d.
Confirm the twisted point with clamp faces in the opposite direc-
tion to adjusting screw within 30
°
as shown in the figure.
e.
After twisting wire 4 to 4.5 turns, bend cut end of wire. Cut end of
wire should not touch boot. Be sure wire end is at least 5 mm
(0.20 in) away from clearance for tube.
23. Install cylinder-tubes to gear housing assembly.
24. Tighten lightly in specified length “L”, then tighten lock nut at
specified torque. Refer to
. Reconfirm
if tie-rod length is within limit of specified length “L”.
CAUTION:
Perform toe-in adjustment after this procedure. Length
achieved after toe-in adjustment is not necessarily value
given here.

CHECKING RELIEF OIL PRESSURE
CAUTION:
Before starting work, confirm belt tension is proper.
1.
Connect oil pressure gauge (SST) and oil pressure gauge
adapter (SST) between oil pump discharge connector and high
pressure hose and then bleed air from the hydraulic circuit.
2.
Start engine. Allow engine to run until tank temperature reaches
50 to 80
°
C (122 to 176
°
F).
CAUTION:
●
Warm up engine with shut-off valve fully opened. If
engine is started with shut-off valve closed, fluid pres-
sure in power steering pump increase to maximum. This
will raise fluid temperature excessively.
●
Be careful not to contact hose with belt when engine is
started.
3.
With engine at idle, close shut-off valve and read the relief oil
pressure.
CAUTION:
Do not close shut-off valve of pressure gauge for more than 10 seconds.
4.
After measurement, open shut-off valve slowly.
●
If relief oil pressure is outside the specification, disassemble and repair oil pump. Refer to
5.
After inspection, disconnect oil pressure gauge (SST) and oil pressure gauge adapter (SST) from hydrau-
lic circuit, connect oil pump discharge connector and high pressure hose. Add fluid and bleed air from
hydraulic circuit thoroughly. Refer to
PS-7, "Air Bleeding Hydraulic System"
Removal and Installation
NGS00019
REMOVAL
1.
Remove engine cover.
2.
Remove air cleaner box.
3.
Drain water from radiator upper tank, then remove radiator upper hose.
4.
Remove radiator fan shroud. Refer to

5.
Loosen idler pulley, then remove belt.
6.
Drain power steering fluid from reservoir tank.
7.
Remove piping of high pressure and low pressure (drain fluid
from their pipings).
8.
Remove bolt common to water pump and power steering pump.
9.
Remove bolt then remove power steering pump.
INSTALLATION
Refer to
for tightening torque. Install in the reverse order of removal.
●
After installation, adjust belt tension. Refer to
●
After installation, bleed air. Refer to

INSPECTION BEFORE DISASSEMBLY
Disassemble power steering oil pump only if the following items are
found.
●
Oil leakage from oil pump
●
Deformed or damaged pulley
●
Poor performance
DISASSEMBLY
NOTE:
Fix oil pump in vise as the occasion demands.
CAUTION:
When retaining drive shaft in a vise, always use copper or aluminum plates between vise and shaft.
1.
Unscrew two front bracket bolts and remove bracket from body assembly.
2.
Unscrew four cover assembly bolts and remove cover assembly from body assembly.
3.
Remove O-ring A from body assembly.
4.
Remove rotor snap ring with snap ring pliers, and remove shaft
kit from body assembly.
CAUTION:
When removing rotor snap ring, be careful not to damage
pulley shaft of shaft kit.
5.
Using a screw driver, remove oil seal for body assembly.
6.
Remove cam ring, rotor, vane, side plate, O-ring B and O-ring C
from body assembly.
7.
Remove plug, then remove O-ring D, flow control valve spring,
relief valve assembly and flow control value assembly from body
assembly.
CAUTION:
Be careful not to drop and deform relief valve assembly and
flow control valve assembly.
8.
Remove fixing bolt of suction connector assembly, then remove
suction connector assembly and O-ring E from body assembly.
INSPECTION AFTER DISASSEMBLY
Body Assembly and Cover Assembly Inspection
●
Check body assembly and cover assembly for damage. If any damage is found, replace with new part for
cover assembly, and replace with new power steering pump assembly for body assembly.
Cartridge Assembly Inspection
●
Check cam ring, side plate, rotor and vanes for damage. If any damage is found, replace cartridge assem-
bly with new one.
Relief Valve Assembly Inspection
●
Check relief valve assembly for damage. If any damage is found, replace it with new one.
