Inspect piston ring groove clearance
Using a feeler gauge, measure the clearance between
new piston ring and the wall of the ring groove.
Ring groove clearance:
No.1
0.040 — 0.080 mm (0.0016 — 0.0031 in.)
No.2
0.030 — 0.070 mm (0.0012 — 0.0028 in.) EG
If the clearance is greater than maximum, replace the
piston.
Inspect piston ring end gap
Insert the piston ring into the cylinder bore.
Using a piston, push the piston ring a little beyond the
bottom of the ring travel, IIO mm (4.33 in.) from the
top of the cylinder block.
Using a feeler gauge, measure the end gap.
Standard and gap:
No.1
0.330 — 0.550 mm (0.0130 — 0.0217 in.)
No.2
0.450 —- 0.670 mm (0.0177 — 0.0264 in.)
Oil (Side rail)
0.150 — 0.500 mm (0.0059 - 0.0197 in.)
Maximum end gap:
No.1
0.85 mm (0.0335 in.)
No.2
0.97 mm (0.0382 in.)
Oil (Side rail)
0.80 mm (0.03'I5 in.)
If the end gap is greater than maximum, replace the
piston ring. If the end gap is greater than maximum,
even with a new piston ring, replace the cylinder
block.
Inspect piston pin fit
At 60°C (I40°F), you should be able to push the
piston pin into the piston pin hole with your thumb.
