D     198-9143     Plastic Gauge     1    
198-9144 Plastic Gauge     1    
198-9145 Plastic Gauge     1    
E     4C-5593     Anti-Seize Compound     1    Note: Install the main bearings without lubricant when the check for the crankshaft main bearing clearance is made. Apply clean engine oil on the crankshaft main bearings for final assembly.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Illustration 1 g01096656
Install the lower half of main bearing (3) on main bearing cap (1) .
Illustration 2 g01096660
Install the upper half of the main bearing by installing Tooling (A) in oil hole (4) in the crankshaft. Use Tooling (B) in order to turn the crankshaft in the direction which will install the upper half of the main bearing. The tab of the main bearing must be installed last.
Illustration 3 g01096652
Install thrust plates (2) for the center main bearing.Note: Install thrust plates (2) with the identification "Block Side" toward the cylinder block.Note: Thrust plates (2) will only be located on the center main bearing.
Illustration 4 g00888082
Note: Do not rotate the crankshaft when Tooling (D) is installed.
Use Tooling (D) in order to check the bearing clearance.
Install main bearing cap (1). Apply Tooling (E) to the bolts. Install the bolts in main bearing cap (1). The tabs must be on the same side when the two halves of the main bearing are installed. The Arrow must point toward the front of the engine.Note: If the bolts for your main bearing cap are twelve point head bolts, the torque is 450 14 N m (332 10 lb ft). If the bolts for your main bearing cap are hex head bolts, the torque is 258 14 N m (190 10 lb ft).
Tighten the bolt on the tab end of main bearing cap (1). Next, tighten the other bolt on main bearing cap (1). Put a mark on each bolt and main bearing cap (1). Tighten the bolt on the opposite side of the tab end of main bearing cap (1) for an additional 120 5 degrees. Next, tighten the bolt on the tab end of main bearing cap (1) for an additional 120 5 degrees.
Check the end play of the crankshaft with Tooling (C). Ensure that Tooling (C) is against a machined surface. The end play is controlled by the thrust plates of the center main bearing. The end play with new thrust plates (3) must be 0.13 to 0.50 mm (0.005 to 0.020 inch). The maximum permissible end play with used thrust plates is 0.89 mm (0.035 inch).End By: Install the engine oil pump. Refer to Disassembly and Assembly, "Engine Oil Pump - Install".
