Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: For information on the reusability of the crankshaft main bearings, refer to the Guideline For Reusable Parts And Salvage Operations, SEBF8009, "Main and Connecting Rod Bearings".Note: Place clean engine oil on the crankshaft main bearings prior to assembly. The tabs on the back side of the crankshaft main bearings must fit in the grooves of main bearing caps and the cylinder block.

Use Tooling (A) and install the upper halves of the crankshaft main bearings in the cylinder block. Do not put oil on the back of the crankshaft main bearing.
Illustration 2 g00610152
Install the lower halves of the crankshaft main bearings in crankshaft main bearing caps (2). Do not put oil on the back of the crankshaft main bearing.

Crankshaft main bearing caps should be installed with the part number toward the right side of the engine. Crankshaft main bearing caps are to be identified by stamped numbers 1 through 7 located on the bottom surface. The thrust plate is to be installed in the original position on the crankshaft main bearing.
Oil grooves are machined in the saddles of the cylinder blocks of all 3114 engines and earlier 3116 engines. No oil grooves are machined in the saddles of the cylinder block on later 3116 engines and all 3126 engines.
Install the bearing caps with the bearing tabs on the same side. A six cylinder engine has an order of 1 through 7 (front to rear). A four cylinder engine has an order of 1 through 5 (front to rear). Place crankshaft main bearing caps (2) in position on the cylinder block. Place clean engine oil or Molylube on the bolt threads and the washer face. Install bolts (1).
Tighten bolts (1) to a torque of 54 7 N m (40 5 lb ft). Tighten each bolt (1) for an additional 90 5 degrees (1/4 turn).

Check the end play of the crankshaft with Tooling (B). The end play must be 0.07 mm (0.003 inch) to 0.32 mm (0.013 inch).End By:
Install the engine oil pump. Refer to Disassembly and Assembly, "Engine Oil Pump - Install".
Install the engine balancer shaft on 3114 engines. Refer to Disassembly and Assembly, "Engine Balancer Shaft - Remove and Install".
