Note: The number six main bearing is the thrust bearing.
1.Clean the bearing surfaces in the cylinder block for the main bearings. Apply clean engine oil on the upper main bearing. Do not put engine oil on the back side of the bearing surfaces. Install the upper main bearing in the cylinder block. Ensure that the tab on the back side of the bearing engages with the groove in the cylinder block.
2.Put clean engine oil on the journals of the crankshaft bearing. Attach a suitable lifting device to crankshaft (1) . The weight of crankshaft (1) is approximately 60 kg (132 lb). Carefully install the crankshaft in the cylinder block.
3.Clean the bearing surface of the main bearing caps. Install the lower main bearing in the crankshaft main bearing caps. Ensure that the tab on the back side of the bearing engages with the groove in the main bearing cap. Apply clean engine oil on the lower main bearing. Do not put engine oil on the back side of the bearing surfaces.
4.Install crankshaft main bearing caps with the part numbers toward the right hand side of the cylinder block. The numbers should start at the front of the engine. Place clean engine oil or Molylube on the bolt threads and the washers.
5.Install the bolts for main bearing caps (2) . Tighten the bolts to a torque of 54 ± 7 N·m (40 ± 5 lb ft).
6.Turn the bolts for an additional 90 ± 5 degrees (1/4 turn).
7.Install connecting rod caps (3) . Refer to Disassembly and Assembly, “Pistons and Connecting Rods – Install”.
8.Check the end play of crankshaft (1) with Tooling (A) . The end play must be 0.07 to 0.32 mm (0.003 to 0.013 inch).
a.Install the front housing. Refer to Disassembly and Assembly, “Housing (Front) – Install”.
b.Install the engine oil pump. Refer to Disassembly and Assembly, “Engine Oil Pump – Install”.
c.Install the flywheel housing. Refer to Disassembly and Assembly, “Flywheel Housing – Remove and Install”.
