4A–FE engine is an in–line, 4–cylinder, 1.6 liter DOHC 16–valve engine. Manual — part 3
(b) Determine the replacement adjusting shim size by
following the Formula or Charts:
•
Using a micrometer, measure the thickness of the
removed shim.
•
Calculate the thickness of a new shim so that the
valve clearance comes within the specified value.
T . . .. Thickness of used shim
A . . .. Measured valve clearance
N . . .. Thickness of new shim
Intake N = T + (A – 0.20 mm (0.008 in.))
Exhaust N = T + (A – 0.33 mm (0.013 in.))
•
Select a new shim with a thickness as close as
possible to the calculated value.
HINT: Shims are available in seventeen sizes in increments
of 0.05 mm (0.0020 in.), from 2.50 mm (0.0984 in.)
to 3.30 mm (0.1299 in.)
9. ADJUST VALVE CLEARANCE
(a) Remove the adjusting shim.
•
Turn the crankshaft to position the cam lobe of
the camshaft on the adjusting valve upward.
•
Position the notch of the valve lifter facing the
spark plug side.
•
Using SST (A), press down the valve lifter and
place SST (B) between the camshaft and valve
lifter. Remove SST (A).
SST 09248–55020 (09248–05011 (A), 09248–05021 (B))
HINT: Apply SST (B) at a slight angle on the side
marked with ”7”, at the position shown in the illustration.
•
Remove the adjusting shim with
small screwdriver and magnetic fin-
ger.

Intake valve clearance (Cold): 0.15 – 0.25 mm (0.006 – 0.010 in.)
EXAMPLE: The 2.800 mm (0.1 102 in.) shim is installed, and the
measured clearance is 0.450 mm (0.0177 in.). Replace the 2.800 mm
(0.1 102 in.) shim with a new No. 12 shim.

INSPECTION AND ADJUSTMENT OF
VALVE
CLEARANCE (5S–FE)
HINT: Inspect and adjust the valve clearance when the
engine is cold.
1. REMOVE ACCELERATOR BRACKET
2. DISCONNECT HIGH–TENSION CORDS FROM SPARK
PLUGS
3. DISCONNECT ENGINE WIRE PROTECTOR BETWEEN
CYLINDER HEAD COVER AND NO.3 TIMING BELT
COVER
4. REMOVE CYLINDER HEAD COVER
(See step 33 on page
EM–156
)
5. SET NO.1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley and align its groove with
timing mark ”0” 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
В°
) and
align
the mark as above.
6. INSPECT VALVE CLEARANCE
(a) Check only the valves indicated.
•
Using a feeler 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 deter-
mine 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.)
(b) Turn the crankshaft one revolution (360
В°
) 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))
7. ADJUST VALVE CLEARANCE
(a) Remove the adjusting shim.
•
Turn the crankshaft to position the cam lobe of
the camshaft on the adjusting valve upward.
Position the notch of the valve lifter facing the
spark plug side.
