arm when crankshaft is moved fully forward or backward with a dial
indicator (A).
 If the measured value exceeds the limit, replace thrust bearings,
and measure again. If it still exceeds the limit, replace crankshaft
also.
CONNECTING ROD SIDE CLEARANCE

shaft arm with a feeler gauge (A).

necting rod bearing.
CYLINDER BLOCK TOP SURFACE DISTORTION
 Using a scraper, remove gasket on the cylinder block surface, and also remove engine oil, scale, carbon, or
other contamination.
CAUTION:
Be careful not to allow gasket flakes to enter engine oil or engine coolant passages.
 Measure the distortion on the cylinder block upper face at some
different points in six directions with a straight edge and a feeler
gauge.
 If it exceeds the limit, replace cylinder block.
MAIN BEARING HOUSING INNER DIAMETER
 Install main bearing cap without main bearings installed, and tighten main bearing cap bolts to the specified
torque. Refer to EM-101, "
Disassembly and Assembly".
 Measure the position shown in the figure [5 mm (0.196 in) rear-
ward from main bearing housing front side end surface) in the 2
directions as shown in the figure. The smaller one is the measured
value.
 If out of the standard, replace cylinder block and main bearing
caps as an assembly.

Cylinder Bore Inner Diameter
 Using a bore gauge, measure the cylinder bore for wear, out-of-
round and taper at six different points on each cylinder. (“X” and
“Y” directions at “A”, “B” and “C”) (“Y” is in longitudinal direction of
the engine)
NOTE:
When determining cylinder bore grade, measure cylinder bore at
“B” position.
 If the measured value exceeds the limit, or if there are scratches and/or seizure on the cylinder inner wall,
replace cylinder block.
NOTE:
There is no service setting for oversized piston.
Piston Skirt Diameter
Measure the outer diameter of piston skirt with a micrometer.
Piston to Cylinder Bore Clearance
Calculate by piston skirt diameter and cylinder bore inner diameter (direction “X”, position “B”).

CRANKSHAFT PIN JOURNAL DIAMETER
 Measure the outer diameter of crankshaft pin journal with a micrometer.
 If out of the standard, measure the connecting rod bearing oil clearance. Then use undersize bearing.
OUT-OF-ROUND AND TAPER OF CRANKSHAFT
 Measure the dimensions at four different points as shown in the
figure on each main journal and pin journal with a micrometer.
 Out-of-round is indicated by the difference in dimensions between
“X” and “Y” at “A” and “B”.
 Taper is indicated by the difference in dimension between “A” and
“B” at “X” and “Y”.
 If the measured value exceeds the limit, correct or replace crankshaft.
 If corrected, measure the bearing oil clearance of the corrected main journal and/or pin journal. Then select
main bearing and/or connecting rod bearing.
CRANKSHAFT RUNOUT
 Place a V-block on a precise flat table to support the journals on
the both end of crankshaft.
 Place a dial indicator (A) straight up on the No. 3 journal.
 While rotating crankshaft, read the movement of the pointer on the
dial indicator. (Total indicator reading)
 If it exceeds the limit, replace crankshaft.
CONNECTING ROD BEARING OIL CLEARANCE
Method by Calculation
 Install connecting rod bearings to connecting rod and cap, and tighten connecting rod bolts to the specified
torque. Refer to EM-101, "
Disassembly and Assembly".
 Measure the inner diameter of connecting rod bearing with an
inside micrometer.
(Bearing oil clearance) = (Connecting rod bearing inner diameter)
– (Crankshaft pin journal diameter)
 If the clearance exceeds the limit, select proper connecting rod
bearing according to connecting rod big end diameter and crank-
shaft pin journal diameter to obtain the specified bearing oil clear-
ance. Refer to EM-117, "
Connecting Rod Bearing".
Method of Using Plastigage
 Remove engine oil and dust on crankshaft pin and the surfaces of each bearing completely.
 Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil
holes.
 Install connecting rod bearings to connecting rod and cap, and tighten connecting rod bolts to the specified
torque. Refer to EM-101, "
Disassembly and Assembly".

HOW TO SELECT PISTON AND BEARING
DescriptionINFOID:0000000001381436
 The identification grade stamped on each part is the grade for the dimension measured in new condition.
This grade cannot apply to reused parts.
 For reused or repaired parts, measure the dimension accurately. Determine the grade by comparing the
measurement with the values of each selection table.
 For details of the measurement method of each part, the reuse standards and the selection method of the
selective fitting parts, follow the procedures.

Undersize Bearings Usage Guide
 When the specified connecting rod bearing oil clearance is not obtained with standard size connecting rod
bearings, use undersize (US) bearings.
 When using undersize (US) bearing, measure the connecting rod bearing inner diameter with bearing
installed, and grind the crankshaft pin so that the connecting rod bearing oil clearance satisfies the standard.
