12. INSPECT VALVE CLEARANCE
HINT:
Inspect and adjust the valve clearance when the engine is cold.
(a) Check only the valve indicated in the illustration.(1) Using a feeler gauge, measure the clearance be-tween the valve lifter and the camshaft.
(2) Record the out±of specification valve clearance measurements. They will be used later to determine
the required replacement adjusting shim.
Valve clearance (Cold):
Intake 0.19 to 0.29 mm (0.0075 to 0.0114 in.)
Exhaust 0.30 to 0.40 mm (0.0118 to 0.0157 in.)
(b) Turn the crankshaft clockwise 1 revolution (360
) and set
No. 4 cylinder to TDC/compression.

EXAMPLE: (Intake)
Measure valve clearance = 0.44 mm (0.0173 in.)
0.44 mm (0.0173 in.) ± 0.24 mm (0.0094 in.) = 0.20 mm (0.0079 in\
.)
(Measured ± Specification = Excess clearance)
Used shim measurement = 5.30 mm (0.2087 in.)
0.20 mm (0.0079 in.) + 5.30 mm (0.2087 in.) = 5.50 mm (0.2165 in.)\

(Excess clearance + Used shim = Ideal new shim)
Closest new shim = 5.50 mm (0.2165 in.) = Shim No. º50º

(f) Using a micrometer, measure the thickness of the re-
moved lifter.
(g) Calculate the thickness of a new lifter so that the valve clearance comes within the specified valve.

40. SET NO. 1 CYLINDER TO TDC/COMPRESSION
(a) Using the crankshaft pulley bolt, turn the crankshaft to set
the dot mark of the crankshaft timing pulley at the position
of 90
BTDC.
NOTICE:
If the timing belt is disengaged, having the crankshaft tim-
ing pulley at wrong angle can cause the piston head and
valve head to come into contact with each other.
41. INSTALL CAMSHAFT
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be kept level while it is being installed. If the
camshaft is not kept level, damage to the cylinder head or
the camshaft may result. To avoid this, the following proce-
dures should be carried out.
(a) Place the camshaft carrier on the cylinder head.
(b) Install the camshaft sub±assy No. 1.
(c) Apply engine oil to the cam and gear of the camshaft, and
the journal of the camshaft carrier.
(d) Place the intake camshaft on the camshaft carrier as
shown in the illustration so that the No. 3 and No. 4 of cyl-
inder cam lobes face downward.
42. INSTALL NO.2 CAMSHAFT
(a) Install the camshaft sub±assy No. 2.
(b) Apply engine oil to the cam and gear of the camshaft, and
the journal of the camshaft carrier.
(c) Engage the exhaust camshaft gear and the intake cam-
shaft gear by aligning the alignment marks on each gear.
(d) Roll down the exhaust camshaft onto the bearing journals
while engaging gears with each other.

20. REMOVE TIMING BELT
HINT:
If re±use the timing belt, draw an arrow on the belt which indi-
cates the engine revolution direction and put match marks on
the pulleys and the belt before removing. This operation will be
very helpful when re±installing the timing belt.
(a) Alternately loosen the 2 bolts to remove the timing belt
tensioner.
(b) Remove the timing belt.
21. SET NO. 1 CYLINDER TO TDC/COMPRESSION
(a) Using SST, set the pulleys of the camshaft and the injec-
tion pump so that each timing mark of the pulleys is
aligned with its timing mark on the cylinder head assem-
bly and the water pump assembly.
SST 09960±10010 (09962±01000, 09963±01000)
(b) Using the crankshaft pulley bolt, align the dot mark of the
crankshaft timing pulley with the TDC mark of the oil pump
by turning the crankshaft.
NOTICE:
Take great care, when turning the camshaft and crank-
shaft. Since the valve head and the piston head are sensi-
tive, damage to them may result when the piston head con-
tacts with the valve heads.
22. INSTALL TIMING BELT
NOTICE:
The engine should be cold.
(a) Remove any oil or water on each pulley and keep them
clean.
NOTICE:
Do not use any cleaning agent.
