Tightening Torques and Sequences

Main Bearing Cap Torque and Sequence
Tighten the bearing cap bolts, and then the bearing cap side bolts to the specified torque in the sequence as shown. Repeat the torque sequence again to ensure the bolts are properly torqued.





Rod Bearing Cap Torque and Sequence
Tighten the bolts to 20 N-m (2.0 kgf-m, 14 lbf-ft).
Mark the connecting rod and the bolt head as shown.
Tighten the bolt until the mark on the bolt head lines up with the mark on the connecting rod (turn the bolt 90 °).





Connecting Rod Bolt Reuse/Replace
Measure the diameter of each connecting rod bolt at point A and point B.
Calculate the difference in diameter between point A and point B.
If the difference in diameter is out of specification, replace the connecting rod bolt.








Crankshaft Pulley Torque
Crankshaft pulley, tighten the bolt to 64 N-m (6.5 kgf-m, 47 lbf-ft).
Then tighten the bolt an additional 60 °.
