INSPECTION
1. INSPECT TIMING BELT
NOTICE:

Do not bend, twist or turn the timing belt inside out.

Do not allow the timing belt to come into contact with
oil, water or steam.

Do not utilize timing belt tension when installing or re-
moving the mount bolt of the camshaft timing pulley.
If there is any defect, as shown in the illustration, check these
points:
(a) Premature parting

Check for proper installation.

Check the timing cover gasket for damage and
proper installation.
(b) If the belt teeth are cracked or damaged, check to see if
either camshaft is locked.
(c) If there is noticeable wear or cracks on the belt face,
check to see if there are nicks on the side of the idler
pulley lock and water pump.
(d) If there is wear or damage on even one side of the belt,
check the belt guide and the alignment of each pulley.
(e) If there is noticeable wear on the belt teeth, check timing
cover for damage and for foreign material on the pulley
teeth.
If necessary, replace the timing belt.
2. INSPECT IDLER PULLEYS
(a) Visually check the seal portion of the idler pulley for oil
leakage.
If leakage is found, replace the idler pulley.
(b) Check that the idler pulley turns smoothly.
If necessary, replace the idler pulley.
3. INSPECT TIMING BELT TENSIONER
(a) Visually check the seal portion of the tensioner for oil leak-
age.
HINT:
If there is only the faintest trace of oil on the seal on the push
rod side, the tensioner is all right.
If leakage is found, replace the tensioner.

INSTALLATION
1. INSTALL CRANKSHAFT TIMING PULLEY
(a) Align the timing pulley set key with the key groove of the
pulley.
(b) Using SST and a hammer, tap in the timing pulley, facing
the flange side inward.
SST 09223±46011
2. INSTALL NO.1 IDLER PULLEY AND NO.2 IDLER
PULLEY
(a) Apply adhesive 2 or 3 threads of the pivot bolt.
Adhesive:
Part No. 08833±00080, THREE BOND 1344,
LOCTITE 242 or equivalent

INSPECTION
1. CLEAN TOP SURFACES OF PISTONS AND CYL-
INDER BLOCK
(a) Turn the crankshaft, and bring each piston to top dead
center (TDC). Using a gasket scraper, remove all the car-
bon from the piston top surface.
(b) Using a surface contacting gasket scraper, remove all the
gasket materials from the cylinder block.
(c) Using compressed air, blow carbon and oil from the bolt
holes.
CAUTION:
Protect your eyes when using high pressure compressed
air.
2. REMOVE GASKET MATERIAL
Using a gasket scraper, remove all the gasket material from the
cylinder block contact surface.
NOTICE:
Be careful not to scratch the surface contacting the cylin-
der block.
3. CLEAN COMBUSTION CHAMBERS
Using a wire brush, remove all the carbon from the combustion
chambers.
NOTICE:
Be careful not to scratch the surface contacting the cylin-
der block.
4. CLEAN VALVE GUIDE BUSHINGS
Using a valve guide bushing brush and solvent, clean all the
guide bushings.

9. CLEAN VALVES
(a) Using a gasket scraper, chip off any carbon from the valve
head.
(b) Using a wire brush, thoroughly clean the valve.
10. INSPECT VALVE STEMS AND GUIDE BUSHINGS
(a) Using a caliper gauge, measure the inside diameter of the
guide bushing.
Bushing inside diameter:
5.510 to 5.530 mm (0.2169 to 0.2177 in.)
(b) Using a micrometer, measure the diameter of the valve
stem.
Valve stem diameter:
Intake5.470 to 5.485 mm (0.2154 to 0.2159 in.)
Exhaust5.465 to 5.480 mm (0.2152 to 0.2157 in.)
(c) Subtract the valve stem diameter measurement from the
guide bushing inside diameter measurement.
Standard oil clearance:
Intake0.025 to 0.060 mm (0.0010 to 0.0024 in.)
Exhaust0.030 to 0.065 mm (0.0012 to 0.0026 in.)
Maximum oil clearance:
Intake0.08 mm (0.0031 in.)
Exhaust0.10 mm (0.0039 in.)
If the clearance is greater than maximum, replace the valve and
guide bushing. (See page EM±56)
11. INSPECT AND GRIND VALVES
(a) Grind the valve enough to remove pits and carbon.
(b) Check that the valve is ground to the correct valve face
angle.
Valve face angle: 44.5°
