Checking Drive BeltsEBS01EJ4
lBefore inspecting engine, make sure engine has cooled down; wait approximately 30 minutes after engine
has been stopped.
lVisually inspect all belts for wear, damage or cracks on contacting surfaces and edge areas.
lMeasure deflection at the marked point ( ).
CAUTION:
lWhen checking belt deflection immediately after installation, first adjust it to the specified value.
Then, after turning crankshaft two turns or more, re-adjust to the specified value to avoid varia-
tion in deflection between pulleys.
lTighten idler pulley lock nut by hand and measure deflection without looseness.

lMeasure the valve clearance using the feeler gauge when
engine is cool (at normal temperature).
Valve clearance:
Unit: mm (in)
*: Reference data approximately 80°C(176°F)
6. Set the No. 4 cylinder at TDC by rotating the crankshaft clockwise once. (360 degrees)
7. While referring to the figure, measure the valve clearance
marked in the table below.
8. If the valve clearance is outside the specification, adjust as fol-
lows.
ADJUSTMENTS
lRemove adjusting shim for parts which are outside the specified valve clearance.
1. Extract engine oil on the upper side of the cylinder head (for the air blowing in step 6).
2. Rotate crankshaft to face the camshaft for adjusting shims that
are to be removed upward.
3. Grip camshaft with the camshaft pliers [SST], then using cam-
shaft as a support point, push adjusting shim downward to com-
press valve spring.
CAUTION:
Do not damage camshaft, cylinder head and the outer cir-
cumference of valve lifter.

12. Remove chain tensioner.
lWhen removing chain tensioner, push the plunger of chain
tensioner and keep it pressed with a push pin, etc.
13. Remove slack guide.
14. Hold fuel pump sprocket and remove bolt.
a. Insert positioning stopper pin [SST] into the hole 6 mm (0.24 in)
in the diameter on fuel pump sprocket.
b. Using the TORX wrench, turn pump shaft little by little to adjust
the position of fuel pump sprocket so that the holes align.
c. Push positioning stopper pin through fuel pump sprocket to fuel
pump body to hold fuel pump sprocket.
lInsert the positioning stopper pin until its flange contacts fuel
pump sprocket.
15. Using the hexagon wrench [SST] remove tightening bolts to fuel
pump sprocket.

lPush the plunger of the chain tensioner. While keeping
plunger pressed down with a push pin, etc., install chain
tensioner.
lAfter installation, pull out the push pin holding the plunger.
CAUTION:
Make sure again that the alignment marks on sprockets and
the colored alignment marks on timing chain are aligned.
12. Install front oil seal (1) to oil pump housing (2).
lUsing the suitable drift (A) [62 mm (2.44 in) dia.], force fit the
seal until it hits the bottom.
CAUTION:
Do not touch lips of oil seal. Make sure seal surfaces are
free of foreign materials.
13. Install vacuum pump cover to oil pump housing.
lApply a continuous bead of liquid gasket with the tube presser
[SST: WS39930000] as shown in the figure.

CYLINDER BLOCK
FLYWHEEL DEFLECTION
lMeasure the deflection of flywheel contact surface to clutch with
a dial indicator.
lMeasure the deflection at 210 mm (8.27 in) dia.
lIf measured value is out of the standard, replace flywheel.
CAUTION:
When measuring, keep magnetic fields (such as dial indicator
stand) away from signal plate of the rear end of crankshaft.
MOVEMENT AMOUNT OF FLYWHEEL
CAUTION:
Do not disassemble double mass flywheel.
Movement Amount of Thrust (Fore-and-Aft) Direction
lMeasure the movement amount of thrust (fore-and-aft) direction when 100 N (10.2 kg, 22 lb) force is
added at the portion of 125 mm (4.92 in) radius from the center of flywheel.
lIf measured value is out of the standard, replace flywheel.
Movement Amount in Radial (Rotation) Direction
Check the movement amount of radial (rotation) direction with the following procedure:
1. Install a bolt to clutch cover mounting hole, and place a torque wrench on the extended line of the flywheel
center line.
lTighten bolt at a force of 9.8 N·m (1.0 kg-m, 87 in-lb) to keep it from loosening.
2. Put a mating mark on circumferences of the two flywheel
masses without applying any load (Measurement standard
points).
3. Apply a force of 9.8 N·m (1.0 kg-m, 87 in-lb) in each direction,
and mark the movement amount on the mass on the transmis-
sion side.
4. Measure the dimensions of movement amounts “A” and “B” on
circumference of the flywheel on the transmission side.
lIf measured value is out of the standard, replace flywheel.
DRIVE PLATE
lCheck drive plate and signal plate for deformation or cracks.
CAUTION:
lDo not disassemble drive plate.
lDo not place drive plate with signal plate facing down.
lWhen handling signal plate, take care not to damage or
scratch it.
lHandle signal plate in a manner that prevents it from
becoming magnetized.
lIf anything is found, replace drive plate.Standard : 0.45 mm (0.0177 in) or less.
