Disassembly1) Using piston ring expander, remove two compression rings (Top and 2nd) and oil ring from
piston.
2) Remove piston pin from connecting rod as follows. a) Ease out piston pin circlip (1), as shown.
b) Force piston pin out.
Assembly 1) Decarbonize piston head and ring grooves using a suitable tool.
2) Install piston pin to piston (1) and connecting rod (2): a) After applying engine oil to piston pin and piston pin holes in piston and connecting rod.
b) Fit connecting rod as shown in figure.
NOTE
Be sure to position front mark or arrow mark
(4) on piston and oil hole (5) of connecting
rod at specified position as shown in figure.

c) Insert piston pin to piston and connecting rod.
d) Install piston pin circlips (3).
NOTE
Circlip should be installed with its cut part
facing as shown in figure. Install so that
circlip end gap comes within such range as
indicated by arrow.

3) Install piston rings to piston:
• As indicated in the figure, 1st and 2nd rings have discrimination mark (4) respectively. When
installing these piston rings to piston, direct
marked side of each ring toward top of piston.
• 1st ring (1) differs from 2nd ring (2) in thickness, shape and color of surface contacting cylinder
wall.
Distinguish 1st ring from 2nd ring by referring to
the figure.
• When installing oil ring (3), install spacer first and then two rails.
4) After installing three rings (1st, 2nd and oil rings), distribute their end gaps as shown in figure.

Piston clearance
Measure cylinder bore diameter and piston diameter to
find their difference which is piston clearance. Piston
clearance should be within spec ification as follows. If it is
out of specification, rebore cylinder and use oversize
piston.
NOTE
Cylinder bore diameters used here are
measured in thrust direction at two positions.

Piston clearance
Standard (used piston): 0.032 – 0.061 mm (0.0013 –
0.0024 in.)
Standard (new piston with coating): 0.010 – 0.051
mm (0.0004 – 0.0020 in.)
Limit: 0.161 mm (0.0063 in.)
Ring groove clearance
Before checking, piston grooves must be clean, dry and
free of carbon deposits.
Fit new piston ring (1) into piston groove, and measure
clearance between ring and ring land by using thickness
gauge (2). If clearance is ou t of specification, replace
piston.
Ring groove clearance
Piston Ring
Piston ring end gap
To measure end gap, insert piston ring (2) into cylinder
bore and then measure the gap by using thickness
gauge (1).
If measured gap exceeds limit, replace ring.
NOTE
Decarbonize and clean top of cylinder bore
before inserting piston ring.

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.).
