Under Size Bearing Usage
●
If bearing clearance is out of specifications for connecting rod bearings in standard size, use under size
bearings.
●
When using under size bearings, measure bearing inner diameter with bearing installed, and grind crank-
shaft pins to adjust clearance to specification.

Unit: mm (in)
CAUTION:
When grinding the crankshaft journal to use an under size bear-
ing, avoid damaging the fillet R.
HOW TO SELECT MAIN BEARING
When Using a New Cylinder Block and Crankshaft
1.
Identify the bearing housing grade (No. 0, 1, or 2) on LH surface
at the rear of the cylinder block, and locate the applicable grade
on the “Grade” row in the table below.
2.
Identify the journal grade (No. 0, 1, or 2) on the front surface of
the crankshaft, and locate the applicable grade under the
“Grade” column on the table.
3.
The main bearing to be used (STD 0 to STD 4) can be located
in the cell where the row and column cross.
When Re-using Removed Cylinder Block and Crankshaft
1.
Measure the inner diameter of cylinder block main bearing hous-
ing.
2.
Locate the applicable cell where the measurement falls, on
“Inner diameter of cylinder block main bearing housing” row on
the table.
3.
Measure the outer diameter of the crankshaft journal.
4.
Locate the applicable cell where the measurement falls, under
“Crankshaft journal outer diameter” column on the table.
5.
The main bearing to be used (STD 0 to STD 4) can be located in
the cell where the row and column cross.

CRANKSHAFT SIDE CLEARANCE
●
Using dial indicator, measure crankshaft travel amount by mov-
ing the crankshaft forward or backward.
●
If the value exceeds the limit, replace thrust bearings with new
ones and measure again.
If the measurement exceeds the limit again, replace crankshaft
with a new one.

CONNECTING ROD SIDE CLEARANCE
●
Using feeler gauge, measure side clearance between connect-
ing rod and crankshaft arm.
●
If measured value exceeds the limit, replace connecting rod and
repeat measurement.
If measured value still exceeds the limit, replace crankshaft.
PISTON TO PISTON PIN CLEARANCE
Piston Pin Hole Inner Diameter
Using inside micrometer, measure piston pin hole inner diameter.
Piston Pin Outer Diameter
Using micrometer, measure piston pin outer diameter.
Calculation of Piston to Piston Pin Clearance
(Piston pin clearance) = (Piston pin hole inner diameter)
−
(Piston pin outer diameter)
●
If clearance is exceeds specification, replace either or both piston/piston pin assembly.
PISTON RING SIDE CLEARANCE
●
Using feeler gauge, measure clearance between piston ring and
piston ring groove.

●
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
●
Check that cylinder bore diameter is within specifications.
Refer to
EM-217, "PISTON TO CYLINDER BORE CLEAR-
.
●
Using piston, press piston ring to cylinder mid point, and mea-
sure end gap.
