Limit (“A” – “B”) : 0.1 mm (0.004 in.)
a) Tighten cylinder head bolts (“1” – “10”) to 20 N·m (2.0 kg-m,
14.5 lb-ft) according to numerical order as shown by using
a 12 corner socket wrenches.

(4.0 kg-m, 29.0 lb-ft).
c) Retighten all bolts 60° according to numerical order in fig-
ure.
d) Repeat Step c).
e) Tighten bolt “A” to specified torque.
Tightening torque
Cylinder head bolt for M8 (a) : 22 N·m (2.2 kg-m, 16.0 lb-ft)
Cylinder head bolts for M10
(b) : 40 N·m (4.0 kg-m, 29.0 lb-ft) and extra tightening 60°
twice
NOTE:
If cylinder head bolts are reused, check thread diameters
of them for deformation according to the following and
replace them with new ones if thread diameter difference
exceeds limit.
Measure each thread diameter of cylinder head bolt (1) at
“A” on 83.5 mm (2.81 in.) from seat side of flange bolt
and “B” on 115 mm (4.53 in.) from seat side of flange bolt
by using a micrometer (2).
Then calculate difference in diameters (“A” – “B”).
If it exceeds limit, replace with new one.

NOTE:
Be sure to tighten M8 bolt (“A”) after securing the other
bolt.

Rod bearing :
Inspect bearing shells for signs of fusion, pitting, burn or flak-
ing and observe contact pattern. Bearing shells found in
defective condition must be replaced.
Two kinds of rod bearing are available; standard size bear-
ing and 0.25 mm (0.0098 in.) undersize bearing. For identifi-
cation of undersize bearing, it is painted red at the position
as indicated in figure, undersize bearing thickness is 1.605 –
1.615 mm (0.0632 – 0.0635 in.) at the center of it.
Rod bearing clearance:
1) Before checking bearing clearance, clean bearing and crank
pin.
2) Install bearing in connecting rod and bearing cap.
3) Place a piece of gauging plastic (1) to full width of crank pin
as contacted by bearing (parallel to crankshaft), avoiding oil
hole.
4) Install rod bearing cap (1) to connecting rod.
When installing cap, be sure to point arrow mark (2) on cap
to crankshaft pulley side, as shown in figure. After applying
engine oil to rod bolts and tighten cap nuts (3) gradually as
follows.
a) Tighten all cap nuts to 15 N·m (1.5 kg-m, 11.0 lb-ft).
b) Retighten them to 45°.
c) Repeat step b).
Tightening torque
Connecting rod bearing cap nuts
(a) : 15 N·m (1.5 kg-m, 11.0 lb-ft) and extra tightening 45°
twice
5) Remove cap and using a scale (1) on gauging plastic (2)
envelope, measure gauging plastic width at the widest point
(clearance).
If clearance exceeds its limit, use a new standard size bear-
ing and remeasure clearance.
Connecting rod bearing clearance
Standard : 0.029 – 0.047 mm (0.0011 – 0.0019 in.)
Limit : 0.065 mm (0.0026 in.)

Reinstall any necessary parts which have not been rein-
stalled.
11) Refill cooling system with coolant engine with engine oil and
A/T with specified A/T fluid (vehicle with A/T).
12) Connect negative cable at battery.
13) Verify that there is no fuel leakage, coolant leakage, oil leak-
age, A/T fluid leakage (vehicle with A/T) and exhaust gas
leakage at each connection. NOTE:
