3. Remove injection tube and injection nozzle assembly. Refer to
EC section, ªInjection Tube and Injection Nozzleº in ªBASIC
SERVICE PROCEDUREº.
4. Remove the camshaft.
IPlace distinguishing marks on the right and left sides with paint.
ILoosen and remove the installation bolt in reverse order shown
in the figure.
5. Remove the adjusting shim and valve lifter.
IRemove by taking notice of the installation position, and place
outside engine in order to prevent confusion.
Inspection
VISUAL CHECK OF CAMSHAFT
ICheck the camshaft for one sided wear or scratches.
IReplace the camshaft if there are abnormalities.
CAMSHAFT RUNOUT
IPrepare V-block on a flat surface and secure camshaft journals
No. 1 and No. 5.
ISet the dial gauge vertically on journal No. 3.
IRotate camshaft in one direction by hand, then read needle
movement on dial indicator.
Camshaft bend value is 1/2 of needle movement.
Limit: 0.02 mm (0.0008 in)
HEIGHT OF CAM NOSE
Measure by using a micrometer.
Standard:
Intake
40.488 0.02 mm (1.5940 0.0008 in)
Exhaust
40.850 0.02 mm (1.6083 0.0008 in)
CAMSHAFT OIL CLEARANCE
Measure by using a micrometer.
Cam journal outer diameter:
Standard
29.931 - 29.955 mm (1.1784 - 1.1793 in) dia.

RESURFACING OF CRANKSHAFT JOURNAL AND
CRANK PIN
When using undersize main bearings and connecting rod bearings,
the crankshaft journals or crank pins must be finished to match the
bearings.
R: Crank journal 3.0 mm (0.118 in)
Crank pin 3.5 mm (0.138 in)
CAUTION:
IAt the same time make sure that the surface width does not
increase.
IDo not attempt to cut counterweight of crankshaft.
PILOT BUSHING REPLACEMENT
1. Pull out bushing with Tool.
2. Insert pilot bushing until distance between flange end and
bushing is specified value.
Distance:
Approx. 5.6 - 6.0 mm (0.220 - 0.236 in)
FLYWHEEL RUNOUT
Runout (Total Indicator Reading):
Less than 0.15 mm (0.0059 in)
FRONT PLATE
Check front plate for warpage. If not within the limit, make flat or
replace front plate.
Warpage limit:
0.2 mm (0.008 in)

Front Wheel Alignment
Before checking front wheel alignment, be sure to make a prelimi-
nary inspection.
PRELIMINARY INSPECTION
1. Check the tires for wear and proper inflation.
2. Check the wheel runout.
Wheel runout:
Refer to SDS, FA-39.
3. Check the front wheel bearings for looseness.
4. Check the front suspension for looseness.
5. Check the steering linkage for looseness.
6. Check that the front shock absorbers work properly by using
the standard bounce test.
7. Measure vehicle height (Unladen): H = A þ B mm (in)
Refer to SDS, FA-39.
(1) Exercise the front suspension by bouncing the front of the
vehicle 4 or 5 times to ensure that vehicle is in a neutral height
attitude.
(2) Measure wheel alignment.
Refer to SDS, FA-39.
(3) Measure vehicle posture ... Dimension ªHº.
Refer to SDS, FA-39.
If ªHº dimension is not within the specified value, readjust
vehicle posture using anchor arm adjusting nut.
Refer to ªINSTALLATION AND ADJUSTMENTº, ªTorsion Bar
Springº, FA-31. Adjust wheel alignment if necessary.
(4) If wheel alignment is not as specified, but dimension ªHº is
correct, adjust wheel alignment.
CAMBER, CASTER AND KINGPIN INCLINATION
Before checking camber, caster or kingpin inclination, move
vehicle up and down on turning radius gauge to minimize
friction. Ensure that vehicle is in correct posture (unladen
vehicle).
IMeasure camber, caster and kingpin inclination of both
right and left wheels with a suitable alignment gauge and
adjust in accordance with the following procedures.
