INSTALLATION
1) Remove oil gasket and oil on mating surfaces and install new
head gasket (1) as shown in figure, that is, “TOP” mark provided
on gasket comes to crankshaft pulley side, facing up (toward cyl-
inder head side).
2) Check to make sure that oil jet (venturi plug) is installed and if
it is, that it is not clogged.
When installing it, be sure to tighten to specified torque.

.m (0.35 kg-m, 2.5 lb-ft)
3) Apply engine oil to cylinder head bolts and tighten them gradual-
ly as follows.
a) Tighten all bolts to 35 N
.m (3.5 kg-m, 25.0 lb-ft) according to
numerical order in figure.
b) In the same manner as in a), tighten them to 55 N
.m
(5.5 kg-m, 40.0 lb-ft).
c) Loosen all bolts until tightening torque is reduced to 0 (zero)
in reverse order of tightening.
d) In the same manner as in a), tighten them to 35 N
.m
(3.5 kg-m, 25.0 lb-ft).
e) In the same manner as in a) again, tighten them to specified
torque.

REMOVAL
1) Remove cylinder head from cylinder block as previously out-
lined.
2) Drain engine oil.
3) Remove oil pan and oil pump strainer as previously outlined.
4) Mark cylinder number on all pistons, connecting rods and rod
bearing caps, using silver pencil or quick drying paint.
5) Remove rod bearing caps.
6) Install guide hose (1) over threads of rod bolts. This is to prevent
damage to bearing journal and rod bolt threads when removing
connecting rod.
7) Decarbon top of cylinder bore before removing piston from cylin-
der.
8) Push piston and connecting rod assembly out through the top of
cylinder bore.

Crank Pin and Connecting Rod Bearings
Inspect crank pin for uneven wear or damage. Measure crank pin
for out-of-round or taper with a micrometer. If crank pin is dam-
aged, or out-of-round or taper is out of limit, replace crankshaft or
regrind crank pin to undersize and use undersize bearing.
Connecting rod bearing size
Crank pin diameter
Standard41.982 – 42.000 mm
(1.6528 – 1.6535 in.)
0.25 mm (0.0098 in.)41.732 – 41.750 mm
(1.6430 – 1.6437 in.)
Out-of-round and taper limit: 0.01 mm (0.0004 in.)
Rod bearing:
Inspect bearing shells for signs of fusion, pitting, burn or flaking
and observe contact pattern. Bearing shells found in defective
condition must be replaced.
Two kinds of rod bearing are available; standard size bearing and
0.25 mm undersize bearing. To distinguish them, 0. 25 mm under-
size bearing has the stamped number (US025) on its backside as
indicated in figure, but standard size one has no number.
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 gaging plastic (1) to full width of crankpin 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 (3), as shown in figure. After applying
engine oil to rod bolts, tighten cap nuts to specified torque. DO
NOT turn crankshaft with gaging plastic installed.

INSTALLATION OR CONNECTION
1) Apply engine oil to pistons, rings, cylinder walls, connecting rod
bearings and crankpins.
NOTE:
Do not apply oil between connecting rod and bearing or be-
tween bearing cap and bearing.
2) Install guide hoses over connecting rod bolts.
These guide hoses protect crankpin and threads of rod bolt from
damage during installation of connecting rod and piston assem-
bly.
3) When installing piston and connecting rod assembly into cylin-
der bore, point arrow mark on piston head to crankshaft pulley
side.
4) Install piston and connecting rod assembly into cylinder bore.
Use special tool (Piston ring compressor) to compress rings.
Guide connecting rod into place on crankshaft.
Using a hammer handle, tap piston head to install piston into
bore. Hold ring compressor firmly against cylinder block until all
piston rings have entered cylinder bore.
Special Tool
(A): 09916-77310
5) Install bearing cap (1):
Point arrow mark (2) on cap to crankshaft pulley side (3).
Tighten cap nuts to specification.

to make sure all hoses, electric wires and cables are discon-
nected from engine and transmission.
27) Lower engine with transmission from body.
