (31).
2. Install new gasket (8) in pump.
3. Position reservoir (11) on pump and position reser-
voir cover (9) on tube.
4. Align holes in reservoir cover (9) and holes in pump.
Install tie rods (3) through holes in cover and pump.
The heads of tie rods (3) must fit into the hexagonal
depressions on the upper surface of the reservoir
cover (9).
5. Install lock washers (5) and hex nuts (1) on tie rods
(3).
6. Torque nuts to 5 ft-lbs (6.78 N.m).
NOTE: When the assembly is completed any com-
ponents which were removed to ease disassembly
should be reinstalled on the reservoir.
