Specification
Intake : 1.0mm(0.0394in.)
Exhaust : 1.3mm(0.0512.)
(4)Check the valve length.
Length
Intake : 110.1mm(4.3346in)
Exhaust : 111.1mm(4.3740in)
(5) Check the surface of the valve stem tip for wear.
If the valve stem tip is worn, replace the valve.
3. Inspect valve seats
(1) Check the valve seat for evidence of overheating or improper contact with the valve face.
If the valve seat is worn, replace cylinder head.
(2) Before reconditioning the seat, check the valve guide for wear. If the valve guide is worn, replace the valve
guide first.
(3) Recondition the valve seat with a valve seat grinder or cutter. The valve seat contact width should be within
specifications and centered on the valve face.
4. Inspect valve springs.
(1) Using a steel square, measure the out - of- square of the valve spring.
(2) Using vernier calipers, measure the free length of the valve spring.
Valve spring
[Standard]
Free height : 46.8mm (1.8425in.)
Out- of- square : 1.5° or less
MLA(Mechanical Lash Adjuster)
1.Inspect MLA.
Using a micrometer, measure the MLA outside diameter.
MLA O.D.
Intake/Exhaust : 29.964 ~ 29.980mm(1.1797 ~ 1.1803in.)
2. Using a caliper gauge, measure MLA tappet bore inner diameter of cylinder head.
Tappet bore I.D.
Intake/Exhaust : 30.000 ~ 30.025mm(1.1811 ~ 1.1821in.)
3. Calculate the clearance by subtracting MLA outside diameter measurement from tappet bore inside diameter
measurement.
MLA to tappet bore clearance
[Standard]
Intake/Exhaust : 0.020 ~ 0.061mm(0.0008 ~ 0.0024in.)
[Limit]
Intake/Exhaust : 0.07mm(0.0027in.) or less
CAMSHAFT
1.Inspect cam lobes.
Using a micrometer, measure the cam lobe height.
Cam height
[Standard value]
Intake : 44.5mm (1.7520in.)
Exhaust : 44.5mm (1.7520in.)
If the cam lobe height is less than standard, replace the camshaft.
2. Check the cam lobe surface for wear or damage. If necessary, replace it.
3. Inspect camshaft journal clearance.
(1) Clean the bearing caps and camshaft journals.
(2) Place the camshafts on the cylinder head.
(3) Lay a strip of plastigage across each of the camshaft journals.
Objective
* Energy (hydraulic pressure) storage
* Impact and pulsation damping when solenoid valves operating
* Operation as spring element
* Smooth shifting by preventing sudden operation of clutches and brakes
TRANSFER DRIVE GEAR
With the transfer drive gear, increased tooth height and a higher contact ratio have reduced gear noise.
Also, the bearing that supports the drive gear is a preloaded type that eliminates rattle, and the rigidity of the gear
mounting has been increased by bolting the bearing directly onto the case.
OUTPUT SHAFT/TRANSFER DRIVEN GEAR
As shown in the illustration below, the transfer driven gear is press- fitted onto the output shaft, and the output shaft is
secured by a locking nut and supported by bearings.
The locking nut has a left- handed thread, and a hexagonal hole in the other end of the shaft enables the shaft to be
held in position for locking nut removal.

AlignmentGo to detailed test E.
DETAILED TEST A : FRONT SUSPENSION NOISE CONDITIONS DETAILS/RESULTS/ACTIONS
ROAD TEST THE VEHICLE
a.Test drive the vehicle.
b. During the road test, drive the vehicle over a rough road. Determine
from which area/component the noise is originating.
● Is there a squeak, creak or rattle noise ?
→ YES
Go to
→ NO
The suspension system is OK. Conduct a diagnosis on other suspect
systems.
INSPECT THE STEERING SYSTEM a.Check the steering system for wear or damage.
Perform a steering linkage test.
Inspect the tire wear pattern.
● Are the steering components worn or damaged ?
→ YES
Repair the steering system. Install new components as necessary. Test
the system for normal operation.
→ NO
Go to
FRONT SHOCK ABSORBER/STRUT CHECK a.Check the front shock absorbers/strut mounts for loose bolts or nuts.
b. Check the front shock absorbers/struts for damage. Perform a shock
absorber check.
● Are the front shock absorbers/struts loose or damaged ?
→ YES
Tighten to specifications if loose.
Install new front shock absorbers/struts if damaged. Test the system for
normal operation.
→ NO
Go to
CHECK THE FRONT SPRINGS Check the front spring and front spring mounts/brackets for wear or
damage
