Installation
1. Install cylinder head gasket.
ICylinder head gasket to be installed is selected by its thickness
through the following procedure.
When replacing gasket only
IInstall gasket with same thickness as the one removed.
IGasket thickness is identified by the number of notches located
on rear-left side.
GradeGasket thickness*
mm (in)No. of notches
1 0.65 (0.0256) 1
2 0.70 (0.0276) 2
*: Thickness of gasket tightened with head bolts
IThe number of notches can be checked at the position shown
in the figure before cylinder head is removed. (It is necessary
to remove exhaust manifold.)
When repairing/replacing the following
IWhen the top of cylinder block or crankshaft pin/journal is
ground, or
IWhen cylinder block, piston, connecting rod, or crankshaft is
replaced
1) Move piston toward TDC.
2) Position dial indicator on cylinder block as shown in the figure,
and adjust the needle to ª0º.
3) Move dial indicator stand aside, and position the dial indicator
to the measuring point as shown in the figure.
4) Rotate crankshaft slowly, and read the value on dial indicator
at piston's maximum height.
5) Repeat above procedure at 2 positions of each cylinder (8
positions in total for 4 cylinders), and select the appropriate
gasket by comparing the maximum crown depression with the
table.

2. Install idler gear and idler shaft.
ICheck that the counter marks with cam gear, ªAAº and ªBBº, are
located on the front side of the engine.
Refer to EM-52.
CAUTION:
Since idler gear cannot be installed or removed with cylinder
head assembly mounted on the engine because of interfer-
ence with gear case, make sure that there are no reverse
installations or uninstalled parts.
3. Install cylinder head assembly.
1) Attach gasket onto the rear of gear case.
2) Install O-ring to the rear of gear case.
3) Align cylinder head assembly with dowel pin of cylinder block
and install.
CAUTION:
IMake sure the O-ring does not fall off. Be careful not to
drop the O-ring.
IDo not damage gasket located at the front.
4. Position cylinder head assembly close to the rear of the gear
case.
1) Install cylinder head bolts to the front and rear of cylinder head
respectively, and tighten to the specified torque.
:40-49N×m (4.0 - 5.0 kg-m, 29 - 36 ft-lb)
2) Loosen cylinder head bolts completely.
3) Install gear case mounting bolts to 2 positions shown by arrows
in the figure, and tighten to the specified torque.
: Less than 9.8 N×m (1.0 kg-m, 87 in-lb)
5. Tighten cylinder head bolts in the order indicated in the figure.
1) Apply engine oil to installation bolt threads and washers.
2) Tighten bolts to 98 to 102 N×m (10.0 to 10.5 kg-m, 73 to 75 ft-
lb).
3) Loosen bolts completely until the torque becomes 0 N×m(0
kg-m, 0 in-lb).
CAUTION:
For procedure 3), loosen bolts in the reverse order as indi-
cated in the figure.
4) Tighten bolts to 40 to 44 N×m (4.0 to 4.5 kg-m, 29 to 32 ft-lb).
5) Tighten bolts at the angle of 90 to 95É (target is 95É). (Angle

3) Install engine sub-attachment (SST) to the rear side of cylinder
block.
IAlign knock pin on cylinder block with pin hole on attachment
to install engine sub-attachment.
IMounting bolts are provided with engine sub-attachment.
4) Install engine attachment (SST).
IUse commercially available M12 mounting bolts and nuts (4
sets) with strength grade of 9T (minimum).
5) Hoist engine and install it to the engine stand (SST).
IEngine attachment and engine sub-attachment can be installed
to engine stand before engine installation.
4. Drain engine oil and coolant from engine.
5. Remove the following parts and related parts. (Only major parts
are listed.)
IAccessory belt
ICatalytic converter
