lIf some cylinders have low compression pressure, pour small amount of engine oil into the spark plug hole
of the cylinder to re-check it for compression.
–If the added engine oil improves the compression, the piston rings may be worn out or damaged. Check
the piston rings and replace if necessary.
–If the compression pressure remains at low level despite the addition of engine oil, the valves may be mal-
functioning. Check the valves for damage. Replace the valve or valve seat accordingly.
lIf two adjacent cylinders have respectively low compression pressure and their compression remains low
even after the addition of engine oil, the gaskets are leaking. In such a case, replace the cylinder head
gaskets.
8. Install spark plug, ignition coil and harness connectors.

Checking Drive BeltsEBS00BNX
lBefore inspecting the engine, make sure the engine has cooled
down; wait approximately 30 minutes after the engine has been
stopped.
lVisually inspect all belts for wear, damage or cracks on contact-
ing surfaces and edge areas.
lWhen measuring deflection, apply 98 N (10 kg, 22 lb) at the
marked point ( ).
CAUTION:
lWhen checking belt deflection immediately after installa-
tion, first adjust it to the specified value. Then, after turn-
ing the crankshaft two turns or more, re-adjust to the
specified value to avoid variation in deflection between
pulleys.
lTighten idler pulley lock nut by hand and measure deflection without looseness.
Belt Deflection:
*: When engine is cold.
Tension AdjustmentEBS00BNY
lAdjust belts with the parts shown below.
CAUTION:
lWhen a new belt is installed as a replacement, adjust it to the value specified under “New” value
because of insufficient adaptability with pulley grooves.
lIf the belt deflection of the current belt is out of the “Limit for re-adjusting”, adjust to the
“Adjusted” value.
lWhen checking belt deflection immediately after installation, first adjust it to the specified value.
Then, after turning crankshaft two turns or more, re-adjust it to the specified value to avoid vari-
ation in deflection between pulleys.
lMake sure the belts are fully fitted into the pulley grooves during installation.
lHandle with care to avoid smearing the belts with oil or cooling water etc.
lDo not twist or bend the belts with strong force.
