• CONNECTING ROD BEARING OIL CLEARANCE
1) Clean the crank pin and the bearing of the connecting rod
cap assembly. Check the crank pin and the bearing for wear
or damage.
2) Install the crankshaft on the cylinder block. Install the
connecting rod cap assembly on the connecting rod, and
tighten the connecting rod nut to the specified torque (P.
10-26).
3) Remove the connecting rod cap assembly and set a
plastigauge on the crank pin as shown.
• Set the plastigauge in the axial direction.
• Avoid the oil passage in the bearing journal to set the
plastigauge.
4) Reinstall the connecting rod cap assembly on the
connecting rod, and tighten the connecting rod nut to the
specified torque (P. 10-26).
• Tighten the connecting rod nut with care not to turn the
crankshaft and/or the connecting rod.
5) Remove the connecting rod cap assembly. Measure the
compressed width of the plastigauge using the scale
printed on the bag of the plastigauge.
• Measure the widest width on the plastigauge.
6) If the measurement exceeds the service limit, replace with
an undersize bearing by referring to the connecting rod
bearing selection table (P. 10-17). Recheck the connecting
rod bearing oil clearance.
If the measurement still exceeds the service limit, replace
the crankshaft with a new one.
