PISTON RING SIDE CLEARANCE
Using feeler gauge, measure the side clearance between piston
ring and piston ring groove.
Unit: mm (in)
Align top ring and external surface of piston. Measure lower side
clearance of top ring with top ring pressed onto upper side of
ring groove.
If side clearance exceeds the limit, replace piston ring.
Check clearance again. If side clearance still exceeds the limit,
replace piston.
PISTON RING END GAP
Make sure that cylinder bore diameter is within the specifica-
tions. Refer to EM-250, "
PISTON TO CYLINDER BORE
CLEARANCE" .
Lubricate with new engine oil to piston and piston ring, and then
insert piston ring until middle of cylinder with piston, and mea-
sure piston ring end gap with feeler gauge.
Unit: mm (in)
If out of the limit, replace piston ring. If gap still exceeds the limit even with a new ring, re-bore cylinder
and use oversized piston and piston ring. Refer to EM-250, "

PISTON TO CYLINDER BORE CLEARANCE
Cylinder Bore Inner Diameter
Using bore gauge, measure cylinder inner diameters at six posi-
tions; top, middle, and bottom (“A”, “B”, “C”) in 2 directions (“X”,
“Y”).
If the measured value exceeds the limit, or if there are scratches
and/or seizure on the cylinder inner wall, hone or bore the inner
wall.
Oversize piston is provided. When using oversize piston, hone
the cylinder so that the clearance between piston and cylinder
satisfies the standard.
CAUTION:
If oversize piston is used, use it for all cylinders with over-
size piston rings.
Piston Skirt Diameter
Use micrometer to measure piston skirt diameter.
Calculation of Piston to Cylinder Bore Clearance
Calculate using piston skirt diameter and cylinder bore inner diameter (direction “X”, position “B”).
(Clearance) = (Cylinder bore inner diameter) − (Piston skirt diameter)
If it exceeds the limit, replace piston and piston pin assembly. Refer to EM-242, "HOW TO SELECT PIS-
TON" .

2. Install main bearing caps and tighten bolts to the specified torque. Refer to EM-235, "ASSEMBLY" . This
will prevent distortion of cylinder bores.
3. Cut cylinder bore.
NOTE:
When any cylinder needs boring, all other cylinders must also be bored.
Do not cut too much out of cylinder bore at a time. Cut only 0.05 mm (0.0020 in) or so at a time.
4. Hone cylinders to obtain the specified piston-to-cylinder bore clearance.
5. Measure finished cylinder bore for the out-of-round and taper.
NOTE:
Measurement should be done after cylinder bore cools down.
CRANKSHAFT MAIN JOURNAL DIAMETER

masses without applying any load (Measurement standard
points).
