GENERATOR DRIVE BELT INSPECTION
INSPECT DRIVE BELT
(a) Visually check the drive belt for excessive wear,
frayed cords etc.
If any defect has been found, replace the drive belt.
HINT: Cracks on the rib side of a drive belt are consid±
ered acceptable. If the drive belt has chunks missing
from the ribs, it should be replaced.4. INSPECT HIGH±TENSION CORD RESISTANCE
Using an ohmmeter, measure the resistance.
Maximum resistance:
25 k
per cord
If the resistance is greater than maximum, check the
terminals. If necessary, replace the high ± tension
cord.

Belt tension gauge:
Nippondenso BTG±20 (95506±00020)
Borroughs No. BT±33±73F
± 5S±FE ENGINEENGINE MECHANICALEG1±11

Drive belt tension:
w/ A/C
New belt

Used belt
130 + 10 lbf
w/o A/C
New belt
125 + 25 lbf
Used belt
95 + 20 lbf
If the belt tension is not as specified, adjust it.
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
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.
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.
± 5S±FE ENGINEENGINE MECHANICALEG1±12

4. INSPECT VALVE CLEARANCE
(a) Check only the valves indicated.
Using a thickness gauge, measure the clearance
between the valve lifter and camshaft.
Record the out± of ±specification valve clear±
ance measurements. They will be used later to
determine the required replacement adjusting
shim.
Valve clearance (Cold):
Intake
0.19 ± 0.29 mm (0.007 ± 0.011 in.)
Exhaust
0.28 ± 0.38 mm (0.011 ± 0.015 in.) 3. 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.
(b) Check that the valve lifters on the No.1 cylinder are
loose and valve lifters on the No.4 are tight.
If not, turn the crankshaft one revolution (360*) and
align the mark as above.
(b) Turn the crankshaft one revolution (360
) and align
the mark as above. (See procedure in step 3)
(c) Check only the valves indicated as shown. Measure
the valve clearance. (See procedure in step (a)) HINT: Arrange the grommets in correct order, so that
they can be reinstalled into their original positions.
This minimizes any possibility of oil leakage due to
reuse of grommets.
± 5S±FE ENGINEENGINE MECHANICALEG1±13

(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

2. CONNECT TACHOMETER AND TIMING LIGHT TO
ENGINE
Connect the test probe of a tachometer to terminal IG
(±) of the data link connector 1.
NOTICE:
wNEVER allow the tachometer terminal to touch
ground as it could result in damage to the igniter
and/or ignition coif.
wAs some tachometers are not compatible with this
Ignition system, we recommend that you confirm
the compatibility of yours before use.
3. ADJUST IGNITION TIMING
