Refer to F

following instructions.
Disassembly
The disassembly procedure may be performed with the
reservoir mounted on the pump assembly. However,
some mounting locations may be too restrictive to pro-
vide access to all components.
If installation requires dismounting of the reservoir, drain
the reservoir of lubricant before removing the attaching
hardware. This reduces the weight of the reservoir and
reduces the chance of spillage.
1. Follow Prepare for Maintenance , see page 16.
2. Drain the oil into a container and properly dispose of
emptied oil.
3. Remove the three hex nuts (1) and lock washers (5)
from the tie rods (3).
4. Remove the tie rods (3) from the reservoir cover (9).
5. Remove the reservoir cover (9) from the reservoir
(11).
6. Remove the fill screen (30) from the fill cap (31) and
clean the screen.
7. Remove the reservoir (11) from the pump.
8. Remove and discard the gasket (8) from the pump.
Reassembly
1. Install the fill screen (30) in the fill cap (31).
2. Install a new gasket (8) in the pump.
3. Position the reservoir (11) on the pump and position
the reservoir cover (9) on the tube.
4. Align the holes in the reservoir cover (9) and the
holes in pump.
5. Install the tie rods (3) through the holes in the cover
and the pump. The heads of the tie rods (3) must fit
into the hexagonal depressions on the upper sur-
face of the reservoir cover (9).
6. Install the lock washers (5) and hex nuts (1) on the
tie rods (3).
7. Torque the hex nuts to 5 ft-lbs (6.78 N.m).
NOTE: After reassembly, any components removed to
ease disassembly should be reinstalled on the reservoir.
