INSPECTION
Cylinder
Inspect cylinder walls for scratches, roughness or ridges
which indicate excessive wear. If cylinder bore is very rough
or deeply scratched or ridged, rebore cylinder and use over-
size piston.

Piston clearance:
Measure cylinder bore diameter and piston diameter to find
their difference which is piston clearance. Piston clearance
should be within specification as given below. If it is out of
specification, rebore cylinder and use oversize piston.
Piston clearance
: 0.032 – 0.061 mm (0.0013 – 0.0024 in.)
: 0.016 – 0.045 mm (0.0006 – 0.0018 in.) with coating
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 clear-
ance between ring and ring land by using thickness gauge
(2). If clearance is out of limit, replace piston.
Ring groove clearance
Top ring
Standard : 0.03 – 0.07 mm (0.0012 – 0.0028 in.)
Limit : 0.12 mm (0.0047 in.)

Limit : 0.10 mm (0.0039 in.)
Oil ring
Standard : 0.03 – 0.17 mm (0.0012 – 0.0067 in.)
Piston Pin
Check piston pin, connecting rod small end bore and piston
bore for wear or damage, paying particular attention to con-
dition of small end bore bush. If pin, connecting rod small
end bore or piston bore is badly worn or damaged, replace
pin, connecting rod and/or piston. NOTE:
Cylinder bore diameters used here are measured in
thrust direction at two positions.
“a” : 19.5 mm (0.77 in.)

Piston pin clearance :
Check piston pin clearance in small end and piston. Replace
connecting rod and/or piston if its small end is badly worn or
damaged or if measured clearance exceeds limit.
Piston pin clearance in connecting rod small end
: 0.003 – 0.014 mm (0.0001 – 0.0006 in.)

Connecting Rod
Big-end side clearance:
Check big-end of connecting rod for side clearance, with rod
fitted and connected to its crank pin in the normal manner. If
measured clearance is found to exceed its limit, replace con-
necting rod.

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 bearing
and 0.25 mm (0.0098 in.) undersize bearing. For identifica-
tion 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 gaging 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) once again.

5) Remove cap and using a scale (1) on gaging plastic (2)
envelope, measure gaging plastic width at the widest point
(clearance).
If clearance exceeds its limit, use a new standard size bear-
ing and remeasure clearance.
