INSPECTION
1. INSPECT TIMING CHAIN AND TIMING GEARS
(a) Measure the length of 16 links with the chain fully
stretched.
Maximum chain elongation: 146.6 mm (5.772 in.)
If the elongation is greater than maximum, replace the chain.
HINT:
Make the same measurements pulling at 3 or more places se-
lected at random.
(b) Wrap the chain around the timing gear.
(c) Using vernier calipers, measure the timing gear diameter with the chain.
NOTICE:
Vernier calipers must contact the chain rollers for measur-
ing.
Minimum gear diameter (w/Chain):
Camshaft126.0 mm (4.961 in.)
Crankshaft65.4 mm (2.575 in.)
If the diameter is less than minimum, replace the chain and
gears.
2. INSPECT CHAIN TENSIONER SLIPPER AND VIBRA-TION DAMPER
Measure the chain tensioner slipper and vibration damper
wears. Maximum wear: 1.0 mm (0.039 in.)
If the wear is greater than maximum, replace the slipper and/or
damper.
3. INSPECT OIL JET
Check the oil jet for damage or clogging.
If necessary, replace the oil jet.

(d) Remove the camshaft timing gear and chain from the in-
take camshaft and leave on the slipper and damper.
35. REMOVE CAMSHAFTS
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be kept level while it is being removed. If the
camshaft is not kept level, the portion of the cylinder head
receiving the shaft thrust may crack or be damaged, caus-
ing the camshaft to seize or break. To avoid this, the follow-
ing steps should be carried out.
(a) Remove the exhaust camshaft. (1) Bring the service bolt hole of the driven sub −gear
upward by turning the hexagon wrench head por-
tion of the exhaust camshaft with a wrench.
(2) Secure the exhaust camshaft sub −gear to the main
gear with a service bolt.
Recommended service bolt:
Thread diameter6 mm
Thread pitch1.0 mm
Bolt length16 − 20 mm (0.63 − 0.79 in.)
HINT:
When removing the camshaft, make sure that the torsional
spring force of the sub −gear has been eliminated by the above
operation.
(3) Set the timing mark (2 dot marks) of the camshaftdriven gear at approx. 35 ° angle by turning the
hexagon wrench head portion of the intake cam-
shaft with a wrench.
(4) Lightly push the camshaft towards the rear without applying excessive force.
(5) Loosen and remove the No. 1 bearing cap bolts, al-
ternately loosening the left and right bolts uniformly.

(d) Check the valve overall length.
Standard overall length:
Intake98.4 mm (3.874 in.)
Exhaust97.4 mm (3.854 in.)
Minimum overall length:
Intake97.9 mm (3.854 in.)
Exhaust97.4 mm (3.835 in.)
If the overall length is less than minimum, replace the valve.
(e) Check the surface of the valve stem tip for wear.
If the valve stem tip is worn, resurface the tip with a grinder or
replace the valve.
NOTICE:
Do not grind off more than minimum.
7. INSPECT AND CLEAN VALVE SEATS
(a) Using a 45° carbide cutter, resurface the valve seats.
Remove only enough metal to clean the seats.
(b) Check the valve seating position. Apply a light coat of prussian blue (or white lead) to the
valve face. Lightly press the valve against the seat. Do not
rotate valve.
(c) Check the valve face and seat for the following:
If blue appears 360 ° around the face, the valve is
concentric. If not, replace the valve.
If blue appears 360 ° around the valve seat, the
guide and face are concentric. If not, resurface the
seat.
Check that the seat contact is in the middle of the
valve face with these width:
Intake1.2 − 1.6 mm (0.047 − 0.063 in.)
Exhaust1.0 − 1.4 mm (0.039 − 0.055 in.)

If not, correct the valve seats as follows: (1) Intake:If the seating is too high on the valve face, use 30 °
and 45 ° cutters to correct the seat.
(2) If the seating is too low on the valve face, use 75° and 45 ° cutters to correct the seat.
(d) Hand−lap the valve and valve seat with an abrasive com- pound.
(e) After hand−lapping, clean the valve and valve seat.
8. INSPECT VALVE SPRINGS
(a) Using a steel square, measure the deviation of the valve spring.
Maximum deviation: 2.0 mm (0.079 in.)
If the deviation is greater than maximum, replace the valve
spring.
(b) Using vernier calipers, measure the free length of the valve spring.
Free length: 43.94 − 45.06 mm (1.7299 − 1.7740 in.)
If the free length is not as specified, replace the valve spring.

(c) Using a spring tester, measure the tension of the valve
spring at the specified installed length.
Installed tension:
214 − 238 N (21.8 − 24.2 kgf, 48.1 − 53.4 lbf)
at 36.5 mm (1.437 in.)
If the installed tension is not as specified, replace the valve
spring.
9. INSPECT CAMSHAFTS
(a) Inspect for runout. (1) Place the camshaft on V−blocks.
(2) Using a dial indicator, measure the circle runout atthe center journal.
Maximum circle runout: 0.06 mm (0.0024 in.)
If the circle runout is greater than maximum, replace the cam-
shaft.
(b) Inspect the cam lobes. Using a micrometer, measure the cam lobe height.
Standard cam lobe height:
50.61 − 50.71 mm (1.9925 − 1.9965 in.)
Minimum cam lobe height: 50.51 mm (1.9886 in.)
If the cam lobe height is less than minimum, replace the cam-
shaft.
(c) Inspect the journals. Using a micrometer, measure the journal diameter.
Journal diameter:
26.959 − 26.975 mm (1.0614 − 1.0620 in.)
If the journal diameter is not as specified, check the oil clear-
ance.
(d) Inspect the camshaft bearings. Check that bearings for flaking and scoring.
If the bearings are damaged, replace the bearing caps and cyl-
inder head as a set.

LUBRICATION OIL AND FILTER
1996 LAND CRUISER (RM451U)
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.
