 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.

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, "

 Tighten main muffler mounting bracket bolts in numerical order as
shown in the figure.
CAUTION:
 Always replace exhaust tube gasket s with new ones when reassembling.
 If heat insulator is badly deformed, repair or repl ace it. If deposits such as mud pile up on the heat
insulator, remove them.
 When installing heat insulator avoid large gaps or interference between heat insulator and each
exhaust pipe.
 Remove deposits from the sealing surface of each connection. Connect them securely to avoid
gases leakage.
 Temporarily tighten mounting nuts on the exhaust manifold side and mounting bolts on the vehicle
side. Check each part for unusual interference, an d then tighten them to the specified torque.
 When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/left
directions.
INSPECTION AFTER INSTALLATION
 Make sure clearance between tail tube and bumper is even.
 With engine running, check exhaust tube joints for gas leakage and unusual noises.
 Check to ensure that mounting brackets and mount ing rubbers are installed properly and free from undue
stress. Improper installation could resu lt in excessive noise and vibration.
