3) Install connecting rod fitted with bearing to crankshaft
and measure the side clearance (thrust clearance). Replace
connecting rod if the side clearance exceeds the specified limit_
Connecting rod side clearance:
Fig. 240
Standard
0.070 - 0.330 mm (0.0028 - 0.0130 in)
Limit
0.4 mm (0.016 in)
4) Inspect connecting rod bearing for scar, peeling, seizure,
melting, wear, etc.
5) Measure the oil clearance on individual connecting rod
bearings by means of plastigauge according to the following
procedure.

(1) Wipe off oil, dust, etc. on the surfaces to be measured.
(2) Cut the plastigauge to the width of the bearing, place
it on the crankpin parallel with the crankshaft axis, and
install connecting rod. Tighten connecting rod nuts to
the specified torque.
Tightening torque:
39 - 42 N·m (4.0 - 4.3 kg-m, 29 - 31 ft-Ib)
During this measurement, do not allow relative movement
between the crankpin and connecting rod.
(3) Remove connecting rod and measure the width of the
plastigauge with the scale printed on the plastigauge case.
If any oil clearance is not within specification, replace the
defective bearing with a new one of standard size or
undersize as necessary, and replace or recondition the
crankshaft as necessary. (See the table below.)
