• Connecting rod bearing clearance:
a. Before checking bearing clearance, clean bearing
and crank pin.
b. Install bearing in connecting rod and bearing cap.
c. Place a piece of gauging plastic (1) to full width of
crank pin as contacted by bearing (parallel to
crankshaft), avoiding oil hole.
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" below mentioned item.
After selecting new bearing, recheck clearance.

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
