ON−VEHICLE INSPECTION
1. SET REAR AXLE LOAD
Rear axle load (include vehicle weight):
1,330 kg (2,932 lb)
2. INSTALL LSPV GAUGE (SST) AND BLEED AIR SST 09709−29018
3. RAISE FRONT BRAKE PRESSURE TO 7,845 kPa (80 kgf/cm
2, 1,138 psi) AND CHECK REAR BRAKE PRES-
SURE
Rear brake pressure:
5,984 ± 589 kPa (61 ± 6 kgf/cm
2, 869± 86 psi)
HINT:
The brake pedal should not be depressed twice and/or returned
while setting to the specified pressure. Read the value of rear
pressure 2 seconds a fter adjusting the specified fluid pressure.
4. IF NECESSARY, ADJUST FLUID PRESSURE
(a) Disconnect the No.2 shackle from the shackle bracket.
(b) Adjust the length of the No.2 shackle turning it. Low pressure − Lengthen A.
High pressure − Shorten A
Initial set: 90 mm (3.54 in.)
Adjusting range: 84 − 96 mm (3.31 − 3.78 in.)
HINT:
One turn of the No.2 shackle changes the fluid pressure by
about 98.1 kPa (1.0 kgf/cm
2, 14.2 psi).
(c) In event the pressure cannot be adjusted by No.2 shackle, raise or lower the valve body.
Low pressure − Lower
High pressure − Raise
(d) Torque the 2 nuts. Torque: 13 N·m (130 kgf·cm, 9 ft·lbf)
(e) Adjust the length of the No.2 shackle again.
If it cannot be adjusted, inspect the valve housing.

LUBRICATION OIL PUMP
LU−9
1996 LAND CRUISER (RM451U)
INSPECTION
1. INSPECT RELIEF VALVE
Coat the valve with engine oil and check that it falls smoothly
into the valve hole by its own weight.
If it does not, replace the relief valve. If necessary, replace the
oil pump assembly.
2. INSPECT ROTOR BODY CLEARANCE
Using a thickness gauge, measure the clearance between the
driven rotor and body.
Standard body clearance:
0.100 − 0.170 mm (0.0039 − 0.0067 in.)
Maximum body clearance:
0.30 mm (0.0118 in.)
If the body clearance is greater than maximum, replace the ro-
tors as a set. If necessary, replace the oil pump assembly.
3. INSPECT ROTOR SIDE CLEARANCE
Using a thickness gauge and precision straight edge, measure
the clearance between the rotors and precision straight edge. Standard side clearance:
0.030 − 0.090 mm (0.0012 − 0.0035 in.)
Maximum side clearance:
0.15 mm (0.0059 in.)
If the side clearance is greater than maximum, replace the ro-
tors as a set. If necessary, replace the oil pump assembly.
4. INSPECT ROTOR TIP CLEARANCE
Using a thickness gauge, measure the clearance between the
drive and driven rotor tips. Standard tip clearance:
0.030 − 0.160 mm (0.0012 − 0.0063 in.)
Maximum tip clearance:
0.25 mm (0.0098 in.)
If the tip clearance is greater than maximum, replace the rotors
as a set.

LUBRICATION OIL COOLER
1996 LAND CRUISER (RM451U)
INSPECTION
1. INSPECT RELIEF VALVE
Coat the valve with engine oil and check that it falls smoothly
into the valve hole by its own weight.
If it doesn’t, replace the relief valve. If necessary, replace the oil
cooler cover.
2. INSPECT OIL COOLER
Check the oil cooler for damage or clogging.
If necessary, replace the oil cooler.

SUPPLEMENTAL RESTRAINT SYSTEM STEERING WHEEL PAD AND SPIRAL CABLE
RS−17
1996 LAND CRUISER (RM451U)
(f) Cover the steering wheel pad with a cardboard box or
tires.
Covering method using a cardboard box:
Cover the steering wheel pad with the cardboard
box and weight the cardboard box down in 4 places
with at least 190 N (20 kg, 44 lb).
Size of cardboard box:
Must exceed the following dimensions:
x=460 mm (18.11 in.)
When dimension of the cardboard box exceeds the di-
ameter of the disc wheel with tire to which the steer-
ing wheel pad is tied
x=460 mm (18.11 in.) + width of tire
y= 650 mm (25.59 in.)
NOTICE:
If a cardboard box smaller than the specified size is used,
the cardboard box will be broken by the shock from the air-
bag deployment.
Covering method using tires:
Place at least 3 ti res without disc wheel on top of the
disc wheel with tire to which the steering wheel pad
is tied.
Tire size: Must exceed the following dimensions −
Width: 185 mm (7.87 in.)
Inner diameter: 360 mm (14.17 in.)
CAUTION:
Do not use tires with disc wheels.
NOTICE:
The tires may be marked by the airbag deployment, so use
the redundant tires.
(g) Deploy the airbag. (1) Connect the SST red clip to the battery positive (+)
terminal and the black clip to the battery negative
(−) terminal.
(2) Check that no one is within 10 m (33 ft) area around
the disc wheel which the steering wheel pad is tied
to.
(3) Press the SST activation switch and deploy the air- bag.
HINT:
The airbag deploys simultaneously as the LED of the SST ac-
tivation switch lights up.

STEERING POWER STEERING VANE PUMP
1996 LAND CRUISER (RM451U)
HINT:
There are 3 vane plate lengths for the following rotor and cam
ring marks.
3. INSPECT FLOW CONTROL VALVE
(a) Coat the valve with power steering fluid and check that it
falls smoothly into the valve hole by its own weight.
(b) Check the valve for leakage. Close one of the holes and apply 392 − 490 kPa (4 − 5 kgf/cm
2, 57 − 71 psi) of com-
pressed air into the opposite side, and confirm that air
does not come out from the end holes.
Inscribed mark:
A, B, C, D, E or F
4. INSPECT SPRING
Using calipers, measure the free length of the spring. Minimum free length: 35 − 37 mm (1.38 − 1.46 in.)
If it is not within the specification, replace the spring.
