Apply a light coat of clean engine oil to the connecting rod bearing surfaces and to the connecting rod journals. Install the connecting rods onto the connecting rod journals.
Remove the protective tape or rubber tubing on connecting rod bolts (6).
Install the lower half of the connecting bearings into the corresponding connecting rod caps and install connecting rod caps (2) .Note: Align the tabs on the back of the connecting rod bearings with the tab grooves in the connecting rod caps.
Install connecting rod cap nuts (1) . Tighten the nuts to a torque of 54 5 N m (40 4 lb ft).
Check for free crankshaft rotation by rotating the crankshaft for two complete revolutions. Use Tool (A) on crankshaft pulley nut (3) in order to rotate the crankshaft.End By:
