Removal1) Remove engine assembly from vehicle referring to “Engine Assembly Removal and Installation”.
2) Remove cylinder head referring to “Valves and Cylinder Head Removal and Installation”.
3) Mark cylinder number on all pistons, connecting rods
and connecting rod caps using silver pencil or quick
drying paint.
4) Remove rod bearing caps.
5) Decarbonize top of cylinder bore before removing piston from cylinder.
6) Push piston and connecting rod assembly out through the top of cylinder bore.
Installation 1) Apply engine oil to pistons, rings, cylinder walls, connecting rod bearings and crank pins.
NOTE
Do not apply oil between connecting rod and
bearing or between bearing cap and bearing.
2) When installing piston and connecting rod assembly into cylinder bore, point front mark or arrow mark (1)
on piston head to crankshaft pulley side. 3) 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.

Connecting Rod Bearing Clearance1) 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 bearing cap bolts (3),
tighten bearing cap bolts (3) gradually as follows.
a) Tighten all bearing cap bolts to 15 N ⋅m (1.5 kgf-
m, 11.0 lb-ft)
b) Retighten them to 45°
c) Repeat Step b) once again.
Tightening torque
Connecting rod bearing cap bolt: 15 N ⋅m (1.5

turning through 45 ° twice 5) Remove cap and using a scale (1) on gauging
plastic envelope (2), measure gauging plastic (2)
width at the widest point (clearance).
If clearance exceed its limit, use a new standard size
bearing referring to “Selection of Connecting Rod
Bearings: ”.
After selecting new bearing, recheck clearance.
Connecting rod bearing clearance
Standard: 0.029 – 0.047 mm (0.0011 – 0.0018 in.)
Limit: 0.065 mm (0.0026 in.)
6) If clearance can not be brought to its limit even by using a new standard size bearing, use next thicker
bearing and recheck clearance or regrind crank pin
to undersize and use 0.25 mm undersize bearing.
Selection of Connecting Rod Bearings
NOTE
• If bearing is in malcondition, or bearing clearance is out of specification, select a
new standard bearing according to the
following procedure and install it.
• When replacing crankshaft or connecting rod and its bearing due to any reason,
select new standard bearings to be
installed by referring to numbers stamped
on connecting rod and its cap and/or
alphabets stamped on crank web of No.3
cylinder.
1) Check stamped numbers on connecting rod and its cap as shown.
Three kinds of numbers (“1”, “2” and “3”) represent
the following connecting rod big end inside
diameters.
For example, stamped number “1” indicates that
corresponding connecting rod big end inside
diameter is 45.000 – 45.006 mm (1.7717 – 1.7718
in.).

2) Next, check crankshaft pin diameter. On crank web No.3, four alphabets are stamped as shown in the
figure.
Three kinds of alphabet (“A”, “B” and “C”) represent
the following crankshaft pin diameter respectively.
For example, stamped “A” indicates that
corresponding crankshaft pin diameter is 41.994 –
42.000 mm (1.6533 – 1.6534 in.).
Crankshaft pin outer diameter
3) There are five kinds of standard bearings differing in thickness. To distinguish them, they are painted in
the following colors at the position as indicated in the
figure.
Each color indicated the following thickness at the
center of bearing.

4) From number stamped on connecting rod and its cap and alphabets stamped on crank web No.3,
determine new standard bearing to be installed to
connecting rod big end inside, by referring to the
table.
For example, if number stamped on connecting rod
and its cap is “1” and alphabet stamped on crank
web No.3 is “B”, install a new standard bearing
painted in “Black” to its connecting rod big end
inside.

what is found through visual check of components parts
after disassembly, prepare replacing parts and proceed
to reassembly.
Make sure that wheel side joint assembly and DOJ
housing are washed thoroughly and air dried.
Replace boot(s) with new one(s).
CAUTION!
• Do not wash boots in degreaser such as gasoline or kerosene. etc. Washing in
degreaser causes deterioration of boot.
• To ensure full performance of joint as designed, be sure to distinguish between
two types of grease in repair set and apply
specified volume to respective joint
referring to the followings for identification
of the grease.
