 Remove main bearing caps and bearings, and using the scale on
the plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the “Method by Calculation”.
MAIN BEARING CRUSH HEIGHT
 When main bearing cap is removed after being tightened to thespecified torque with main bearings installed, the tip end of bearing
must protrude. Refer to EM-123, "
Disassembly and Assembly" for
the tightening procedure.
 If the standard is not met, replace main bearings.
CONNECTING ROD BEARING CRUSH HEIGHT
 When connecting rod bearing cap is removed after being tightened to the specified torque with connecting rod bearings installed, the
tip end of bearing must protrude. Refer to EM-123, "
Disassembly
and Assembly" for the tightening procedure.
 If the standard is not met, replace connecting rod bearings.
MAIN BEARING CAP BOLT OUTER DIAMETER
 Measure the outer diameters (“d1”, “d2”) at two positions as shown
in the figure.
 If reduction appears in “A” range, regard it as “d
2”.
 If it exceeds the limit (large difference in dimensions), replace main bearing cap bolt with new one.

 If corrected, measure the bearing oil clearance of the corrected main journal and/or pin journal. Then select
the main bearing and/or connecting rod bearing. Refer to "MAIN BEARING OIL CLEARANCE" and/or
"CONNECTING ROD BEARING OIL CLEARANCE".
CRANKSHAFT RUNOUT
 Place V-block on precise flat table, and support the journals on the both end of crankshaft.
 Place dial indicator straight up on the No. 3 journal.
 While rotating crankshaft, read the movement of the pointer on 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-
242, "Disassembly and Assembly" for the tightening procedure.
 Measure the inner diameter of connecting rod bearing with inside micrometer.
(Bearing oil clearance) = (Connecting rod bearing inner diameter) –
(Crankshaft pin journal diameter)
 If the calculated value exceeds the limit, select proper connecting rod bearing according to connecting rod
big end diameter and crankshaft pin journal diameter to obtain the specified bearing oil clearance. Refer to
EM-250, "
How to Select Piston and Bearing".
Method of Using Plastigage
 Remove oil and dust on crankshaft pin journal and the surfaces of each bearing completely.
 Cut 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-242, "
Disassembly and Assembly" for the tightening procedure.
CAUTION:
Do not rotate crankshaft.
 Remove connecting rod bearing cap and bearing, and using scale
on plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the “Method by Calculation”.

CYLINDER BLOCK
 Install main bearings to cylinder block and main bearing caps, and
tighten main bearing cap bolts with main bearing to the specified
torque. Refer to EM-242, "
Disassembly and Assembly" for the
tightening procedure.
 Measure the inner diameter of main bearing with bore gauge.
(Bearing clearance) = (Main bearing inner diamet er) – (Crankshaft main journal diameter)
 If the calculated value exceeds the limit, select proper main bearing according to main bearing inner diame-
ter and crankshaft main journal diameter to obtain the specified bearing oil clearance. Refer to EM-250,
"How to Select Piston and Bearing".
Method of Using Plastigage
 Remove oil and dust on crankshaft main journal and the surfaces of each bearing completely.
 Cut plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil
holes.
 Install main bearings to cylinder block and main bearing caps, and tighten main bearing bolts with main bear- ing to the specified torque. Refer to EM-242, "
Disassembly and Assembly" for the tightening procedure.
CAUTION:
Do not rotate crankshaft.
 Remove main bearing caps and bearings, and using scale on plas- tigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the “Method by Calculation”.
CRUSH HEIGHT OF MAIN BEARING
 When main bearing cap is removed after being tightened to the specified torque with main bearings installed, the tip end of bearing
must protrude. Refer to EM-242, "
Disassembly and Assembly" for
the tightening procedure.
 If the standard is not met, replace main bearings.
