(A) Thickness gauge
(B) Connecting rod
3) Install the connecting rod fitted with bearing to
crankshaft and measure the side clearance (thrust
clearance). If side clearance exceeds the limit, re-
place the connecting rod.
Connecting rod side clearance:
Standard
0.070 — 0.330 mm (0.0028 — 0.0130 in)
4) Inspect the connecting rod bearing for scar,
peeling, seizure, melting, wear, etc.
5) Measure the oil clearance on individual connect-
ing rod bearings by means of plastigauge. If any oil
clearance is not within the specification, replace the
defective bearing with a new one of standard size
or undersize as necessary. (See the table below.)

6) Inspect the bushing at connecting rod small end,
and replace if worn or damaged. Also measure the
piston pin clearance at the connecting rod small
end.
Clearance between piston pin and bushing:
Standard
0 — 0.022 mm (0 — 0.0009 in)
7) Replacement procedure is as follows.
(1) Remove the bushing from connecting rod
with ST and press.
(2) Press the bushing with ST after applying oil
on the periphery of bushing.
