Measure the connecting rod twist.
With the big-end arbor [A] still on V blocks [C], hold the
connecting rod horizontal and measure the difference in
the height of the arbor [B] above the surface plate over
a 100 mm (3.94 in.) length of the arbor to determine the
amount of connecting rod twist.
If the connecting rod twist exceeds the service limit, the
connecting rod must be replaced.
Connecting Rod Twist
0.2/100 mm (0.008/3.94 in.)
Connecting Rod Big End Side Clearance Inspection
Measure the connecting rod big end side clearance.
Insert a thickness gauge [A] between the big end [B] and
either crank web [C] to determine the clearance.
Connecting Rod Big End Side Clearance
0.13 ∼ 0.38 mm (0.0051 ∼ 0.0150 in.)
0.50 mm (0.02 in.)
If the clearance exceeds the service limit, replace the con-
necting rod with a new one and then check the clearance
again. If the clearance is too large after connecting rod
replacement, the crankshaft must be replaced.
Connecting Rod Big End Bearing Insert/Crankpin
Measure the bearing insert/crankpin clearance using a
Remove the connecting rod big end caps and wipe each
bearing insert and crankpin surface clean of oil.
Cut strips of plastigage to bearing insert width, and place
a strip on the crankpin for each connecting rod parallel to
the crankshaft so that the plastigage will be compressed
between the crankpin and the bearing insert.
Install the connecting rod big end caps and tighten the big
end cap nuts to the specified torque.
Torque - Connecting Rod Big End Cap Nuts: 36 N·m (3.7
kgf·m, 27 ft·lb)
Do not move the connecting rod and crankshaft during
