ROO
1)
Replace the connecting rod,
if
the large or small
end thrust surface is damaged.
2)
Check for bend or twist using a connecting rod
aligner. Replace the connecting rod
if
the bend or
twist exceeds the limit.

3)
Install the connecting rod fitted with bearing to
crankshaft and measure the side clearance (thrust
clearance). Replace the connecting rod
if
the side
clearance exceeds the specified limit.

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 specification, replace the
defective bearing with a new one of standard size
or undersize as necessary. (See the table below.)
