ON−VEHICLE INSPECTION
1. CHECK THAT SPARK OCCURS
(a) Disconnect the high −tension cords (from the ignition coil)
from the distributor cap.
(b) Hold the end approx. 12.5 mm (0.50 in.) from the body ground.
(c) Check if spark occurs while engine is being cranked.
HINT:

If necessary, remove the cylinder head cover, and check these
conditions:
Turn the crankshaft pulley and align its groove with
the timing mark ”0” of the timing chain cover.

straight line on the cylinder head surface as shown
in the illustration.
If not, turn the crankshaft 1 revolution (360°) and align the mark
as above.
2. INSTALL DISTRIBUTOR
(a) Install a new O−ring to the distributor.
HINT:
Always use a new O −ring when installing the distributor.
(b) Align the groove of the distributor housing with the protru-
sion on the driven gear.
(c) Apply a light coat of engine oil on the O −ring.
(d) Insert the distributor, aligning the center of the flange with
that of the bolt hole on the cylinder head.
(e) Lightly tighten the hold −down bolt.

OIL AND FILTER
INSPECTION
1. CHECK ENGINE OIL QUALITY
Check the oil for deterioration, entry of water, discoloring or thin-
ning.
If the quality is visibly poor, replace the oil.
Oil grade:
API grade SH Energy−Conserving II multigrade en-
gine oil or ILSAC multigrade engine oil.
Recommended viscosity is as shown in the illustra-
tion, with SAE 5W −30 being the preferred engine oil.
2. CHECK ENGINE OIL LEVEL
The oil level should be between the ”L” and ”F” marks on the di\
p-
stick.
If low, check for leakage and add oil up to ”F” mark.
3. REMOVE OIL PRESSURE SWITCH, AND INSTALL OIL
PRESSURE GAUGE
4. WARM UP ENGINE
Allow the engine to warm up to normal operating temperature.
5. CHECK OIL PRESSURE Oil pressure:
At idle
29 kPa (0.3 kgf/cm
2, 4.3 psi) or more
At 3,000 rpm
245 − 490 kPa (2.5 − 5.0 kgf/cm
2, 36 − 71 psi)
6. REMOVE OIL PRESSURE GAUGE AND REINSTALL OIL PRESSURE SWITCH
(a) Remove the oil pressure gauge.
(b) Apply adhesive to 2 or 3 threads of the oil pressure switch.

REPLACEMENT
CAUTION:
Prolonged and repeated contact with mineral oil will result
in the removal of natural fats from the skin, leading to dry-
ness, irritation and dermatitis. In addition, used engine oil
contains potentially harmful contaminants which may
cause skin cancer.Care should be taken, therefore, when
changing engine oil to minimize the frequency and length
of time your skin is exposed to used engine oil. Protective
clothing and gloves that cannot be penetrated by oil should
be worn. The skin should be thoroughly washed with soap
and water, or use water−less hand cleaner, to remove any
used engine oil. Do not used gasoline, thinners, or sol-
vents.In order to preserve the environment, used oil and
used oil filters must be disposed of only at designated dis-
posal sites.
1. DRAIN ENGINE OIL
(a) Remove the oil filler cap.
(b) Remove the oil drain plug, and drain the oil into a contain-
er.
2. REPLACE OIL FILTER
(a) Using SST, remove the oil filter. SST 09228−44011
(b) Check and clean the oil filter installation surface.
(c) Apply clean engine oil to the gasket of a new oil filter.
(d) Lightly screw the oil filter into place, and tighten it until the
gasket contacts the seat.
(e) Using SST, tighten it an additional 3/4 turn. SST 09228−44011
3. FILL WITH ENGINE OIL
(a) Clean and install the oil drain plug with a new gasket.
Torque: 25 N·m (250 kgf·cm, 18 ft·lbf)
(b) Fill with new engine oil. Oil grade:
See step 1 in oil pressure check

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.
