Check the condition of the crankshaft main bearings. Refer to the Guideline For Reusable Parts, SEBF8009, "Main and Connecting Rod Bearings" and Guideline For Reusable Parts, SEBV0544, "Engine Bearings and Crankshafts".Note: The number four main bearing in 3114 Engines is the thrust bearing. The number six main bearing in the six cylinder engines is the thrust bearing.
Clean the bearing surfaces in the cylinder block for the main bearings.
Illustration 1 g00678393
Install the upper main bearings (4) in the cylinder block. Ensure that the tab on the back side of the bearing engages with the groove in the cylinder block. Apply clean engine oil on the upper main bearing. Do not put engine oil on the back side of the bearing surfaces.
Illustration 2 g00610100
Typical example
Put clean engine oil on the journals of the crankshaft bearing. Fasten lifting straps and a hoist to crankshaft (1) . Carefully install the crankshaft in the cylinder block.
Clean the bearing surface of the main bearing caps.
Illustration 3 g00678394
Install the lower main bearings (5) in the crankshaft main bearing caps (3) . 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.
Install crankshaft main bearing caps with the bearing tabs on the same side. Ensure that crankshaft main bearing caps have numbers 1 through 7. The numbers should start at the front of the engine. Place clean engine oil or Molylube on the bolt threads and the washers.Note: When the bolts for the rear main bearing cap are tightened, slide the main bearing cap as far forward as possible until the cap is against the bolts. Hold the main bearing cap in this position and tighten the bolts.
Illustration 4 g00609985
Typical example
Install bolts (2) and the washers for main bearing caps (3) . Tighten bolts (2) to a torque of 54 7 N m (40 5 lb ft).
Turn bolts (2) for an additional 90 5 degrees (1/4 turn).
Illustration 5 g00610119
Typical example
Check the end play of crankshaft (1) with Tooling (A) . The end play must be 0.07 mm (0.003 inch) to 0.32 mm (0.013 inch).End By:
Install the pistons and connecting rods. Refer to Disassembly and Assembly, "Pistons and Connecting Rods - Install".
Install the front gear group. Refer to Disassembly and Assembly, "Gear Group (Front) - Install".
Install the crankshaft seal carrier. Refer to Disassembly and Assembly, "Crankshaft Rear Seal Carrier- Remove and Install".
Install the cylinder head. Refer to Disassembly and Assembly, "Cylinder Head - Install".
