6. Suspend engine with a hoist, and support the engine posture.
For installation of engine slingers, refer to EM-69, "
ENGINE ASSEMBLY" .
7. Remove RH engine mount insulator.
8. Remove center member and rear engine mounting bracket.
9. Drain engine oil.
10. Remove oil pan upper and lower, and oil strainer. Refer to EM-26, "
OIL PAN AND OIL STRAINER" .
11. Remove intake valve timing control cover.

b. Remove the cover using Tool (Seal cutter).
CAUTION:
Be careful not to damage mounting surface.
12. Pull chain guide between camshaft sprockets out through front
cover.
13. Set No. 1 cylinder at TDC on its compression stroke with the fol-
lowing procedure.

CYLINDER HEAD
●If the engine speed is out of specified range, check battery liquid for proper gravity. Check engine
speed again with normal battery gravity.
●If compression pressure is below minimum value, check valve clearances and parts associated with
combustion chamber (Valve, valve seat, piston, piston ring, cylinder bore, cylinder head, cylinder head
gasket). After the checking, measure compression pressure again.
●If 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
malfunctioning. Check the valves for damage. Replace the valve or valve seat accordingly.
●If 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 BeltsEBS00LRA
●Before inspecting the engine, make sure the engine has cooled
down; wait approximately 30 minutes after the engine has been
stopped.
●Visually inspect all belts for wear, damage or cracks on contact-
ing surfaces and edge areas.
●When measuring deflection, apply 98 N (10 kg, 22 lb) at the
marked point ( ).
CAUTION:
●When 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.
●Tighten idler pulley lock nut by hand and measure deflection without looseness.
Belt Deflection:
*: When engine is cold.
Tension AdjustmentEBS00LRB
●Adjust belts with the parts shown below.
CAUTION:
●When a new belt is installed as a replacement, adjust it to the value specified under “New” value
because of insufficient adaptability with pulley grooves.
●If the belt deflection of the current belt is out of the “Limit for re-adjusting”, adjust to the
“Adjusted” value.
●When 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.
●Make sure the belts are fully fitted into the pulley grooves during installation.
●Handle with care to avoid smearing the belts with engine oil or cooling water etc.
●Do not twist or bend the belts with strong force.
