CONNECTING ROD BIG END I.D.
Set the connecting rod lower and connecting rod
bearings to the connecting rod upper and tighten the
connecting rod bolts to the specified torque.

surface and connecting rod bearings.
Place a piece of plastigauge on the crank pin, install the
connecting rod upper, the connecting rod lower and the
connecting rod bearings, and tighten the connecting rod
bolts to the specified torque.
• Do not rotate the crankshaft while the plastigauge is
in place.
Remove the connecting rod and measure the
