d. Install connecting rod bearing cap (1) as follows.
i. Point arrow mark (2) on cap to crankshaft
pulley side.
ii. Apply engine oil to connecting rod bolts (3).
iii. Tighten all connecting rod bolts to 15 N⋅m (1.5
kgf-m, 11.0 lb-ft).
iv. Retighten them by turning through 45°.
v. Repeat step d) once again.
Tightening torque
Connecting rod bolt (a): Tighten 15 N⋅m
(1.5 kgf-m, 11.0 lb-ft), 45° and 45° by the
specified procedure.
NOTE
Do not turn crankshaft with gauging plastic
installed.
e. Remove connecting rod bearing cap, and using a
scale (2) on gauging plastic envelope, measure
gauging plastic (1) width at the widest point
(clearance).
If clearance exceeds its limit, select connecting
rod bearing referring to "Pistons, Piston Rings,
Connecting Rods and Cylinders Inspection and
Cleaning: For J20 Engine" below mentioned item.
After selecting new bearing, recheck clearance.
Bearing clearance
Standard
0.045 – 0.063 mm
(0.0018 – 0.0025 in.)
I4RH01140037-01
Limit
0.08 mm (0.0031 in.)
I2RH01140167-01
f. If clearance can not be brought to within its limit
even by using a new standard size bearing,
replace crankshaft or regrind crankpin to
undersize as follows.
– Install 0.25 mm undersize bearing to
connecting rod big end.
– Measure bore diameter of connecting rod big
end.
– Regrind crankpin to the following finished
diameter.
Finished Measured big end bore
crankpin = diameter (including
diameter undersize bearing)
– Confirm that bearing clearance is within the
standard value.
NOTE
After checking the connecting rod bearing
clearance, make sure that checking for
"Connecting rod bolt deformation".
• Selection of connecting rod bearings:
NOTE
• If bearing is in malcondition or bearing
clearance is out of specification, select a
new standard bearing according to the
following procedure and install it.
• When replacing crankshaft or connecting
rod and its bearing due to any reason,
select new standard bearings to be
installed referring to numbers stamped on
connecting rod and its cap and/or
alphabets stamped on crank web of No. 3
cylinder.
