HINT:
wªNew beltº refers to a belt which has been used
less than 5 minutes on a running engine.
wªUsed beltº refers to a belt which has been used
on a running engine for 5 minutes or more.
wAfter installing a belt, check that it fits properly in
the ribbed grooves.
wCheck with your hand to confirm that the belt has
not slipped out of the groove on the bottom of
the pulley.
wAfter installing a new belt, run the engine for
about 5 minutes and recheck the belt tension.
VALVE CLEARANCE INSPECTION AND
ADJUSTMENT
HINT: Inspect and adjust the valve clearance when
the engine is cold.
1. DISCONNECT HIGH ± TENSION CORDS FROM
SPARK PLUGS

boot. DO NOT pull on the cords.
NOTICE: Pulling on or bending the cords may damage the
conductor inside.
2. REMOVE CYLINDER HEAD COVER
(a) Disconnect the PCV hoses.
(b) Loosen the 2 wire harness clamp bolts (No.2 timing
belt cover) mounting bolts.
(c) Remove the 4 nuts, grommets, head cover and gasket.

(c) Install the gasket to the head cover.
(d) Install the head cover with the 4 grommets and nuts.
Uniformly tighten the nuts in several passes.
Torque: 23 N±m (230 kgf±cm. 17 ft±lbf)
HINT: Install the grommets so that their markings are
as shown in the illustration.
(e) Tighten the 2 wire harness clamp (No.2 timing belt
cover) mounting bolts.
(f) Connect the PCV hoses.
7. RECONNECT HIGH±TENSION CORDS TO SPARK
PLUGS(c) Install a new adjusting shim.
wPlace a new adjusting shim on the valve lifter.
wUsing SST (A), press down the valve lifter and
remove SST (B).
SST 09248±50020 (09248±05011, 09248±05021)
(d) Recheck the valve clearance.
6. REINSTALL CYLINDER HEAD COVER
(a) Remove any old packing (FIPG) material.
(b) Apply seal packing to the cylinder head as shown in
the illustration.
Seal pecking:
Part No.08826±00080 or equivalent

(e) If the cylinder compression in one or more cylinders is
low, pour a small amount of engine oil into the cylin±
der through the spark plug hole and repeat steps (a)
through
(c) for cylinders with low compression.
wIf adding oil helps the compression, chances are
that the piston rings and/or cylinder bore are
worn or damaged.
wIf pressure stays low, a valve may be sticking or
seating is improper, or there may be leakage past
the gasket.
6. REINSTALL SPARK PLUGS
Using a 16 mm plug wrench, install the spark plug.
Torque: 18 N±m (180 kgf±cm, 13 ft±lbf)

TIMING BELT REMOVAL
(See Components for Removal and Installation)
1. DISCONNECT NEGATIVE (±) TERMINAL CABLE
FROM BATTERY
CAUTION: Work must be started after 90 seconds from
the time the ignition switch is turned to the 'LOCK'
position and the negative (±) terminal cable is discon±
nected from the battery.
2. REMOVE ENGINE COOLANT RESERVOIR TANK
(a) Disconnect the reservoir hose.
(b) While pushing the tab of the bracket, remove the
reservoir tank.
3. REMOVE GENERATOR (See page CH±10)
4. REMOVE RH FRONT WHEEL
5. REMOVE RH FENDER APRON SEAL
8. REMOVE ENGINE MOVING CONTROL ROD
Remove the 3 bolts and control rod.
9. DISCONNECT CONNECTOR FROM GROUND WIRE
ON RH FENDER APRON7. SLIGHTLY JACK UP ENGINE
Raise the engine enough to remove the weight from
the engine mounting on the right side. 6. REMOVE PS DRIVE BELT
Loosen the 2 bolts, and remove the drive belt.

11. REMOVE SPARK PLUGS
(a) Disconnect the high ± tension cords at the rubber
boot.
DO NOT pull on the cords.
NOTICE: Pulling on or bending the cords may damage the
conductor inside.
13. SET NO.1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley and align its groove with
timing mark ª0º of the No.1 timing belt cover. 12. REMOVE NO.2 TIMING BELT COVER
Remove the 5 bolts, timing belt cover and 2 gaskets.10. REMOVE No.2 ENGINE MOUNTING BRACKET
Remove the 3 bolts and mounting bracket.
(b) Using a 16 mm plug wrench, remove the spark plug.

14. REMOVE TIMING BELT FROM CAMSHAFT TIMING
PULLEY
HINT (When re±using timing belt): Place the match±
marks on the timing belt and camshaft timing pulley,
and place matchmark on timing belt to match the end
of the No.1 timing belt cover.
15. REMOVE CAMSHAFT TIMING PULLEY
Using SST, remove the bolt, plate washer and timing
pulley.
SST 09249±63010 and 09278±54012(b) Check that the hole of the camshaft timing pulley is
aligned with the timing mark of the bearing cap.
If not, turn the crankshaft one revolution (360'*).
(a) Loosen the mounting bolt of the No.1 idler pulley and
shift the pulley toward the left as far as it will go, and
temporarily tighten it.
(b) Remove the timing belt from the camshaft timing
pulley.

wDo not utilize timing belt tension when installing or
removing the mounting bolt of the camshaft timing
pulley.
If there are any defects as shown in the illustration,
check the following points:
(a) Premature parting
wCheck for proper installation.
wCheck the timing cover gasket for damage and
proper installation.
(b) If the belt teeth are cracked or damaged, check to see
if either camshaft or water pump is locked.
(e) If there is noticeable wear on the belt teeth, check the
timing cover for damage, correct gasket installation,
and for foreign material on the pulley teeth.
If necessary, replace the timing belt. (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.
(d) If there is wear or damage on only one side of the belt,
check the belt guide and the alignment of each pulley.

tions, and align its groove with the mark at 45 BTDC
(for No.1 cylinder) of the No.1 timing belt cover.
NOTICE: Always turn the crankshaft clockwise.
(c) Check that each pulley aligns with the timing marks as
shown in the illustration..
If the timing marks do not align, remove the timing
