Using plastigage
1. Wipe off oil from camshaft journal bracket caps and brackets.
2. Install camshaft in journal bracket caps and put plastigage on
each camshaft journal.
3. Install cam bracket caps and tighten cam bracket cap nuts in
the correct order to the specified torque.
: 18 - 22 N´m (1.8 - 2.2 kg-m, 13 - 16 ft-lb)
4. Remove cam bracket caps and measure maximum width of
plastigage.
Camshaft bearing clearance:
Limit
0.1 mm (0.004 in)
5. If clearance appears to exceed the limit, replace camshaft or
cylinder head.
IWhich parts to be replaced should be decided upon after mea-
suring the diameters of the parts concerned.
Valve clearance
Checking
Check valve clearance while engine is warm and not running.
1. Remove rocker cover.
2. Set No. 1 cylinder at TDC on its compression stroke.
IAlign pointer with TDC mark on crankshaft pulley.
ICheck that valve lifters No.

lifters No.
p7andp8are tight.
If not, turn crankshaft one revolution (360É) and align as
described above.

Assembly
1. Install valve component parts.
Install valve spring with its narrow pitch side toward cylinder
head side.
IAlways install new valve oil seals.
Refer to oil seal replacement.
IBefore installing oil seal, install valve-spring seat.
IWhen installing valve, apply engine oil on the valve stem
and lip of valve oil seal.
ICheck whether the valve face is free from foreign matter.
IInstall valve spring retainers on the intake side and valve
rotators on the exhaust side.
IValve rotators cannot be disassembled.
IInstall valve shims
IAdjust valve clearance
2. Install camshaft and brackets and tighten bracket nuts to the
specified torque in two or three stages.
Camshaft-bracket nuts:
: 18 - 22 N´m (1.8 - 2.2 kg-m, 13 - 16 ft-lb)
ITighten bracket from center to outside.
IApply sealant to brackets No. 1 and No. 5.
IWhen installing brackets, set camshaft so that the pin of
camshaft front head is uppermost.
IInstall new camshaft oil seals.
Refer to oil seal replacement.
Installation
1. Install cylinder head gasket.
IWhen replacing only cylinder head gasket, install same
grade gasket as the one formerly used.
IWhen replacing or repairing cylinder block, piston, con-
necting rod and crankshaft, select gasket referring to
ªSelecting cylinder head gasketº.
IPay attention to the direction of the cylinder head bolt
washer as shown in the figure.
2. Install cylinder head and tighten cylinder head bolts according
to the following sequence.

Reboring
1. The size to which cylinders must be honed, is determined by
adding piston-to-cylinder clearance to the piston skirt diameter
ªAº.
Dimension ªaº:
Approximately 62 mm (2.44 in)
Rebored size calculation
D=A+BþC=A+[0.03 to 0.05 mm
(0.0012 to 0.0020 in)]
where,
D: Honed diameter
A: Skirt diameter as measured
B: Piston-to-wall clearance
C: Machining allowance
0.02 mm (0.0008 in)
2. Install main bearing caps and tighten bolts to the specified
torque. This will prevent distortion of cylinder bores.
3. Cut cylinder bores in the order of 2-4-1-3.
Do not cut too much out of the cylinder bore at a time. Cut only
0.05 mm (0.0020 in) or so in diameter at a time.
4. Hone the cylinders to the required size referring to SDS (EM-
199).
5. Measure the finished cylinder bore for out-of-round and taper.
Measurement of a just machined cylinder bore requires
utmost care since it is expanded by cutting heat.
PISTON-TO-BORE CLEARANCE
Using micrometer
1. Measure piston and cylinder bore diameter.
Piston diameter ªAº:
Refer to SDS (EM-199).
Measuring point ªaº (Distance from the bottom):
Approximately 62 mm (2.44 in)
Bore diameter ªDº:
Refer to SDS (EM-199).
Measuring point (Distance from the top):
Approximately 70 mm (2.76 in)
2. Check that piston clearance is within the specification.
Piston clearance (D þ A):
0.030 - 0.050 mm (0.0012 - 0.0020 in)

Precautions
lWhen installing each rubber part, final tightening must
be carried out under unladen condition* with tires on
ground.
*: Fuel, radiator coolant and engine oil full. Spare tire,
jack, hand tools and mats in designated positions.
lWhen removing each suspension part, check wheel
alignment and adjust if necessary.
lUse Tool when removing or installing brake tubes.
lAlways torque brake lines when installing.

PRECAUTIONS AND PREPARATION
FA-2

Front Axle and Front Suspension Parts
Check front axle and front suspension parts for excessive play,
cracks, wear or other damage.
lShake each front wheel to check for excessive play.
lEnsure that new cotter pins are used, and are correctly fit-
ted.
lRetighten all axle and suspension nuts and bolts to the speci-
fied torque.
Tightening torque:
Refer to FRONT SUSPENSION, FA-26.
lCheck strut (shock absorber) for oil leakage or other dam-
age.
lCheck suspension ball joint for grease leakage and ball joint
dust cover for cracks or other damage.
If ball joint dust cover is cracked or damaged, replace trans-
verse link.

FRONT WHEEL TURNING ANGLE
1. Set wheels in straight-ahead position. Then move vehicle
forward until front wheels rest on turning radius gauge prop-
erly.
2. Rotate steering wheel all the way right and left; measure
turning angle.
lOn power steering models, turn steering wheel to full lock
and apply force (at circumference of steering wheel) of 98 to
147 N (10 to 15 kg, 22 to 33 lb) with engine at idle.
Do not hold the steering wheel at full lock for more than
15 seconds.
Wheel turning angle (Full turn):
Refer to SDS, FA-35.

VICEº, FA-6.
INSPECTION
Transverse link
lCheck transverse link for damage, cracks or deformation.
Replace it if necessary.
lCheck rubber bushing for damage, cracks and deformation.
Replace transverse link if necessary.
Lower ball joint
lCheck ball joint for excessive play. Replace transverse link
assembly if any of the following exists:
lBall stud is worn.
lJoint is hard to swing.
lPlay in axial direction is excessive.
Before checking, turn ball joint at least 10 revolutions so that
ball joint is properly broken in.
