Cylinder
Visual inspection
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.
Cylinder bore diameter, taper and out-of-round
Using a cylinder gauge (1), measure cylinder bore in
thrust and axial directions at two positions (“a” and “b”)
as shown in figure.
If any of the following conditions is noted, rebore
cylinder.
1) Cylinder bore dia. exceeds limit.
2) Difference of measurements at two positions
exceeds taper limit.
3) Difference between thrust and axial measurements
exceeds out-of-round limit.
Cylinder bore diameter

NOTE
If any one of four cylinders has to be rebored,
rebore all four to the same next oversize.
This is necessary for the sake of uniformity
and balance.

Piston
Visual inspection
Inspect piston for faults, cracks or other damages.
Damaged or faulty piston should be replaced.
Piston diameter
As indicated in figure, piston diameter should be
measured at a position 19.5 mm (0.77 in.) (“a”) from
piston skirt end in the direction perpendicular to piston
pin.

Piston clearance
Measure cylinder bore diameter and piston diameter to
find their difference which is piston clearance. Piston
clearance should be within specification 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.

Connecting Rod Bearing General Information
Service connecting rod bearings are available in
standard size and 0.25 mm (0.0098 in.) undersize
bearing, and standard size bearing has 5 kinds of
bearings differing in tolerance.
For identification 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.
Connecting Rod Bearing Visual Inspection
Inspect bearing shells for signs of fusion, pitting, burn or
flaking and observe contact pattern. Bearing shells
found in defective condition must be replaced.
Connecting 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, tighten cap nuts
(3) gradually as follows.
a) Tighten all cap nuts 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 nut (a): Tighten
15 N⋅m (1.5 kgf-m, 11.0 lb-ft) 45° and 45° by
the specified procedure
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.
