1.Measure the clearance
between the piston ring and the ring groove. If the measured
value
exceeds the limit, replace the piston ring, or both the
piston and the piston ring. Standard value:
No. 1 ring: 0.03 - 0.07 mm No. 2
ring: 0.02 - 0.06 mm
Limit: 0.1
mm

2.Insert the piston ring
into the cylinder bore. Insert the piston with the top face
end
first into the cylinder bore, pushing the piston ring and
positioning it squarely with the cylinder
bore. Then, measure the piston ring end gap using a feeler
gauge. If the measured value exceeds
the limit, replace the piston ring. Standard
value:
No. 1 ring: 0.15 - 0.30
mm No. 2 ring: 0.20 - 0.40 mm Oil ring:
0.10 - 0.35 mm
Limit:
No. 1 ring: 0.8 mm No. 2 ring: 0.8
mm Oil ring: 1.0 mm

2.Place a plastigage, with a
length equal to the bearing width, onto the crank pin in the
axial direction. 3.Carefully install the
connecting rod cap over the plastigage, and tighten the
bolts
to the specified torque of 14.7 ± 2.0
N·m. 4.Next, tighten the bolts 90° to
94°. 5.Remove the bolts. Slowly remove the
connecting rod cap.

6.Using the measure printed
on the plastigage package, measure the width (widest
portion)
of the crushed plastigage. Standard value:
0.026 - 0.062 mm Limit: 0.1 mm
