(1) Tooling (A) must be used in order to install the front main bearing cap with the front housing and the engine oil pump in place.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Illustration 1 g00554540
Clean upper main bearing (4) and lubricate the bearing surface with clean engine oil. Note: Ensure that the upper halves of the main bearings are installed so that the bearing tabs fit into the notch in the cylinder block.
Only the upper half of the main bearing has lubrication holes. Make sure the upper half of the main bearing is installed correctly in the cylinder block to ensure proper lubrication.
Slide upper main bearing (4) into position between the crankshaft journal and the cylinder block.
Illustration 2 g00554539
Clean main bearing cap (2) and lower main bearing (3). Lubricate the bearing surface of lower main bearing (3) with clean engine oil. Note: Ensure that the lower halves of the main bearings are installed so that the bearing tabs fit into the notch in the main bearing caps.
Install lower main bearing (3) in main bearing cap (2).
Illustration 3 g00554537
Make sure that the bearing tabs on both halves of the main bearings are located on the same side. Install main bearing caps (2).
Lubricate the threads of bolts (1) with clean engine oil.
Install bolts (1). Tighten bolts (1) to a torque of 250 N m (185 lb ft). Use Tooling (A) to tighten the bolts for the front main bearing cap.
Repeat Steps 1 through 7 for the remaining main bearings.
Rotate the crankshaft in order to ensure that the crankshaft turns freely.

Typical example
Check the crankshaft end play. Use a prybar to move the crankshaft toward the rear of the engine. Install Tooling (B) and zero the dial indicator. Move the crankshaft with the prybar toward the front of the engine. Measure the crankshaft end play. The maximum permissible crankshaft end play is 0.51 mm (0.020 inch). Note: If the crankshaft was not removed for the rear main bearing removal, the following components must be installed: bridge assembly, rear oil seal housing, flywheel housing and flywheel.End By:
Install the engine oil relief valve and the oil strainer. Refer to Disassembly and Assembly, "Engine Oil Relief Valve - Remove and Install".
